What is Antral Follicle Count (AFC)?
AFC is a scan that counts the number of follicles in your ovaries - it helps estimate your egg reserve.
Antral Follicle Count (AFC) is a type of ultrasound scan that looks at your ovaries and counts the number of small follicles visible at the start of your menstrual cycle. These follicles contain immature eggs, so your AFC gives us a good idea of your ovarian reserve - how many eggs you might be working with. It's one of the key tests we use to personalise your fertility treatment and assess how your body may respond to stimulation.
