More InformationWhich doctor should perform penis enlargement surgery?
Why penis enlargement is sometimes not a harmless procedure
Many patients believe that surgical penis enlargement (technical term: penis augmentation) is a simple procedure without risk. It can be, but it doesn’t have to be. Irresponsible advertising promises made by doctors on the subject of penis enlargement in recent times have no scientific basis. Read more about this below under “Are there other methods for penis enlargement“.
Competent advice and the safe, effective performance of penis enlargement surgery should only be carried out by a doctor who is personally experienced in this procedure. This is what we specialize in in Darmstadt. We have been using evidence-based methods for effective penis enlargement for years.
Why is many years of experience in penis enlargement absolutely essential?
The study situation on surgical penis enlargement is poor and shows contradictory results. Further research and the creation of guidelines for penis enlargement surgery are necessary. When performed with extensive experience and using evidence-based techniques, penis enlargement surgery produces very good results, with low risk and high patient satisfaction (Citation: 1).
Why not every doctor can perform penis enlargement surgery?
Penis enlargement is not included in the training catalog of a urology specialist (Citation: 2, 3)
The assumption by patients that every specialist doctor is trained in penis enlargement surgery is wrong. Penis enlargement surgery is a highly complex specialist operation and also a niche operation.
When an experienced doctor performs penis enlargement surgery and uses evidence-based methods of high quality:
- Very good results in both the flaccid and erect state
- Low risk with penis enlargement
- Very high patient satisfaction after penis enlargement surgery
Important scientific findings on penis enlargement:
- Current studies emphasize the particular importance of the personal experience of the operating surgeon and correct patient selection. To prevent risks and achieve good and lasting results (Citation: 4, 5, 6, 7, 8, 9, 10)
- In penis enlargement, the same technique produces very different results, depending on the surgeon (Citation: 9). This finding shows that an inexperienced surgeon is often to blame for poor results.
- It depends on the personal case numbers of the surgeon, not on the case numbers of the clinic or the title of the doctor (Citation: 10, 11).
Presumption: Perhaps the attitude of the urological society towards penis enlargement is negative because its members have carried out penis enlargement without the necessary training and experience and have therefore obtained poor and contradictory results.
What are the risks of penis enlargement surgery?
Every medical procedure carries risks. Penis enlargement is no exception. However, thanks to our specialization, precise surgical technique and decades of experience, penis enlargement is associated with a very low risk of complications. Our patients particularly appreciate the fact that we are open and transparent about the possible side effects of penis enlargement surgery. Please read the following information to find out why we do not use certain techniques.
Conclusion: We focus on quality, sustainability and your long-term satisfaction with penis enlargement. That’s why we avoid trends and advertising promises when it comes to penis enlargement. We also don’t dig up long-known techniques to sell them as novelties – which unfortunately happens time and again. We concentrate on what we do best: safe, natural and permanent penis enlargement with medical excellence.
Penis enlargement even when aroused?
Yes, penis enlargement also in erection
Our experience and the application of the right evidence-based technique also leads to penis enlargement in length and girth in erection. This has been proven by independent scientific studies (Citation: 1).
Some doctors claim that penis enlargement with an erection is not possible with this operation. This is definitely false. We would like to re-emphasize the importance of experience and expertise for the results of penis enlargement. Even when using the identical technique for penis enlargement, the results vary depending on the doctor treating you (Citation: 9)
Our approach to effective penis enlargement combines a high degree of experience, skill, medical precision, the highest quality materials, human empathy and the utmost discretion. At our clinic in Darmstadt, we focus on you as a person and you will be looked after by a team that has specialized in penis enlargement for decades.
What is our specialty in penis enlargement?
The founding father of UGRS, Dr. Jörn Siana, who is responsible for penis enlargement, performed surgical penis enlargement as early as 1993 and played a decisive role in developing the modern technique for penis lengthening and thickening. For years, he was socially criticized for performing this operation because it was considered unseemly to question the perfection of a penis and offer an operation to improve it.
In 1995, Dr. Jörn Siana also developed the first penis extender for use after surgery, the JES Extender named after him.
