What Is a Semen Analysis?
A semen analysis (also called a spermogram or sperm test) is a laboratory examination of a semen sample that evaluates multiple parameters of sperm health. It is the primary and most cost-effective diagnostic test for male fertility — and typically the very first investigation ordered when a couple is having difficulty conceiving.
The test assesses how many sperm are present, how well they move, what shape they are, and several other characteristics of the semen itself. Results are compared against internationally recognised reference values published by the World Health Organization (WHO), most recently updated in 2021.
📌 Who needs a semen analysis?
- Couples trying to conceive without success for 12 months (or 6 months if the female partner is over 35)
- Men where male factor infertility is suspected — history of mumps, varicocele, undescended testes, or prior groin surgery
- Before IUI, IVF, or ICSI — to assess which treatment protocol is appropriate
- After vasectomy reversal — to confirm successful reconnection
- Men wanting a baseline fertility check before starting a family

Why Is Semen Analysis Important?
Male factor infertility contributes to approximately 40–50% of all infertility cases in couples. Yet historically, fertility investigations focused almost exclusively on women — leaving male causes undiagnosed and untreated for months or years.
A semen analysis changes that. It is inexpensive, non-invasive, and provides actionable information within 24 hours. It is the starting point of the male fertility diagnostic pathway — and often the most important single test in the entire infertility workup.
It Identifies Male Factor — the Most Common Overlooked Cause
Male factor is present in approximately half of infertile couples. A semen analysis immediately identifies whether sperm quantity, movement, or shape is contributing to the difficulty conceiving — information that is essential before choosing any treatment path.
It Is the Cheapest Test With the Highest Diagnostic Yield
At ₹500–₹2,000, semen analysis costs a fraction of female fertility investigations like AMH or HSG. Yet it resolves roughly 40–50% of the diagnostic picture for infertile couples in one step. It should always be done early — not after months of female-only investigations.
It Determines Treatment Direction
Results directly guide what treatment is appropriate. Normal semen analysis with unexplained infertility points toward female-side investigation. Low count may require IUI. Very low count or poor motility indicates IVF + ICSI. Azoospermia triggers a full urological evaluation.
Parameters Can Improve — Testing Enables Monitoring
Unlike female egg reserve, sperm is produced continuously (a new cycle every ~74 days). This means lifestyle interventions — quitting smoking, reducing heat exposure, targeted supplementation — can meaningfully improve results. Testing provides a baseline to measure progress against.
⚠️ A critical mistake to avoid: Many couples spend 6–12 months investigating only female fertility before ordering a semen analysis. This delays diagnosis significantly. The male partner should be tested simultaneously — not sequentially — with the female fertility workup. A semen analysis is fast, cheap, and non-invasive. There is no clinical reason to delay it.
What Does Semen Analysis Measure?
A WHO 2021-compliant semen analysis evaluates seven key parameters. Understanding each one helps you read your report accurately — and have a more informed conversation with your specialist.
Sperm Concentration
The number of sperm cells in each millilitre of semen. This is different from total sperm count (which accounts for the full ejaculate volume). Low concentration is called oligozoospermia; zero sperm is azoospermia.
Total Sperm Count
Concentration multiplied by volume. This represents the total number of sperm available in one ejaculate. It is a more comprehensive measure than concentration alone, as it accounts for semen volume differences.
Motility (Movement)
Measures two types: Progressive motility (sperm that move forward — the most important for natural conception) and Total motility (all sperm showing any movement). Poor motility is called asthenozoospermia.
Morphology (Shape)
Evaluates the structure of sperm heads, midpieces, and tails against strict WHO/Kruger criteria. Most sperm — even in fertile men — are abnormally shaped. Only the percentage with normal form matters. Abnormal morphology is called teratozoospermia.
Semen Volume
The total volume of the ejaculate in millilitres. Very low volume (hypospermia) may indicate a blocked ejaculatory duct or hormonal issue. Very high volume may dilute sperm concentration. Volume must be read alongside concentration.
pH Level
Semen should be slightly alkaline (pH ≥7.2) to protect sperm from the acidic vaginal environment. A very low pH (acidic) may indicate blocked seminal vesicles or absent vas deferens. A very high pH may suggest infection.
Vitality (Sperm Viability)
Measures the percentage of live sperm in the sample. Distinct from motility — sperm can be alive but immotile (not moving). Important when motility is very low. Staining techniques (eosin-nigrosine) are used to differentiate live from dead sperm. Low vitality is called necrozoospermia.
