Semen quality - Wikipedia

Although you might think infertility in a couple is usually a problem in the female partner, about 1 in 3 cases are due to infertility caused only by a problem in the man. Normal sperm production requires the scrotum to have a slightly lower temperature than the rest of the body. When 1 of several possible conditions raises the temperature, it can increase a man's risk of becoming infertile. The fetal testis develops in the abdomen, but eventually moves into the scrotum, where it is normally located at birth. Scrotal temperature is about 2 degrees Fahrenheit lower than in the rest of the body. This temperature in required for the process of sperm development, or spermatogenesis, to proceed normally.

In specimens of semen kept at 37 degrees C sperm lose their motility and viability. If kept at 4 degrees C they retain their viability but lose their motility from so-called thermal shock. The best temperature to keep semen in order to preserve sperm motility is 20 degrees C. Loss of motility at 37 degrees C is not entirely prevented by prevention of bacterial contamination with antibiotics. PIP: Semen specimens were obtained from 42 fertile men requesting voluntary vasectomy and stored at 4, 20, and 37 degrees C.
