人的性周期为一个月左右,每次只排一个卵。通过对猴的性周期的激素动态观察,其结果与人相似,故研究人类卵巢生理机能时;通过人或猴进行是合乎情理的。本文就人类从卵泡发育到排卵的机制结合动物试验加以叙述。一、从人的原始卵泡到排卵,各卵泡的形态特征及其对促性腺激素的感受性。成年妇女的卵巢中,可见到从原始卵泡到成熟卵泡的不同发育阶段的卵泡。也有表现卵泡变性、崩溃的闭锁卵泡。人类卵泡的形态如图1。摘除垂体的妇女,卵巢中只能看到大发育卵泡,(200～300μ),故认为其后的各种卵泡的发育要依赖促性腺激素(Gn)的存在。
Human sexual cycle is about a month, each row only one egg. By observing the hormonal dynamics of the monkey’s sexual cycle, the results are similar to those of humans, so it is reasonable to study human ovarian physiology when performed by humans or monkeys. This article describes the mechanism of human development from follicular to ovulation combined with animal experiments. First, from the human primordial follicle to ovulation, the morphological characteristics of follicles and their sensitivity to gonadotropin. Ovaries in adult women can be seen from the primordial follicles to mature follicles at different stages of development follicles. There are also manifestations of follicular degeneration, collapsing follicles. The form of human follicles in Figure 1. In women with pituitary gland removal, only the large developing follicles are seen in the ovary (200-300μ). Therefore, the development of various follicles thereafter is dependent on the presence of gonadotropin (Gn).
