Semen Analysis
A semen analysis is one sample of ejaculate looked at under a microscope. The lab measures how much there is, how many sperm are in it, how many are swimming and how they are swimming, and what proportion are normally shaped. It is the first test on the male side, it costs less than almost anything else in fertility medicine, and it decides what happens next.
The thing to hold on to before you open the report is that one sample is a snapshot, not a verdict. The same man tested three times in three months can produce three quite different sets of numbers, and the reference values printed alongside them are not a pass mark. They are the bottom of the range for men whose partners conceived within a year, which is a very different claim.
I have sat with people who took a single low number as a diagnosis and started planning around it, and with others whose repeat test a month later was unremarkable. Neither reaction was warranted by one piece of paper. Read the report, then read the repeat.

Who it’s for
Anyone with testicles at the start of a fertility investigation, which in practice means anyone who has been trying to conceive for about a year without success, or six months if the female partner is over thirty-five. It should be requested at the same time as the female partner's tests rather than after them.
Test earlier if there is a reason to. An undescended testicle in childhood, previous cancer treatment, surgery in the groin, a significant testicular injury, mumps after puberty, or any history of anabolic steroid or testosterone use all justify testing on day one rather than after a year of waiting.
The other groups are people about to start treatment that damages sperm production, who need the test before sperm freezing, and anyone planning to donate, where the screening is more extensive. There is no age limit, no referral requirement in many countries, and no preparation beyond the abstinence window. See male fertility for what follows a poor result.
The week before the test
Keep the abstinence window inside the range the clinic gives you rather than saving up for as long as possible. A much longer gap raises the volume and the count while lowering the proportion that are still swimming well, which makes the result harder to interpret rather than better.
How it’s done
You produce a sample by masturbation into a sterile pot, ideally in a private room at the clinic, because getting it to the lab quickly matters. If you produce it at home, it has to arrive within roughly an hour and stay near body temperature on the way, which in cold weather means carrying it against your body. No lubricant unless the clinic supplies one that is safe for sperm, no condom unless it is a specialist collection condom, and the whole sample matters, since the first part of the ejaculate carries most of the sperm.
The lab waits for the sample to liquefy, then works through a standard set of measurements. Volume, in millilitres. Concentration, meaning sperm per millilitre. Total count, which is those two multiplied and is the number that matters more than concentration alone.
Motility, the share that are moving at all, and progressive motility, the share that are moving forward in a useful way rather than twitching in place. Morphology, the share with a normally shaped head and tail, assessed against strict criteria. Many labs add vitality, white cell count and pH.
Each number is printed next to a reference value from the World Health Organization's laboratory manual, now in its sixth edition, published in 2021. Those lower limits sit at about 1.4 millilitres of volume, 16 million sperm per millilitre, 39 million in total, 42 per cent motile, 30 per cent progressively motile and 4 per cent normal forms. The last one surprises everybody. Four per cent normal shapes is the reference limit, not a disaster, because strict morphology criteria fail almost every sperm on close inspection.
Check which edition your own report was scored against. Plenty of laboratories still use the fifth edition from 2010, and its thresholds differ. Two reports on the same sample can disagree about whether a number sits below the line.
Understand what those limits are. They are the fifth centile of men whose partners conceived within twelve months, which means one in twenty fertile men falls below each of them. A number below the line makes conception less likely across a population. It does not tell an individual he cannot father a child, and a number above the line does not promise he can.
On the morning of the test
Use the room at the clinic if one is offered, even if the idea makes you want to sink through the floor. It removes the travel time and the temperature problem in one move, and the staff have seen every version of this before breakfast.
After semen analysis
There is nothing to recover from. You hand over a pot and leave, and nothing about the test changes anything in your body.
What follows is waiting, and then, if the result was abnormal, waiting again for a repeat. That gap is doing real work rather than wasting time. Sperm take roughly three months to be produced, so a fever, a heavy drinking stretch, a course of medication or a stressful few weeks can show up in a sample taken well after the event, and a second test after a proper interval separates a bad patch from a stable picture.
| Days before | Abstain for the window the lab asks for, usually two to seven days. Shorter or much longer both skew the result. |
|---|---|
| Day 0 | Sample produced, ideally in a room at the clinic. If produced at home, it needs to reach the lab within about an hour, kept near body temperature. |
| Hours 1–2 | The lab lets the sample liquefy, then measures volume, concentration, motility and vitality under a microscope. |
| Days 2–7 | Report issued, with each parameter given as a number next to a reference value. |
| Weeks 6–12 | If anything was abnormal, a repeat sample. A gap of at least a few weeks makes the second test worth having. |
| Months 3+ | If something has changed, medication, an illness, a varicocele repair, this is the earliest a retest reflects it. Sperm take roughly three months to be made. |
When the result lands
Ask for the actual report rather than a verdict over the phone, and keep a copy. Normal and abnormal are not useful words here, and if you end up at another clinic later, having the original numbers saves you repeating the whole thing.
Risks and complications
The test itself carries no physical risk. The risks are all in how the result gets used.
The first is being labelled on one sample. Variation between samples from the same man is large, so a single low result acted on immediately can send a couple towards treatment they may not need. The second is the mirror image, where a normal result is treated as the male side being closed. A standard analysis says nothing about sperm DNA quality, and a normal-looking report in a couple with unexplained infertility does not rule out a male contribution.
