A semen analysis is the objective starting point when pregnancy isn’t happening. The standardized assessment shows whether sperm concentration, movement, and shape are sufficient for fertilization. Here’s a practical overview: realistic costs, the current WHO standard, clear prep steps, and evidence-based measures that can improve semen quality.

What is a semen analysis (spermiogram)?

It’s a laboratory test to assess male fertility. Typical measures include:

  • Ejaculate volume (mL)
  • Sperm concentration (million/mL) and total count per ejaculate
  • Motility (total and progressive)
  • Morphology (percentage of normally shaped sperm)
  • Vitality (living sperm)
  • pH and leukocytes as an inflammation indicator

Parameters are measured using internationally accepted protocols and are always interpreted in clinical context (history, course over time, associated findings).

When is a semen analysis appropriate?

Workup is recommended after 12 months of regular unprotected intercourse without pregnancy. Earlier testing is sensible with risk factors (e.g., varicocele, undescended testis, after chemo-/radiotherapy). For a structured work-up, see the EAU guideline on male infertility.

  • Primary or secondary infertility
  • Abnormal hormones or pubertal disorders
  • Pre-/post-vasectomy checks
  • Recurrent miscarriage
  • Pelvic surgery or radiotherapy

Semen analysis – cost & coverage

Typical in the United States: about $100–200 per test at private labs. With a clinical indication, health insurance may cover testing when ordered by a clinician; coverage varies by plan and network. Fertility centers often offer packages including a repeat test. Important: results fluctuate — plan a repeat after ~ 6 weeks to smooth natural variation and measurement error.

Semen analysis: process & preparation

Preparation

  • 3–5 days of abstinence (for comparability)
  • No fever or acute infections; avoid prolonged sauna sessions
  • Minimize alcohol and nicotine; ensure sleep and stress reduction

Sample collection

  • Wash hands and penis with water and soap
  • No lubricant or condom with additives
  • Collect the entire ejaculate in a sterile container
  • If collected at home, keep at body temperature (~ 98.6 °F / 37 °C) and deliver within 60 minutes to the lab

In the lab, standardized measurements (microscopic/digital) are performed per the WHO manual.

WHO reference values (6th edition, 2021)

The WHO reference lists, among others, these thresholds:

  • Volume: ≥ 1.5 mL
  • Concentration: ≥ 15 million/mL
  • Total count: ≥ 39 million per ejaculate
  • Total motility: ≥ 40%
  • Progressive motility: ≥ 32%
  • Morphology (normal forms): ≥ 4%
  • Vitality: ≥ 58%
  • pH: ≥ 7.2

Values below these thresholds don’t automatically mean infertility, but they do warrant medical interpretation and follow-up.

Laboratory quality: what to look for

  • Accreditation (e.g., DIN EN ISO 15189)
  • Regular external quality assurance/ring trials
  • Strict WHO protocols, documented SOPs
  • Double reading or a quality-assured second review

Helpful patient information on diagnosis and treatment: the NHS and the UK regulator HFEA provide accessible overviews; evidence-based guidance is available from NICE.

Turnaround & report

The analysis usually takes 60–120 minutes. A written report is often available within 2–4 business days — commonly via a secure online portal followed by a clinical discussion.

Interpretation: what do deviations mean?

  • Oligozoospermia — low concentration
  • Asthenozoospermia — reduced motility
  • Teratozoospermia — abnormal morphology
  • Cryptozoospermia — extremely low concentration
  • Azoospermia — no sperm detected

To account for natural fluctuation, a repeat after ~ 6 weeks is usually advised — same preparation and conditions.

Common causes

  • Hormonal disorders (testosterone, FSH, LH, prolactin)
  • Genetics (e.g., Klinefelter syndrome, Y microdeletions)
  • Infection/inflammation (e.g., chlamydia, mumps orchitis)
  • Lifestyle (smoking, alcohol, obesity, chronic stress)
  • Heat/environment (tight clothing, sauna, pesticides, plasticizers, microplastics)
  • Temporary factors: fever, certain medicines

Structured assessment includes history, exam, hormones and, if indicated, genetics — see EAU Male Infertility.

Practical tips: improve semen quality

  • Stop smoking and reduce alcohol
  • Normalize weight (even 5–10% loss can help)
  • Regular, moderate exercise; avoid overheating
  • Stress management (breathing exercises, sleep hygiene, realistic workload)
  • Diet rich in fruit/veg, omega-3s and zinc; cut highly processed foods
  • Supplements with care (e.g., CoQ10, L-carnitine) after medical advice

Realistic timeline: improvements often need at least 3 months — roughly one spermatogenesis cycle.

Patient-friendly overviews: NHS treatment; evidence-based guidance: NICE CG156.

When to see a doctor

  • No pregnancy after 12 months of regular unprotected intercourse
  • Abnormal first result or azoospermia
  • Risk factors: varicocele, undescended testis, chemo-/radiotherapy
  • Pain, swelling, or signs of infection

Guideline-based assessment and treatment are summarized in the EAU guideline.

