问个事儿，有没有可能sex hormones分泌降低，反而fertility增强啊？比如follicule
recruitment啊什么的。谁有这方面的paper啊？
看了几篇review，不得要领。

That's really depends on what kind of sex hormone (Estrogen, progesterone or
Testosterone) and when the reduced level occur(in utero? prenatal? pubertal
? during pregnancy?)
Besides, sometimes it is ratio of two sex hormones (e.g Estrogen/
progesterone) that determines the fertility
Your question is too general to answer
Yet your assumption might be right in nature.

在proestrus期测的estrogen，FSH，LH，跟fertility有啥关系么？
没测progesterone啊，需要测这个么？什么时候测呢？

The hormone change during early pregnancy in mouse can be found in the link:

E2, FSH, LH is important for ovulation during proestrus (before ovulation)
and early luteinization (around ovulation).
What is your phenotype? more oocytes released during ovulation??? More
litters? More implantation Sites? More body weight after birth? Less
absorption sites during pregnancy? More easily to get plug??? All these
might be due to various factors and they might NOT indicate enhanced
fertility.~~!

我觉得很多人上来提问的时候问得也太保守了，一点点模棱两可的信息，看着我总觉得
被吊着半口气
其实稍微多说那么一点点别人也没法“偷”你的idea吧

FSH, LH, E2下降，但是litter size增加。
咋解释啊？
