What is the ideal temperature for sperm production?

.What is the ideal temperature for sperm production? The sperm production is best when the temperature is approximately 93.2 F (34*C). This is 5.4"F (3’C) lower than that of the average body temperature of 98.6’F (37*C). However, your testicles might get too chilly for optimal sperm production. Cold temperatures induce the scrotum and testicles to move upward toward the body.
