Which sex hormone is responsible for the development and regulation of the female reproductive system and secondary sex characteristics?

• A. Estrogen
• B. Progesterone
• C. Testosterone
• D. Androgen

Answer: (A)

Estrogen is the key hormone that drives the development of female reproductive organs and the secondary sex characteristics, such as breast development, body fat distribution, and the regulation of the menstrual cycle. It works with other hormones to coordinate the growth and shedding of the uterine lining and overall female reproductive function. Progesterone mainly prepares the uterus for pregnancy and modulates the cycle after ovulation. Testosterone is the primary male hormone (present in smaller amounts in females), and androgens are a broader class that includes testosterone but are not specifically responsible for female development.