WHO 2021 Normal Reference Values
The following values are the lower reference limits from the WHO Laboratory Manual for the Examination and Processing of Human Semen, 6th Edition (2021). A result below any of these thresholds does not mean infertility — it indicates a possible factor that warrants further evaluation.
| Parameter | WHO 2021 Lower Limit | Below Limit Called | Why It Matters |
|---|---|---|---|
| Semen Volume | ≥ 1.4 mL | Hypospermia | Low volume may dilute sperm or suggest ductal blockage |
| Sperm Concentration | ≥ 16 million/mL | Oligozoospermia | Fewer sperm reduces chances of fertilisation |
| Total Sperm Count | ≥ 39 million/ejaculate | Oligozoospermia | Total sperm available for fertilisation |
| Progressive Motility | ≥ 30% | Asthenozoospermia | Sperm that can swim toward the egg |
| Total Motility | ≥ 42% | Asthenozoospermia | All sperm showing any movement |
| Normal Morphology | ≥ 4% | Teratozoospermia | Kruger strict criteria for normal sperm shape |
| Vitality | ≥ 54% | Necrozoospermia | Percentage of live sperm in the sample |
| pH | ≥ 7.2 | Acidic semen | Protects sperm from vaginal acidity |
* Reference limits from WHO 2021 (6th edition). Values represent the 5th percentile of fertile men. Always interpret alongside clinical history. Lab-specific ranges may differ slightly.
❌ A value below normal does NOT mean infertile
These are lower reference limits — not diagnostic cutoffs for infertility. Men with values below these thresholds have conceived naturally. Men with values above them have been infertile. The report is one input in a clinical picture that includes the female partner's evaluation, relationship history, and other factors. One test result is never sufficient to make a diagnosis.
How Is the Semen Analysis Test Done?
Semen analysis is straightforward. Understanding the process removes uncertainty and helps you produce a valid sample.
Abstinence Period (2–5 Days)
Avoid ejaculation for 2 to 5 days before the test. This ensures an adequate volume and sperm count. Less than 2 days reduces count; more than 5 days may reduce motility and increase DNA fragmentation.
Sample Collection
The sample is produced by masturbation — either in a private room at the lab, or at home if the lab is within 30–60 minutes and the sample is kept at body temperature during transport. Do not use a standard condom (lubricants are spermicidal); use a special collection condom if home collection is preferred.
Delivering the Sample
If collected at home, the sample must reach the lab within 30–60 minutes, kept close to body temperature (wrap the container in a warm cloth). Delays or temperature extremes affect results significantly.
Lab Analysis (30–60 Minutes)
The lab allows the semen to liquefy (takes 15–30 minutes after collection). A laboratory technician then analyses parameters under a microscope using WHO 2021 protocols. Automated sperm analysis (CASA systems) is used at certified fertility labs.
Results
Results are typically available same day or next day. The report lists each parameter alongside WHO 2021 reference values. At least two tests, 2–4 weeks apart, are required before drawing clinical conclusions — sperm parameters fluctuate naturally.
📌 Always use a WHO 2021-compliant lab
Request a report that explicitly states WHO 2021 (6th edition) reference values and uses Kruger strict criteria for morphology. Many general pathology labs still use older WHO 2010 or non-standardised criteria. Fertility clinic labs and certified andrology labs are preferred for accurate morphology assessment.
How to Prepare for Semen Analysis
Simple preparation steps significantly improve the accuracy of your results. Many abnormal reports are produced by avoidable pre-test errors rather than genuine sperm problems.
✅ Do Before the Test
- Maintain 2–5 days of sexual abstinence — the single most important preparation step
- Confirm the lab uses WHO 2021 criteria — ask before booking
- Collect the entire sample — the first portion is richest in sperm; losing any affects results
- Keep the sample warm during transport — close to body temperature (37°C)
- Inform the lab of any recent illness — fever within the last 3 months can suppress sperm parameters temporarily
❌ Avoid Before the Test
- Alcohol — avoid for at least 48–72 hours before collection; heavy use suppresses motility
- Smoking — avoid for as long as possible; nicotine reduces count and motility measurably
- Heat exposure — no hot baths, saunas, or tight underwear in the days before; scrotal heat reduces sperm production
- Lubricants — most commercial lubricants are spermicidal; use only water if needed, or a fertility-safe lubricant
- Medications — inform the lab of any current medications, especially antibiotics, antifungals, steroids, or testosterone products
- Ejaculation within 2 days — reduces count and volume significantly
💡 If you had a fever or illness in the last 3 months: Inform your doctor before testing. High fever temporarily damages sperm production for up to 3 months (the full sperm maturation cycle). Testing too soon after an illness may produce a falsely low result. Waiting 3 months after recovery and retesting gives a more representative picture.
