Abstract

In estrogen-induced cryptorchidism in mice, differentiation of the epididymis is arrested. Transformation of the Wolffian duct into the epididymis, which is androgen dependent, is incomplete. Simultaneous administration of estrogen and HCG prevents cryptorchidism, and the appearance of the epididymis in the transmission and the scanning electron microscope is similar to the appearance of the epididymis of control animals. According to our studies the epididymis differentiation is a prime mover in a process which leads to the descensus of the testis.

妊娠期接受雌激素的雄性小鼠附睾的透射电镜和扫描电镜。
在雌激素诱导的小鼠隐睾症中,附睾的分化被阻止。沃尔夫管向附睾的转化是不完全的,附睾是雄激素依赖性的。同时给予雌激素和HCG可预防隐睾,透射电镜和扫描电镜下的附睾外观与对照动物的附睾外观相似。根据我们的研究,附睾的分化是导致睾丸下降过程的原动力。
