Getting your sperm count tested starts with a semen analysis, a straightforward lab test you can get through your primary care doctor, a urologist, or a fertility clinic. The process involves producing a semen sample, either at a clinic or at home, which is then examined under a microscope to measure how many sperm are present, how well they move, and whether they’re shaped normally. A normal sperm count falls between 15 million and 200 million sperm per milliliter of semen.
How to Get the Test Ordered
You don’t need a specialist to get started. Your primary care doctor can order a semen analysis, and most hospital-affiliated labs and fertility clinics perform them routinely. If you’d rather skip the referral step, some fertility clinics accept self-referred patients for standalone semen analyses. The cost varies, but insurance often does not cover it. Expect to pay roughly $100 to $250 out of pocket at most labs, though fertility clinics that bundle additional services may charge more.
Preparing for the Test
The most important preparation step is abstaining from ejaculation for 2 to 3 days before your sample collection. This window gives your body enough time to build up a representative sperm count. Abstaining for less than 48 hours can produce a misleadingly low count, while waiting longer than 3 days can actually impair semen quality, since older sperm begin to break down and affect motility and morphology results.
Beyond abstinence timing, there are a few practical things to keep in mind. Urinate and wash your hands and penis before collecting the sample to keep bacteria out. Don’t use lubricants or saliva, both of which can damage sperm. And if you miss collecting any of the ejaculate, let the lab know rather than trying to recover it, since that could contaminate the sample.
Collecting at the Clinic vs. at Home
Most labs have a private room where you produce a sample by masturbating into a sterile container. It’s not the most comfortable experience, but it’s the most reliable option because the sample goes straight to the microscope.
If producing a sample at the clinic feels too stressful, many providers allow home collection. The traditional rule is to keep the sample at body temperature (tuck it inside your jacket, for instance) and deliver it to the lab within 30 to 60 minutes. Your provider may also give you a special collection condom so you can collect during sex, then transfer the sample to a sterile container for transport.
A newer option is mail-in testing kits that use a preservation solution to stabilize the sample. Research from USC’s Keck Medicine found that semen treated with these preservatives can be accurately tested up to 52 hours after collection, even after exposure to a range of temperatures that mimic shipping across different climates. These kits make testing accessible if you don’t live near a fertility lab.
At-Home Screening Kits
If you want a quick check before committing to a full lab visit, FDA-cleared home testing devices exist. Some are basic and only detect whether sperm are present or absent, which is really only useful if you’re checking after a vasectomy. Others, like smartphone-based kits, attach a small microscope to your phone and measure the concentration of moving sperm in your sample.
These devices are more accurate than you might expect. One study published in Fertility and Sterility found that the Yo home device showed 97.8% accuracy compared to a laboratory-grade analyzer, with strong agreement for samples up to 94 million sperm per milliliter. It reliably distinguished between low and normal concentrations using a cutoff of 6 million motile sperm per milliliter.
The catch is that home kits measure only one or two parameters. A full semen analysis evaluates count, motility (how well sperm swim), morphology (whether sperm are shaped normally), semen volume, and pH. A home kit might tell you your count looks fine while missing that your motility or morphology is abnormal. Think of home kits as a screening tool, not a replacement for the full picture.
What the Results Mean
A standard semen analysis report covers several values, but sperm concentration is the number most people focus on first. Here’s how the thresholds break down:
- Normal: 15 million to over 200 million sperm per milliliter
- Low (oligospermia): fewer than 15 million sperm per milliliter
- Severely low: fewer than 5 million sperm per milliliter
- Absent (azoospermia): no sperm detected at all
A low count on a single test doesn’t necessarily mean you have a fertility problem. Sperm production fluctuates based on stress, illness, medications, alcohol use, weight changes, and even recent fevers. That’s why doctors almost always order a repeat test before drawing conclusions.
Why You’ll Likely Need a Second Test
Sperm counts can vary significantly from one sample to the next. A single semen analysis is a snapshot, not a definitive verdict. The traditional recommendation has been to wait at least four weeks before repeating the test, but more recent data suggests the ideal timing depends on which parameter came back abnormal.
Research published in Fertility and Sterility found that sperm concentration correlates most strongly when retested within the first one to two weeks, while motility results are most consistent when retested at around 10 to 13 weeks. If you’ve recently made lifestyle changes (lost weight, stopped a medication, cut back on drinking), waiting two months or more before retesting gives your body time to produce a new cycle of sperm, since sperm take about 72 days to fully develop.
Your doctor will typically recommend the repeat timing based on your specific results and any recent changes in your health or habits.
What Happens After an Abnormal Result
If two semen analyses confirm a low count or poor motility, the next step is usually a visit with a urologist or reproductive endocrinologist. They’ll look for treatable causes: hormone imbalances, varicoceles (enlarged veins in the scrotum that raise testicular temperature), infections, or medication side effects. Blood work to check testosterone and other hormone levels is common at this stage.
Many causes of low sperm count are reversible. Varicocele repair, hormone therapy, stopping offending medications, and lifestyle changes like reducing alcohol intake or losing weight can all improve counts over the course of a few months. For cases where counts remain very low or sperm are absent entirely, assisted reproduction techniques are often still an option.
