Sperm crisis under high temperatures and reproductive health protection for those who work while driving
Winter is here, and taking a hot bath or sauna is a pleasant experience. However, inappropriately high temperatures can seriously damage the testicles, a man's most important organ. Sperm are produced in the testicles and have strict temperature requirements, needing a constant temperature of 34-35°C to develop normally. Sauna water temperatures are much higher than this, which is extremely detrimental to sperm growth or can cause excessive sperm death, leading to infertility. A significant proportion of male infertility cases are due to testicular temperatures exceeding normal levels.
Sperm cannot survive when the temperature exceeds 2-3°C. Prolonged high temperatures primarily affect spermatogenic cells, causing irreversible damage to fertility, and can even affect the testicular interstitial cells that produce androgens, subsequently impacting male sexual function. Men who have not yet fathered children should not prioritize this comfort. According to recent research, men who professionally drive are more prone to infertility. Driving raises scrotal temperature, and high temperatures negatively impact sperm formation in the testes. Past studies have found that men who make a living by driving have lower sperm counts.
Increased scrotal temperature during driving may be a significant contributing factor to decreased fertility in professional drivers. Male drivers who have not yet fathered children should take extra care to protect themselves. Wear loose-fitting cotton underwear for good ventilation; adjust your underwear according to the temperature while driving; and take breaks and move around frequently during long drives. Avoid prolonged driving for three months before planning a pregnancy, and do not wear jeans while driving. Similarly, for those who sit for long periods in an office, choose a wooden chair and stand up for fresh air every half hour to an hour.
Laptops are a potential "fertility killer." Laptops generate a lot of heat, and since the knees are close to the male genitals, this can create a small, localized high-temperature environment that raises scrotal temperature. Studies show that using a laptop on your knees can raise scrotal temperature by 2.1°C from the thighs and an additional 0.7°C from the computer itself. People who frequently use their knees to support their laptops are often those whose work requires this or who have made it a habit, resulting in a high-density, prolonged "baking" of the genitals. Over time, this will definitely reduce fertility.
Don't let underwear become a culprit for infertility. Studies have found significant differences in testicular temperature and plasma hormone levels between the pure polyester underwear group, the half-cotton, half-polyester blend group, and the pure cotton group. Polyester underwear can temporarily inhibit sperm production. Polyester can also generate an electrostatic field in penile tissue, which may explain why men who wear polyester underwear for a long time experience decreased sexual function. Current men's underwear designs treat the scrotum and penis equally, tightly wrapping them in double layers of fabric and pressing the testicles tightly against the perineum.
When the scrotum is confined to a narrow space for extended periods, it cannot expand and contract automatically, leading to poor ventilation and increased body temperature. This can cause sperm abnormalities, necrosis, and decreased motility within the scrotum. The solution is simple: health-promoting underwear with an opening in the crotch area is beneficial for men's health. The scrotum is exposed outside the underwear, allowing for ample ventilation and heat dissipation. Regarding underwear material, pure cotton may not be the best choice for men who sweat a lot. While pure cotton underwear absorbs sweat, it doesn't dry easily. Currently available underwear made of Korean silk fabric has excellent absorbency. Another good option is modal fabric, which has higher absorbency and wicking properties than regular cotton.
