This is the bet no one at the clinic leads with. TRT works by telling your brain to stop producing and that same off-switch can shut down sperm too. Under 40 especially, men get warned in plain words: "your fear of fertility issues is 100% valid."
Some come off after years and test with next to nothing. Natural production doesn't always come back.
Even if more kids aren't on your radar, nobody wants that decision made for them least of all by a needle. And if fatherhood is still on the table at all, even as a "maybe," that's a door you don't get back once it closes. Primal Sapiens is built to support your own production, never replace it. It refills the tank without telling your brain to switch off. No shutdown. No dependency. No needle. Your engine and your options stay online.
