What is menses?

Menses refers specifically to the shedding of the endometrial lining from the uterus during a woman's menstrual cycle. This process occurs when fertilization does not take place, leading to a decrease in hormone levels, which subsequently triggers the breakdown and expulsion of the lining through the vagina. This cycle typically lasts about 28 days, although variations in length are normal.

While menses is closely related to other phases of the menstrual cycle, such as ovulation and preparation of the uterus for potential pregnancy, it distinctly represents the actual event of menstruation itself. Overall hormonal fluctuations throughout the cycle govern when menses occurs, encapsulating its specific definition and relevance within female reproductive health.
