What is the typical duration of the menstrual cycle?

The typical duration of the menstrual cycle is around 28 days. This cycle is counted from the first day of menstruation to the first day of the next period. While individual cycles can vary, with normal ranges extending from about 21 to 35 days, the 28-day cycle is often used as a standard reference point in both medical literature and educational contexts. This average duration is commonly associated with ovulation occurring around day 14, which is a key point in understanding fertility, hormonal changes, and the overall reproductive cycle. Awareness of this standard helps in recognizing any irregularities or variations that may occur in an individual's menstrual cycle.
