relating to the part of a woman's monthly menstrual cycle after she has ovulated (= produced an egg), when her body produces a hormone that is important if she becomes pregnant

The luteal phase begins after ovulation and ends when you get your next period. 黄体期从排卵后开始，到下次月经来时结束。

In this condition, the ovaries do not produce enough luteal hormone. 这种情况下，卵巢分泌的黄体激素不足。
