A dominant follicle grows at what rate per day?

• A. 1-2 mm
• B. 2-3 mm
• C. 3-4 mm
• D. 4-5 mm

Answer: (B)

Follicle growth during the follicular phase follows a fairly steady pace, and knowing this helps you time ovulation with ultrasound. The dominant follicle typically increases in diameter by about 2 millimeters per day. This rate is what clinicians use when they track follicular development on serial scans to estimate when ovulation may occur. If you see slower growth, around 1-2 mm per day, it would take longer to reach ovulatory size; faster growth, around 3-4 mm per day or more, is less common and can occur in atypical situations. The 2-3 mm per day range is the typical, expected rate that aligns with standard monitoring practice.
