Trying to conceive? The day-to-day habits you can change are a sensible place to start. For how to keep sperm healthy, focus on food, movement, smoking, alcohol and heat, while getting medical advice if pregnancy hasn’t happened after a year of trying.
Understand the factors that affect sperm health
Sperm health isn’t one number. A semen test can assess how many sperm are present, how well they move and whether their shape looks typical. These measures are called count, motility and morphology. A result outside the reference range doesn’t by itself explain whether you can conceive, so a clinician needs to read it in context.
Daily habits can affect fertility, but they aren’t the whole story. Hormone conditions, testicular problems, past infections, some medicines and other health issues may also play a part. You can work on habits while arranging a check-up, rather than assuming the cause is something you can fix with clothing or food alone.
Start with a short review of your routine. Note how often you smoke or drink, how much time you spend sitting, and whether hot baths or a laptop on your lap are regular habits. Also make a list of prescription medicines and supplements. Don’t stop a prescribed medicine on your own. Ask your GP whether it could affect fertility and what to do next.
A balanced eating pattern is a good base. Australian guidance recommends a healthy range of foods, including fresh fruit, vegetables and lean meats. Foods that contain zinc, folate and antioxidants can fit into that pattern, but no single food can guarantee conception. You can also read our guide to habits that support sperm health for more ways to build a steady routine.
Sleep and stress deserve a place on the list too. Aim for a regular sleep schedule and make room for a daily walk, a quiet break or another activity that helps you unwind. These steps support general health. They don’t replace an assessment if you have a known fertility concern.
Build healthy habits with movement and weight management
Movement supports general health and can help you work toward a healthy weight. Obesity in men is linked with lower fertility, in part through hormone changes and related health problems. Aim for at least 30 minutes of moderate activity.
Make the plan easy to repeat. Walk briskly after work, cycle at a pace that lets you talk, or garden for half an hour. If you sit at a desk, stand up and move during breaks. The goal is a routine you can keep, not a punishing burst of training followed by weeks on the couch.
If you’re carrying extra weight, avoid crash diets. Choose regular meals built around vegetables, fruit, whole grains and a suitable protein source. A GP or dietitian can help you set a safe plan, especially if you have a health condition or take medication. Weight is only one part of fertility, so don’t treat the scales as a diagnosis.
Exercise doesn’t need to mean hard training every day. Start at a level that fits your current fitness, then add time or pace gradually. If a workout leaves you exhausted or sore for days, ease back. A steady brisk walk still counts. The point is to make activity part of the week, not to chase a perfect program.
Keep it sustainable. Pick a time and activity you’ll actually do, then build from there. If pain, dizziness or another symptom shows up, stop and check with a health professional.
Quit smoking and reduce alcohol
Smoking can lower sperm quality, including count and movement. It can also damage sperm DNA. If you smoke, make a quit plan and ask your GP about support.
Second-hand smoke matters too. Keep your home and car smoke-free, and ask people around you not to smoke near you or your partner. If quitting feels difficult, that doesn’t mean you’ve failed. Talk with a health professional about a plan that suits your situation.
Alcohol can affect sperm quality, libido and erections. If you’re trying for a baby, avoiding alcohol is the safest course. At a minimum, avoid binge drinking. Cutting back can be a useful first move, but speak with a clinician if you drink heavily or feel you may have trouble stopping. Suddenly stopping heavy alcohol use can be unsafe without medical support.
Don’t overlook vaping or recreational drugs. Evidence and effects can vary by substance, but recreational drug use may affect fertility. Tell your GP what you use, including cannabis, so they can give advice based on your health and plans. Be frank. They’re there to help, not to score points.
Write down a quit date or a change you can make this week. For example, you might remove cigarettes from the house or plan alcohol-free days. Then check in with your GP if the plan isn’t holding. A clear next step beats a vague promise to “be healthier.”
Choose breathable underwear and avoid excess testicular heat
Testicles sit outside the body partly because sperm production works best below core body temperature. Long periods of heat around the groin may affect sperm production. Don’t panic over one hot bath, but notice repeated heat exposure if you’re trying to conceive.
