Unproven Male Fertility Methods: Experts Warn of Risks
Social media is rife with unverified advice on boosting sperm quality, but experts caution that such practices can be dangerous and recommend relying on proven lifestyle changes.

As concerns about declining male fertility grow, social media hashtags like #malefertility and #semenanalysis promote various unproven methods to improve sperm quality. Many men, such as 28-year-old Simon from Miami, start their day with a sauna and ice packs on their groin, follow strict diets, and wear cotton underwear to protect their fertility. However, medical experts say such measures have minimal impact and may even be harmful.
While environmental pollutants and testicular overheating can affect sperm quality, specialists emphasize that the most significant improvements come from quitting smoking, losing weight, and increasing physical activity. Professor Channa Jayasena from Imperial College London warns that taking fertility medications without medical supervision can cause blood clots, breast growth, and other serious side effects.
Influencers like Bryan Johnson, who claims to have four times the average sperm count, promote saunas and ice packs without scientific backing. Others advocate donating blood to "filter out" microplastics or red light therapy – all unproven. Global birth rates have declined from 4.9 children per woman in 1950 to 2.2 in 2025, but experts note the causes are multifaceted, including financial, environmental, and political factors. The decline in sperm count is real, but its causes remain unclear, with some studies showing no drastic drop.
Men like Jamal, who used steroids and testosterone and then turned to online forums for fertility advice, often receive unprofessional recommendations. After consulting an endocrinologist, Jamal discontinued all medications and hopes for recovery. Experts urge men to consult physicians rather than following social media influencers.