Understanding Your Semen Analysis Results
This is where most guides fail patients. Reading a semen analysis report is not binary — it requires understanding what each finding means clinically, and what it does not mean.
| Diagnosis | Meaning | Severity | Typical Next Step |
|---|---|---|---|
| Oligozoospermia | Low sperm count (<16M/mL) | Mild/Moderate/Severe | Lifestyle changes, IUI, or IVF+ICSI depending on severity |
| Asthenozoospermia | Poor motility (<30% progressive) | Mild/Severe | Antioxidants, lifestyle changes; ICSI if severe |
| Teratozoospermia | Abnormal morphology (<4% normal) | Mild/Severe | ICSI allows selection of best-shaped sperm |
| OAT Syndrome | Low count + poor motility + abnormal shape | Severe | IVF + ICSI; donor sperm if very severe |
| Azoospermia | Zero sperm in ejaculate | Complete | Obstructive: TESA/MESA. Non-obstructive: MicroTESE + ICSI |
| Necrozoospermia | All or most sperm dead (<54% live) | Variable | Investigate cause; repeat test; ICSI with viable sperm |
| Hypospermia | Very low volume (<1.4 mL) | Variable | Rule out retrograde ejaculation, blocked ducts |
Two Critical Rules About Results
⚠️ Rule 1: Always repeat the test
Sperm parameters vary widely between tests due to abstinence duration, illness, stress, heat exposure, and lab variability. WHO recommends at least two analyses, 2–4 weeks apart, before drawing any clinical conclusion. A single abnormal report is never sufficient for diagnosis.
⚠️ Rule 2: One report is not a life sentence
Sperm is regenerated every ~74 days. A poor result today can improve significantly with lifestyle changes, treatment of underlying conditions (varicocele, infection, hormonal imbalance), or targeted supplementation. Retesting after 3 months of lifestyle changes often shows meaningful improvement.
What Happens After Semen Analysis?
Your next step depends entirely on what the results showed. Here are the four main pathways:
Normal Result — Continue Naturally or Investigate Female Side
If semen analysis is normal, male factor is unlikely to be the primary cause. Investigation shifts to the female partner — ovulation assessment, AMH, HSG (tube check), and uterine evaluation. Timed intercourse or IUI may be recommended depending on female findings.
Mildly Abnormal — Lifestyle Changes + Repeat Testing
Mildly low count or motility may respond to lifestyle changes (quit smoking, reduce alcohol, avoid heat, exercise moderately) and targeted supplements (zinc, CoQ10, vitamin C). Retest after 3 months. If improved, continue naturally or with IUI. If unchanged, escalate to treatment.
Moderately Abnormal — IUI or IVF + ICSI
Moderate oligozoospermia or asthenozoospermia may be treated with IUI (if tubes are open) or IVF + ICSI. A reproductive urologist evaluation — hormonal panel (FSH, LH, testosterone), scrotal ultrasound — identifies treatable causes like varicocele or hormonal imbalance.
Severely Abnormal or Azoospermia — Specialist Evaluation
Severe OAT syndrome or azoospermia requires a reproductive urologist. Tests include hormonal panel, genetic karyotyping (Y-microdeletion, CFTR), and scrotal ultrasound. Obstructive azoospermia may be surgically correctable. Non-obstructive requires MicroTESE to retrieve sperm for ICSI.
Causes of Abnormal Semen Analysis
An abnormal result is not random. Most causes are identifiable — and many are treatable. Identifying the underlying cause shapes the treatment approach.
| Cause | How It Affects Sperm | Treatable? |
|---|---|---|
| Varicocele | Dilated veins increase scrotal temperature, reducing count and motility | Yes — surgical repair (varicocelectomy) |
| Hormonal Imbalance | Low FSH, LH, or testosterone suppresses sperm production | Yes — hormonal therapy |
| Infection (STI, epididymitis) | Inflammation damages sperm and blocks ducts | Yes — antibiotics + follow-up |
| Undescended Testes | Abnormal temperature during development reduces production | Partial — surgery helps if early |
| Genetic Factors | Y-chromosome microdeletions, Klinefelter syndrome affect production | Partial — ICSI may still be possible |
| Smoking | Reduces count by ~20%, motility by ~15% | Yes — improves within 3 months of quitting |
| Alcohol | High intake reduces testosterone and sperm production | Yes — improves with reduction |
| Heat Exposure | Hot baths, laptops on lap, tight underwear raise scrotal temp | Yes — lifestyle modification |
| Anabolic Steroids | Suppresses testicular function; can cause azoospermia | Yes — but recovery takes 6–18 months |
| Stress | Cortisol directly reduces sperm production | Yes — stress management |
| Obstruction | Blocked vas deferens or epididymis → azoospermia | Yes — surgical repair or sperm retrieval |
Cost of Semen Analysis in India
Semen analysis is one of the most affordable fertility investigations available. Cost varies by lab type and city — fertility clinic labs charge more but offer more accurate WHO 2021-compliant analysis.
