In tests of 30 male volunteers, Jung's team found that, on average, 90 minutes on a heated car seat raised the men's scrotal temperature enough to nearly match their core body temperature.
Normal sperm production is temperature-dependent and requires a testicular temperature that is slightly below the body's core temperature,You are not allowed to view links. Register or Login, the researchers explain in the journal Fertility and Sterility.

Heated car seat may be too hot for men
Heated seats are a luxury in some cars, but they may be a little too hot for men, a preliminary study suggests.
Researchers found that 90 minutes on a heated car seat created a significant increase in men's scrotal temperature. Because heat stress on the testicles has been shown to impair sperm quality, the findings raise the possibility that over time, heated car seats could affect a man's fertility.

Register or Login, on its own, raises a man's scrotal temperature, and the effect of a heated car seat is actually weaker by comparison, according to the researchers.

According to Jung, studies should now directly examine sperm quality to see if there is, in fact, a risk from heated car seats.
