The process of ovulation is the increase in the amount of estradiol secreted by the mature follicle before ovulation, which will play a positive feedback regulation on the hypothalamus, prompting the discharge of a large amount of gonadotropin-releasing hormone from the pituitary gland and the peak of luteinizing hormone secretion, thus causing the eggs to be excreted from the follicle for the purpose of ovulation. When a woman’s body hormone levels are low, the follicles do not develop and mature, which can lead to ovarian failure to ovulate in a timely manner. When ovulation does not occur, the ovaries are unable to combine with sperm to form a fertilized egg and the woman is unable to become pregnant. If a woman wants to become pregnant, her ovaries must have normal reproductive and endocrine functions and be able to discharge high quality eggs during ovulation, which will wait in the fallopian tubes to unite with sperm to develop into a fertilized egg.
