The relation between daily activities and scrotal temperature (original) (raw)

Twenty-four-hour monitoring of scrotal temperature in obese men and men with a varicocele as a mirror of spermatogenic function

Human reproduction (Oxford, England), 2015

How do day and night scrotal temperatures, spermatogenesis parameters, sex hormones and intratesticular perfusion in obese men and men with a varicocele compare with healthy controls? Compared with healthy controls, 24-h monitoring of scrotal temperature in men with a varicocele and obese men showed higher temperatures and this condition was related to a significant alteration of spermatogenesis and stasis of testicular perfusion. Several studies have shown that increased scrotal temperature has dramatic effects on spermatogenesis. Scrotal hyperthermia by exposure to sauna is able to induce a significant alteration of sperm production. In a case-control study, data were collected over a period of 2 years from 60 subjects with risk factors for testicular heating and 20 healthy subjects who consecutively attended an andrology unit as participants in an infertility prevention program. Forty subjects with a left varicocele, 20 obese men and 20 healthy subjects who served as controls, we...