UGRS doctors and the UGRS team have 20 years of experience, expertise and skill in penis enlargement compared to most other surgeons in Germany.
Milestones of our expertise:
- 1993: First surgical penis enlargement by Dr. Jörn Siana
- 1995: Development of the first penis extender (JES Extender) for use after penis enlargement surgery
- 2006-today: Over 8,000 documented penis enlargement operations
Our evidence-based treatment approach to penis enlargement combines:
- Highest level of experience (8,000+ operations)
- Medical precision through evidence-based methods
- High-quality materials
- Human empathy
- Maximum discretion for penis enlargement
- Specialized penis enlargement team
What results can we achieve with penis enlargement in Darmstadt?
Our specially developed technique for penis enlargement enables both lengthening and thickening of the penis in a single procedure – permanently and without the use of foreign materials. Our method is based exclusively on the body’s own tissue. This allows us to achieve a natural penis enlargement result that is both visually and functionally impressive.
- Extension: approx. 3 - 6 cm (up to 14.2 cm additionally possible in individual cases)
- Thickening: approx. 2.8 cm increase in circumference (in aesthetic proportion)
We offer professional penis enlargement as an outpatient procedure under local anesthesia with twilight sleep; general anesthesia is not necessary. Thanks to our “speed recovery” technique, you will be ready for everyday life again quickly after penis enlargement.
Your advantages at a glance
- Permanent penis enlargement without foreign materials such as silicone or filler
- Combination of penis enlargement and penis thickening in one procedure

What is the organizational procedure for penis enlargement in Darmstadt?
Transparency from the initial consultation to aftercare
Penis enlargement surgery should never be undertaken lightly. That’s why every penis enlargement treatment begins with a detailed personal consultation. Together with you, we clarify your goals, discuss possible results and openly answer all questions about risks, the healing process and the technique. Your decision on penis enlargement should be informed and well-founded.
Before the penis enlargement operation
- Anonymous, free and non-binding advice, by telephone or e-mail
- Medical evaluation of your health situation
- Detailed consultation with the surgeon responsible for penis enlargement at our clinic
- Discussion of your initial anatomical situation and medical history
- Clarification of the process and the exact procedure
The penis enlargement procedure itself
- Duration: approx. 90 minutes
- Local anesthesia with gentle twilight sleep. Naturally performed by our experienced anesthetists. General anesthesia is possible on request.
- Gentle keyhole technique
- You can find out how we perform the operation under the menu item on our lengthening and thickening techniques
After the penis enlargement operation (on the day of the operation)
- Recovery time on site after the operation (approx. 1 hour)
- Return to the hotel (hospital stay possible but not necessary)
After the penis enlargement operation (day after)
- Wound control
- You will receive detailed aftercare instructions (e.g. abstaining from sport and sex for approx. 5 weeks)
- Follow-up appointments are not necessary but are of course possible at any time free of charge
Thanks to our special scientifically based technique for penis enlargement, many patients report minimal pain, rapid recovery and a high level of everyday fitness just a few days after penis enlargement.
What type of anesthesia is used for penis enlargement at our clinic in Darmstadt?
We have been performing penis enlargement on an outpatient basis in twilight sleep for around 20 years. Our experience and expertise make this possible.
You will experience the penis enlargement operation in a relaxed manner, will not notice anything and will be fit again very quickly.
Of course, the anesthetist is always present during penis enlargement. He – and only he – administers the twilight anesthesia, not the surgeon. We therefore do not use twilight anesthesia instead of general anesthesia for penis enlargement in order to save the anesthetist during penis enlargement. But because it is more comfortable and much gentler for the patient.
Scientific basis for these benefits:
What technique do we use for penis enlargement?
Scientifically superior results
Our penis enlargement technique as part of surgical penis enlargement is based on the latest scientific findings, evidence-based medicine and decades of experience.
Why pure ligamentolysis is not sufficient for penis enlargement: Studies have clearly shown that the original surgical technique of pure ligamentolysis achieves poorer results (Citation: 16).
