Scrotal temperature is increased in disposable plastic lined nappies

Abstract

Scrotal hypothermia is an important factor for normal spermatogenesis. This study shows that scrotal temperature, which closely reflects testicular temperature, is increased in boys wearing disposable plastic lined nappies. The physiological testicular cooling mechanism is blunted and often completely abolished during plastic nappy use. The present results establish the basis for further research on the impact of increased testicular temperature in infancy on later spermatogenesis.
