Kuukautiskierrossa

Kuukautiskierrossa refers to the menstrual cycle, a natural and recurring monthly process in individuals with female reproductive organs. This cycle is primarily driven by hormonal fluctuations and prepares the body for a potential pregnancy. It typically begins with menstruation, commonly known as a period, which is the shedding of the uterine lining. This phase lasts for several days. Following menstruation, the follicular phase begins, during which an egg matures within an ovary. Ovulation then occurs, releasing the mature egg from the ovary. If fertilization does not happen, the luteal phase follows, where the uterine lining thickens in preparation for implantation. If pregnancy does not occur, the hormonal levels drop, triggering the start of menstruation again, thus completing the cycle. The average menstrual cycle is about 28 days long, but variations in length are common and considered normal. Factors like stress, diet, and certain medical conditions can influence the regularity and duration of the menstrual cycle. Understanding the menstrual cycle is important for reproductive health and family planning.
