本文研究了18例妇女自然周期中的各种排卵标志(超声波测量卵泡直径、E_2、孕酮和LH的测定)。病人分成两组:1组在同一个周期已受孕;2组显示卵泡生长的迹象,E_2和LH中期升高,但黄体期孕酮(P)水平低。另外,在近于最适的周期中,内分泌学和形态学的变化不同步。这些表现说明在成熟期末有卵泡闭锁的过程,正如在正常妇女中所见的那样。 In this paper, 18 ovulation markers of 18 women in their natural cycle (ultrasound measurement of follicular diameter, E2, progesterone and LH) were studied. Patients were divided into two groups: one group had been pregnant in the same cycle; two groups showed signs of follicular growth with elevated E_2 and LH mid-term but low progesterone (P) levels in the luteal phase. In addition, changes in endocrinology and morphology are out of sync in near-optimal cycles. These manifestations illustrate the process of follicle atresia at the end of maturity, as seen in normal women.
