Male infertility is present in up to half of all infertile couples. Therefore, it is very important that the male partner be evaluated early, prior to any female treatment(s).
Male infertility may have several causes. One common cause is elevation of temperature in the testes. The scrotum functions to heat and cool the testes by moving them closer to or further away from the body. Anything that interferes with this function can cause male infertility. For example, tightly fitting clothes elevate testicular temperature by not allowing the scrotum to move away from the body.
