how it works

Sperm freezing before testosterone replacement therapy

01

Order your collection kit online

Produce your sample at home and ship it back overnight with a prepaid label. We’ll analyze your semen to ensure it’s viable for freezing.

02

We’ll freeze your sample within 48 hours

Once your sample is stored, you can confidently begin TRT, knowing your option to have children in the future is protected.

03

Using your sperm

The more vials you store, the higher the chance that you’ll be able to create a pregnancy. You can keep your samples in storage for as long as you need without affecting their health or viability.

Many people believe that testosterone contributes to fertility, and that testosterone therapy may even improve fertility. However, taking external testosterone can throw off the balance of other reproductive hormones that actually drive sperm production.

As a result, TRT is likely to cause impaired fertility or complete infertility. One study found that 65% of men on TRT become temporarily sterile within 4 months of use.

If you’re not taking actual testosterone, it’s less likely that your medication will negatively affect your sperm production. For example, Clomid (clomiphene citrate) is a medication that has been shown to increase testosterone levels and improve fertility for some men.

If you’re unsure about how your medication will impact fertility, talk to your doctor or schedule a call with one of our fertility advisors.

Possibly. Without getting too technical, hCG mimics the effect of another reproductive hormone, luteinizing hormone (LH). LH is essential to the production of sperm, and LH levels drop significantly for men on TRT. Therefore, taking hCG can help maintain sperm production in those who are taking testosterone. One small study found that hCG helped maintain sperm production for at least a year of TRT.

However, it’s impossible to know how hormone therapy will impact you. Even if you’re taking hCG alongside testosterone, we highly recommend sperm freezing as a back-up plan, especially if you’re certain you want kids in the future.

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 testosterone therapy, 67% of subjects regained a normal sperm count. That means about 1 of every 3 people on testosterone may be unable to recover their fertility.

Not necessarily. It takes time for testosterone replacement therapy to affect your fertility. The quantity and quality of sperm may deteriorate progressively the longer you’ve been taking TRT, and you’ll typically see a significant decrease in fertility or complete sterility after about 4 months of TRT.

If you’re already taking testosterone, 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 TRT for 3–6 months to see if sperm production resumes before continuing with the fertility preservation process.

The chances of conceiving with frozen sperm depend on several factors:

Your sperm quantity and quality

Your partner’s age, egg quantity/quality, and overall fertility health

Whether you use intrauterine insemination (IUI), in vitro fertilization (IVF), or intracytoplasmic sperm injection (ICSI)

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.”

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:

Do you have kids already? If you don’t, there may be a higher chance that you’ll want kids in the future.

How old are you? If you’re in your 20s or 30s, it’s more likely that your family plans may change in the future.

Are you okay with pausing your testosterone replacement therapy in the future to start a family? If you’d rather not, then you may want to freeze more.

Generally speaking, one vial of sperm is used in each IUI or IVF procedure.

1 semen sample = 4 vials of frozen sperm

1 vial of frozen sperm = 1 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.

The process of sperm freezing is very quick with Legacy:

Once you order your kit, it will arrive in as little as 2 days. (You choose your preferred delivery date.)

You should abstain from ejaculation for 2–5 days prior to producing your sample for freezing.

After producing your sample at home, it will be shipped overnight and analyzed and frozen the next day.

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.

As long as sperm is kept frozen in a high quality cryogenic lab like Legacy’s, it can be stored indefinitely with no significant impact on its quality or the chances that it will result in a healthy pregnancy. That means you can keep your sperm frozen until you’re ready to start or grow your family.

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.

1 semen sample = 4 vials of frozen sperm

1 vial of frozen sperm = 1 IUI or IVF procedure

The chances of conceiving with frozen sperm depend on several factors:

Your sperm quantity and quality

Your partner’s age, egg quantity/quality, and overall fertility health

Whether you use intrauterine insemination (IUI), in vitro fertilization (IVF), or intracytoplasmic sperm injection (ICSI)

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.”
