Most women experience their final menstrual cycle around the age of 51. The ceasing of the menstrual cycle is called
menopause, and it signals the end of a woman's reproductive years. It's triggered by a change in hormone levels and
a decline in oocytes. Doctors can perform a test to check a woman's hormone levels to determine if menopause has
occurred. If the woman is in menopause, the test will reveal high FSH levels and low estrogen levels.
How could a decline in the number of oocytes contribute to this change in hormones?
