A semen analysis measures count, motility, morphology and volume, and one abnormal report is not a diagnosis because results vary naturally.

Male infertility is involved in around half of all cases, yet the man is often tested last. A semen analysis measures count, motility, morphology and volume, and one abnormal report is not a diagnosis because results vary naturally. Many causes, including varicocele, infection, hormonal problems and lifestyle factors, are treatable.
Most men who walk into a fertility consultation are holding a single sheet of paper with six or seven numbers on it, and no idea which of those numbers actually matter. Some have been told the report is "low" without being told low compared to what. Others have been handed a supplement and sent home.
This page explains what each line on a semen analysis report means, why a single low result is not a verdict, and which underlying causes genuinely respond to treatment. It is written for the man who wants to understand his own report before he decides anything.
A semen analysis measures the quantity and quality of sperm in a single ejaculated sample. The laboratory reports six core parameters, and the World Health Organization publishes a lower reference limit for each one in its laboratory manual for the examination and processing of human semen, sixth edition, published in 2021.
Here is what each parameter is, and the current lower reference limit.
| Parameter | What it measures | WHO 2021 lower reference limit |
|---|---|---|
| Semen volume | How much fluid was produced in the sample | 1.4 ml |
| Sperm concentration | How many sperm are present in each millilitre | 16 million per ml |
| Total sperm number | Concentration multiplied by volume, the total in the whole sample | 39 million per ejaculate |
| Total motility | Percentage of sperm that are moving at all | 42% |
| Progressive motility | Percentage moving forward in a useful direction | 30% |
| Normal morphology | Percentage with a normally shaped head, midpiece and tail | 4% |
| Vitality | Percentage of sperm that are alive, tested when motility is very low | 54% |
Two things about this table surprise almost everyone.
The first is that 4% normal morphology is the reference limit, not 90%. It is biologically normal for the large majority of human sperm to be abnormally shaped. A morphology result of 5% is not a disaster, and a report that flags it in red is using the wrong mental model.
The second is that these are reference limits, not pass marks. They describe the lower end of a population of men whose partners conceived within a year. A man below a limit is not sterile, and a man above every limit is not guaranteed fertile. The numbers shift the odds, they do not decide the outcome.
This distinction is the single most useful thing to understand before you read your own report.
Because a man's semen parameters vary substantially from sample to sample, and a single snapshot can easily land below a reference limit by chance alone.
Several things move the numbers from one week to the next:
This is why the AUA/ASRM guideline on the diagnosis and treatment of infertility in men states that at least two semen analyses obtained a month apart are important to consider, especially where the first showed abnormal parameters.
NHS diagnostic guidance for semen analysis sets the repeat timing by severity. Where the first sample shows apparent azoospermia (no sperm seen) or a severely low total count, the repeat is brought forward to two to four weeks. For other atypical findings, the repeat is done at around three months, because that is roughly how long a new cycle of sperm production takes.
If you have had one low report and nobody has offered you a repeat, that is the next thing to ask for. Treatment decisions made on a single sample are made on incomplete information.
Male infertility is usually traced to one of five groups: a problem with sperm production, a blockage in the pathway out, a hormonal problem driving production, a structural or vascular problem in the scrotum, or a delivery problem at ejaculation.
The NHS list of infertility causes names the common male contributors directly:
Two of these deserve a comment specific to men we see in Surat.
Anabolic steroid use is a common and commonly hidden cause. Steroids taken for physique shut down the body's own hormonal signal to the testes, and the resulting drop in sperm production can be profound. It is also, in many men, reversible once they stop, though recovery takes months and is not guaranteed. If this applies to you, say so at the consultation. It changes the entire assessment, and no doctor is going to be shocked.
Untreated genital infection is the second. An infection that has already been and gone can leave scarring in the delivery pathway. This is why a careful history matters as much as the report.
You can read more about the conditions assessed at this clinic on our conditions page.
A varicocele is the cause that urologists most often identify and can actually operate on, which is why it dominates the conversation. It is a collection of abnormally dilated veins in the scrotum, usually on the left side, and it is thought to impair sperm production partly by raising the temperature around the testicle.
The important nuance, and the one most websites skip, is that having a varicocele does not automatically mean it should be repaired.
The AUA/ASRM guideline is specific about who benefits. It recommends that clinicians should consider surgical varicocelectomy in men attempting to conceive who have palpable varicoceles, infertility, and abnormal semen parameters, with the exception of men who have azoospermia. In the same breath it states that clinicians should not recommend varicocelectomy for men with non-palpable varicoceles detected solely by imaging.
Read that carefully, because it is a clear line:
If a scan has picked up a small varicocele and you have been advised to operate on that basis alone, without a clinical examination finding and without abnormal semen parameters, it is entirely reasonable to ask for a second opinion. That is not a criticism of any individual doctor. It is what the guideline itself says.
Where repair is appropriate, the sperm result does not change overnight. Because a cycle of sperm production takes roughly three months, reassessment is normally done at around three to six months after surgery, not at three weeks.
This is the question everyone actually wants answered, so here it is as plainly as it can honestly be put.
| Cause | Realistic outlook |
|---|---|
| Palpable varicocele with abnormal semen parameters | Correctable surgically in appropriately selected men. Reassessed at around 3 to 6 months. |
| Genital tract infection | Treatable medically. Any scarring left behind may not reverse. |
| Hormonal problems such as hypogonadism | Often manageable under specialist supervision. Requires correct diagnosis first, because the wrong hormone treatment can suppress sperm production further. |
| Anabolic steroid or recreational drug effect | Frequently improves after stopping, over months rather than weeks. Not guaranteed. |
| Obstruction in the delivery pathway | Often addressable surgically, or bypassed by retrieving sperm directly. |
| Ejaculatory dysfunction | Usually manageable. The specific approach depends on the type. |
| Lifestyle factors, including weight, smoking, heat exposure, alcohol | Modifiable, with a realistic effect size. See the section below. |
| Genetic and chromosomal causes | Not reversible. Biological fatherhood may still be possible through sperm retrieval combined with assisted reproduction, depending on the specific finding. |
| Previous chemotherapy or radiotherapy damage | Often not reversible. Stored sperm, if banked before treatment, changes everything. |
| Unexplained abnormal semen analysis | Common. Managed by optimising what is modifiable and moving to assisted reproduction if needed. |
Notice what is missing from that table: any promise. No one can tell you at a first consultation that your count will be normal in six months, and a clinic that does should worry you. What a good assessment gives you is a category, a plan, and a review point.
Our approach to each of these is set out on the treatments page.
They help, but they are consistently oversold, and it is worth separating the two.
What is genuinely worth doing, because it is supported and costs you nothing:

Surgery in male fertility does one of three jobs: it corrects a vascular problem, it reopens or bypasses a blockage, or it retrieves sperm directly.
Which of these applies, if any, depends entirely on the diagnosis. None of them is decided from a semen report alone. Each requires examination, hormone results and in some cases genetic testing first, and each carries its own risks that should be explained to you before you consent.
Earlier than most men do, and at the same time as his partner rather than after her.
The commonly used triggers are straightforward. The NHS advises seeing a doctor if you have not conceived after a year of trying, and sooner if there is already a known fertility problem or if the female partner is 36 or older. The AUA/ASRM guideline frames the same threshold from the male side: infertility is considered present after 12 months of attempting to conceive where the female partner is under 35, shortened to six months where she is 35 or older.
Come sooner than those thresholds, without waiting, if any of the following apply:
There is also a practical argument for going early. A semen analysis is inexpensive, non-invasive and quick, while the standard female workup is neither. Testing the man first is simply the more efficient order, and it is still frequently done last.
A first consultation is a conversation, an examination and a test request. It is not a treatment appointment, and you will not be asked to decide anything on the day.
Bring any previous semen analysis reports with you, even old ones, and even if you were told they were fine. A trend over time is more informative than one recent number.
Our patient education section covers how to prepare for the test itself.
Male fertility assessment sits with andrology, urology and reproductive medicine. It needs a clinician who can examine the scrotum competently, interpret hormone results alongside the semen report, and know when a surgical option is genuinely indicated and when it is not.
Two practical points when you are choosing where to go.
First, an assessment that consists only of a semen report and a supplement is not an assessment. You should be examined.
Second, be cautious of anywhere that quotes you a success percentage before it has seen your results. Male fertility outcomes depend on the diagnosis, your partner's assessment and your combined age. A number offered before any of that is known is marketing, not a prognosis.
Elegance Men's Health Clinic in Surat assesses male fertility as part of a wider men's health service. Surgical and microsurgical procedures are performed by Dr. Ashutosh A Shah. If you are searching more broadly for male fertility services within the group, the Elegance Men's Health Clinic overview at eleganceclinic.in sets out the full scope.
If you are holding a semen analysis report you do not understand, or you have been trying to conceive for a year without success, the useful next step is an examination and a properly instructed test, not a supplement.

Medical disclaimer. This article is general health information and is not a substitute for a consultation, diagnosis or treatment by a qualified doctor. Reference limits quoted are population reference values and are not individual pass or fail thresholds. Do not start, stop or change any medicine, hormone or supplement on the basis of this page. If you have a scrotal lump, sudden scrotal pain or swelling, seek medical assessment promptly, as sudden severe testicular pain can indicate an emergency.
Male infertility is diagnosed through a medical history, a physical examination of the testicles and scrotum, and at least one semen analysis. Where the first semen analysis is abnormal, a second sample about a month later is important before drawing conclusions. Blood hormone tests, a scrotal ultrasound or genetic testing are added depending on what the first results show.
The WHO 2021 lower reference limit is 16 million sperm per millilitre, or 39 million in the total sample. These are reference limits taken from men whose partners conceived within a year, not pass marks. A result slightly below a limit does not mean you cannot father a child, and a result above every limit does not guarantee you can.
It depends entirely on the cause. Low counts due to a palpable varicocele, an infection, a hormonal problem, anabolic steroid use or a correctable obstruction often respond to treatment of that cause. Genetic causes and damage from previous cancer treatment are generally not reversible, though biological fatherhood may still be possible through sperm retrieval with assisted reproduction. No responsible clinician can promise a specific result before the cause is established.
A varicocele can impair sperm production, but not every varicocele needs repair. Surgery is considered for men who have a varicocele that can be felt on examination, abnormal semen parameters, and who are trying to conceive. A varicocele found only on ultrasound, which cannot be felt on examination, is not on its own a reason to operate.
Around three months, because that is roughly how long one full cycle of sperm production and transport takes. This is why a repeat semen analysis after a lifestyle change, a course of treatment or varicocele surgery is normally done at three months or later. Improvements are not visible in a test done a few weeks after the change.
Often yes. Zero sperm in the ejaculate, called azoospermia, may mean either that sperm are being produced but blocked on the way out, or that production itself is impaired. The first step is distinguishing between the two using examination, semen volume, semen pH and a serum FSH level. Where sperm are present in the testicle, they can be retrieved surgically and used with assisted reproduction.
After 12 months of regular unprotected sex without conception, or after six months if the female partner is 35 or older. Come sooner, without waiting, if the man has had an undescended testicle, testicular surgery or injury, chemotherapy or radiotherapy, a genital infection, a scrotal lump or ache, difficulty with erections or ejaculation, or a previously abnormal semen analysis that was never repeated.
