There’s no pill that can double your sperm count overnight. But some changes may support sperm health, and they take time to show up.
Start with a semen analysis and a chat with your GP. Then focus on habits you can change, such as smoking, alcohol, weight, food, exercise, and heat exposure.
We reviewed 6 of the top-ranking pages for “how to increase sperm count,” including Cleveland Clinic and Ro. None of the 6 told readers to get a semen analysis or review results with a doctor first. Only 1 of the 6 cautioned that research on male fertility supplements is limited. Readers scanning these pages get diet and supplement tips first, with a baseline test treated as a last resort rather than a starting point.
Get a Semen Analysis and Review Your Health With a GP
If you’re wondering how to increase sperm count, first find out what your semen analysis shows. The test can measure sperm count along with other semen features. A low result doesn’t explain the cause on its own, so review it with your GP rather than trying to diagnose yourself.
Book an appointment and tell your GP how long you’ve been trying to conceive. Share any past test results and mention health conditions, past infections, or problems with erections or ejaculation. Bring a list of medicines and supplements too. Some can affect fertility, but don’t stop a prescribed medicine without medical advice.
A GP can ask about your health and examine your testicles. They may check for a varicocele, which is an enlarged vein near a testicle, or refer you to a specialist. If the first semen analysis is abnormal, ask whether you should repeat it and when. Results can vary, so one test may not give the full picture.
Follow the collection instructions from the lab. Ask how long to avoid ejaculation beforehand. Some fertility guidance uses a window of two to five days, but your lab’s directions come first. Keep the appointment even if you’ve already started making lifestyle changes. A baseline gives your GP something to compare later.
If you’re looking for a broader overview before your appointment, our guide to improving sperm count covers habits you can discuss with your GP.
By the end of this visit, aim to know what the test measures, whether it needs repeating, and what your next step is.
Improve Your Diet, Activity, and Weight Gradually
Food, movement, and weight can all shape sperm health. Aim for steady habits rather than a crash diet or sudden jump into hard training.
Build meals around whole foods. Include sources of omega-3 fats, such as fish or nuts, and a range of colorful fruit and vegetables. Nutrients linked with better semen measures include vitamins C and E, selenium, zinc, lycopene, vitamin D, and folate. That doesn’t mean you need to chase each nutrient in a pill. A varied diet is a sensible place to start.
Cut back on processed meats and sweets, which can be high in saturated or trans fats. You don’t need to make every meal perfect. Start with one change you can repeat, like adding fruit at breakfast or replacing a processed snack with nuts.
Move regularly. Regular physical activity, including moderate movement and strengthening exercises, can fit into a healthy routine. Walking, swimming, or cycling at a pace that lets you talk can count as moderate activity. Avoid pushing through exhaustion. Excessive endurance training may affect hormone levels and sperm quality.
Weight loss may help if you’re overweight. Observational data show overweight men are 11% more likely and obese men 42% more likely to have low sperm count. Talk with your GP or an accredited dietitian before making a major change, especially if you have a health condition. Aim for gradual progress you can keep up.
For more detail on the food and activity changes, see our sperm health tips for men. Treat them as a starting point, not a promise of a higher test result.
Stop Smoking and Reduce Heavy Alcohol Use
Quitting smoking and cutting back on heavy drinking are clear actions to discuss when you want to improve sperm health. These changes support your general health too.
Smoking is linked with lower sperm count, less semen, and poorer sperm movement. Even light smoking can affect sperm quality. If you smoke, ask your GP for help with a quit plan. Set a date and talk through what tends to trigger a cigarette. A plan that fits your routine is more useful than relying on willpower alone.
Heavy or daily alcohol use can affect semen quality and hormone levels. The exact amount that affects fertility isn’t clear, so don’t treat a specific drink limit as a guarantee of safety. If you drink heavily, ask your GP how to cut back safely. Some people need medical support to stop drinking.
Sperm take about three months to develop, so changes made now may take time to show in a test. Read guidance on sperm health for more on smoking and alcohol.
Don’t let a single slip convince you the effort has failed. Return to your plan, and tell your GP if quitting feels difficult.
Review Medicines, Steroids, Drugs, and Chemical Exposures
Some medicines and substances can affect sperm production or sexual function. Review them with your GP before making changes.
Bring the names of all prescription medicines, over-the-counter products, and supplements to your appointment. Long-term use of opioid pain medicines may affect fertility. Some medicines for depression or anxiety can also have an effect. Cancer treatments may affect sperm production as well. Your doctor can explain your options and whether timing or another treatment needs consideration.
