体外受精-胚胎移植 (IVF-ET) 中控制性卵巢刺激 (COS) 使多个卵泡发育,从而获取多个卵母细胞和胚胎,提高妊娠率【1】。促性腺激素 (Gn) 中的卵泡刺激素 (FSH) 在卵泡选择和优势卵泡的发育过程中起重要的作用。在黄体末期,孕酮浓度的降低以及黄体产生的抑制素 A 的降低共同引起 FSH 水平继发性升高,是优势卵泡选...

FSH plasma levels (ng/ml, mean ± s.e.m.) at 4 weeks were 4.1 ± 0.4, 2.8 ± 0.3 and 1.7 ± 0.4; at 6 weeks, 4.5 ± 0.5, 2.3 ± 0.5 and 1.9 ± 0.6; and at 8 weeks, 3.1 ± 0.3, 2.1 ± 0.3 and 3.3 ± 0.4, for the Finn × Awassi, Assaf, and Awassi genotypes, ...
Additional transcription factors including AP1, SP1 and C/EBP family were also reported to contribute in the transcriptomics action of FSH [16, 98, 99]. FSH-induced PGE2 secretion is also an additional indirect effect that maintains the cAMP levels and stimulates the overexpression of the EGF-...
Many women with PCOS have high LH levels all the time. Since the uterus needs LH during the first few weeks of pregnancy, high LH levels tell the ovaries that there is pregnancy going on-even when there is not. This keeps eggs locked inside the ovaries, many of them encased in cysts....

Poor-quality eggs cannot generate the cellular energy required for the seven-day sprint from ovulation to implantation. There is a lack of function; it just can’t keep up. And it’s honest to communicate this to women with high FSH levels. Brutal but honest. And do the research. Given ...
If there are abnormally high levels of a hormone in the blood, feedback to the gland responsible for its production inhibits secretion. If there are abnormally low levels, the gland is stimulated to step up production and secretion. In this way a homeostatic balance is maintained. (See also ...
