月经周期中黄体期特征为黄体分泌孕酮(P)而P的产生取决于促黄体与溶黄体因子间的精细平衡。除LH外,正常黄体功能还与PRL有关,过高过低均可使P分泌减少。由于黄体来自排卵后的卵泡,因之,从新卵泡、发育,进而与促性腺激素及GnRH均有相关。黄体功能不全(简称为LPD)主要为黄体的P分泌不足,亦可因靶器官(如子宫)对孕酮反应降低所致。LPD不是一种单一病变,多种原因通过同一途径均 The luteal phase during the menstrual cycle is characterized by progesterone (P) secretion by the corpus luteum and the production of P depends on the fine balance between luteinizing and lutealizing body factors. In addition to LH, normal luteal function is also associated with PRL, too high and too low P secretion can be reduced. Since the corpus luteum comes from the follicle after ovulation, it develops from the new follicle, and then it is related to gonadotropin and GnRH. Luteal phase dysfunction (referred to as LPD) is mainly due to the lack of P secretion of the corpus luteum, but also due to decreased target organ (such as the uterus) progesterone. LPD is not a single disease, for many reasons by the same route
