You've just received your semen analysis report. You're looking at a page of numbers — count, motility, morphology, volume — and you don't know what any of it means. The clinic told you it was "borderline" or "not great" and moved on.

Here's what each parameter means, what the current WHO reference values actually say, what the numbers are trying to tell you, and what to do next.

What Is a Semen Analysis?

A semen analysis (also called a seminogram or spermogram) is a laboratory test that evaluates the quantity and quality of a man's sperm. It is the foundational test for male fertility evaluation.

What it measures:

  • How much semen is produced (volume)
  • How many sperm are present (count/concentration)
  • How well they move (motility)
  • What shape they are (morphology)
  • Various physical and chemical properties of the semen

What it does NOT measure:

  • Sperm DNA integrity (a separate test)
  • Ability to fertilise an egg (functional testing is separate)
  • The cause of any abnormality

Cost in India: ₹800–₹2,000 at reputable andrology labs. Ensure you use a lab with a dedicated andrology department, not a general diagnostic lab — sample handling and timing of analysis significantly affect results.

How to Prepare for a Semen Analysis

Proper preparation is essential for an accurate result:

Factor: Abstinence · Guidance: 2–5 days before collection · Why It Matters: Too short = lower count; too long = poor motility and quality

Factor: Collection · Guidance: By masturbation into a sterile container · Why It Matters: No condoms (spermicide); no lubricants (toxic to sperm)

Factor: Delivery to lab · Guidance: Within 60 minutes · Why It Matters: Motility degrades rapidly at room temperature

Factor: Temperature · Guidance: Keep at body temperature (37°C) during transport · Why It Matters: Don't refrigerate; don't leave in cold car

Factor: Completeness · Guidance: Collect the full sample · Why It Matters: The first fraction is sperm-rich; losing part of the sample affects count

Factor: Illness and fever · Guidance: Wait 6–8 weeks after any fever before testing · Why It Matters: Fever suppresses sperm production for 2–3 months

Factor: Medications · Guidance: Tell the lab and your doctor what you take · Why It Matters: Some medications affect results

WHO 2021 Reference Values: The Current Standard

The World Health Organisation updated its semen analysis reference values in 2021 (6th edition). These are the values used by reputable fertility labs and clinics.

Important note: These are lower reference limits — the 5th percentile of fertile men. Values below these thresholds indicate likely subfertility. Values at or above these limits do not guarantee fertility — they simply fall within the normal population range.

Parameter: Semen volume · WHO 2021 Lower Reference Limit: 1.4 mL · What It Means: Less than this suggests ejaculatory duct obstruction or incomplete collection

Parameter: Total sperm count · WHO 2021 Lower Reference Limit: 39 million per ejaculate · What It Means: Total number of sperm in the sample

Parameter: Sperm concentration · WHO 2021 Lower Reference Limit: 16 million/mL · What It Means: Number of sperm per millilitre of semen

Parameter: Total motility (PR + NP) · WHO 2021 Lower Reference Limit: 42% · What It Means: Percentage of sperm that move (any direction)

Parameter: Progressive motility (PR) · WHO 2021 Lower Reference Limit: 30% · What It Means: Percentage of sperm moving forward in a straight line

Parameter: Vitality (live sperm) · WHO 2021 Lower Reference Limit: 54% · What It Means: Percentage of sperm that are alive

Parameter: Normal morphology (Kruger) · WHO 2021 Lower Reference Limit: 4% · What It Means: Percentage with normal shape

Parameter: pH · WHO 2021 Lower Reference Limit: 7.2 or above · What It Means: Acidity of semen

Parameter: Liquefaction time · WHO 2021 Lower Reference Limit: Within 60 minutes · What It Means: Semen should liquefy from gel to liquid after ejaculation

Older reports may use WHO 2010 values, which were slightly different. Key differences: WHO 2010 used a lower limit of 1.5 mL for volume (vs 1.4 mL in 2021), 15 million/mL for concentration (vs 16 million/mL), and 40% total motility (vs 42%). Morphology threshold (4% normal forms) remains the same. If your report is from before 2022–2023, ask whether it used current WHO 2021 reference ranges. WHO 2010 vs 2021 key differences at a glance: Volume lower limit: 1.5 mL (2010) → 1.4 mL (2021). Concentration lower limit: 15 million/mL (2010) → 16 million/mL (2021). Total motility lower limit: 40% (2010) → 42% (2021). Normal morphology: 4% (unchanged in both editions).

Understanding Each Parameter

1. Semen Volume

Normal: ≥1.4 mL (WHO 2021)

This is the total volume of the ejaculate. Normal is typically 1.4–5 mL (WHO 2021). Some older references cite 1.5 mL as the lower limit — that was the WHO 2010 threshold.

Low volume (hypospermia, <1.4 mL) may indicate:

  • Incomplete collection (most common — check if the full sample was collected)
  • Retrograde ejaculation (sperm going into the bladder instead of out — check post-ejaculate urine)
  • Ejaculatory duct obstruction
  • Androgen deficiency

High volume (>6 mL) may indicate: Inflammation of the accessory glands (prostatitis, seminal vesiculitis). High volume dilutes the sperm, lowering concentration.