Myths & facts

  • Myth: “One semen analysis is always enough.” — Fact: Values fluctuate; repeating after ~ 6 weeks improves reliability.
  • Myth: “A hot bath or sauna improves quality.” — Fact: Heat often lowers motility; cooler, breathable clothing is preferable.
  • Myth: “More exercise equals more fertility.” — Fact: Moderate activity helps; over-training and heat may harm.
  • Myth: “Supplements solve everything.” — Fact: CoQ10, L-carnitine etc. may support, but don’t replace cause-finding and lifestyle change.
  • Myth: “The longer the abstinence, the better the result.” — Fact: Usually best is 2–5 days; very long gaps can reduce motility and vitality.
  • Myth: “Tight underwear doesn’t matter.” — Fact: It raises testicular temperature; loose boxer shorts are often better.
  • Myth: “A normal semen analysis guarantees pregnancy.” — Fact: It’s a snapshot; fertility also depends on timing and female factors.
  • Myth: “Morphology must be over 14%.” — Fact: Current WHO references use ≥ 4% normal forms; older cut-offs can mislead.
  • Myth: “Bad values stay forever.” — Fact: After infections, fever, or lifestyle changes, parameters often improve within ~ 3 months.
  • Myth: “Laptop on your lap is fine.” — Fact: Direct heat sources raise testicular temperature and may impair quality.
  • Myth: “Caffeine/boosters give an instant lift.” — Fact: Moderate intake is usually fine; high doses, energy drinks, and sleep loss are counterproductive.
  • Myth: “Varicocele always needs surgery.” — Fact: Surgery can help in selected cases; decisions are individual and guideline-based.
  • Myth: “COVID-19 causes permanent infertility.” — Fact: Temporary worsening can occur; values often normalize over months.
  • Myth: “DNA fragmentation testing is necessary for everyone.” — Fact: It’s an add-on for specific scenarios (e.g., recurrent miscarriage), not a routine for all.

Summary

A semen analysis provides a clear status check. WHO references set the frame, but the decisive factor is the overall clinical view with trend, history, and partner assessment. Many factors are modifiable — with realistic expectations, focused lifestyle optimization and, if needed, modern reproductive medicine. You’ll go into your consultation well prepared.

Frequently Asked Questions (FAQ)

A semen analysis is a lab test that measures sperm count, motility, morphology, volume, vitality, pH and white blood cell levels to assess male fertility.

After 12 months of unprotected intercourse without conception, or sooner if you have risk factors like varicocele, testicular injury, chemotherapy or radiation.

Through masturbation into a sterile container at the clinic or at home. Wash with water only, avoid lubricants or oil-coated condoms, keep the sample near body temperature and deliver it to the lab within 60 minutes.

Abstain from ejaculation for 3–5 days, avoid alcohol/tobacco for 48 hours, skip saunas or fevers, get plenty of sleep and reduce stress.

In the U.S., expect $60–$150. Many insurance plans cover it under infertility diagnostics; confirm with your provider.

Microscopy takes 60–120 minutes. Full results are available in 2–4 business days, often via secure portal, followed by your doctor’s review.

≥1.5 mL volume; ≥15 million/mL; ≥39 million total; ≥40% motility; ≥32% progressive motility; ≥4% normal morphology; ≥58% vitality; pH ≥7.2.

Low values are categorized as oligozoospermia (count), asthenozoospermia (motility), teratozoospermia (shape), cryptozoospermia (very low count) or azoospermia (no sperm). Repeat testing in six weeks is advised.

Choose CAP- or ISO-accredited labs that take part in external proficiency testing and have two technicians evaluate samples independently.

Generally, two analyses about six weeks apart to account for natural variations.

Hormones (testosterone, FSH, LH), genetics (e.g., Klinefelter), infections (chlamydia, mumps), lifestyle (smoking, alcohol, obesity, stress), environmental toxins (heat, pesticides, plastics), fever or meds.

Chronic stress disrupts hormonal balance and can impair count, motility and morphology. Techniques like meditation and yoga help.

Antioxidants (vitamins C, E, zinc), omega-3 and coenzyme Q10 may improve parameters, but consult your doctor—results vary by individual.

Eat a diet rich in fruits and vegetables, exercise moderately, avoid toxins, manage stress, wear loose underwear and keep testes cool.

Additional testing: hormone panels, genetic assays, ultrasound, DNA fragmentation or surgical sperm retrieval (TESE/MESA) if needed.

IVF mixes sperm and egg in culture. ICSI injects one sperm directly into the egg—used when sperm counts or motility are very low.

Insurance typically covers basic fertility diagnostics. Additional genetic or surgical procedures may require co-pays.

Urology clinics, fertility centers and specialized labs offer semen analyses. Verify their accreditation and experience.

A normal analysis rules out most male factors but does not guarantee conception. A full evaluation of both partners is recommended.

Certain antibiotics, chemotherapy drugs and steroids can temporarily impair sperm. Disclose all medications to your provider beforehand.
