How long is the follicular phase of the ovarian cycle?

• A. 7 days
• B. 14 days
• C. 21 days
• D. 28 days

Answer: (B)

The follicular phase of the ovarian cycle typically lasts about 14 days, though it can vary somewhat from one individual to another. This phase begins on the first day of menstruation and continues until ovulation occurs. During this time, several follicles in the ovaries begin to mature, which is stimulated by the hormone follicle-stimulating hormone (FSH). The 14-day duration is a key aspect of the standard 28-day menstrual cycle, as it represents the first half of the cycle leading up to ovulation, which usually occurs around the midpoint. This phase is crucial for the development of the egg that will be released during ovulation, as well as for preparing the uterine lining for potential implantation. Understanding the duration and function of the follicular phase is essential for grasping the overall mechanics of the menstrual cycle and reproductive health.
