Comparative effect of x-ray and ultrasound (inducing hyperthermia) on the testes of rats--a rationale for male castration by ultrasound.
The testes of rats were treated by x rays, or ultrasound. 2000 rads single dose of x ray led to tubular atrophy, which was defined as destruction of all spermatogenic cells but Sertoli cells. Ultrasound of 1 W/cm2 for 15 min led to tubular necrosis, which was designated as complete disorganization of the seminiferous tubules with disappearance of spermatogenic as well as sertoli cells. The possibility of male castration by ultrasound is raised.
