Question

Which hormone is primarily responsible for sexual and physical changes in girls during puberty?

पर्याय

• Testosterone

• Oestrogen

• Cortisol

• Insulin

Answer 1

Oestrogen is the primary hormone responsible for sexual and physical changes in girls during puberty. This hormone stimulates the development of female secondary sexual characteristics, including breast development, widening of the hips, menstruation, and changes in body fat distribution. Oestrogen is produced in the ovaries and increases significantly during adolescence, initiating the physiological transformations characteristic of female puberty.
