Semen Analysis

Normal semen analysis generally shows: volume ≥1.5 mL, pH ≥7.2; sperm concentration ≥15 million/mL; total sperm count ≥39 million per ejaculate; progressive motility ≥32% (total motility ≥40%); vitality ≥58% live; normal morphology (strict criteria) ≥4%; and white cells <1 million/mL. A single abnormal result isn't diagnostic; clinicians usually repeat testing after 2–3 months and assess history and lifestyle.

Best time for a semen analysis is after 2–7 days of sexual abstinence, ideally producing a fresh morning sample. Collect by masturbation into a sterile container at the clinic or at home and deliver within one hour, kept close to body temperature. Avoid recent fever, heavy alcohol, hot baths and certain medications for several days before testing to ensure accurate results.

To read a semen analysis, compare results to reference thresholds: volume ≥1.5 mL; sperm concentration ≥15 million/mL; progressive motility ≥32%; total motile count and morphology (≥4% normal forms); vitality ≥58%; pH ~7.2–8.0; liquefaction <60 minutes; leukocytes <1×10^6/mL; no significant agglutination. Values below these may suggest fertility concerns—repeat testing after 2–3 months and consult a clinician.

Use a validated home semen test kit available online or at pharmacies. Abstain from ejaculation 2–7 days, collect the sample by masturbation into the sterile container provided (don’t use condoms), keep it at body temperature and follow the kit’s timing instructions (usually test within 30–60 minutes). Home tests estimate sperm concentration only; see a clinic for full analysis (motility, morphology) or if results are low or abnormal.

Yes, 70% sperm motility is generally considered very good. Reference ranges put normal total motility around 40%+ and progressive motility near 32%+, so 70% shows strong movement and favorable fertility potential. However, overall fertility depends on other factors (count, morphology, partner factors), so review the full semen analysis and next steps with a healthcare professional if concerned.

A "normal" sperm concentration is generally defined as at least 15 million sperm per milliliter, with a total sperm count per ejaculate of about 39 million or more. Higher counts (for example 50+ million/mL) improve fertility odds. Quality matters too: progressive motility ≥32%, total motility ≥40%, normal morphology ≥4% (strict criteria), semen volume ≥1.5 mL and vitality also affect fertility.
