The maximum limit of exposure to<unk>  is around 45 °C, which causes the coagulation of intracellular proteins on living cells. However, exposure above 41 °C for short periods of time may be used, as has been the case for scientific studies on the effect of hot baths. In the case of artificial cryptorchidism or thermal insulation of the testicles, the use of a temperature close to that of the body (37 °C) has made it possible to increase the time of exposure in order to slow down the spermatogenesis process over longer periods, 4 years in a row at most. To date, only a decrease in testicular volume by a few percents has been observed during the contraceptive period. There is no evidence of an increased risk of testicular torsion. However, it has been shown that the nuclear quality of the spermatozoa was altered during the phase of inhibition of the spermatogenesis, but that this was reversible 3 months after the subject stops practicing artificial cryptorchidism. This finding should be taken into account when using this contraception method, during the inhibition phase and for 3 months after treatment discontinuation.
