How to Increase Sperm Count Naturally: What Helps

You can support your sperm count with everyday changes: cutting back on alcohol, stopping smoking, getting to a healthy weight, staying active, eating well and keeping things cool down below. None of it is magic, and it takes time. Sperm take roughly three months to make, so you won’t see the effect overnight. But these steps are the ones the NHS and NICE point to, and they’re mostly free.

Let’s be real: nobody enjoys wondering about this. Whether you’re trying for a baby or just want to know where you stand, here’s what the evidence says, what it doesn’t say, and how to find out your starting point without the awkward conversations.

TL;DR

  • The best-supported steps are drinking within 14 units a week, stopping smoking, losing weight if you’re overweight, and staying active.
  • A varied, balanced diet is linked with better semen quality. Think fish, fruit, veg, nuts and wholegrains, and go easy on processed meat and sugary drinks.
  • Vitamins and supplements have thinner evidence. Treat them as a possible extra, not a fix, and check with a pharmacist or GP first.
  • Give any change around three months before judging it.
  • See a GP if you’ve been trying for a year (six months if your partner is 36 or over) without a pregnancy.

What “sperm count” actually means

Sperm count is the number of sperm in your semen. A semen analysis also looks at how well the sperm move (motility) and their shape. When people say “sperm quality” they usually mean all of that together.

A lower count doesn’t mean you can’t have a child. The NHS says a low sperm count can still allow natural conception, and couples trying should have sex every 2 to 3 days without contraception. Think of lifestyle changes as stacking the odds a bit more in your favour.

Lifestyle changes with the strongest backing

The NHS list of steps that may help improve sperm count is short and practical:

  • Drink no more than 14 units of alcohol a week.
  • Lose weight if you’re overweight.
  • Stop smoking.
  • Wear loose-fitting underwear.
  • Avoid workplace chemicals such as pesticides, solvents and some heavy metals.
  • Avoid recreational drugs, including anabolic steroids and cocaine.

A 2016 evidence review backs the same core four: weight reduction, exercise, stopping smoking and moderating alcohol. It found that evidence for complementary therapies and many supplements rested on small trials. A 2024 review agrees that smoking, alcohol and drug use harm male fertility, and that low physical activity goes with poorer sperm quality, while calling for more rigorous research.

So where should you start? Pick the one that applies to you most. If you smoke, that’s it. If you drink most nights, that’s it. One change done properly beats five half-hearted ones.

Alcohol

NICE (2026) says excessive alcohol harms semen quality, while drinking within the UK Chief Medical Officer limit of 14 units a week, spread over several days, is unlikely to affect it. That’s reassuring. You don’t need to go teetotal, but a weekend binge is not the same as a pint or two across the week.

Fourteen units is about six pints of 4% beer or seven medium glasses of wine. If you’re not sure how your week adds up, track it for seven days. Most people are surprised. Alcohol also has knock-on effects on weight, sleep and energy, which is covered well in this piece on alcohol and fat loss.

Smoking

NICE says smoking is associated with reduced semen quality, although its effect on male fertility is uncertain. It also notes that stopping improves your general health. That alone makes it worth doing, whatever your sperm count turns out to be. Your GP or local stop smoking service can set you up with free support.

Weight and exercise

NICE says men with a BMI of 30 kg/m² or above have an increased risk of reduced fertility. A Birmingham NHS leaflet recommends exercise to help maintain a healthy weight and gives a BMI of 18.5 to 24.9 as the recommended range.

You don’t need a gym membership. Brisk walking, cycling, swimming, five-a-side or a home routine all count. The aim is steady movement most days and slow, sustainable weight loss if you need it, not crash dieting.

Heat, underwear and cycling

The NHS advice is simply to wear loose-fitting underwear. We haven’t found firm UK guidance on cycling, so keep it sensible: if you cycle a lot, take breaks and wear comfortable kit. Equally, a lot of long hot baths, a laptop on your lap and sitting for hours are worth swapping out where you can. Testicles prefer to run a little cooler than the rest of you.

Steroids, testosterone and recreational drugs

This one matters more than most people realise. Anabolic steroids, including self-prescribed testosterone, can switch off your body’s own sperm production. The Birmingham NHS leaflet says that stopping steroids may allow recovery of testosterone and testicular function for most men, but recovery isn’t guaranteed and can take time. If you’ve used them, talk to your GP before you start trying for a baby, so they can guide you safely.

Eating for better sperm

There’s no single superfood. What the research does show is that overall eating pattern matters.

A 2022 systematic review and meta-analysis found that men eating healthier dietary patterns had, on average, 6.88 million/ml higher sperm concentration, 16.70 million higher total sperm count and 5.85 percentage points higher progressive motility. The authors urged caution in interpreting the results, because these are averages across different studies.

A 2023 food review links fish, shellfish, poultry, cereals, vegetables, fruit and low-fat dairy with better semen quality. Processed meat, sugary drinks, sweets and alcohol are linked with poorer quality. These are associations, not proof that one causes the other.

Foods associated with better or poorer semen quality

The Birmingham NHS leaflet keeps it simple: a healthy balanced diet, at least five portions of fruit and veg a day, carbohydrates, lean meat, fish and protein, and antioxidant-rich foods such as blueberries and tomatoes.

