Which is more important, FSH or AMH?
FSH and AMH are two indicators related to ovarian function, used to assess female reproductive health, and both are generally important. The specific analysis is as follows:
FSH is a hormone secreted by the anterior pituitary gland that promotes the growth and development of follicles within the ovary. A woman's ovaries produce varying levels of FSH at different stages of the menstrual cycle, so FSH levels can be used to evaluate ovarian function and reproductive health. Normally, FSH levels are lowest on the second or third day of the menstrual cycle and gradually rise as follicles grow and develop, reaching a peak just before ovulation. AMH is a hormone produced in the ovaries that promotes follicular development and maturation. AMH levels reflect the number and quality of follicles in a woman’s ovaries—namely, her ovarian reserve. Therefore, AMH is primarily used to assess ovarian reserve and reproductive health.
Although FSH and AMH can reflect a woman’s reproductive health, they also have certain limitations. For example, if a woman is taking oral contraceptives or other medications that affect ovarian function, these may influence FSH and AMH levels. Therefore, when using these markers for assessment, it is necessary to combine them with other clinical indicators and comprehensive evaluation by a physician.
