What is menarche?

What is menarche?

• A. The monthly shedding of the uterine lining.
• B. The first time occurrence of menstruation, marking the beginning of reproductive years.
• C. The release of a mature egg from an ovary.
• D. The natural cessation of menstrual cycles, marking the end of reproductive years.

Answer: (B)

Menarche is the first menstrual period, the moment when menstruation begins for the individual and the reproductive years start. It reflects the maturation of the hormonal system that governs menstrual cycles (the hypothalamic-pituitary-ovarian axis) and often comes with cycles that may be irregular at first. It’s not the monthly shedding itself (that’s menstruation happening in each cycle), not the release of an egg (ovulation), and not the end of cycles (menopause). Menarche signals the start of fertility potential, even though ovulation may not occur every cycle right away.