Cut down on frequent hot baths, saunas and hot tubs for now. Keep laptops on a desk rather than your thighs, and turn off heated car seats when you don’t need them. If you sit for long stretches, get up and move now and then. These are simple changes that reduce avoidable heat without turning your day into a temperature-monitoring exercise.
Underwear should feel comfortable and let you move. If tight briefs leave you hot or compressed, try a roomier, breathable fit. SLY Collective Underwear makes bamboo pouch styles designed to give the scrotum space and support. That’s a clothing choice, not a proven fertility treatment. There’s limited evidence that a specific underwear style improves the chance of conception.
Our guide to underwear and sperm health explains what to consider when choosing a fit. Look for comfort and airflow. If you wear a pair all day, it shouldn’t pinch or leave you feeling overheated. You don’t need special cooling gear or ice baths to take sensible steps.
Cold showers and ice baths aren’t proven fertility fixes. Cold may reduce heat exposure, but that doesn’t mean more cold is better. Don’t put ice directly on the scrotum or use an extreme routine based on online claims. If you’re concerned about swelling, pain or a change in a testicle, see a doctor rather than trying to cool it away.
Time conception attempts and know when to seek advice
Timing intercourse around ovulation can help you make the most of each cycle. The fertile window is the five days before ovulation and the day ovulation occurs. The timing changes with the menstrual cycle, so your partner may use cycle signs or tracking to estimate it. Regular sex during that window is a reasonable approach.
You don’t need to have sex every day if that adds stress. If tracking becomes a chore, step back and talk with your partner about a routine that feels manageable. Fertility is shared. Both partners may need assessment, and focusing only on sperm can miss other factors.
Some lubricants may not be suitable when trying to conceive. If you need one, ask a pharmacist or GP about products designed for use when trying for a baby. Don’t assume that a product marketed as natural or gentle has been tested for sperm compatibility.
Speak with your GP if you’ve been trying for 12 months without pregnancy. Seek advice sooner if you have a known reproductive condition, previous testicular injury or surgery, problems with erections or ejaculation, or a concern about a medicine. A clinician can review your health and arrange a semen analysis or other tests where needed.
Age can matter for men as well, though its effect is less marked than the effect of age on female fertility. If you’re worried about age, treatment options or sperm storage, ask a fertility specialist what applies to you. Don’t rely on a supplement stack or an online test to answer a medical question.
A GP can help decide what tests make sense and refer you if needed. Bring your medication list and any test results to the appointment.
Conclusion
Start with the changes you can keep: move regularly, eat balanced meals, avoid smoking, limit heat and discuss alcohol if you’re trying to conceive. Pick one change to begin this week. If you’ve been trying for a year without success, book a GP appointment rather than waiting for lifestyle changes alone to solve it.
Frequently Asked Questions
How long does it take to improve sperm health?
Changes may take a few months to show in new sperm, so don’t judge a lifestyle change after a few days. Smoking cessation guidance suggests allowing about three months before trying to conceive. Results vary, and a semen analysis can only be interpreted by a health professional alongside your medical history.
Does underwear affect sperm health?
Underwear may affect comfort and heat around the testicles, but a particular style hasn’t been proven to guarantee better fertility. Choose a fit that doesn’t squeeze or trap heat. Breathable pouch underwear, including styles from SLY Collective Underwear, is one option for comfort, not a substitute for medical care.
Should I take supplements to improve sperm quality?
Don’t start high-dose supplements without advice. A balanced diet is a sensible first step, and supplements may be useful in some cases, such as when a clinician identifies a deficiency. Tell your GP about everything you take, since supplements can interact with medicines or be unsuitable for your health.
When should I see a doctor about male fertility?
See your GP if you and your partner have tried to conceive for 12 months without success, or sooner if you have a known reproductive issue or symptoms. Your doctor can review health factors and decide whether semen testing or referral is appropriate. Fertility concerns are a shared health issue, so both partners may need support.