Our combined technique: UGRS doctors have therefore been using a combined penis enlargement technique that has been modified over the years since 1993:
- Ligamentolysis with subsequent
- Internal swivel flap plastic in a modified form
- Additional special features (not publicly disclosed for quality reasons)
- Only the body's own material (no “silicone ball”)
Important to know: you can find out why we generally do not use silicone implants for penis enlargement under the menu item “Why don’t we use other techniques for penis enlargement?”.
Scientifically proven benefits: Our combined lengthening technique as part of penis enlargement achieves better results, especially when performed professionally by an experienced doctor (Citation: 1, 9, 16).
Explained in patient-friendly terms: We take out a little more of the inner part of the penis, which lengthens the outer part.
We used to describe the ratio as 50:50. If you read this on other websites, you know exactly who has copied from our old penis enlargement texts. Probably to pretend to use the same penis enlargement technique as we do, or because of their own lack of knowledge.
Important: No incisions are made in the penis, so there are no risks in this regard here in Darmstadt.

What technique do we use for penis thickening?
Gold standard method: Autologous fat tissue transplantation according to Dr. Siana
The method we use for penis thickening as part of penis enlargement was developed by UGRS founding father Dr. Jörn Siana. He had special surgical instruments produced by the industry for this purpose – proof of our innovative strength in penis enlargement.
This is how our proven penis thickening technique works:
- Harvesting: Living adipose tissue with stem cells from the thigh or abdomen
- Preparation: Nowadays it would be described as a mixture of macrofat, microfat, nanofat plus stem cells
- Transplantation: Precisely coordinated injection under the skin of the penis
- Healing: Natural fusion with surrounding tissue
Our method was described early on as the gold standard for penis thickening (see Krupp/Rennekampff “Plastische Chirurgie”, medical reference book).
Experience determines the result: This technique as part of penis enlargement requires a great deal of experience. This is the only way to achieve natural results without unsightly dents, lumps or loss of sensation. Thanks to continuous further development and decades of experience, we ensure maximum safety and patient satisfaction.
Scientifically proven advantages:
- When performed professionally and with the correct patient selection, this technique of autologous fat tissue transplantation for penis thickening as part of penis enlargement leads to very good and long-lasting results, with low risk (Citation: 17, 18, 19).
- Processed fatty tissue is now successfully used in plastic surgery in many areas of the body (Citation: 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30), which underlines the safety and professionalism of our technique.
Thanks to the continuous development of our penis enlargement technique and years of experience, we are able to offer the highest level of safety, sustainability and patient satisfaction.
Medical ethics before profit: While dubious doctors often exaggerate, we rely on scientifically sound moderation for optimal results with minimal risks. We perform the thickening in aesthetic proportion to the lengthening achieved.
Significantly more would be possible with penis enlargement, but is risky: the risk increases significantly from a quantity of approx. 300 ml of transplanted fatty tissue (Citation: 31).
Why we reject other penis thickening techniques
Other penis thickening techniques often have hidden, sometimes significant risks and side effects. Hyaluronic acid on the penis can even cause fatal complications. This is why we in Darmstadt only use our tried-and-tested autologous fat technique for penis thickening as part of a penis enlargement procedure. According to our experience and scientific findings, this has a lower risk than other fillers when performed correctly (Citation: 21).

Why don't we use hyaluronic acid, silicone or artificial skin?
Concealed risks and major dangers
Since around 2014, other sometimes questionable doctors have discovered penis enlargement for themselves and advertise with irresponsible, scientifically unproven promises and clear false statements. We take a stand on the other penis enlargement techniques in the order we feel they are most dangerous for patients.
Scientific evaluation of other methods according to risk
In the following, we list methods offered as “alternatives” to the penis enlargement technique we use and evaluate them according to scientific knowledge and personal experience.
Hyaluronic acid
Hyaluronic acid is advertised as a harmless, risk-free, cost-effective alternative to complex penis enlargement surgery. In our opinion, this is irresponsible. Scientific findings support our opinion.
What key facts speak against hyaluronic acid for penis enlargement?
The key facts here are:
- No approval: There is (as of 5/2025) no hyaluronic acid product explicitly approved for penis enlargement. It is used by the respective doctor in so-called off-label use, i.e. the manufacturer assumes no liability, which can be of enormous consequence for the patient in the event of complications during penis enlargement.
