Question

Which hormone is primarily responsible for the development of secondary sexual characteristics in females?

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

Hint:

Estrogen is essential for the development of female secondary sexual characteristics. It is also crucial for regulating the menstrual cycle and supporting pregnancy.

Answer 1

The Correct Option is A

The development of secondary sexual characteristics in females, such as breast development, widening of hips, and the growth of body hair, is primarily controlled by the hormone estrogen. Estrogen is produced by the ovaries and plays a crucial role in the regulation of the menstrual cycle as well. 

Let's look at the other options: 

Option 1: Estrogen Estrogen is indeed the hormone responsible for the development of secondary sexual characteristics in females. It is involved in the growth and maturation of the reproductive organs and the development of secondary sexual traits during puberty. 

Option 2: Testosterone Testosterone is the primary male sex hormone and is responsible for the development of male secondary sexual characteristics such as facial hair, deep voice, and increased muscle mass. While it is present in females in smaller quantities, it is not responsible for female secondary sexual characteristics. 

Option 3: Progesterone Progesterone is another hormone produced by the ovaries that is primarily involved in regulating the menstrual cycle and preparing the body for pregnancy. It does not play a significant role in the development of secondary sexual characteristics. 

Option 4: Oxytocin Oxytocin is involved in childbirth and lactation but does not regulate secondary sexual characteristics. It is sometimes called the "love hormone" for its role in social bonding. Thus, the correct answer is Option 1: Estrogen.