The third is the add-on. Sperm DNA fragmentation testing measures breaks in the genetic material inside the sperm, and it does correlate with miscarriage and with poorer outcomes in some studies. What is contested is whether knowing the result changes what anyone should do, and the professional bodies have been cautious about recommending it routinely. It costs extra and is often sold as a natural next step after a normal analysis. I would ask what would be done differently depending on the answer before paying for it, and treat a shrug as the answer.
Home test kits are the fourth. Most measure concentration alone, sometimes motility, and report a pass or a fail against a single threshold. That misses total count, progressive motility, morphology, volume and everything else on the report. A reassuring home result in a couple who have been trying for a year is not a reason to skip the proper test.
Semen analysis results
The report is read as a pattern rather than a scorecard, and the common patterns point in different directions.
- Low concentration or total count. Mild reductions often conceive naturally or with IUI. Severe reductions point towards IVF with ICSI, and towards a fuller assessment with hormone tests and, if the count is very low, genetics.
- Poor motility. Fewer sperm moving forward. Collection and transport problems cause some of it, so it is one of the parameters most worth repeating before acting on. Persistently poor motility points towards ICSI.
- Abnormal morphology in isolation. The weakest of the three on its own, and the most over-interpreted. With the rest of the report normal, it rarely changes the plan by itself.
- Azoospermia, no sperm at all. Always repeated and confirmed, including a spin of the sample to look for the occasional sperm. Then the question is whether production has failed or the plumbing is blocked, which hormone tests, examination and genetics answer, and which decides whether surgical sperm retrieval is likely to find anything.
The genuinely modifiable factors are worth knowing, and worth stating without overselling them. Heat, meaning saunas, hot tubs, laptops and some occupations. Smoking and heavy drinking. Significant excess weight. Some prescription medications, which is why the drug list matters.
Anabolic steroids and prescribed testosterone, which suppress the signal that drives sperm production and commonly take the count to zero, sometimes for many months after stopping. Changing these tends to move the numbers modestly rather than transform them, and the honest version is that stopping testosterone is the one with a large and well-documented effect.
Alternatives to semen analysis
There is no substitute for a laboratory semen analysis, only things that sit around it. A home kit is a screening device and a poor one, useful mainly for reassurance between proper tests. DNA fragmentation testing is an addition rather than an alternative, and belongs to the contested column.
The real alternative to a second opinion on a worrying result is the same test again, at a different laboratory if you want the comparison, after a gap of at least a few weeks. It is cheaper than anything else you could do with the money and it answers the question a single sample left open.
Semen analysis cost
This is the cheapest useful thing in fertility medicine, which is exactly why it should not be left until last. Through a family doctor in a public system it is often free or nominal. Privately it is usually a small standalone fee, although fertility clinics frequently fold it into a first-consultation package where the price looks larger than the test.
Watch two things in a quote. Whether the repeat test is included or charged again, since you are likely to need one. And whether DNA fragmentation or antisperm antibody testing has been added by default, because both are extras.
| Country | Self-pay | Public / insurance |
|---|---|---|
| United States Standalone lab tests sit at the low end; fertility clinics bundling it with a consultation sit at the top | $50–$300 | Commonly covered when ordered as part of an infertility workup; diagnostic infertility cover varies by plan and state |
| United Kingdom Private clinics often quote the test inside a first-consultation package | £70–£200 | Free on the NHS when your GP refers you; waiting times vary by area |
| Thailand Usually same-week results; DNA fragmentation, where offered, is charged separately | $30–$90 | Self-pay for international patients |

Choosing a clinic for semen analysis
The sample is the easy part. The variable that decides whether the report is worth anything is the laboratory. Counting sperm and grading how they move is a manual skill, with real variation between technicians and between machines.
Three questions are worth asking when you book. Whether the andrology laboratory is accredited, and by whom. Accreditation is what forces the internal quality control that keeps one technician's count in line with another's.
Whether the clinic has a production room on site, which removes the travel time and the temperature problem in one move.
And which edition of the WHO manual the report is scored against. A laboratory that cannot answer that quickly is not one I would trust with the numbers.
The fourth thing is not about the laboratory at all. Ask whether a doctor goes through the result with you, or whether a report simply arrives by email. I have watched people sit on a frightening set of numbers for weeks because nobody was booked to explain them. The explanation is usually the part that changes what happens next.
When you book
Ask whether the appointment includes someone talking you through the result, and book that conversation at the same time as the test. Otherwise the report lands in your inbox on a Friday afternoon, with nobody to ask about it.
Frequently asked questions
Does a below-reference result mean I am infertile?
No. The reference values are the fifth centile of men whose partners conceived within a year, so one in twenty fertile men falls below each one. See how it's done for what the numbers actually mean.
How long should I abstain before the test?
Usually two to seven days, and the lab will tell you its own window. Much longer is not better, because it raises the count while lowering the share still swimming well.
Should I repeat an abnormal test?
Yes, after a gap of a few weeks. Samples vary a great deal between weeks, and decisions should not rest on one. See recovery.
Are home sperm tests worth it?
Only as rough reassurance. Most measure count alone and miss motility, morphology and volume, so a pass does not mean the male side is clear. See risks.
Will the test show whether the sperm DNA is damaged?
No. That is a separate test with contested value. Ask what would change depending on the answer before paying for it.