- Deaths documented: There are even scientifically reported deaths after using hyaluronic acid for penile thickening (Citation: 32, 33)
Risk-free and harmless looks different!
What are the known risks of hyaluronic acid?
Hyaluronic acid can, depending on the area of application and the quality of the application:
- Infections
- Biofilms caused by bacteria, especially when large quantities are used
- Necrosis (dying off) of the skin
- and in particular cause vascular occlusions
Hyaluronic acid and its risks have long been known (Citation: 34, 35, 36, 37).
When applied to the face, blindness occurred repeatedly (Citation: 38, 39).
What are the consequences of off-label use of hyaluronic acid on the penis?
It can be assumed that vascular occlusion in the penis as a side effect of hyaluronic acid treatment for penis enlargement leads to erectile dysfunction, possibly permanently.
This assumption was made in particular because vascular occlusions in the face caused by hyaluronic acid also affected veins as a late reaction (Citation: 40). Veins in the penis are responsible for erection control.
Is hyaluronic acid really a cost-effective alternative for penis enlargement?
The statement that it is a cost-effective alternative to penis enlargement is also not true. It is in fact a dubious advertising promise.
Why the cost statement is wrong:
Hyaluronic acid is a degradable filler, which means that the respective treatment for penis enlargement must be repeated at intervals. This means that the costs are not only incurred once, but several times and quickly add up over time.
As the penis skin is thin and the amount of hyaluronic acid required for the treatment is relatively large, the penis skin wears out over time. This means that if the replenishments are not carried out, there is a risk that the penis skin will be too large and hang down wrinkled. This makes the penis look old and misshapen.
What is problematic about brand names for hyaluronic acid for penis enlargement?
We find it reprehensible for doctors to register brand names for the use of hyaluronic acid for penis enlargement if they use these brand names as long as hyaluronic acid on the penis has not been approved.
The brand name “AndroFill”, for example, does not describe a product approved for penis enlargement, as patients repeatedly think when they ask us about it, but merely the technique of holding the needle during injection. Due to the fact that patients repeatedly believe it to be an independent approved product for penis enlargement, we can only assume that this was exactly the intention.
Important to know: No medical procedure is without risk. It becomes problematic when risks are concealed to promote sales or the existence of products is feigned in the eyes of patients.
So why don't we use hyaluronic acid?
Our method for penis thickening with autologous fat as part of a penis enlargement is permanent. Fatty tissue is also the body’s own living tissue. Hyaluronic acid is a liquid that breaks down again.
Silicone sleeves
In the USA in particular, silicone plates for penis enlargement are offered under different product names, even by the same manufacturer. Similar to hyaluronic acid, these products are also often marketed as simple, low-risk and with equivalent results.
What important scientific findings are there on silicone sleeves?
Important scientific findings:
- Enlargement in the flaccid state: The silicone sleeves often only lead to penis enlargement in the flaccid state (Citation: 41). In our experience, many patients are not even aware of this.
- Significant risks: The insertion of silicone sleeves can involve considerable risks and complications. These include biofilm formation due to bacteria, infections and foreign body reactions (Citation: 42, 43). These risks can also lead to shortening and curvature of the penis (Citation; 44). Foreign materials, especially in mechanically stressed areas such as the penis, can also slip out of place.
- Risk of erosion: Since the penis is a highly flexible organ and the silicone plate is not, the implant may puncture the skin (erosion) or disrupt underlying structures that are important for the function of the penis. A very comprehensive scientific study on the subject of silicone sleeves for penis enlargement comes to the conclusion that the risk of erosion in particular was probably underestimated in earlier publications (Citation: 45)
So why don't we use silicone sleeves for penis enlargement?
Our technique leads to penis enlargement in a flaccid AND erect state and does not involve the risks of foreign material.
While the autologous fat tissue transplantation we use is a minimally invasive procedure, the insertion of a silicone plate requires a more extensive procedure with the corresponding surgical risks.
