Quizplus · Accepted Answer

The onset of puberty is initiated by the release of hormones, specifically gonadotropin-releasing hormone (GnRH) from the hypothalamus. This hormone stimulates the release of follicle-stimulating hormone (FSH) and luteinizing hormone (LH) from the pituitary gland, which then stimulate the production of sex hormones such as estrogen and testosterone. These hormones are responsible for the physical changes associated with puberty, such as growth of pubic and underarm hair, breast development, and changes in body shape. Sleep, weight, and nutrition can all impact the timing and progression of puberty, but the primary trigger is hormonal.
