Menstrual cycle

« Back to Glossary Index

The menstrual cycle, often summarized as menstruation, is a physiological and natural phenomenon, starting at the beginning of adolescence and ending at the menopause. This menstrual cycle requires perfect coordination between your various organs (brain, ovaries, [uterus]) and the means of communication your body has (neurons and vessels). Each woman will therefore have her own menstrual cycle according to her own age and contraceptive characteristics.

The purpose of the menstrual cycle is to allow the ovulation of an oocyte in order to achieve a pregnancy that will develop in a uterine lining (endometrium) that is regenerated every month. In the absence of pregnancy, this endometrium will be evacuated by the phenomenon of menstruation. Menstruation occurs every 28 days (length of the menstrual cycle). A variation between 21 and 35 days is considered normal.

The menstrual cycle is divided into three stages: the follicular phase (growth of the follicles containing the oocytes), the ovulation, the luteal phase (maintenance of the uterine lining endometrium).
