Testosterone replacement therapy (TRT)
Testosterone replacement therapy, or TRT for short, is a medical treatment in which men are given artificially produced testosterone. This therapy is used when the body no longer produces enough of its own testosterone – a condition known as testosterone deficiency or hypogonadism.
Why is TRT used?
Testosterone is the most important male sex hormone. It influences many physical and mental processes, for example:
- the development of muscles and bones
- the formation of sperm
- sexual desire(libido)
- mood, energy and concentration
If a man produces too little testosterone, this can lead to various complaints, e.g:
- Tiredness and listlessness
- Erectile dysfunction
- Loss of muscle mass
- Mood swings or depressive moods
- Decrease in bone density(osteoporosis)
- Infertility
In such cases, TRT can help to rebalance hormone levels and alleviate symptoms. Before starting TRT, a detailed medical examination is important, including the determination of the testosterone level in the blood.
How is TRT carried out?
Testosterone can be supplied to the body in various ways:
- Gel or cream for application to the skin
- Injections, usually into the muscle
- Patches that slowly release testosterone through the skin
- Tablets or capsules (less common, as less effective)
The therapy takes place over a longer period of time – often months or years – and is regularly monitored by a doctor. Blood values, prostate and other health data are monitored in order to detect side effects at an early stage.
Possible risks and side effects
- Skin changes (e.g. acne)
- Increased hair growth
- Water retention in the body
- Change in cholesterol levels
- Enlargement of the prostate
- Possible restriction of your own sperm production (especially in younger men who want to have children)
TRT is therefore generally only useful if there is a genuine medical testosterone deficiency – and not just to increase performance or build muscle.
