Semen Analysis Test: What It Checks, Normal Values & How to Read Your Report

Quick answer

A semen analysis (also called a seminogram) is a simple lab test that examines a man's semen and sperm. It measures how much semen is produced, how many sperm it contains, how well they move (motility) and how normally they are shaped (morphology). It is the first and most important test of male fertility, it is quick and non-invasive, and one abnormal result does not by itself mean infertility - the test is usually repeated to confirm.

Key facts at a glance:

What it checks: volume, sperm count, motility, morphology, vitality and pH.

Preparation: 2-7 days of abstinence before giving the sample.

Normal sperm concentration (WHO 2021): 16 million per mL or more.

Cost in India: roughly Rs 300-1,500 for a basic test.

Repeat: confirm an abnormal result with a second test after about 2-3 months.

What is a semen analysis test?

A semen analysis is a laboratory examination of a semen sample, used to assess the quantity and quality of sperm. Because male factors contribute to roughly 40-50% of infertility cases, this test is recommended for every couple investigating difficulty conceiving, not just the woman. It is inexpensive, painless and gives a fertility specialist a great deal of information from a single sample.

Why is a semen analysis done?

A doctor may recommend a semen analysis when a couple has been trying to conceive for 12 months without success (or 6 months if the female partner is over 35), when there is a known or suspected male fertility concern, before fertility treatments such as IUI, IVF or ICSI, or to check the success of a vasectomy or its reversal. Assessing both partners early avoids months lost to one-sided investigation.

What does a semen analysis check?

A standard semen analysis reports several parameters. Semen volume is the total amount of fluid; low volume can suggest a blockage, retrograde ejaculation or too short an abstinence period. Sperm concentration is the number of sperm per millilitre, and total sperm number is concentration multiplied by volume. Total and progressive motility describe the percentage of sperm that move and the percentage that swim forward effectively. Morphology is the percentage of sperm with a normal shape. Vitality is the percentage of live sperm. The report also notes pH, how the sample liquefies, and white blood cells, which can signal infection.

Semen analysis normal values (WHO 2021)

Most laboratories report results against the World Health Organization reference limits. The WHO 2021 (6th edition) lower reference limits are: semen volume 1.4 mL or more; sperm concentration 16 million per mL or more; total sperm number 39 million per ejaculate or more; total motility 42% or more; progressive motility 30% or more; vitality 54% or more; normal morphology 4% or more; and pH 7.2 or more. Some labs still use the older WHO 2010 limits, so always read your result against the reference range printed on your own report.

How to read your semen analysis report

A report is mostly a list of these parameters with your value beside each reference range. The terms describe how a result differs from normal: normozoospermia means all values are normal; oligozoospermia means a low sperm count; asthenozoospermia means low motility; teratozoospermia means a high proportion of abnormally shaped sperm; oligoasthenoteratozoospermia (OAT) means low count, low motility and poor morphology together; azoospermia means no sperm in the semen; and necrozoospermia means sperm are present but mostly non-viable. A single out-of-range value does not define your fertility, because sperm production runs on a roughly 72-90 day cycle and results vary.

How to prepare for and give the sample

Abstain from ejaculation for 2-7 days before the test, not longer and not shorter. Avoid alcohol and, where possible, recent illness or fever. The sample is given by masturbation into a sterile container, usually in a private room at the lab. If collected at home, keep it at body temperature and deliver it within 30-60 minutes, without lubricants or a regular condom. Tell the lab if any part of the sample is spilled, as this affects the result.

What can cause an abnormal semen analysis?

Many causes are treatable or reversible. Common factors include lifestyle influences such as smoking, excess alcohol, obesity, heat exposure, stress and poor sleep, as well as varicocele, infections, hormonal imbalances, certain medications, and previous surgery or injury.

What happens if your result is abnormal?

The first step is usually to repeat the test after about 2-3 months to confirm the finding. If results remain low, a fertility specialist may suggest further tests such as hormone profiles (FSH, LH, testosterone), a scrotal ultrasound, or a sperm DNA fragmentation test, and a treatment plan. Depending on the cause and severity, options range from lifestyle changes and medical treatment to assisted reproduction such as IUI, IVF or ICSI.

What to do next

A semen analysis is one piece of the fertility picture, alongside the female partner's evaluation. Reading the report together with a specialist, and with calm, unbiased support, prevents fear-driven decisions. Speaking with a counsellor can bring clarity.

Frequently asked questions about semen analysis

What is a normal sperm count?

According to WHO 2021 reference limits, a normal sperm concentration is 16 million per millilitre or more, with a total of at least 39 million sperm in the whole sample. Counts below this are not an automatic diagnosis and should be confirmed with a repeat test.

How many days of abstinence are needed before a semen analysis?

You should avoid ejaculation for 2 to 7 days before giving the sample. A shorter gap can lower the volume and count, while a much longer gap can reduce motility, so staying within this window gives the most reliable result.

How much does a semen analysis cost in India?

A basic semen analysis in India usually costs about Rs 300 to Rs 1,500, depending on the city and laboratory. Advanced tests such as sperm DNA fragmentation cost more. Always confirm the current price and what is included with your chosen lab.

Can a semen analysis be done at home?

The sample can be collected at home, but it must be kept at body temperature and reach the laboratory within 30 to 60 minutes, without lubricants or an ordinary condom. Collection at the lab is preferred because it avoids delays and temperature changes that affect the result.

Does one abnormal semen analysis mean I am infertile?

No. Sperm quality varies naturally and can dip after illness, fever or stress. A single low result is not a diagnosis. Doctors confirm findings by repeating the test after about 2 to 3 months before drawing any conclusion.

What does low sperm motility mean?

Low motility (asthenozoospermia) means fewer sperm are moving or swimming forward effectively, which can make natural conception harder. It is often linked to lifestyle factors, infection or varicocele, and many causes can be improved or treated.

How can I improve my semen analysis results?

Many men improve their results by stopping smoking, limiting alcohol, maintaining a healthy weight, avoiding excess heat, managing stress and sleeping well. Treating an underlying cause such as infection or varicocele also helps. Improvements usually show after one sperm cycle, around 3 months.

Key takeaways

A semen analysis is the first and simplest test of male fertility and checks volume, count, motility and morphology. WHO 2021 normal limits include a concentration of 16 million per mL and 4% normal morphology. Abstain for 2-7 days before the test, and confirm any abnormal result with a repeat after 2-3 months. One low result is not a diagnosis, as sperm quality varies and many causes are treatable. Read your value against the reference range printed on your own report, and review it with a specialist.
