ABSTRACT:
A male contraceptive device includes a resistive heating unit secured in an insulated scrotum sack. The heating unit is linked to a control unit by conductors. The control unit forms part of a carrying case worn at the user's waistline and which contains a power source, on-off switch, low battery indicator, defective element indicator, timer, beeper and telethermometer. The control unit and heating unit produce a significant increase in intrascrotal temperature which creates a suppression of spermatogenesis rendering the person temporarily sterile. The heating unit can be concentrated at the posterior end of the sack for quickly suppressing spermatogenesis in the human epididymis.
