menstruation
Cyclical changes during a woman's normal ovulatory menstrual cycle.
Before menarcheāthe first menstrual periodāa girl typically experiences several physical changes associated with the onset of puberty. These developments are driven by the production of estrogen and other hormones.12
Common body changes preceding menarche include:
- Breast Development: The appearance of the "breast bud" is usually the first observable sign of puberty, characterized by the enlargement of the nipples followed by the growth of breast tissue.312
- Growth Spurt: Girls enter a period of relatively rapid physical growth in height. Menarche typically occurs only after the peak height velocity has been passed.14
- Pubic and Axillary Hair: The growth of pubic hair often begins around the same time as breast development, and underarm (axillary) hair typically appears later.312
- Reproductive Organ Development: The uterus, vagina, labia, and clitoris enlarge and develop.32
- Body Composition: Fat deposits begin to develop on the hips and thighs, shifting the body toward a more rounded female contour.1
Menarche is a late event in this sequence, usually occurring about two or more years after the puberty process has begun.14
