Know your tests - Antral Follicle Count
Antral Follicle count is the total number of follicles in both ovaries, between 2-10mm, seen on a transvaginal ultrasound during the early follicular phase, between day2-4 of your menstrual cycle. It is a very important marker for ovarian reserve. If AFC is less than 5 then it is labeled as a poor ovarian reserve. Between 5-15 is considered normal. 15-25 is high AFC and >25 is seen in PCO patients. In recent studies, AMH ( antimullerian hormone) is said to have clinical significance only if AFC is poor (<5). If so then AMH and AFC both are considered to make a diagnosis of the poor ovarian reserve. AMH does not have much role when AFC is normal or high. A baseline scan on Day 2/3 of your menses is an important scan in your initial evaluation for subfertility
