Final answer:
Estrogen controls breast development, the menstrual cycle, and female sex organ development but does not control the development of male sex organs. The correct answer to the question is option 3) male sex organs.
Step-by-step explanation:
All of the following are controlled by estrogen EXCEPT male sex organs. Estrogen is a sex hormone responsible for the development and regulation of the female reproductive system and secondary sexual characteristics. Here's a clarification of the roles of estrogen:
- Breast Development: Estrogen causes breast development during puberty and influences the deposition of fat in the breasts during adulthood.
- Menstrual Cycle: The hormone plays a critical role in regulating the menstrual cycle by promoting the growth of the uterine lining during the first half of the cycle and working together with progesterone to prepare the uterus for possible pregnancy.
- Female Sex Organs: Estrogen causes the growth of the uterus and the broadening of the hips. It is also essential for the growth and maintenance of the female reproductive tract.
- Male Sex Organs: Estrogen is not involved in the development of male sex organs. Instead, androgens such as testosterone and androsterone control the development of male secondary sex characteristics and reproductive functions.
Therefore, the correct answer to the student's question is option 3) male sex organs.