Silicone balls
A silicone ball for penis enlargement is also an artificial foreign body and there is a risk of biofilm formation, infection, foreign body reaction and systemic reaction to the insertion of silicone (Citation: 42, 43, 46).
What are the mechanical risks of silicone balls during sexual intercourse?
There is also considerable mechanical force at the point between the penis and the pelvic bone during sexual intercourse. In the worst case, the implant can slip.
Conclusion:
Our lengthening technique as part of a penis enlargement procedure uses the body’s own tissue. This eliminates the additional risks associated with artificial material.
Thanks to our experience and expertise, we do not need to use a silicone ball for penis enlargement.
Artificial skin strips or own skin strips
The study situation on this new penis enlargement procedure is extremely poor. Some studies report an implausibly low complication rate and only a small increase in the circumference of the penis when erect (Citation: 47).
What contradictory study results are there on skin strips for penis enlargement?
Other studies report a high complication rate, as we would expect, because infections, unsightly appearance and penile curvature can occur after penis enlargement (Citation: 48, 49, 50). There are also reports that patients who have undergone this new technique regret it (Citation: 49).
So why don't we use skin strips for penis enlargement?
We consider the risk of infection to be too high. Your own skin strips for penis enlargement must also be taken from a place where scars occur – in addition to the risks on the penis itself.
Vein implants
Intervention in the organ:
These vein implants or vein interpositions for penis enlargement are a profound intervention in the penis itself. The cavernous body is altered in the depth of the organ. If successfully performed without the sometimes considerable risks, this results in penis enlargement exclusively in the form of an erection (Citation: 51).
For us, the risk and expense of this experimental procedure for penis enlargement is disproportionate to the result.
Options for penis enlargement without surgery
We do not have to resort to science to answer this question, but can answer it on the basis of general logic and common knowledge:
If there was something simple and inexpensive for penis enlargement, we doctors would not be in the operating theater from morning to night performing penis enlargement surgery.
Hormone pills or hormone patches
If hormone pills or hormone patches caused penis enlargement, many professional bodybuilders and millions of older men who take these pills due to age-related hormonal weakness would have very large penises because they take these pills for years. The opposite is the case.
Penis stretching belts
With regard to penis stretching belts, it should be noted that the best-known one refers to an FDA approval that does not even exist and presents a study on the effectiveness of penis enlargement that firstly relates to a different product and secondly is controversial in the scientific community.
Whether it is credible that it would be risk-free to pull the penis to the side for hours every day for 6 months or longer is a question you can surely answer for yourself.
What happens before & after penis enlargement surgery?
Well prepared = relaxed through the procedure.
Good preparation and clear aftercare are crucial for an optimal surgical result in penis enlargement. Our aim is for you to feel well informed, safe and accompanied at all times. That is why you will not only receive medical care from us, but also clear, understandable instructions for every phase of penis enlargement.
Before the penis enlargement operation
- Take your time to make your decision - we will advise you without pressure.
- Our special feature: patients can cancel their penis enlargement operation up to the last second free of charge. We do not pressure or persuade anyone to undergo surgery.
- Plan your penis enlargement as stress-free as possible: Many patients do not need a vacation, as the procedure is performed on an outpatient basis.
- Avoid alcohol and nicotine from 24 hours before the penis enlargement. You should refrain from taking blood-thinning medication (after consulting your family doctor!) for 10 days before the operation.
- Bring comfortable clothing, ideally with a wide waistband.
- Our secretarial staff will be happy to help you with your travel arrangements and accommodation for your penis enlargement surgery.
After the penis enlargement operation
- Rest on the day of the operation and follow our instructions for wound care after penis enlargement.
- Wear the dressing as recommended and avoid rubbing and pressure on the surgical area.
- You should refrain from sexual intercourse and sporting activities for about five weeks after penis enlargement - after that you will usually be able to exercise again without restrictions.
- Showering is usually possible again a few days after penis enlargement - bathing, saunas and swimming pools should only be used after approval by the doctor.
Speed recovery: why our patients are fit so quickly after penis enlargement

Costs of penis enlargement & financing
Clarity right from the start – without hidden fees.
