现已知促性腺激素在滤泡期的分泌对将来的黄体分泌功能有重要影响.另外,FSH对成熟滤泡的破裂起决定性作用.在排卵前夕,卵巢分泌的甾体激素对促性腺激素分泌的作用特别重要.在滤泡期卵巢仅分泌很少的孕酮,加上肾上腺分泌的孕酮及外围△_5孕烯醇酮转变的孕酮,血流中孕酮量不超过0.6ng/ml.但在排卵前LH高峰初期,约在LH开始上升后6～9小时,血孕酮即上升.当LH达高峰时,血孕酮量为1ng/ml,排卵前上升的孕酮主要由成熟滤泡分泌,因在滤泡液中
It is known that the secretion of gonadotrophins in the follicular phase of the future luteal secretion has a significant impact.In addition, FSH rupture of mature follicles play a decisive role in the eve of ovulation, ovarian secretion of steroid hormone secretion of gonadotropin Is particularly important in follicular ovarian secretion of only a small progesterone, coupled with the adrenal secretion of progesterone and peripheral △ _5 pregnenolone progesterone conversion, blood progesterone does not exceed 0.6ng / ml However, during the early peak of LH before ovulation, blood progesterone rises about 6 to 9 hours after LH begins to rise, and when LH reaches its peak, the amount of blood progesterone is 1 ng / ml, and the progesterone rising before ovulation mainly consists of mature Follicular secretion, because in the follicular fluid
