All women are born with a certain number of eggs. No more eggs are created or made after birth. When a menstrual cycle starts each month, a group of eggs begins to grow. One egg, called the dominant follicle, develops ahead of the rest, which will shut off the other eggs that are growing. This dominant follicle will then ovulate. (http://www.fertilitylifelines.com/aboutyourfertility/femalebiology.jsp) Even though only one egg releases, this process causes many eggs to be used up every month. By the time a woman reaches menopause, around age 52, no more eggs are left. In some women, menopause occurs at a very early age, before the age of 40. When menopause happens this early, it is termed premature ovarian failure and signifies that this woman’s eggs have been depleted earlier than expected. A milder version of this condition, called diminished ovarian reserve, suggests that a younger woman, say age 35, has fewer eggs left than she should for her age. With diminished ovarian reserve, a patient will ovulate like a 40-year-old and will become pregnant at the same rate as a 40-year-old, not a 35-year-old. Dr. Douglas can administer tests to check for ovarian reserve. The most popular are the day 3 FSH and estrogen. However, we may utilize other tests such as a sonogram for a basal follicle count, or a test called anti-Mullerian hormone, or AMH. With these screening tests, we can determine the status of the woman’s ovarian reserve. This information helps Dr. Douglas know what the chances of success are, and what doses of ovulation induction medication to use. |
