पर्याय

• Testes in males producing sperm

• Ovaries in females producing eggs

• The hypothalamus regulating reproductive hormones

Secondary sexual characteristics are physical features that develop during puberty but do not directly participate in reproduction. Examples include beards and facial hair in males and breast development in females. These features are controlled by sex hormones but are distinct from the primary reproductive organs and gamete production.
