Here’s a question that rarely comes up when men talk about testosterone over dinner: “Do you want kids, now or ever?”
It should be the first one. Not because it’s sentimental, but because it’s the part of the deal that’s hard to undo.
The question nobody asks at the dinner table
The most expensive deal mistakes I’ve seen weren’t the obvious ones. They were the clauses nobody read: the change-of-control provision, the personal guarantee, the term that looked like boilerplate until it wasn’t.
TRT has one of those clauses. Testosterone therapy is everywhere now. Founders talk about it like a productivity tool, and your group chat probably has an opinion. What almost nobody mentions is that it can affect your ability to have children.
So, does TRT affect fertility? It can. That’s not a scare line. It’s in the guidelines urologists use, and it’s the conversation I’d want any clinic to start with.
I’m the founder of The Vitality Collective, not a clinician, so this isn’t medical advice. It’s the question list I’d want in my own hands.
What the guidelines say, plainly
Testosterone you take from outside the body can tell your brain to dial down your own production. That signal also drives sperm production. Turn it down, and sperm production can drop, in some men to very low levels or to none at all.
The American Urological Association’s testosterone guideline is direct about it:
- If you’re currently trying to conceive, testosterone therapy shouldn’t be prescribed. That’s a strong recommendation.
- If you’re interested in fertility, you should have a reproductive-health evaluation before treatment starts.
What does that evaluation involve? The AUA describes a testicular exam and a blood test for follicle-stimulating hormone (FSH), a hormone that reflects how your sperm production is working. Depending on the results, a clinician can add a semen analysis. None of that is exotic. It’s a baseline, the same way you’d want a clean audit before an acquisition rather than after.
Note the wording. It says “can affect,” not “makes you infertile.” Plenty of men on TRT never think about fertility because it isn’t on their roadmap. The point is to decide that on purpose, not find out later.
“Future” fertility counts too
This is the part that catches founders. You might not be trying to conceive this year. Maybe not for five years. You’re still in scope.
The male infertility guideline from the AUA and the American Society for Reproductive Medicine says that for a man interested in current or future fertility, clinicians shouldn’t prescribe testosterone therapy.
And the AUA testosterone guideline says the long-term impact on sperm production should be discussed with any patient interested in future fertility.
What about stopping later? Sperm production comes back for most men after they stop, but not for all, and the timeline varies a lot. It can take months, and in rare cases years, and how much comes back varies too. That’s not a promise in either direction. It’s a variable you’d want priced in before you start, not after.
Why this hits founders and executives
The company comes first. I get it. I’ve lived it.
Family plans get pushed to “after the raise,” “after the exit,” “after things calm down.” Meanwhile you’re optimizing everything you can measure: sleep, training, labs, focus. TRT starts to look like one more lever.
But your family-planning horizon is part of the model too. Maybe your partner has a timeline that isn’t yours. Maybe “never” is a firm answer and maybe it’s just “not now.” Those are different inputs, and they lead to different conversations with a clinician.
A one-to-five-year horizon isn’t a distant hypothetical. That’s the current planning cycle. Nobody builds a five-year plan and leaves out the one variable that can’t be bought back later.
Optimize for the whole timeline
Optimizing today shouldn’t cost you options later. Here’s what a full-timeline plan looks like:
- Your horizon, out loud. Kids now, later, never or undecided. Say it to the clinician in the first conversation, not the fourth.
- Baseline labs, drawn properly. Timing matters with testosterone. I covered the morning-draw issue in Is It Your Hormones or Just Your Thirties?
- A fertility evaluation, if it’s relevant. The AUA recommends it before treatment for men interested in fertility.
- An exit plan. What would stopping look like, and what would you monitor?
One more thing. Forums are full of “fertility protocols” built by strangers. A stranger’s protocol isn’t a plan. Fertility-preserving options are a conversation for a licensed clinician who knows your labs, your goals and your timeline.
Questions to bring to a licensed clinician
Write these down before your appointment:
- Where do my labs actually stand? Not “normal,” the actual numbers, and whether they were drawn at the right time.
- What are my plans for the next one to five years? Answer this one yourself first, and bring your partner into it.
- If I’m symptomatic and want to preserve fertility, what are my options?
- How will we monitor? What gets checked, how often and who’s watching it?
If a clinic can’t answer those clearly, that’s an answer too.
Read the fine print first
This is the conversation I’d want a clinic to start with, not bury in the fine print.
I’ll tell you why I care about this more than most. I started The Vitality Collective after watching my dad go through heart attacks and strokes, and after my mom’s cancer signs were missed. Nobody in that story was a villain. The system just waited until things were loud. I’d rather ask the hard questions while they’re still quiet, and “what does this do to my options later?” is one of them.
TRT can be the right call for the right man. It just works best as a decision you made with the whole timeline on the table.
