Several types of menstrual disorders

　　One is anovulatory Menstrual disorders , can be expressed as amenorrhea , oligomenorrhea, early menstruation, late menstruation, frequent menstruation (one menstruation every ≤20 days), etc., the menstrual period will also become longer or shorter. One is menstrual disorder with ovulation, which is characterized by dysfunction of the corpus luteum and incomplete atrophy of the corpus luteum.

　　Before menstruation, estrogen and progesterone levels decrease. Uterus When the endometrium cannot be maintained, it falls off, which is menstruation. The normal biphasic basal body temperature is as follows: before ovulation, the body temperature drops slightly, and then quickly rises to about 0.4°C higher than the original body temperature, which usually lasts for 14 days.

　　Luteal corpus luteum dysfunction. It is more common and manifests as a shortened luteal phase, less than 11 days, and the entire menstrual cycle is also shortened, sometimes only 21 days. This can be determined through basal body temperature monitoring and B-ultrasound monitoring of ovulation. Although basal body temperature is a biphasic body temperature, its high phase maintenance time is shorter than 11 days. B-ultrasound monitors that ovulation occurs when the follicles are not large enough (only about 15 mm). The quality of such eggs is not good. Generally, the follicles are required to grow to 18 mm to ovulate.

　　Atrophy of the corpus luteum. The patient's body temperature cannot rise quickly, but rises slowly like climbing a hill. It will rise by 0.2 degrees today and 0.2 degrees tomorrow. It will not last long when it reaches the peak, and then slowly goes downhill again. The main manifestation of menstruation is prolonged menstruation.