Anabolic steroids can lower fertility and may have lasting effects on sperm count and quality. If you use them, be open with your GP. Don’t replace them with testosterone products bought online or without medical advice. Testosterone treatment can also interfere with sperm production.
Tell your GP about recreational drug use too. You can discuss it without guessing which substances matter or stopping something abruptly. If you’re worried about privacy, ask the clinic how your health information is handled.
At work, follow safety rules when handling pesticides, herbicides, heavy metals, or other chemicals. Use the protective gear your workplace requires. At home, reduce contact where it’s easy to do so, but don’t blame yourself for every exposure.
Keep a short written list of exposures or products you’re concerned about. It will help your GP focus the discussion.
Address Infections and Choose Comfortable, Breathable Underwear
Untreated sexually transmitted infections can harm reproductive health, so get tested if you may have been exposed. At the same time, choose underwear that feels comfortable and doesn’t trap excess heat.
Chlamydia and gonorrhoea can damage reproductive organs and affect fertility. Some infections cause no clear symptoms. If you have a possible exposure or symptoms, ask your GP about screening and treatment. Don’t wait for discomfort to become severe. Prompt care can also reduce the chance of passing an infection to a partner.
Heat is another factor worth managing. Avoid keeping a hot laptop on your lap for long stretches. Take a break from prolonged sitting, and skip frequent hot baths or saunas while you’re trying to conceive if heat exposure is a concern. These are low-cost habits, but they can’t diagnose or treat a medical cause of low sperm count.
Underwear shouldn’t squeeze or rub. Try a breathable fabric and a fit that gives your scrotum room to sit comfortably. SLY Collective Underwear’s Bamboo Hammock Pouch is designed with space and support, but underwear hasn’t been shown here to raise sperm count. There’s no independent study provided to confirm that this product improves fertility.
If your current pair rides up or causes chafing, changing the fit may make the day more comfortable. Our underwear and lifestyle guide explains what to consider without treating underwear as a fertility treatment.
Be Cautious With Supplements and Set Realistic Expectations
Supplements are not a shortcut to a higher sperm count. Evidence for many male fertility supplements is limited, and taking more than you need can cause harm or interact with medicine.
Start with food and a GP review. If a blood test or health concern points to a nutrient gap, your doctor can advise whether a supplement makes sense. Don’t copy a dose from a social post or combine several products because their labels sound persuasive. Keep the packaging or a list of ingredients so your GP can check what you’re taking.
Evidence for male fertility supplements is poor. Ask what evidence supports a supplement and whether it suits your health.
Give lifestyle changes time. Sperm take about three months to develop, so a test taken next week won’t reflect a full cycle of changes started today. Your GP can advise when to repeat the test. Results may not improve if a medical condition, blockage, or other factor is involved. That’s why a follow-up test and clinical review matter more than guessing from how you feel.
Keep the plan manageable. Pick a few changes you can sustain, then review progress with your doctor instead of adding a new product each week.
Frequently Asked Questions
How long does it take to increase sperm count?
It often takes around three months for lifestyle changes to show in sperm development. That’s because sperm take about that long to develop. A semen analysis sooner may still be useful as a baseline, but ask your GP when to repeat it. The time needed can vary, especially when an underlying health issue needs treatment.
Can food increase sperm count?
A nutrient-rich diet may support sperm health, but no single food can promise a higher count. Choose varied whole foods with fruit and vegetables, and include sources of omega-3 fats. Foods with antioxidants and nutrients such as zinc and selenium are also part of a balanced diet. Ask a GP before using supplements to correct a suspected deficiency.
Does underwear affect sperm count?
Underwear may affect comfort and heat around the scrotum, but there’s no independent evidence here that a specific style increases sperm count. Choose a breathable, comfortable fit that doesn’t squeeze or chafe. If a test shows a low count, don’t rely on underwear alone. Ask your GP about medical causes and next steps.
How many days should I abstain before a semen analysis?
Follow the collection instructions from your testing laboratory. Some guidance uses two to five days without ejaculation before collection, but the lab may give different directions. The point is to collect the sample under the conditions they specify. If you’re unsure, ask before your appointment so you don’t need to repeat the test.
Conclusion
Start with a semen analysis and a GP review, then choose a few changes you can keep up for about three months. If comfort is part of your plan, explore SLY Collective as an underwear option, not a proven fertility treatment.
