Question 211 of 433
Will testosterone affect my fertility?

The short answer
Yes. Testosterone from outside shuts down your own production and can drop your sperm count to zero. Men who want children should not take it.
This is the most common harm I see from casual prescribing in younger men. Recovery after stopping can take many months and is not guaranteed. For men who need treatment and want to preserve fertility, specialists use other drugs, such as clomiphene or hCG, that stimulate the body’s own production instead of replacing it.
