About to start testosterone and panicking about fertility. Is it too late to freeze anything?

Okay this is the thing nobody at any of my appointments has really pushed me on and now I'm two weeks from probably starting T and it's suddenly all I can think about.

Context: I'm 29, top surgery is the thing I actually want, hormones are the step in front of it. Children were always a "maybe one day, ask me in ten years" question for me, which is exactly why I never sorted it out. But now I'm reading that testosterone can affect fertility and I've spooked myself into thinking I've left it too late and the option is just gone the second I start.

Is that true? Once you're on T is that it? Or can you still do something about it later? I don't even know what "doing something" looks like for someone like me, egg freezing I assume, but I don't know if that means pausing everything for months, or how much it costs, or whether it's even worth it if I'm only 50/50 on kids at all. I hate that I'm making a permanent-feeling decision this fast. Anyone been here?

Been exactly here, so one real data point for you against the panic.

Starting T is not a door slamming. It lowers fertility over time and that part isn't reliably reversible, but it is not the instant off-switch the scary version makes it sound like. What actually ends the option for good is surgery that takes the ovaries out, and top surgery isn't that. So you have more room than 2am is telling you.

I froze eggs before I started, which for me meant a couple of weeks of injections and then a collection done under sedation, home the same day. Was it a fun fortnight? No. Am I glad past me did it even though I'm still only "maybe" on kids? Genuinely yes, because it turned a forever question into a keep-it-in-a-drawer question. You don't have to be sure you want children to want the choice kept open.

Coming at this from the other side of the aisle (trans woman, on the surgical list) but the regret cuts the same direction, so worth saying.

For me it was sperm freezing, and the thing I want you to hear is how quick and undramatic it was compared to the weight I'd put on it. One appointment, no operation, done. What I nearly got wrong was leaving it, telling myself I'd sort it after I felt more settled on hormones, and oestrogen had already been running a while by then so the sample wasn't as good as it would have been earlier. It still worked out, but earlier would have been easier. Whatever you decide, decide it before rather than after.

Elliot, this is such a fair thing to be spinning on, and I want to answer it properly because the panic version and the real version are quite far apart.

The direct answer first: starting testosterone is not the point of no return for your fertility. It reduces it, gradually, and not always reversibly, but the hard permanent line is surgery that removes the ovaries, which is a completely separate decision you are nowhere near. Top surgery does not touch it. So you are deciding early, which is the good position to be in, not the last-chance one.

What it actually depends on: for someone with ovaries the route is egg freezing or embryo freezing, and both start with roughly 10 to 14 days of hormone injections to stimulate the ovaries, then a short egg retrieval under sedation. For trans men that usually means a pause in testosterone and a stretch of oestrogen-driven treatment first, which some people find genuinely hard, so it's fair to name that discomfort to your team up front rather than discover it mid-cycle. Doing it before you start T is easier and more predictable than doing it later, but later is not automatically impossible, so if you started T tomorrow the option would not simply vanish. On cost and funding, that varies a lot by where you are and whether anything is covered, so get that in writing locally rather than trusting a forum number.

The honest limit to hold: freezing keeps a door open, it does not promise a baby. Success later leans heavily on age at freezing and how much is stored. I wrote the whole thing up, the options, the timing, what it does and doesn't guarantee, in fertility preservation before gender-affirming surgery, and where it sits in the run-up is in the pathway, stage by stage. But the real move is one sentence to your team at your next appointment: "I want to talk about fertility before I start." That opens every option that's still open, and it costs you nothing to ask.

This has genuinely talked me down, thank you. Reframing it from "last chance TODAY" to "easier now than later, but not a cliff edge" is exactly what I needed. I've emailed to ask about a fertility referral before my hormone appointment, and I've decided I'd rather do the annoying fortnight and keep the option than gamble on a maybe. Will report back. You're all the reason I stopped catastrophising at 3am.

Just want to add, as someone who did not have this conversation and made her peace with it a different way: there is no wrong answer here, only an informed one and an uninformed one. You're doing the informed one. That's the whole job.
