Low corpus luteum will be clinically manifested as shortened menstrual cycle or irregular vaginal bleeding at the end of menstruation. It needs to be adjusted clinically, and in serious cases, it may lead to infertility. It is recommended to take oral progesterone for treatment after ovulation, two capsules/day for 10 days, and menstruation will occur 3-7 days after stopping the drug. At the time of the next menstrual cycle, repeat the last treatment. Continuous use of the drug for 3 months can effectively regulate the insufficiency of luteal function. Women are also advised not to smoke or drink too much, to develop good living habits, not to stay up late, and to keep a good state of mind, which will also play a positive role in the adjustment of the endocrine system.
