Are boxers really better than briefs?

There is still much debate over whether the type of underwear a man wears makes a difference in the quality of their sperm; however, research seems to have found the answer.

There’s a reason why the testes are located outside the body, this is to keep them below body temperature, so they do not overheat. The human body is approximately 37 degrees Celsius and in order to produce healthy sperm, the testicles need to hang outside the body to keep them on average about two degrees cooler than the rest of the body.

Heat and sperm do not mix, in fact studies out of Harvard have revealed that increased scrotal temperatures were directly linked to reduced testicular function and sperm quality.

One study published in 2018 revealed that men who wore loose fitting underwear had a sperm concentration 25% higher than those who wore tight fitting underwear. Additionally, looser fitting underwear led to 17% higher total sperm count and a 33% higher motile count compared to the men who wore tighter underwear.

So, are boxers really better for sperm quality than briefs? The research has suggested that underwear choice does make a significant difference.

FAQs about improving natural fertility

Will stress affect my ability to get pregnant?

Yes, chronic stress can impact fertility by disrupting hormonal balance and ovulation patterns. Managing stress through relaxation techniques, regular exercise, adequate sleep, and mindfulness practices may help optimise your chances of conception. Consider speaking with a counsellor if stress feels overwhelming.

How does my partner's health affect our fertility?

Sperm health accounts for about 40% of conception challenges. Your partner can improve sperm health by maintaining a healthy weight, avoiding excessive heat exposure (hot tubs, saunas, tight clothing), limiting alcohol, quitting smoking, managing stress, and taking a multivitamin with antioxidants. Sperm takes about 3 months to develop, so lifestyle changes need time to show results.

When during my cycle am I most fertile?

Your fertile window typically spans 5-6 days, ending on ovulation day. For a regular 28-day cycle, this usually falls between days 10-15, with peak fertility 1-2 days before ovulation. Track your cycle using ovulation predictor kits, basal body temperature, or cervical mucus changes to identify your unique pattern. Having intercourse every 1-2 days during this window optimises your chances.
