Luteal insufficiency means that after ovulation, the corpus luteum is not fully formed, causing insufficient secretion of progesterone, which leads to the endometrium not being converted in time, and a series of symptoms may occur. Generally, in adolescent women, if luteal deficiency occurs, it will manifest as spotting bleeding symptoms during ovulation or in the middle and late stages of ovulation, or it will shorten the menstrual cycle, which can be treated with estrogen and progesterone supplementation. If luteal deficiency occurs during the fertile period, it will easily lead to miscarriage or embryonic abortion. Usually, endocrine tests are done after the problem occurs and the luteal deficiency is found to be the cause of the problem. In middle-aged women with luteinizing insufficiency, progesterone treatment can be used after examination and clarification. Usually, we should pay attention to keep our spirits happy, avoid tension, pay attention to personal hygiene, avoid infections and do not eat cold, spicy and stimulating foods to prevent luteal deficiency.
