Antral follicle count

窦卵泡计数

Common aliases: 基础卵泡数, 窦卵泡数量, AFC 检查
Use in consultation: Information organization and clinic communication

Overview

Antral follicle count is assessed by ultrasound and reflects the visible pool of small follicles at that time. It can vary by cycle, operator and equipment, so it is reviewed as part of a complete clinical picture.

AFC is the number of small antral follicles seen on ultrasound, usually near the beginning of a cycle. It is often used with AMH to discuss ovarian response.

Category: Tests & indicators
Chinese term: 窦卵泡计数
Boundary: Not medical diagnosis

KEY POINTS

What to clarify

01Helps estimate response to ovarian stimulation
02Depends on scan timing and ultrasound quality
03Should be interpreted together with AMH and age
04Not the same as final egg retrieval count

Clinical use

AFC helps turn ultrasound information into clinic questions about stimulation, monitoring frequency and expected response.

Medical interpretation, medication choices and treatment decisions should be confirmed by licensed clinicians and the selected hospital.

01Which cycle day was the scan performed?
02Were both ovaries clearly visible?
03Does the clinic need a repeat ultrasound before planning treatment?
