目前我们对生殖生理上的很多问题还不能了解清楚,例如月经周期中,在FSH分泌增加的影响下,约有500个滤泡发育,并趋向成熟,为何只有一个能完全成熟排卵,而其余则变成闭锁滤泡,又如促性腺激素高峰时,为何全部卵母细胞不能都进行减数分裂?对于滤泡一旦破裂后,颗粒层细胞在形态上与功能上都突然成熟,怎样来解释?最后,当促性腺激素的分泌并未改变,黄体溶解又是什么原因引起的? 当人们在卵巢中,尤其是在滤泡水平发现了控制素后,这些疑问初步得到解释,控制素是组织产生的一种物质,可以对组织本身的功能,通过抑制性机制进行控制,所以
At present, we do not understand many reproductive physiology issues. For example, during the menstrual cycle, about 500 follicles developed and tended to mature under the influence of increased FSH secretion. Why was only one fully mature ovulation? Into the atresia follicles, and if the peak of gonadotropin, why all oocytes can not all meiosis? Once the follicle rupture, the granular layer cells in the morphology and function of a sudden maturity, how to explain? Finally, when the secretion of gonadotropin has not changed, what is the cause of corpus luteum? These questions are tentatively explained when one finds out that in the ovary, especially at the follicular level, the control hormone is produced by the tissue A substance that can control the function of the organization itself through inhibitory mechanisms, so