If low volume is confirmed on repeat testing, urine analysis after ejaculation (post-ejaculate urinalysis) is done to check for retrograde ejaculation.

2. Sperm Concentration

Normal: ≥16 million/mL (WHO 2021)

This is the number of sperm per millilitre of semen. The clinical terms:

Term: Normozoospermia · What It Means: Normal sperm concentration · Count: ≥16 million/mL

Term: Oligozoospermia · What It Means: Low sperm count · Count: <16 million/mL

Term: Severe oligozoospermia · What It Means: Very low count · Count: <5 million/mL

Term: Cryptozoospermia · What It Means: Extremely rare, found only after centrifugation · Count: <0.1 million/mL

Term: Azoospermia · What It Means: No sperm in the ejaculate · Count: 0

Mild-to-moderate oligozoospermia (5–16 million/mL) may respond to lifestyle changes or medical treatment. IVF with ICSI is typically recommended.

Severe oligozoospermia (<5 million/mL) requires genetic testing before IVF. ICSI is standard. Surgical retrieval is not usually needed if even a few million sperm are present.

Azoospermia (no sperm) is covered separately — see our article on Male Infertility and IVF.

3. Total Sperm Count

Normal: ≥39 million per ejaculate

Total count = concentration × volume. A man with 20 million/mL and 2 mL volume has a total count of 40 million — adequate. A man with 20 million/mL and 1 mL has only 20 million total.

Total count is often more meaningful than concentration alone, which is why both are reported.

4. Progressive Motility (PR)

Normal: ≥30% progressive motility (WHO 2021)

This is the percentage of sperm moving forward in a straight or curved line at a reasonable speed. This is the number that matters most for natural conception — sperm need to swim upstream through the female reproductive tract.

Types of sperm movement:

  • PR (Progressive): Moving forward — what you want
  • NP (Non-Progressive): Moving in circles or barely moving — counts as "motile" but not useful for natural conception
  • IM (Immotile): Not moving at all

Clinical terms:

Term: Asthenozoospermia · What It Means: <30% progressive motility

Term: Severe asthenozoospermia · What It Means: Very low progressive motility, often <10%

Term: Necrozoospermia · What It Means: Most sperm are dead (high immotile + low vitality)

What improves motility? Correct abstinence period, antioxidants, stopping smoking, and treating underlying infection or varicocele. Some improvement from lifestyle changes, but severe asthenozoospermia usually needs IVF + ICSI.

5. Total Motility (PR + NP)

Normal: ≥42% (WHO 2021)

Total motility includes both progressive and non-progressive sperm. It is less clinically important than progressive motility alone, but is reported in all analyses.

6. Sperm Morphology

Normal: ≥4% normal forms (WHO 2021, Kruger strict criteria)

This is the most misunderstood parameter. The "4%" threshold sounds alarming — it means 96% of sperm are considered "abnormal" in shape, and the sample is still considered normal.

This is because sperm shape is naturally highly variable. Even in fertile men, most sperm have minor structural abnormalities. The Kruger strict criteria (used by most accredited labs) is very precise — a sperm must have a perfect oval head, intact midpiece, and straight tail to be counted as "normal."

What abnormal morphology looks like:

Defect: Large head / small head · Description: Head too big or too small

Defect: Tapered head · Description: Elongated, pointed head

Defect: Coiled tail · Description: Tail wrapped around head or midpiece

Defect: Double head or double tail · Description: Two heads or tails

Defect: Cytoplasmic droplets · Description: Excess cytoplasm — indicates immature sperm

Defect: Amorphous · Description: Irregular, unclassifiable shape

Clinical terms:

Term: Teratozoospermia · Meaning: <4% normal morphology

Term: Severe teratozoospermia · Meaning: <1% normal morphology

Term: Globozoospermia · Meaning: Round-headed sperm with no acrosome — rare but specific

What morphology means for IVF: In natural conception, morphology matters significantly — sperm with abnormal shapes struggle to penetrate the egg. In IVF with ICSI, the embryologist selects the best-looking individual sperm under high magnification — poor morphology affects ICSI less than natural conception or conventional IVF. Even with severe teratozoospermia, ICSI can achieve reasonable fertilisation rates.

7. Sperm Vitality

Normal: ≥54% live sperm (WHO 2021)

Vitality measures the percentage of sperm that are alive, using dye exclusion tests (live sperm exclude the dye; dead sperm absorb it).

Vitality is especially important when motility is very low. If motility is low but vitality is high, the sperm are alive but not swimming well — this pattern suggests a structural motility defect (possibly primary cilia dyskinesia). If both motility and vitality are low, most sperm are dead — a different and more serious finding.

8. pH

Normal: ≥7.2

Semen is naturally alkaline (basic) to protect sperm from the acidic vaginal environment. A pH below 7.0 is associated with ejaculatory duct obstruction or incomplete sample (missing the seminal vesicle fraction).

9. Liquefaction Time

Normal: Within 60 minutes of collection (most samples liquefy in 15–30 minutes)

Fresh semen is gel-like. It should liquefy into a liquid consistency within 60 minutes, allowing sperm to swim freely. Failure to liquefy (or very delayed liquefaction) is associated with male accessory gland inflammation and may impair sperm function.

