Male fertility screening usually means one thing in practice: a semen analysis, sometimes alongside a hormone blood test. It's the simplest, fastest way to find out whether sperm might be part of the picture when you're trying to conceive, and it's a lot less invasive than most of what your partner gets asked to go through first.
👉 It's a genuinely easy first step, and male factors are involved in around half of all fertility struggles.
I'll be honest, this is one of those topics that made me a bit annoyed on other men's behalf while I was researching it. So much of the TTC conversation defaults to tracking her cycle, her hormones, her scans, and male fertility screening barely gets mentioned until months in, if at all. It's quick, it's cheap relative to almost everything else in this process, and it can save a lot of wasted time.
What Male Fertility Screening Actually Involves
At its core, male fertility screening is a semen analysis (also called a sperm test): a lab looks at a sample under controlled conditions and measures how much sperm is there, how well it moves, and how normally it's shaped.
Some clinics extend this into a wider screening panel, adding a hormone blood test (testosterone, FSH, LH) if the semen analysis flags something worth investigating further. But the semen analysis itself is the actual starting point almost every time.
It's genuinely one of the least invasive tests in the whole TTC process. No scans, no injections, no waiting through a menstrual cycle to get a result. If you're timing things around ovulation while you wait for results, our home insemination and tracking kit is worth a look.
What Does a Sperm Test Actually Check?
Labs measure your sample against reference values published by the World Health Organization. The most recent version (the WHO's 6th edition manual, 2021) set these as the lower reference limits:
- Volume: at least 1.4 mL
- Concentration: at least 16 million sperm per mL
- Total sperm number: at least 39 million per ejaculate
- Total motility: at least 42% of sperm moving at all
- Progressive motility: at least 30% moving forward purposefully, not just twitching in place
- Morphology: at least 4% of sperm with a normal shape
- Vitality: at least 54% of sperm alive
I want to flag something honestly here, because I got it wrong myself the first time I looked into this: a lot of content online (including, until I checked properly, an older version of this exact article) quotes slightly different numbers, like 15 million/mL or 40% total motility. Those are actually the WHO's older 2010 (5th edition) figures, not the current ones. The thresholds shifted slightly in 2021, generally downward, which matters because it changes what counts as "within range." Always worth checking which edition a source is actually quoting.
These are reference values, not pass/fail lines. The WHO itself is explicit about this in the 6th edition: they represent the lower end of what was measured in a large group of men whose partners conceived naturally within 12 months, not a hard cutoff between "fertile" and "infertile." A result just under one of these numbers doesn't mean you can't conceive naturally. It means it's worth a conversation with a doctor about what it might mean for you specifically.
Extended testing, if your GP or a fertility specialist thinks it's warranted, can also include DNA fragmentation testing, sperm chromatin integrity testing, and an acrosome reaction test, but these aren't part of a standard first screening.
📌 If any of this terminology is new to you, our TTC glossary breaks it down further.
How Is Male Fertility Screening Actually Done?
You'll usually be asked to abstain from ejaculating for somewhere between 2 and 7 days beforehand, since abstinence time genuinely affects the results. Too short and volume/concentration can read low; too long and motility tends to drop.
From there, you've got two real routes:
- At a clinic or lab. You provide the sample on site, usually by masturbation into a sterile container, and it goes straight to analysis.
- At home, with an approved kit. You collect the sample at home, then it needs to reach the lab, typically within an hour, kept close to body temperature the whole way. This matters more than people expect. Sperm motility genuinely drops the longer and colder the journey, so a home kit with a proper insulated, timed delivery process isn't a nice-to-have, it's part of what makes the result meaningful.
Because a single sample can vary a fair amount from one day to the next, most clinics recommend two samples spaced two to four weeks apart before drawing any real conclusions, rather than treating one result as the whole story.
When Should You Actually Get Screened?
There's no rule that says you have to wait. You can get male fertility screening done at any point, and doing it earlier rather than later genuinely just gives you more useful information sooner.
That said, it's especially worth prioritising if:
- You've been trying to conceive for around 12 months without success. This lines up with NICE's current fertility guidance, which recommends both partners get assessed after a year of trying, in the absence of a known reason to test sooner.
- You're about to start IUI or IVF. Clinics need this data before treatment anyway, so getting it early avoids delays later.
- You have known risk factors: a past infection, a varicocele, low testosterone, undescended testicles as a child, or previous chemotherapy or radiotherapy.
- You just want clarity and reassurance before you're months into trying.
It wasn't about waiting for a "right time," it was about realising there wasn't a good reason to put it off once we knew it existed.
What Do the Results Actually Mean?
