The process is initiated by the hypothalamus, which releases Gonadotropin-Releasing Hormone (GnRH). This stimulates the anterior pituitary gland to secrete Follicle-Stimulating Hormone (FSH) and Luteinizing Hormone (LH). These hormones trigger the gonads (ovaries in females, testes in males) to produce sex steroidsтАФestrogen in females and testosterone in malesтАФwhich drive secondary sexual characteristics.
Puberty is marked by the onset of menarche in females and spermarche in males.
The process involves significant changes in the endocrine system and physical growth (growth spurt).
Genetic factors, nutrition, and environmental stress can influence the exact age of onset.
Attainment of reproductive capability
Development of secondary sexual characteristics
Potential for emotional instability due to hormonal fluctuations
Increased susceptibility to acne and physiological stress
Biological development of human species
Understanding pediatric endocrinology

A is correct тАФ The age range 10-14 years for females and 12-16 years for males represents the standard physiological window for the onset of puberty in humans.
