Luteinized granulosa cells secrete inhibin, which inhibits the pituitary gland from making FSH.

黄素化的颗粒细胞会分泌抑制素，抑制垂体生成FSH。

Starting at puberty and continuing throughout life, sertoli and leydig cells don't produce inhibin and testosterone, respectively.

这种病变从青春期开始，将会持续一生；睾丸支持细胞和睾丸间质细胞不再分别产生抑制素和睾酮。

To maintain balance, or homeostasis, testosterone reduces gonadotropin releasing hormone and luteinizing hormone and sertoli cells release the hormone inhibin which inhibits release of follicle stimulating hormone.

为了保持多种作用平衡，即“稳态”，睾酮还会反作用于GnRH和LH，使它们减少；同时，睾丸支持细胞还会释放抑制素；抑制素也会抑制FSH的释放。

AFP, though, can be elevated by other conditions as well, so in order to get a more exact diagnosis, additional blood tests for human chorionic gonadotropin, or HCG, inhibin A, and estriol, as well as an ultrasound are usually done.

但甲胎蛋白也会由于不少其它原因而升高，所以为了得到更准确的诊断，还需检查人绒毛膜促性腺激素（HCG）、抑制素A、雌三醇水平，或作超声检查。
