This signals the pituitary gland to release luteinizing hormone (LH) and follicle-stimulating hormone (FSH). These hormones stimulate the testes to produce testosterone. While testosterone is the primary male hormone responsible for muscle growth and voice changes, the development of pubic hair is specifically triggered by androgens, particularly a hormone called dihydrotestosterone (DHT), which is derived from testosterone. Additionally, the adrenal glands produce weak androgens that contribute to the early stages of pubic hair growth. : He may be a slow maturer
