The menstrual cycle repeats from puberty (starting anywhere from the age of nine to 16) to menopause (which is when periods naturally stop – usually somewhere around the age of 50). When there’s no pregnancy (which is most of the time), the menstrual cycle repeats itself over and over again. If a pregnancy occurs, the menstrual cycle stops cycling. Under the influence of hormones, mostly oestrogen and progesterone, the menstrual cycle is a series of changes that the uterus and other female reproductive organs go through about once a month. The purpose of the menstrual cycle is to prepare the uterus for pregnancy. The menstrual cycle is a mystery to a lot of people, but it needn’t be! Half of the earth’s population has a menstrual cycle and without it, the human species wouldn’t even exist! Obviously, it’s a common, normal, and important part of life, so shouldn’t we all understand it? We think so. By Dr Melisa Holmes, OB-GYN & Founder of Girlology
