Question

The hormone responsible for changes in female at puberty is

• A. Estrogen and progesterone
• B. Progesterone
• C. Testosterone
• D. Oxytocin

Answer 1

The correct option is A Estrogen and progesterone

Estrogens are primary female sex hormones that serve in maturation and maintenance of sex organs, development of female secondary sexual characters and initiation of menstrual cycle. Likewise, progesterone prepares the body for pregnancy and maintain the uterus if pregnancy occurs. Along with estrogens, progesterone helps initiate menstrual cycle in girls entering the puberty. Both enzymes work synergistically.

Testosterone is male sex hormone which is responsible for development of male secondary sexual characters in males.

Oxytocin (OT) stimulates uterine muscle contraction during childbirth and initiates release of milk by mammary gland.

Therefore, the correct answer is option A.
