Abstract
The pituitary gonadotrophins luteinizing hormone (LH) and follicle-stimulating hormone (FSH) were found to be higher in female rabbit fetuses from day 25 to day 32 of pregnancy. No difference was observed in pituitary gonadotrophins or serum LH in the neonatal males and females on days, 1, 6 and 13. Serum FSH concentrations were significantly higher in female than in male neonates. It is concluded that the rabbit fetal pituitary is capable of synthesizing gonadotrophins from day 25 of gestation.
摘要
研究发现，在怀孕第25天至第32天的雌性兔胎儿中，垂体促性腺激素促黄体生成素（LH）和促卵泡生成素（FSH）水平较高。在出生第1天、第6天和第13天的新生雄性和雌性兔中，垂体促性腺激素或血清LH水平未观察到差异。雌性新生兔的血清FSH浓度显著高于雄性。结论是，兔胎儿垂体从妊娠第25天起就能够合成促性腺激素。
