If a woman of childbearing age has good ovarian function, it will be reflected in her normal menstruation. For those who have normal menstruation, that is, her cycle and period are normal, it suggests that her ovarian function is still good. If there is irregular menstruation, decreased menstrual flow, or amenorrhea, or even infertility, it is possible that the ovaries are not functioning well. Possible causes of ovarian dysfunction include poor ovarian ovulation, ovarian hypoplasia, and possibly premature ovarian failure. How to determine this?
