Menstrual Cycle Phases
The menstrual cycle is a monthly process in the female reproductive system, typically lasting about 28 days. It consists of four main phases: the menstrual phase (shedding of the uterine lining), the follicular phase (egg development in the ovaries), ovulation (release of a mature egg), and the luteal phase (preparation of the uterus for possible pregnancy). Hormones like estrogen and progesterone regulate these phases, supporting fertility and reproductive health.
