A semen analysis is quick, painless, and the single most important male fertility test. Abstain from ejaculation for 2–5 days before the test. The sample is collected via masturbation into a sterile cup, either at the clinic or at home (if you can deliver it within 60 minutes). Results take 3–7 days. One abnormal result doesn't mean infertility — repeat testing is standard because results vary significantly between samples.
How to Prepare
- Abstain from ejaculation for 2–5 days. Less than 2 days and the sample may have lower volume and concentration. More than 5 days and sperm DNA fragmentation increases (older sperm accumulate damage).
- Avoid alcohol for 3+ days before. Heavy drinking in the preceding days can temporarily reduce sperm quality.
- No hot tubs, saunas, or lap laptops for at least 48 hours before. Heat suppresses sperm production.
- Don't use lubricants during collection — most lubricants kill sperm. If needed, the clinic may provide a fertility-safe option.
The Collection Process
This is the part everyone dreads — and it's honestly the least medically interesting part. You'll be given a sterile collection cup. At the clinic, there's typically a private room with a lock, a chair, and … reading material or a screen. Collect the entire sample in the cup. The whole process takes however long it takes, and nobody is timing you.
If collecting at the clinic feels too stressful, many clinics allow home collection. You'll need to keep the sample at body temperature (carry it in your pocket) and deliver it to the lab within 30–60 minutes. Some clinics provide special collection devices for this purpose.
For partners
If he's anxious about the collection process (many men are), normalize it. This is a routine medical test that millions of men do every year. It takes 15 minutes, and the information it provides is critical — it identifies or rules out male factor in a single test, which can save months of unnecessary testing on the female side.
Reading the Results
| Parameter | Normal Range (WHO 2021) | What It Means |
|---|---|---|
| Volume | 1.4+ mL | Total fluid produced. Low volume might mean incomplete collection or a medical issue. |
| Concentration | 16+ million/mL | How densely packed the sperm are. Below 16M is oligozoospermia. |
| Total motility | 42%+ | Percentage of sperm that are moving at all. |
| Progressive motility | 30%+ | Percentage swimming forward purposefully — the ones that can actually reach the egg. |
| Morphology | 4%+ normal forms | Strict criteria — 4% sounds alarming but is actually normal. |
If results are abnormal: retest in 2–4 weeks. Semen analysis results fluctuate significantly based on illness, stress, heat exposure, and even the collection itself. A single test is a snapshot, not a verdict. Only persistent abnormalities across multiple tests are clinically meaningful.
