The ovaries are two important reproductive organs located in the female pelvis, 2 x 3 x 4 CM in size, which maintain normal menstruation; are the source of vital hormones in the female body; and produce eggs that are fertilized with sperm to form life. Young women have slender curves and delicate, smooth skin thanks to their ovaries, but as they age, their ovarian reserve gradually declines, women’s skin begins to sag, their libido begins to decline, abdominal fat begins to accumulate, and bone deposition is affected to form osteoporosis. We care about the ovaries not only because they maintain a high quality of life for healthy women, but also because they produce the eggs that allow human beings to reproduce life. Human life comes from the union of sperm and egg, which meet in the fallopian tube, unite and develop into a fertilized egg, which divides and is transported down the fallopian tube to the uterine cavity where it is planted and develops to form a living individual. The first requirement for a natural pregnancy is a female egg, functioning fallopian tubes and male sperm. Some patients with ovulation disorders, blocked fallopian tubes, and low or weak sperm in the male partner can achieve pregnancy through IVF. The age of the male has very little effect on the sperm, while the age of the female determines the number and quality of the eggs and the chance of pregnancy. In men, sperm are produced by spermatogenic cells in the spermatogenic tubules of the testes and can divide continuously. In contrast, the number of eggs in the female body is determined at birth, in a resting state, and most are atretic, or physiologically dead, before sexual maturity; the remaining eggs cycle continuously into a growth cycle, with each collection taking about 120 days of growth to form a large dominant follicle for ovulation, with about 1000 follicles entering at the beginning of each collection The number of eggs in a woman’s ovary decreases as she ages; the quality of the eggs in the ovary decreases over the decades due to the influence of the external environment and the local environment of the ovary, which is the main reason why older women are prone to having abnormal babies and the low pregnancy rate in IVF. This is the main reason for the low pregnancy rate in IVF. Ovarian function in women declines inexorably with age as a life course, especially after the age of 37, and is on a steep decline. Some women cannot understand why my ovarian function declines when my menstrual cycle is still accurate. We cannot judge ovarian function solely based on menstrual cycles. The onset of menstruation only indicates the development of follicles and ovulation, not the number and quality of fertile follicles in your ovaries. In patients who have had regular menstrual cycles in the past with a significant decline in ovarian function, the menstrual cycle may be shorter at first because your follicles are starting earlier than normal; the varying length of the menstrual cycle means a further decline in ovarian function because the follicles are not developing regularly. There are some patients with irregular menstrual cycles and a large proportion of them have polycystic ovaries. As long as the fallopian tubes are open, many of these patients can conceive naturally or through ovulation, and studies now show that at the same age, their ovarian reserve is higher than that of women with normal ovulation, and the tendency of ovarian function to decline is slower. For such women, progesterone is used periodically to maintain menstruation to protect the endometrium or other oral medications to prevent other endocrine complications. In some women, no menstruation occurs before the age of 40, which is called premature ovarian failure. The low estrogen status in the body can cause hot flashes, mood changes, vaginal dryness and decreased libido. These women should use exogenous estrogen and progesterone to maintain a normal physiological state and improve their quality of life. Nowadays, women should pay attention to their lifestyle and stress, not to consume foods containing too many food additives, to have harmonious interpersonal relationships and to maintain a balanced state of mind. For patients with premature ovarian failure, early hormone replacement should be used to maintain the quality of life.
