The average time to pregnancy if a man is under 25 is just over four and a half months but nearly two years if a man is over There is a five-fold increase in the time it takes to get pregnant if the man is over Fact: Male infertility is not passed down genetically. However, there can be some hereditary conditions that may cause infertility. Fact: There is strong evidence that smoking unfavorably affects male fertility.

    Male infertility affects approximately one in every seven couples. It can be due to low sperm production, blockages or abnormal sperm function. There are a number of reasons that lead to male infertility and overheating of the testicles is considered to be one of the factors. Sperm production is highly sensitive to temperature changes and requires a temperature of degrees lower than the body temperature, for sperm production. The placement of the testes in the scrotum, away from the internal heat of the body is due to the same reason.

University of Oregon biologists have used a model organism to identify molecular mechanisms that produce DNA damage in sperm and contribute to male infertility following exposure to heat. In humans, the optimal temperature for sperm production is just below body temperature, in a range of about degrees F.
