How to Increase Sperm Count and Motility: A 90-Day UK Guide

Why a 90-day plan makes sense

Sperm cells are made continuously, and a full cycle of sperm production takes around three months. That is why NICE's 2026 fertility guideline recommends a repeat confirmatory laboratory semen analysis ideally three months after an abnormal result. If there is no sperm or a severe deficiency, NICE advises repeating sooner.

Think of 90 days as a useful window to make sustainable changes and reassess—not a guaranteed treatment course. Infection, hormone problems, varicocele, medicines, genetic conditions and other causes may need clinical investigation. Semen results also vary between samples, so a single result rarely gives the complete picture.

When should you test, and when should you see a GP?

The NHS advises seeing a GP if pregnancy has not happened after one year of regular unprotected sex, or after six months if your partner is 36 or over. You can seek advice earlier if either partner has a known or suspected fertility issue, such as prior cancer treatment, a testicular problem or a possible sexually transmitted infection. This is guidance on when to investigate—not a rule that prevents you from raising concerns sooner.

A GP can arrange a laboratory semen analysis, which looks at sperm concentration, movement and shape. If a first laboratory result is abnormal, the NHS and NICE recommend confirmation. If you have testicular pain, swelling, blood in semen or another concerning symptom, ask for medical advice rather than waiting for a home test or the end of this plan.

Five evidence-led steps to support sperm count and quality

These steps support general and reproductive health. Their effect on an individual's sperm count, motility or chance of conception varies. If a cause is medical, lifestyle changes alone may not solve it.

1. Stop smoking and review nicotine use

NICE links smoking with poorer semen quality, although the precise effect on fertility is uncertain. If you smoke, seek help to stop. If you vape, discuss your nicotine use with a clinician rather than assuming it has no fertility implications. Rules for publicly funded fertility treatment vary locally, so do not rely on a blanket claim about every NHS area.

2. Limit alcohol and avoid recreational drugs or anabolic steroids

Excess alcohol can harm semen quality. NICE says drinking within the UK guidance of no more than 14 units a week, spread over several days, is unlikely to affect semen quality. The NHS also advises avoiding recreational drugs such as cocaine and anabolic steroids. Tell your GP about prescribed testosterone or other medicines: some can affect sperm production, but do not stop prescribed treatment without medical advice.

3. Work towards a balanced diet and weight

If you are overweight, the NHS advises weight loss as one step that may help low sperm count. Aim for a varied diet with vegetables, fruit, whole grains, protein and healthy fats rather than relying on a short list of “fertility superfoods”. Foods containing zinc, folate and other nutrients can be part of that diet, but no single food is proven to repair poor motility or guarantee pregnancy. Choose sustainable activity and discuss major weight changes with a clinician if needed.

4. Be sensible about heat and workplace exposure

Higher scrotal temperature is associated with poorer semen quality. Loose underwear is a reasonable comfort choice, but NICE says it is uncertain whether switching underwear improves fertility. Avoid prolonged, unnecessary heat where practical. If your work involves pesticides, solvents or heavy metals, ask your employer's occupational health team about protection; the NHS and NICE both flag workplace exposure as relevant.

5. Treat supplements as optional, not proven fixes

Searches for “male fertility supplements UK”, CoQ10, zinc, vitamin D, maca and ashwagandha often lead to strong promises. The evidence is less certain. A Cochrane review found that antioxidants might help some subfertile men, but the evidence for live birth was very uncertain and did not establish the best ingredient or dose. Correct a documented deficiency if your clinician recommends it; do not let supplements replace testing or investigation.

Your practical 90-day sperm health plan

1. Days 1–14: establish a baseline. Note how long you have been trying to conceive, relevant symptoms, medicines and lifestyle factors. Speak to a GP if the NHS timing or an earlier-risk reason applies. If you want a private first indication, consider the U-Test Male Fertility Test Kit and keep its instructions and result.
2. Weeks 3–8: keep changes consistent. Stop smoking, avoid recreational drugs, stay within alcohol guidance, eat a balanced diet and address weight or workplace exposures where relevant. If trying naturally, the NHS suggests sex every two to three days without contraception.
3. Weeks 9–12: review and follow up. If a laboratory semen analysis was abnormal, follow the clinician's timing for a repeat—usually around three months. Do not wait three months to repeat a result showing no sperm or severe deficiency; NICE advises a sooner repeat. Bring any home result to the appointment as context, not as a substitute for lab results.

What is a normal sperm count or motility result?

The 2026 NICE guideline uses reference values from the WHO semen manual for laboratory semen analysis. Commonly discussed lower reference values are:

These are reference values, not pass/fail fertility cut-offs. The WHO manual warns that semen values alone do not create a sharp boundary between fertile and infertile people. A result above a reference value does not guarantee conception; a result below one does not mean pregnancy is impossible. A clinician interprets the complete result and your circumstances.

Can an at-home sperm test measure motility?

Not every home sperm test measures the same thing. The U-Test Male Fertility Test Kit is marketed as a sperm concentration test. Its visible packaging shows a qualitative cassette result after sample preparation. On the evidence currently available, we do not describe it as a precise sperm count, a motility test, or a full semen analysis. Follow the current leaflet for collection, timing, result interpretation and invalid tests; packaging indicates that sample preparation takes longer than the cassette read time alone.

If your result concerns you—or if conception is taking longer than expected—speak to a GP. A normal-looking home result cannot rule out low motility, abnormal morphology or other fertility factors. If you specifically need to know how well sperm move, ask for a laboratory semen analysis.
