The possible causes of rapid decline in ovarian function in women include: internal diseases, ovarian surgery, chemoradiotherapy, etc. However, there are still some women with unexplained premature ovarian failure, and it is difficult to know if you are one of the “unexplained premature ovarian failure group” except by referring to the age of menopause of your blood relatives (such as your mother, aunts or uncles), so it is important to check your ovarian function proactively. How do I get an ovarian function test? Ovarian function tests are also known as sex six ovarian function tests, or sex hormone six ovarian function tests. In medical theory, the so-called “sex hormone test” is a routine basic examination in reproductive medicine, through the measurement of sex hormone levels to understand female endocrine function and diagnose diseases related to endocrine disorders. P), testosterone (T), and prolactin (PRL), which are basically sufficient for clinicians to screen for endocrine disorders and gain a general understanding of physiological functions. Generally speaking, the best time to check endocrine secretion is on the 3rd-5th day after menstruation, which is the early follicular period and can reflect the functional status of the ovaries. However, for those who do not have menstruation for a long time and are eager to know the results of the examination, the examination can be done at any time, and this time is by default the time before menstruation, and the results will refer to the results of the luteal phase examination; for those who are infertile or amenorrheic and do not have menstruation for a long time, the examination can be done at any time, and fasting is best. Ovarian function examination methods include the following four points: 1. Basal body temperature. Measure the body temperature with a meter in the morning, record the basal body temperature and draw a graph to check whether there is ovulation, the date of ovulation and the function of ovarian corpus luteum for more than 3 months. 2. Cervical mucus examination. Cervical mucus is secreted by the endocervical lining secretory cells and is affected by estrogen and progesterone. The amount, transparency, viscosity, crystallization and epithelial cell changes of cervical mucus can be used to determine ovarian function. 3. Endometrial examination. Endometrium is taken 1-3 days before menstruation or within 12 hours at the beginning of menstruation and sent to the laboratory for pathological examination. If the result of pathological examination is secretory endometrium, it indicates ovulation, while proliferative endometrium is not ovulated. 4. Vaginal exfoliative cell examination. The vaginal epithelium is directly affected by ovarian endocrine secretion and behaves differently with changes in the amount of estrogen and progesterone, and the ovarian function can be grasped by vaginal smear.