| Lab Type | Typical Cost | WHO 2021 Criteria? | Recommended For |
|---|---|---|---|
| General Pathology Lab | ₹500 – ₹900 | Often uses older criteria | Basic screening only |
| Diagnostic Chain (SRL, Metropolis) | ₹800 – ₹1,500 | Mostly WHO 2010 | Good for count and motility; morphology may be inaccurate |
| Fertility Clinic Lab | ₹1,000 – ₹2,000 | Yes — WHO 2021 + Kruger | Best for complete, accurate analysis before treatment decisions |
💡 Recommendation: For your first semen analysis, choose a fertility clinic lab or certified andrology lab. The additional cost (₹500–₹1,000 more) buys significantly more accurate morphology assessment — which matters enormously when making treatment decisions. Always request a WHO 2021-compliant report explicitly.

FAQs About Semen Analysis
Is semen analysis painful?
No. Semen analysis is completely non-invasive. The sample is collected by masturbation in a private room at the lab or at home. There is no injection, blood draw, or physical examination involved. The only requirement is 2–5 days of sexual abstinence before collection.
Can one abnormal semen analysis confirm infertility?
No. A single abnormal result is never sufficient to diagnose infertility. Sperm parameters fluctuate significantly due to illness, stress, heat, and abstinence duration. WHO recommends at least two analyses 2–4 weeks apart before drawing clinical conclusions. One bad report is not a final verdict.
How many days of abstinence are needed before semen analysis?
WHO recommends 2 to 5 days of sexual abstinence before semen collection. Less than 2 days reduces volume and count; more than 5 days reduces motility and may increase DNA fragmentation. Follow your specific clinic's instructions for best results.
What is a normal sperm count?
Per WHO 2021, normal sperm concentration is 16 million/mL or above, and total count is 39 million or above per ejaculate. Below these thresholds is oligozoospermia (low sperm count). Azoospermia means zero sperm in the sample.
What is normal sperm motility?
WHO 2021 defines normal progressive motility (sperm moving forward) as 30% or above, and total motility as 42% or above. Poor motility is called asthenozoospermia. When severe, ICSI allows fertilisation by injecting a single sperm directly into the egg.
What does abnormal morphology mean for fertility?
Normal morphology (Kruger strict criteria) is 4% or above. Most men — even fertile ones — have a majority of abnormally shaped sperm. Below 4% is teratozoospermia. ICSI lets embryologists select morphologically normal sperm, making fertilisation achievable despite poor morphology.
Can sperm parameters improve with lifestyle changes?
Yes. Sperm takes ~74 days to mature (spermatogenesis). Quitting smoking, reducing alcohol, avoiding scrotal heat, moderate exercise, stress reduction, and supplements like zinc (30mg), CoQ10 (200mg), and vitamin C (500mg) can improve parameters within 3 months.
What happens after an abnormal semen analysis?
A repeat test is done 2–4 weeks later to confirm findings. If still abnormal, a reproductive urologist evaluates the underlying cause — hormonal panel, scrotal ultrasound, and genetic tests if needed. Treatment depends on severity: lifestyle changes, medications, varicocele repair, IUI, IVF, or ICSI.
What is the cost of semen analysis in India?
Semen analysis costs ₹500 to ₹2,000 in India depending on city and lab type. Fertility clinic labs tend to charge ₹1,000–₹2,000 but use WHO 2021 Kruger strict criteria for morphology, which is more accurate than the WHO 2010 standard used at many general labs. Always request a WHO 2021-compliant report.
What is azoospermia and can it be treated?
Azoospermia means zero sperm in the ejaculate. It affects ~10–15% of infertile men. Obstructive azoospermia (blocked ducts) can often be treated surgically or with sperm retrieval (TESA/MESA). Non-obstructive azoospermia (production failure) may respond to MicroTESE surgery. Both types can achieve pregnancy via ICSI with retrieved sperm.
