Secondary sexual characteristics are the physical changes that emerge during puberty, distinguishing male and female bodies.
These changes occur under the influence of sex hormones (testosterone and estrogen) and are not directly involved in reproduction but indicate sexual maturity.
Breast development: Growth of breast tissue, starting with breast buds.
Widening of hips: Hips widen as the pelvis prepares for potential childbirth.
Body fat distribution: Increased fat deposition in hips, thighs, and buttocks.
Menstruation: Onset of menarche (first menstrual period), signaling reproductive maturity.
Growth of body hair: Appearance of hair in the underarms and pubic area.
Oilier skin and acne:Increased sebaceous gland activity
Development of sweat glands: Increase in perspiration and body odor due to active apocrine glands.
Growth spurt: Significant increase in height and changes in overall body shape.
Changes in skin texture: Skin may become thicker and oilier.
These changes typically occur during puberty, starting around ages 8–13 in females.
