Elevation of testicular temperature may result in arrest of spermatogenesis, abnormal semen parameters and sterility.
It has been proposed that brief style underwear may produce scrotal hyperthermia and lead to clinical subfertility.
Although this idea is regarded as dogma by many in the lay community and the changing of underwear type is a therapy frequently recommended by medical practitioners, there is a paucity of data measuring scrotal temperature as a function of underwear type.
Scrotal, core and skin temperatures were measured in 97 consecutive men presenting for evaluation of primary clinical subfertility.
These cases were categorized by underwear type to boxer or brief group.
Semen analyses were obtained in all patients.
Individuals from each group were compared to ascertain differences in temperature when wearing and not wearing underwear.
Baseline semen parameters also were compared.
In 14 subjects (crossover group) underwear type was changed to the alternative type and scrotal temperature measurements were repeated.
Literature regarding underwear type, testicular temperature and/or fertility was reviewed and critically analyzed.
Mean scrotal temperature plus or minus standard deviation was 33.8 ± 0.8C and 33.6 ± 1.1C in the boxer and brief group, respectively.
There were no significant temperature differences between the groups. (...)
