The onset of puberty is primarily determined by genetics, specifically the activation of genes that control the timing of pubertal development. Puberty begins when the hypothalamus begins secreting gonadotropin-releasing hormone (GnRH), which then triggers the release of luteinizing hormone (LH) and follicle-stimulating hormone (FSH) from the pituitary gland, ultimately leading to the physical changes associated with puberty. While factors such as nutrition and environmental cues can affect the timing of puberty, they are secondary to genetic factors.