Here's a worked example of what a real set of results might look like, and how you'd read it:
| Parameter | Result | WHO Lower Reference Limit |
|---|---|---|
| Volume | 2.0 mL | 1.4 mL |
| Concentration | 20 million/mL | 16 million/mL |
| Total motility | 38% | 42% (slightly low) |
| Progressive motility | 27% | 30% (slightly low) |
| Morphology | 3% | 4% (borderline) |
In this example, volume and concentration are comfortably within range, but motility and morphology are a little below the reference limits. That doesn't automatically mean infertility. It usually means natural conception might take somewhat longer, and it's genuinely worth optimising the factors that are within your control, alongside a conversation with a doctor about whether further investigation makes sense.
Many of these numbers can shift with time and consistent changes, which we've covered in detail in how to improve sperm quality naturally.
What Affects Male Fertility Screening Results?
A few things genuinely move the needle here, for better or worse.
Heat and Everyday Habits
Prolonged heat exposure (laptops resting directly on your lap, hot tubs, very tight underwear) can measurably affect sperm production. Alcohol, smoking, and obesity are all linked to reduced count and quality too.
Illness and Recent Fevers
A fever, flu, or a virus like COVID can suppress sperm production for weeks to months afterward, since sperm takes roughly 74 days to fully develop. If you've been unwell recently, that's worth mentioning when you book your test, and possibly worth waiting on.
Stress, Sleep, and Certain Medications
Chronic stress, poor sleep, and some medications (including certain NSAIDs and testosterone supplementation) can all interfere with sperm production. None of this is usually the whole story on its own, but it adds up.
📌 Our guide on natural ways to boost fertility covers what actually helps, in practical terms.
What If Your Results Come Back Low?
Repeat the test first. A single low result isn't the full picture. Most clinics suggest waiting 8 to 12 weeks (roughly one full sperm production cycle), addressing anything obvious in the meantime, then retesting.
Look at lifestyle factors you can actually change. Losing weight if your BMI is over 25, reducing alcohol, quitting smoking, and adding antioxidant-rich foods or supplements (zinc, folate, vitamin C, CoQ10 are the ones most commonly discussed) are the realistic first moves.
Get the medical follow-up if numbers stay low. This usually means hormone blood tests (testosterone, FSH, LH) and sometimes an ultrasound to check for a varicocele or a blockage -- the HFEA's real guidance on infertility surgery for men covers what a referral for this can actually involve. If a delay before treatment is likely, sperm freezing is worth discussing with your clinic too.
📌 The emotional side of this is real as well. Our piece on coping with TTC stress is worth reading if this stage is weighing on you.
How Much Does Male Fertility Screening Cost in the UK?
A private semen analysis in the UK typically costs somewhere in the region of £150 to £250, depending on the clinic and whether it's a basic or extended panel.
NHS availability varies by area. If you've been referred by a GP after 12 months of trying (or sooner with a clear clinical reason), it may be available free through your local fertility service, though waiting times differ a lot region to region. It's always worth asking your GP directly what's available locally before paying privately.
FAQ: Male Fertility Screening
What is male fertility screening?
It's mainly a semen analysis (sperm test), which checks sperm count, movement, and shape, sometimes alongside a hormone blood test if something in the initial results needs a closer look.
When should I get male fertility screening done?
Around 12 months of trying without success is the standard guidance, but sooner is sensible if you have known risk factors, are about to start IUI or IVF, or simply want clarity earlier.
Can a low sperm test result improve over time?
Yes, in many cases. Sperm takes about 74 days to develop, so lifestyle changes (diet, alcohol, heat exposure, stress) can genuinely shift results within a few months.
How accurate is a sperm test?
The lab analysis itself is reliable, but results can vary meaningfully between samples from the same person, which is exactly why repeat testing is standard practice rather than a red flag.
How much does male fertility screening cost in the UK?
Privately, typically £150 to £250. It may be available free on the NHS with a GP referral, depending on your local fertility service and how long you've been trying.
Does a low result mean I'm infertile?
Not on its own. WHO reference values mark the lower end of a range seen in men whose partners conceived naturally, not a strict fertile/infertile cutoff. A below-range result is a reason to look closer, not a diagnosis by itself.
Can I do male fertility screening at home?
Yes, with an approved home collection kit, as long as the sample reaches the lab within the required window (usually about an hour) and stays close to body temperature throughout.
A semen analysis is honestly more useful as a starting point than most people expect going in. It's not a verdict, it's information, and information is the thing that actually lets you make a real decision about what to do next, rather than sitting in months of uncertainty wondering if it's worth asking. It's one piece of a much bigger picture you're both figuring out together, and getting it early just means you get to figure the rest out with better information, sooner.
