What secondary sex characteristic developments are common to boys and girls, and which characteristics are unique to each gender?
On Jun 13, 2024
Secondary sex characteristics are physical changes that occur during puberty as a result of hormonal changes. Both boys and girls experience some common secondary sex characteristic developments, such as the growth of pubic and underarm hair, increased body odor, and changes in skin texture. However, there are also unique developments for each gender.
Common developments for both boys and girls include the growth of facial and body hair, changes in voice pitch, and an increase in sweat gland activity. These changes are all a result of increased levels of testosterone in boys and estrogen in girls.
Unique developments for boys include the growth of the Adam's apple, increased muscle mass, and the deepening of the voice. These changes are all a result of the increased levels of testosterone during puberty.
Unique developments for girls include the growth of breasts, widening of the hips, and the onset of menstruation. These changes are all a result of the increased levels of estrogen during puberty.
Overall, while there are some common secondary sex characteristic developments for both boys and girls, there are also unique changes that occur as a result of the specific hormones present in each gender.
