“The solution that’s being promoted is that we give you testosterone,” he said. “But if you give a man testosterone, you switch off his sperm production. I’ve seen that in the clinic.”

Interesting…

As explained by https://www.nytimes.com/2026/05/12/magazine/testosterone-mas..., "Supplementing with testosterone sends the message to the brain that testosterone is in oversupply, shutting down the testicles’ production of testosterone and sperm... The hormone is so incredibly effective at decreasing sperm counts that it is being tested as a possible male contraceptive."

It's becoming clear that it's not permanent. Discontinuing exogenous testosterone will lead to restarting your own body's production - it just takes a bit, and isn't fun to deal with.

Are you being sarcastic? That has been widely known by steroid users for decades, that's why many of them supplements with hCG in an attempt to preserve their natural production.

		I was diagnosed with Secondary Hypogonadism few years ago. After a series of tests, it was determined that my Testostrone levels well below normal. My urologist prescribed HCG after I insisted that I wanted to have children someday. It has been a life changer and the best part is that my sperm count has doubled. Unfortunately, HCG Mono will not treat all forms of Hypogonadism, some patients have to take Testosterone Cypionate which comes with serious side effects like hair loss, infertility, etc HCG also shares some of those side effects but it saves your fertility and prevents Testicular atrophy.. Also it doesn't shut down your natural production albeit it does suppress LH receptors by default.. My point is this: if you suspect having Testostrone issues, don't randomly inject yourself with hormones.. go see a urologist and get a serious treatment.
