Easily, securely, and affordably preserve your fertility before gender-affirming care with Legacy’s state-of-the-art at-home sperm collection kit.
If you’re considering gender-affirming hormone therapy (GAHT), it’s important to be proactive about fertility. You may not know what your future family will look like — or even if you want kids — but you can take steps to preserve your options.

GAHT, including estrogen and T-blockers may have a significant, long-term impact on fertility. Research finds that certain hormone regimens may impact fertility after just a few weeks.
For that reason, sperm freezing is best done before or at the very beginning of hormone therapy. If you’ve already started hormone therapy, you can test your sperm to see how it’s been affected.
If you have frozen sperm available, you could have a genetic child in the future without stopping your hormone therapy, even if you’ve taken hormone therapy for years or have bottom surgery.
Frozen sperm can be used in IUI (artificial insemination) or IVF later on. Once in storage, sperm remains as healthy and high-quality as it was when you froze it — giving you plenty of flexibility around family-building.
Legacy has helped over 2,000 trans and gender non-conforming patients preserve their fertility.
Legacy is an inclusive option. We partner with leading transgender health clinics, our clinicians are WPATH members, and our team has been trained in transgender care.
We’re 10x faster than a traditional clinic. Freeze your sperm without delaying your gender-affirming care — no doctor’s order required.

You have a lot of other costs to worry about. Here, sperm freezing starts at $245 per year, and we’re in network with most major insurance plans and benefits.
Your kit arrives in discreet packaging, your results are available on a private virtual dashboard, and your sample is stored in multiple locations.
“Do I want kids? I might want them in the future, and this is kind of like insurance. Sperm insurance. Legacy sends you an at-home collection kit, and with that I was able to skip the awkward offices.”

Storing for future family

“I sought out Legacy on really short notice, as I was just about to begin HRT, and I didn't want to take the chance on not being able to have kids in the future. With Legacy, I was able to get my kit in just 2 days, which meant I could start HRT much sooner than if I went with anyone else.”

“I've recommended Legacy to all my friends. Being trans and beginning to medically transition/many of us are met with an influx of hurdles. Legacy made it really easy+accessible. Am super glad opted for Legacy and not a random bank/clinic.”

Yes. We must use your legal name on your contracts and paperwork. However, we’ll ask for — and use — a preferred name during onboarding, on your client dashboard and in all client services communications. We want every client to feel as comfortable as possible during this process.
Yes! Anyone who produces sperm can use Legacy for sperm freezing. At-home sample collection is a more accessible, comfortable, and affordable option for sperm freezing.
Gender-affirming hormone therapy, including estrogen and androgen-blockers (also known as “T-blockers”), is likely to impair or even halt sperm production.
The effect seems to be dose-dependent. In one study, researchers found that low-dose estrogen therapy had no impact on sperm concentration or motility, while a higher-dose regimen resulted in reduced sperm motility after just a few days and reduced sperm concentration after 2 weeks.
Maybe. The “sperm cycle” — how long it takes to produce new sperm — is about 3 months, so you will likely have to pause hormone therapy for at least this long in order to recover fertility. One study found that within 6 months of stopping estrogen therapy, 67% of subjects regained a normal sperm count. That means about 1 of every 3 trans women may be unable to recover their fertility after beginning a medical transition.
We recommend freezing sperm before starting hormone therapy, in order to freeze the highest quality of sperm possible. The higher the quantity and quality of sperm, the more likely it is that you’ll be able to create a pregnancy with that sperm in the future.
However, we know this isn’t always possible, and that in many cases, people will begin hormone therapy prior to exploring fertility preservation. It may still be possible to freeze sperm even after starting GAHT/HRT. We recommend a semen analysis to assess fertility before freezing.
Not necessarily. It takes time for your hormone therapy to affect your fertility. Additionally, hormone therapy affects each person differently. After taking gender-affirming hormones for months or years, you may still produce some sperm. The quantity and quality of sperm may deteriorate progressively the longer you’ve been taking HRT.
If you’re already taking hormone therapy, we recommend starting with a semen analysis. This test will assess the quality of your semen and determine whether your sample is viable for freezing.
If you do a semen analysis with Legacy and have viable sperm, you can upgrade your purchase to include freezing, and freeze that sample immediately.
If you don’t have viable sperm, you can consider pausing your hormone therapy for 3–6 months to see if sperm production resumes before continuing with the fertility preservation process.
Gender-affirming surgery for trans women typically includes orchiectomy, the removal of the testes. Orchiectomy will result in irreversible, total sterility.
If you plan to undergo vaginoplasty, vulvoplasty, or orchiectomy and may want a biological child in the future, we highly recommend freezing at least 3 semen samples to maximize the chances of creating a healthy pregnancy.
Short answer: as many as you can afford. But the ideal number of samples to store also depends on your future plans. A few questions you might consider:
Generally speaking, one vial of sperm is used in each IUI or IVF procedure.
IUI pregnancy rates range from 10–25% per cycle; IVF success rates range from 5–50% per cycle. So, you may need multiple attempts to achieve pregnancy.
Research has found that sperm can essentially be frozen indefinitely as long as it’s preserved at an appropriate temperature. (Legacy uses liquid nitrogen to freeze your sample at -196ºC.) A National Institute of Health study reported that three different samples of frozen sperm had produced healthy pregnancies via assisted reproductive methods after 21, 28, and 40 years of freezing, respectively.
You can use your frozen sperm in an intrauterine insemination (IUI) or in vitro fertilization (IVF) procedure. Generally speaking, one vial of sperm is used in each IUI or IVF procedure.
If you would like to freeze your sample for use with a surrogate or gestational carrier, please reach out. There are strict FDA regulations that must be followed when banking your sperm for surrogacy, and we want to set you up for success.
The chances of conceiving with frozen sperm depend on several factors:
IUI pregnancy rates range from 10–25% per cycle; IVF success rates range from 5–50% per cycle. So, you may need multiple attempts to achieve pregnancy. The good news is that using frozen sperm doesn’t affect your chances of success. IUI and IVF pregnancy rates are the same for those using frozen sperm, compared to “fresh.”
The process of sperm freezing is very quick with Legacy:
In theory, it can take as little as 3 days from start to finish. So, you don’t need to postpone your hormone therapy in order to accomplish your fertility preservation goals.