A high-quality medical service has its price – but with us, you know where you stand right from the start. We focus on fair, transparent pricing for penis enlargement without unexpected additional costs. Because trust begins with openness.
What does penis enlargement cost?
All prices include examination, preliminary consultation, surgery, anesthesia, aftercare and medical care.
As a leading institution, we do not need to play tricks with our price list to attract patients.
-
Combination of penis enlargement & penis thickening in both states:
approx. 10,900 euros
We always recommend the combination to our patients. Because in reality it is the most cost-effective option. Patients who only start with one part are sometimes so enthusiastic that they have a second operation to do the other part. If you start with the thickening, then do the lengthening first and then want to thicken the lengthened part again, this is ultimately the most expensive option.
-
Penis enlargement only:
approx. 7,900 euros -
Penis thickening only:
approx. 6,600 euros
Possible operation locations: Darmstadt (Germany) + Palma de Mallorca (Spain); see under UGRS locations.
-
Special lipografting for augmentation in the flaccid state (length and thickness)
approx. 4,800 euros
This method, which is also scientifically based, was developed for patients who only want optimized augmentation in the flaccid state without restructuring the ligament structures.
Possible operating location: Budapest, Hungary; see under UGRS locations.
Payment options
- Bank transfer
- EC or credit card
- Cash payment (anonymous, possible without notification)
- 0 % installment payment with a 12-month term: In cooperation with our financing providers, we offer you interest-free installment models - flexible and plannable.
Why quality has its price
Our surgical technique for penis enlargement in Darmstadt is based on over two decades of research, development and international exchange. We work exclusively with qualified personnel, high-quality materials and state-of-the-art instruments. All of this goes into the cost of penis enlargement – as well as your safety, satisfaction and lasting results.
Our promise
- No hidden costs for penis enlargement
- No additional fees for aftercare
- No compromise on quality and safety in penis enlargement
If you’re considering penis enlargement, do it right – with a specialized team that doesn’t compromise.
How big is the average penis when erect?
Read our analysis based on scientific facts and publications below.
The European condom standard EN ISO 4074 can clearly be used for the European penis: The standard-compliant condom has a length of at least 16 cm (Citation: 52, 53). As the DIN standard requires condoms to fit snugly so that their protective function can be effective, the average European penis cannot be significantly shorter than 16 cm. Otherwise, all standard-compliant condoms would be too large and would not be able to fulfill their protective function.
A recent study of 4,800 Italian men found that the average Italian penis is 16.78 cm long when erect (Citation: 54). This is roughly in line with the European condom standard.
The average European penis is therefore approx. 16 -17 cm long when erect.
The fact that an average penis is only 14.13 cm or even only 12.3 cm long, as has often been claimed in the past, is simply wrong.
What led to these incorrect values in publications in the past?
Has penis size changed in recent years?
Interestingly, a large-scale study has found that penis size has increased by 24% in the last 20 years (Citation: 55). This is not actually possible because the time span is far too short for a serious evolutionary change.
Of course, not all men have suddenly had a penis enlargement.
Certain measurement methods led to incorrect results
The previous procedure was to determine the penis size in erection by stretching the flaccid penis. One study found that on average the penis is 2.64 cm too small in relation to a real erection (Citation: 56).
In old studies, it was apparently wrongly assumed that the stretched length of the flaccid penis is identical to the erection length.
And they probably didn’t consider that the length of the pulled penis depends on the pulling force of the person examining it.
Why are ethnic differences in penis size important?
In addition, it is likely that the old values referred to the average man worldwide. In the past, it was not taken into account that there are considerable ethnic differences in penis size (Citation: 57, 58, 59).
The old studies on average penis size included Asian men, although Asian men, especially Chinese men, have significantly smaller penises than European or US men (Citation: 59).
This does not mean that Chinese men all need penis enlargement, it just means that there are significant differences.
Conclusion: The studies and publications prior to 2006 and later studies that referred to the old ones obviously overlooked the error-prone measurement method of elongation (which is also dependent on the traction force) and the ethnic differences. They are therefore based on false assumptions.
It can be assumed that penis sizes have not recently increased by 24%, but have always been 24% larger than measured due to the flawed measurement protocol.
