Abstract

Male fertility is a very important but often neglected area in medical practice. Compared to what is available on female subfertility, there is a dearth in research on male fertility. Fertility in male depends on the normally functioning hypothalamopituitary gonadal axis, normal testis and the environment necessary for viable, motile sperm production. The production of healthy germ cells require a temperature which is slightly below the core body temperature and there are several temperature regulatory mechanisms in humans that ensure the maintenance of the scrotal temperature several degrees lower. The aim of the present review is to synthesise and summarise the literature available on scrotal temperature regulation in the healthy male and to recapitulate the disease conditions, environmental, occupational and lifestyle factors that affects scrotal temperature and thus male fertility.