A simple day of eating

Meal Easy swap that fits the evidence
Breakfast Porridge or wholegrain cereal with blueberries, instead of a sugary pastry
Lunch Tuna or chicken salad with tomatoes, instead of a processed meat sandwich
Snack A handful of nuts and a piece of fruit, instead of sweets
Dinner Salmon or other fish with veg and wholegrain rice or potatoes
Drinks Water, tea or coffee instead of fizzy drinks

Aim for five portions of fruit and veg a day and fish most weeks. It’s the sort of change you can keep up, which is the whole point.

Vitamins and supplements: what to know

This is the part people search for most, so let’s keep it straight.

The Birmingham NHS leaflet lists vitamins C, E, B6 and B12, CoQ10, zinc and acetyl-L-carnitine as involved in sperm production, function or protection. It gives no recommended amounts.

A 2017 systematic review found generally favourable associations between semen quality and omega-3 fats, vitamins C and E, beta-carotene, selenium, zinc, folate and vitamin D, but stressed that observational evidence can’t establish cause and effect. A separate review found that fatty acid supplementation may help motility, though we’d treat that as one piece of a bigger picture.

The HFEA, the UK fertility regulator, says antioxidants and vitamins may help some sperm problems, but evidence is poor and more research is needed before they can be considered proven.

What does that mean in practice?

  • Food first. Most of these nutrients are in fish, nuts, seeds, fruit, veg and wholegrains.
  • If you want a supplement, a standard multivitamin made for men is a sensible, low-fuss route.
  • Check the label and don’t stack several products that contain the same mineral. Zinc, for example, can cause problems in excess.
  • Ask a pharmacist or your GP first if you take regular medication or have a health condition.
  • Be wary of any product promising a guaranteed jump in sperm count. No supplement can promise that.

How long until you see a difference?

Sperm production takes about three months from start to finish. The Irish Examiner, quoting University of Dundee fertility specialist Sarah Martins Da Silva, reports that lifestyle changes may show up in semen testing after roughly three to five months.

That’s useful for planning:

  1. Make your changes now, and keep them going.
  2. Don’t judge the result at week three. Your body is still working through sperm that started developing before you changed anything.
  3. Around the three-month mark, check in on how you’re doing.

It’s also why one test taken once doesn’t tell the whole story. The NHS usually repeats a possible abnormal semen analysis around three months later, because numbers can vary from sample to sample.

Finding your starting point at home

It’s much easier to stay motivated when you know where you started. A lot of men put off finding out because it feels awkward or because booking an appointment is a hassle.

Our Fertility Insight rapid test kits include a sperm concentration test, alongside tests for hormones such as FSH, LH and HCG. You do it at home in private, follow the full instructions in the box and get your result in about 15 minutes. If you want more detail on how it works for couples, our guide to testing fertility at home walks you through it.

A sensible rhythm is to test once as a baseline, make your lifestyle changes, then test again after about three months. That way you’re comparing like with like.

One thing to keep in mind: a home test gives you a quick, private indication. If your result suggests a low concentration, or you’re simply worried, take it to your GP, who can arrange a full semen analysis and further tests.

Our perspective

We built Rapidtest around a simple idea: you shouldn’t have to wait for a problem to get loud before you look into it. Fertility is a perfect example. Plenty of men quietly wonder about their sperm count for months, and some never raise it at all, because it feels awkward.

That’s why we think starting with a private baseline makes sense. Our kits are CE-certified and designed to give you a result in 15 minutes at home, with no queues and no appointment. Know where you stand, make the lifestyle changes that the NHS and NICE point to, then check again.

We also think honesty is part of looking after yourself. Lifestyle changes help many men, but they aren’t a guarantee, and a home test is a starting point rather than a diagnosis. If your result worries you, speaking to your GP is the right next step, and having your own result in hand makes that conversation easier.

Our kits ship discreetly, UK shipping is free, and we back them with a 60-day refund guarantee if the kit doesn’t work. Taking the first step should feel easy.

When to see a GP

Lifestyle changes help many men, but not everyone. The Birmingham NHS leaflet notes that for some men lifestyle changes may not improve sperm quality, and medical help may be needed. That’s no failure on your part. It’s common, and there are routes forward.

See your GP if:

  • You’ve had regular unprotected sex for more than a year without a pregnancy, or for six months if your partner is 36 or over, per NHS guidance. NHS inform says to go sooner if you have specific fertility concerns or health conditions.
  • A semen analysis comes back abnormal. The NHS usually repeats it around three months later and refers persistent problems for specialist tests.
  • You’ve used anabolic steroids or self-prescribed testosterone and want to start a family.

Trying for a baby is a team effort, so it’s worth both of you getting checked rather than assuming it’s one person.

FAQ

Can exercise improve sperm health?

Regular exercise helps you keep to a healthy weight, and the NHS lists losing weight if you’re overweight as one step that may improve sperm count. Reviews also link low physical activity with poorer sperm quality. Keep it steady and enjoyable rather than extreme.

Which vitamins may help sperm count?

The Birmingham NHS leaflet lists vitamins C, E, B6 and B12, CoQ10, zinc and acetyl-L-carnitine as involved in sperm production and protection. The HFEA says evidence that supplements help is still poor. Get them from food where you can, and ask a pharmacist before taking a supplement.

How long does it take to improve sperm quality?

Sperm production takes about three months, so expect changes to show in testing after roughly three to five months. Keep your habits consistent during that time. Then retest to see how you’re getting on.

Does drinking alcohol affect sperm count?

NICE says excessive alcohol harms semen quality, while staying within 14 units a week, spread over several days, is unlikely to affect it. Cutting down is a simple first step if you usually drink above that.
