The antral follicle count: practical recommendations for better standardization.

Area of Science:

• Reproductive Endocrinology
• Medical Ultrasound
• Gynecology

Background:

• Antral Follicle Count (AFC) is crucial for predicting ovarian response in assisted reproductive technology (ART).
• Current methods for AFC assessment lack standardization, leading to variability in clinical practice and research.
• The precise nature of visualized follicles and oocyte competence remains unclear.

Purpose of the Study:

• To establish standardized recommendations for Antral Follicle Count (AFC) assessment.
• To address the variability in AFC measurement definitions and techniques.
• To improve the prediction of ovarian response in ART treatments.

Main Methods:

• A workshop convened specialists in reproductive medicine and scientists in December 2007.
• Literature review on ovarian antral follicle physiology and measurement.
• Discussion of clinical and technical considerations for AFC measurement, leading to an operational definition.

Main Results:

• Developed simple recommendations for standardizing AFC assessment in clinical practice.
• Agreed upon basic clinical and technical requirements for AFC evaluation.
• Proposed a systematic method for measuring and counting antral follicles.

Conclusions:

• Encourages the adoption of standardized AFC counting methods in clinical trials and practice.
• Advocates for systematic evaluation of these recommendations as standardized data emerge.
• Aims to enhance the reliability of ovarian response prediction in ART.
