Exposure of rat testes to high-frequency sound waves temporarily interrupted the spermatogenic process. Rats treated with 1 watt/sq cm for 10 minutes exhibited a degeneration of advanced germinal cells and were incapable of impregnating females for 150 days. Forty-eight hours after sonication, spermatocytes and spermatids developed irregular membranes and released their contents into theinterstitium. Spermatogonia, Sertoli cells, and Leydig cells appeared normal, and no genetic anomalies could be detected in the progeny of treated animals. It was hypothesized that the reduction in sperm count was due to changes in membrane permeability which produced conditions unfavorable to maturation of testicular cells.
将大鼠睾丸暴露于高频声波会暂时中断生精过程。用1瓦/平方厘米处理10分钟的大鼠，其晚期生殖细胞出现退化，并且在150天内无法使雌性受孕。超声处理48小时后，精母细胞和精子细胞的细胞膜出现异常，其内容物释放到间质中。精原细胞、支持细胞和间质细胞看起来正常，在接受处理的动物后代中未检测到遗传异常。据推测，精子数量减少是由于膜通透性的改变，从而产生了不利于睾丸细胞成熟的条件。
