Does TRT Affect Fertility?

Yes — testosterone replacement therapy (TRT) can affect male fertility. Here’s how:

Why TRT Impacts Fertility

• Sperm production is controlled by the brain (pituitary gland + testes connection).
• When a man takes TRT, the body detects high testosterone levels and tells the testes to stop producing their own testosterone.
• This lowers or even shuts down sperm production (spermatogenesis).

Possible Effects

• Reduced sperm count — sometimes to near zero.
• Testicular shrinkage — from decreased activity in the testes
• Infertility — often reversible if TRT is stopped, but recovery can take months to over a year.
• Long-term use — in some cases, can cause permanent fertility issues.

Options for Men Who Want Children

• Some doctors prescribe hCG (human chorionic gonadotropin) or clomiphene citrate alongside TRT to help maintain sperm production.
• Alternatives like selective estrogen receptor modulators (SERMs) may boost natural testosterone without shutting down sperm production.
• If fathering children is a priority, many doctors recommend delaying TRT until after family planning.

TRT can significantly reduce fertility, but with medical guidance, there are ways to preserve sperm production.

If you’re on TRT and want to have children, we can work with you to regain your sperm count and get you back to where you need to be.
