The report arrives as a page of unfamiliar words and numbers: oligozoospermia, progressive motility, morphology, and a few figures marked “low.” For many men, seeing that page feels like being graded. This guide walks through a semen analysis report line by line, in plain language, so you can understand what each result means, what it doesn’t mean, and what to do next.
What a Semen Analysis Measures
A semen analysis is the first and most useful test of male fertility. In a laboratory, a fresh sample is checked for how much semen there is, how many sperm it contains, how well they move, what they look like, and whether they are alive.
Worth Knowing First
A semen analysis is a snapshot of one sample on one day. Sperm numbers and quality vary naturally from sample to sample, and with illness, stress and how long since the last ejaculation. That is why one result is rarely the final word, and why doctors often ask for a repeat. For more on the test’s limits, see how accurate male fertility tests are.
What the Research Points To
Studies that look at overall eating patterns, rather than single "superfoods," suggest that these habits are associated with better fertility and a healthier pregnancy:
| Measurement | What it tells you | WHO lower reference limit |
|---|---|---|
| Volume | The amount of semen in the sample | 1.4 mL or more |
| Sperm concentration | Sperm in each millilitre | 16 million per mL or more |
| Total sperm number | Sperm in the whole sample | 39 million or more |
| Total motility | Share of sperm that move at all | 42% or more |
| Progressive motility | Share that swim forward | 30% or more |
| Vitality | Share of sperm that are alive | 54% or more |
| Normal forms (morphology) | Share with a normal shape, judged by strict criteria | 4% or more |
| pH | How acidic or alkaline the semen is | 7.2 or higher |
Lower reference limits from the WHO laboratory manual (6th edition, 2021). Your lab may use slightly different ranges or an older edition, so always compare your result with the range printed on your own report.
What the Medical Terms Mean
If a value falls below its limit, your report may name it with one of these terms:
Oligozoospermia
A lower-than-reference sperm count. Often shortened to "oligospermia."
Asthenozoospermia
Reduced sperm movement, meaning fewer sperm that move or swim forward.
Teratozoospermia
A lower share of sperm with a normal shape.
Azoospermia
No sperm found in the sample. See our guide to azoospermia.
These can occur together. "Oligoasthenoteratozoospermia" (OAT) simply means count, movement and shape are all below reference. Two other terms you may see are hypospermia (low semen volume) and leukocytospermia (extra white blood cells, which can point to infection; see pyospermia and leukocytospermia).
"Normal" Isn't a Pass or Fail
These limits are statistical. They describe the range seen in men who fathered a child, not a line that separates fertile from infertile. Some men with results below a limit conceive naturally, and some men with every value in range still have difficulty. That is why the numbers are read together, alongside your history and your partner's tests.
Worth remembering:
A low count doesn’t mean zero chance, because it takes only one healthy sperm to fertilise an egg. See why sperm count still matters.
Morphology confuses many men most. A normal-form limit of 4% does not mean 96% of your sperm are "bad." Strict criteria count only perfectly shaped sperm as normal, and most men have a majority of sperm that don't qualify. A low morphology result on its own is rarely the deciding factor.
What Can Change a Result
Before reading too much into a number, consider whether something affected the sample:
- Recent illness or fever. — A fever can lower sperm quality for weeks to months afterwards, because sperm take about three months to develop.
- Time since the last ejaculation. — Too short or too long a gap can shift volume, count and movement. Labs usually ask for a few days of abstinence.
- An incomplete sample, or a delay in delivery. — Missing part of the sample, or letting it cool or sit too long, can distort results. See how to prepare for your semen sample.
- Heat, smoking, alcohol, drugs and steroids, — and some medicines. Read about the habits that matter in how to improve male fertility naturally.
- Stress and poor sleep. — Both can affect semen quality temporarily.
What to Do If Your Result Is Abnormal
- Don't panic, and plan a repeat — Because results vary, doctors usually repeat an abnormal test, often after a few weeks to about three months.
- See a fertility specialist — They will take a history, examine you, and look at your report alongside your partner's results.
- Look for a cause — Further tests may include hormone blood tests, a scrotal ultrasound for a varicocele, a check for infection, a DNA fragmentation test in some cases, and genetic tests where appropriate.
- Treat what can be treated — Many causes are manageable, from infections and varicocele to lifestyle factors. Don't start supplements without advice. See whether sperm count supplements work.
- Match treatment to the result — Depending on severity, options range from timed intercourse and IUI to IVF with ICSI. When no sperm are found in the sample, surgical sperm retrieval may be possible.
Age is also part of the picture for men. See does male age affect fertility too and male infertility symptoms most men ignore.
A Word About the Weight These Numbers Carry
In many families, a low semen result feels like a verdict on a man's masculinity, and some men put off testing for exactly that reason. It is worth saying plainly: a semen analysis measures one body process on one day. It says nothing about strength, character or manhood, and fertility is a shared challenge for a couple, not one person's failure. Getting tested is a step forward for you both.
Common Semen Analysis Myths
| Instead of | Try |
|---|---|
| Taking one abnormal report as proof of infertility. | Repeating the test and discussing it with a specialist. Results vary between samples. |
| Assuming a normal report rules out a male factor. | Knowing that a standard report can miss problems, such as DNA damage, and asking your doctor whether more testing is needed. |
| Reading "4% normal forms" as "96% of my sperm are defective." | Understanding that strict criteria classify most sperm as atypical, even in fertile men. |
| Looking only at the sperm count. | Reading volume, count, movement and shape together, along with your partner's evaluation. |
| Skipping the test, or testing at home and stopping there. | Getting a laboratory semen analysis. Home kits give only a rough idea. See at-home male fertility test kits. |
A semen analysis report is information, not a verdict. Read with a doctor, and alongside the rest of your story, it points to what can be done next.

Frequently Asked Questions
What does a semen analysis report show?
It shows the volume of semen, the sperm concentration and total number, how well the sperm move (motility), what proportion are alive, how many have a normal shape (morphology), and the pH of the sample.
What is a normal sperm count and motility?
The WHO lower reference limits are about 16 million sperm per mL, 39 million in total, and 42% total motility (30% progressive). These are the bottom of the typical range, not a pass mark, and your lab’s range may differ slightly.
What does 4% normal morphology mean?
Four percent is the lower reference limit for sperm with a normal shape under strict criteria. It does not mean the rest are defective, since most men, including fertile men, have mainly atypical forms by these strict standards.
Can semen analysis results change from one test to another?
Yes. Results vary naturally between samples and are affected by illness, fever, stress, how long since the last ejaculation, and sample collection, which is why doctors often repeat an abnormal test.
What should I do if my semen analysis is abnormal?
Don’t panic. Plan a repeat test and see a fertility specialist, who can look for a cause with a history, examination and further tests, and recommend treatment matched to your result.
How should I prepare for a semen analysis?
Follow your lab’s instructions on abstinence, which is usually a few days, collect the whole sample in the container provided, keep it at body temperature, and deliver it promptly. Tell the lab about recent illness, fever or medicines.
