I didn’t have to leave home to understand my fertility. The results came back very quickly, more quickly than I thought. You don’t have to sit there waiting and wondering for too long.
I was about to start testosterone replacement therapy, and realized a week before that I should freeze my sperm in case my fertility doesn’t come back.
My sperm health results were actually great. I decided to freeze because I know I want biological kids one day. I’m 33, and want to be sure all my options are open for when that time comes.

In addition key semen parameters in a Standard Analysis, this testing bundle evaluates DNA fragmentation, a measure of sperm’s genetic health that can help shine a light on infertility, miscarriage, or failed IVF cycles.

Once your kit arrives at the lab, your sample will be opened and labeled. The lab scientists will replenish the sperm transport media to ensure the health of the sperm is maintained during analysis.
Next, the sample will be spun in a piece of lab equipment called a centrifuge to separate the sperm from the semen. Once sperm is concentrated, the lab scientists load a slide containing a portion of the sample into the computer-assisted semen analysis (CASA) system. This will report on sperm count, concentration, and motility (the percentage of sperm that are moving or "swimming"). Sperm morphology, the size and shape of sperm, is evaluated manually by an andrology scientist with a high-powered microscope.
If you choose to complete sperm DNA fragmentation analysis, that's performed using the Halosperm sperm chromatin dispersion technique. In this technique, a small portion of your sample is exposed to chemicals that denature, or separate, the strands of DNA in your sperm. This allows the lab scientists to assess which sperm contain broken or damaged DNA that could contribute to issues getting or staying pregnant.
Legacy’s at-home sperm analysis is a clinic-grade semen analysis without the clinic. It looks at all the key metrics of sperm health, including semen volume, sperm concentration, sperm motility, total motile sperm count, sperm morphology, and sperm DNA fragmentation.
Many at-home sperm testing options don’t look at sperm motility, morphology, or DNA fragmentation, which are important parameters. We’re also the only at-home sperm freezing option that includes a post-thaw analysis, in which we freeze and thaw a small portion of your sample to assess if it’s a good candidate for cryopreservation (sperm freezing).
Basic Semen Analysis looks at count/concentration and motility
Standard Semen Analysis looks at count/concentration, motility, and morphology
Advanced Semen Analysis looks at count/concentration, motility, morphology, and sperm DNA fragmentation
A sperm DNA fragmentation test analyzes what percentage of your sperm have damaged DNA. This damage can contribute to infertility, pregnancy loss, and poor health outcomes for your future children.
Together with a semen analysis, sperm DNA fragmentation testing provides a more complete picture of your reproductive health and your chances of conception.
Sperm DNA fragmentation is measured as part of our Advanced Semen Analysis.
No, we can assess sperm DNA fragmentation as part of the same kit that tests for the standard parameters of sperm health (count, concentration, motility, morphology, and volume).
Legacy’s semen analysis kit has been clinically validated. Our research team has compared the results of our kit to a conventional, in-person semen analysis and found no significant difference. There is likely to be a slight decline in sperm motility when using mail-in kits because of time spent in transit.
Legacy’s kit includes a sperm transport liquid that, when mixed with your semen sample, keeps sperm alive and healthy during shipment to our lab for testing.
From prep to results, it can take less than a week.
As soon as you order your kit, it will be express shipped to you. You should abstain from ejaculating for 2–5 days before using the kit. You should collect and return your sample on the same day, between Monday and Thursday. Each kit includes free overnight shipping back to our lab.
Your results will be available in your online dashboard within 48 hours of our lab receiving your sample. If you choose sperm freezing, your sample will be frozen immediately.
Yes, you can use frozen sperm for intrauterine insemination (IUI), in vitro fertilization (IVF), or intracytoplasmic sperm injection (ICSI). If you’re doing a fertility treatment cycle, having a healthy frozen sperm sample on hand can be an important back-up plan.
