Testosterone replacement therapy, or TRT, is thought by the general public to be a good treatment for infertility in men. But the matter is not that simple. TRT must be undertaken in a more indirect manner in order to be effective.1002

Improper TRT can actually make matters worse. Here we will explain why TRT is a good fertility treatment and how it should be done.

Causes Of Infertility

Fertility issues are a concern for about 15 percent of couples. In half of these cases, the man is infertile. There are various causes, but they all generally fall into one of three categories:

  • Blockages that prevent sperm from being ejaculated
  • Impotence
  • Low sperm count caused by the testes not functioning correctly

As you can see, the causes of infertility in a man can almost always be traced to sperm production or delivery. Treating this problem must, therefore, focus on the sperm or the cause of the man’s inability to ejaculate sperm.

Many treatments are available, but the most effective treatment options that address sperm count usually involve hormone therapy.

Can Low T Treatments Help With Infertility?

Not all testosterone replacement therapies work the same way. Some involve introducing testosterone directly into the man’s body through injections or a patch worn on the skin. But this type of testosterone replacement therapy, or TRT, can actually lower fertility by reducing sperm production.

trt sperm count

This may confuse some people because the common misconception is that high testosterone levels mean high sperm count. This is sometimes true, but there are other factors to consider.

Simply put, the brain uses testosterone as a way to tell the testes to produce sperm. This is why so many people think that direct testosterone replacement cures infertility. But when testosterone is introduced into the bloodstream by artificial means, the brain will stop telling the body to produce its own testosterone. The result is lower testosterone levels and possibly fertility problems.

That being said, hormone therapy is still a valid and effective treatment option for infertility. It just has to be done by a different route. Instead of dumping huge amounts of testosterone into the man’s body, the brain has to command the testes to produce their own testosterone. The most common, safe and effective way to do this is with human chorionic gonadotropin or HCG.

How HCG Treatments Work

This hormone is well-known as a fertility treatment for women. Women use HCG injections to stimulate egg production and induce ovulation. But it is an important factor of male fertility as well.

HCG is not testosterone. It acts like a luteinizing hormone, also known as LH, as it is used by the brain as a signal to the testes to make testosterone. When the body produces its own natural testosterone in this way as opposed to the artificial introduction, there is an actual detectable rise in testosterone levels instead of a drop.

This natural increase in testosterone has been shown to cause the testes to raise sperm count. Of course, higher concentrations of sperm in semen means a higher fertility rate.


In most cases, hormone replacement therapy can cure male infertility, but it is not an open and shut matter that involves TRT by way of injection or other direct introduction. The levels of testosterone must be raised indirectly with HCG-based TRT.

This kind of therapy should be supervised because the manipulation of hormone levels involves many considerations if there is any hope of it being an effective way to increase the chances of conception.

An experienced professional can listen to you, evaluate whether you have other symptoms of testosterone deficiency and decide whether HCG treatment is right for you.
