How long does the follicular phase typically last?

The follicular phase of the menstrual cycle typically lasts around 14 days. 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 under the influence of the follicle-stimulating hormone (FSH). The growth of these follicles is critical as it leads to the eventual release of an egg during ovulation.

It is important to recognize that while the average duration of the follicular phase can be about 14 days, there can be individual variations. Factors such as hormonal balance, health, and age can influence this duration, but 14 days is widely accepted as the standard length for a typical cycle in many women. Therefore, this answer aligns with established reproductive physiology.

Other options presented do not accurately reflect the typical duration of the follicular phase, as they either underestimate or overestimate the average length based on the majority of menstrual cycle data.
