Question

Which hormone is responsible for secondary sexual character in females?

• A. Testosterone
• B. Estrogen
• C. Thyroxine
• D. Vasopressin

Answer 1

The correct option is B Estrogen

• Secondary sexual characteristics develop during puberty which includes, enlargement of breasts and erection of nipples, growth of body hair, most prominently underarm and pubic hair, greater development of thigh muscles behind the femur rather than in front of it, widening of hips, lower waist to hip ratio than adult males, smaller hands and feet than men, rounder face, development of sexual organs.
• A steroid hormone responsible for the development of female characteristics in mammals is estrogen. The proper name for it is 'estradiol'.
• Whereas the thyroid gland secretes thyroxine, which controls the basic metabolic rate and the testes secrete testosterone, which is the male sex hormone.
• Vasopressin is a pituitary hormone that causes the kidney to reabsorb more water from urine.

So, the correct answer is 'Estrogen'.
