Antral follicle count

An ultrasound count of small follicles visible at the start of a cycle.

Tests & investigations

The antral follicle count is used alongside AMH to estimate ovarian reserve and plan stimulation doses. Like AMH, it describes quantity rather than quality and cannot on its own predict whether pregnancy will occur.

Also known as: AFC, follicle count scan