What is the scientifically correct procedure?
It is now scientifically recommended to measure average penis sizes in relation to their ethnic variance in order to better address the needs of patients or partners (Citation: 58).
For a European woman who has a problem with her partner’s penis size, it is of no use to be told the average size of a Chinese man’s penis.
Is penis size related to other body characteristics?
According to scientific findings, there is a correlation between the size of the penis in an erect state in terms of length and thickness and body size (Citation: 54).
Curious: According to the latest scientific findings, the connection between nose size and penis size could actually be true (Citation: 60)
Is penis size important?
Based on our decades of evidence-based work, extensive experience and interviews with patients and their partners, we can clearly answer this question with “yes”. Penis enlargement is therefore definitely justified.
What does science say about the importance of penis size?
What science says: There are very few studies and publications from the past. Possible dissatisfaction with the penis size of the partner by the woman was apparently negated.
The question of why an erect penis gets bigger and not just hard was also not investigated. Size must therefore inevitably play a role.
Which current studies confirm the importance of penis size?
Studies confirm that penis size plays a role in women’s choice of partner (Citation: 61, 62).
A study by California State University and the University of California, which analyzed a survey of around 52,000 men and women in partner relationships, confirms that 84% of women are generally satisfied with the size of their partner’s penis, but also reports that 14% of women would like their partner to have a larger penis (Citation: 63).
Why is 14% dissatisfied women a significant number?
14% may not sound like much at first, but in reality it is a lot, making the issue of penis size very important for women and their sexual satisfaction. Because 14% means more than 8 million women in the USA alone and more than 12 million women in Europe. Penis enlargement could increase satisfaction.
How important is penis size compared to other physical desires?
This 14% is also almost as much as the 20% of men who would like their partners to have larger breasts (Citation: 64).
This means that the issue of penis size is much more important for women than previously assumed by society. Even if they have not yet clearly demanded penis enlargement from their partner.
Does the preference for larger penises have an evolutionary advantage?
Scientists have been investigating whether there is an evolutionary reason for women’s preference for larger penises.
The results are impressive:
How has the female body influenced penis size in evolutionary terms?
The female body seems to have had a decisive evolutionary influence on penis size. The penis appears to have increased in size because the human vagina is larger compared to primates, so that the larger head of a human child, which results from the larger brain, can fit through it. In order for the human penis to continue to fill the vagina during sexual intercourse, it inevitably had to become larger (Citation: 65).
Do larger penises increase the probability of reproduction?
Larger penises also appear to increase the probability of reproductive success (Citation: 66).
A larger penis could therefore be important in terms of the probability of reproduction.
This also underlines the importance of penis enlargement from a biological point of view.
What role does the size variance of the vagina play?
Studies confirm a considerable variance in the size of the female vagina (Citation: 67, 68). Consequently, it is probably correct to assume that penis size also plays a role in finding a suitable partner.
Why is female sexual dissatisfaction not addressed by society?
Has emancipation in sexuality been completed?
If penis size is obviously important for reproduction and sexual experience, why is it no longer discussed in society that the large number of 14% of women do not experience sufficient sexual satisfaction from their partner’s penis and would in principle like to see their partner’s penis enlarged?
It seems to be due to the fact that female sexuality is still suppressed by men (Citation: 69, 70, 71).
What increases women's sexual satisfaction?
It was already proven in 1991 that sexual satisfaction and contentment in a woman’s life increases significantly when she dares to express and demand her personal desires (Citation: 72).
Emancipation has not yet been fully achieved.
What should society and science do?
Society and science should make further efforts to promote equal rights for women, including in sexual matters.
Since the penis is a mechanical instrument for obtaining pleasure, we believe that an emancipated woman is also entitled to express dissatisfaction with her partner’s penis. Penis enlargement can improve the mechanical effect.
Are women actively involved in the decision to enlarge their penis?
Who makes appointments for penis enlargement surgery?
Women are becoming active: We can report from our evidence-based medical practice that more and more women are making an appointment for penis enlargement surgery for their partner.
Penis enlargement surgery is not a male issue, as was long assumed, but affects both partners equally.
