The patient, female, 26 years old, was infertile after 2 years of marriage. Menstrual disorder with normal cycle of 30 days, lasting up to 12 days. Last menstruation: 2011-10-10. Previous self-tested temperature for 4 months, BBT biphasic for 2 months and irregular for 2 months. The bilinear type of temperature was taken when taking menstrual regulation herbs and the duration of high temperature phase was less than 10 days. The sex hormone test on the third day of menstruation was basically normal. Male side examination is normal. Luteal insufficiency can be divided into luteal insufficiency and luteal atrophy insufficiency. The diagnosis can be confirmed based on basal body temperature, blood progesterone measurement and endometrial biopsy. In these patients, the basal body temperature is biphasic, but rises and falls slowly, with a rise of less than 0.3°C and lasts only 9-10 days, sometimes with a prolonged follicular phase. On the 21st or 22nd day of menstruation, the blood progesterone is less than 10ng/ml. If an endometrial biopsy is done at this time, the endometrial phase is less than normal for more than 2 days. If an endometrial biopsy is done on the first day of menstruation it may indicate hypersecretion. The most common treatment for luteinizing insufficiency is to supplement the progesterone deficiency in the body, generally with progesterone intramuscular injection and progesterone oral, and also with chorionic gonadotropin (hCG) to promote luteal function.