10. White Blood Cells (Leukocytospermia)

Normal: <1 million WBC/mL

More than 1 million white blood cells per mL of semen suggests infection or inflammation of the genital tract (prostatitis, epididymitis). This should be investigated and treated before proceeding with fertility treatment.

Common Semen Analysis Terminology

Report Says: Normozoospermia · Plain Language: Everything normal · What To Do: No male factor concern — if infertile, investigate female factors and timing

Report Says: Oligozoospermia · Plain Language: Low count · What To Do: Lifestyle changes, andrologist referral; ICSI likely needed

Report Says: Asthenozoospermia · Plain Language: Low motility · What To Do: Lifestyle changes, check for infection/varicocele; ICSI for IVF

Report Says: Teratozoospermia · Plain Language: Poor morphology · What To Do: ICSI significantly improves fertilisation; less impactful on ICSI outcome

Report Says: OAT syndrome · Plain Language: Oligo-Astheno-Teratozoospermia — all three abnormal · What To Do: Common combined finding; comprehensive workup and ICSI

Report Says: Azoospermia · Plain Language: No sperm · What To Do: Full workup; surgical retrieval evaluation

Report Says: Hypospermia · Plain Language: Low volume · What To Do: Check for retrograde ejaculation, obstruction

Report Says: Leukocytospermia · Plain Language: Infection/inflammation · What To Do: Treat before IVF

What the Report Doesn't Tell You

A semen analysis captures a snapshot of sperm on one day. It does not measure:

Sperm DNA fragmentation: The integrity of the genetic material inside the sperm. High DNA fragmentation can cause failed fertilisation, poor embryo development, and miscarriage — even when conventional parameters (count, motility, morphology) look normal. Recommended after unexplained IVF failure or recurrent miscarriage.

Acrosome reaction: Whether sperm can undergo the chemical change needed to penetrate the egg. Tested in specialised andrology labs, rarely done routinely.

Sperm function tests: Zona binding, hamster egg penetration. Rarely used in clinical practice.

Common Misconceptions About Semen Analysis

"My count is 30 million/mL — that's fine, right?" 30 million/mL is above the WHO threshold of 16 million/mL. But if motility is poor (say, 15% progressive), the number of functional sperm is much lower. All parameters together tell the story.

"The report says 'slightly reduced morphology' — it's probably fine." "Slightly reduced" often means 2–3% normal forms — below WHO threshold. This is clinically significant, especially for natural conception or conventional IVF. It matters less for ICSI.

"A normal semen analysis means I'm fertile." A normal semen analysis means sperm parameters are within reference ranges. It doesn't rule out DNA fragmentation, functional defects, or other factors. About 15% of infertile men have a normal basic semen analysis.

"Low count is permanent." Often it is not. Sperm production responds to lifestyle changes, treatment of varicocele, and medical therapy in many cases. Retest at 3 months after changes.

"We can't have children if my count is very low." Even men with counts of 0.5–1 million/mL have fathered children through ICSI. Surgical retrieval makes it possible even in azoospermia. The path may be longer, but options exist.

When to Repeat the Test

Always repeat an abnormal semen analysis before making treatment decisions.

Repeat at 4–6 weeks if:

  • Any parameter is below the WHO lower reference limit
  • You had a fever or illness in the 3 months before the test
  • Abstinence was not 2–5 days
  • The sample was not fully collected

Repeat at 3 months if you have made lifestyle changes — smoking cessation, weight loss, supplement use — to evaluate whether improvement has occurred.

When to See an Andrologist

See a urologist-andrologist (not just a fertility specialist) if:

  • Sperm count is severely low (<5 million/mL)
  • Azoospermia is confirmed
  • There is a clinically apparent varicocele
  • There is a history of genital infection, undescended testes, or prior vasectomy
  • Hormonal panel shows abnormalities
  • You are under 40 with newly identified azoospermia (rule out reversible causes)

An andrologist evaluates the cause; a fertility specialist manages the IVF treatment. You may need both.

Questions to Ask Your Doctor After Your Report

- Which of my parameters are below WHO 2021 lower reference limits? - Should I repeat this test — when and where? - Based on these results, do you recommend I see an andrologist? - Is a hormonal panel indicated in my case? - Is sperm DNA fragmentation testing recommended? - Will ICSI be needed if we do IVF? Is that specifically because of my results? - Are there lifestyle changes you recommend that could improve these numbers? - What is the realistic range of improvement I could expect in 3 months?

The Bottom Line

A semen analysis report is not a verdict. It's a starting point.

Parameters that are below WHO thresholds are clinically significant — they need investigation and should guide treatment decisions. But they're not a ceiling. Sperm production responds to the body. Many parameters improve with changes in health, treatment of underlying conditions, or simply repeating the test under better conditions.

And even in the most severe cases — very low counts, very poor motility, azoospermia — IVF with ICSI and surgical retrieval have given biological parenthood to men who once had no path forward.

Understand your numbers. Ask the right questions. And don't draw conclusions from a single test.
