TRT and Fertility: What Men Should Discuss Before Starting Testosterone
Learn why testosterone therapy can suppress sperm production, how fertility goals affect evaluation, and which alternatives require specialist guidance.

For most men, hair loss is one of the worst signs of aging. Once the man starts to go bald, his entire look becomes different and his confidence starts to decrease gradually over time. Many causes can lead to hair loss and baldness and most men ask why hair loss occurs for them in the first place.
Most men tend to ask about their hair loss and whether it is associated with low testosterone levels or not. Does low testosterone levels cause hair loss? The answer is complicated, but the research does show that low testosterone levels are associated with hair loss. Many patients who are interested in starting TRT are also concerned if hair loss is associated with TRT. For related evaluation, see our low testosterone evaluation, TRT guide, and comprehensive hormone symptoms page. Does TRT cause hair loss? In some men, TRT can accelerate hair loss. This is due to the fact that when testosterone combines with an enzyme called 5 alpha reductase it can turn into dihydrotestosterone. In some men, their hair follicles are sensitive to Dihydrotestosterone or DHT and this sensitivity can accelerate hair loss. It is important to note that not all men who undergo TRT will experience hair loss. There are treatments and medications that are available and prescribed by our hormone specialist to combat hair loss while receiving testosterone replacement therapy if that is an issue one is experiencing.
Hair loss is more common in men than women. That is why most men think that testosterone and hair loss are linked. However, this correlation is more complicated than what most men think. Testosterone deficiency can contribute to hair loss. In addition, high testosterone levels can also lead to hair loss. In other words, increasing your testosterone levels will not make your hair grow back or stop balding.

While testosterone deficiency and hair loss are not always related, the correlation between them exists. That is why testosterone replacement therapy is popular among men these days. One of the things that men must put into account is that low testosterone levels affect the hair on the legs, arms, chest, and face in addition to on the top of the head. The other areas are not usually affected the same way as the top of the head. Besides, low testosterone levels are usually associated with other side effects such as fatigue, muscle loss, low sex drive, erectile dysfunction, and depression, which makes the hair loss problem less significant.
Testosterone replacement therapy can help with hair loss caused by low testosterone levels. It helps many men to regain their confidence. Of course, the first step is to check if you have low testosterone levels or not.
