9 things your guy is doing that are lowering his sperm count – Today’s Parent

Exposure to heat is known to affect sperm production. Saunas, hot tubs and even heated car seats are all culprits, but one of the most common sources of heat is laptops. “Laptop computers can literally cook the sperm,” says Baratz. Occasional use isn’t a problem, but working with a laptop on his lap all day or every day can affect sperm, says Dunne. Give him a pillow or tabletop to place his computer on instead. It’s also worth noting that certain occupations that involve heat, such as working as a chef in a hot kitchen or as a firefighter in a non-breathable uniform, can have a negative effect on sperm count.
