Which hormone is responsible for the development of the male reproductive system?

Correct Answer: B

Rationale: Testosterone is the correct answer because it is the primary male sex hormone responsible for the development and maintenance of the male reproductive system, including the development of male sex organs like the testes and penis. Estrogen (A) is the primary female sex hormone, not responsible for male reproductive system development. Progesterone (C) is involved in the female reproductive system and pregnancy, not in male development. FSH (D) is a follicle-stimulating hormone that plays a role in both male and female reproductive systems but is not responsible for the development of the male reproductive system specifically.

Correct Answer: C

Rationale: The correct answer is C because the main function of the female reproductive system is to provide a site for fertilization and support embryo development. This includes the production of eggs, the site for fertilization in the fallopian tubes, and the nurturing of the embryo in the uterus. Choices A and D are partially correct as the female reproductive system also produces hormones and regulates the menstrual cycle, but these are not the main functions. Choice B is incorrect as supporting fetal development occurs after fertilization and embryo development, which are the primary functions of the female reproductive system.

Correct Answer: B

Rationale: The correct answer is B: Secretes fluids that make up semen. The prostate gland secretes a milky fluid that makes up a significant portion of semen, aiding in sperm mobility and viability. This fluid also helps neutralize the acidic environment of the vagina, enhancing sperm survival. Option A is incorrect as the testes store sperm, not the prostate gland. Option C is incorrect as testosterone is primarily produced in the testes. Option D is incorrect as sperm production is regulated by the hypothalamus and pituitary gland, not the prostate gland.

Correct Answer: C

Rationale: The myometrium is the muscular layer of the uterus responsible for contracting during labor to facilitate childbirth. It helps push the baby out. Choice A is incorrect as the myometrium does not support the endometrial lining. Choice B is incorrect as the myometrium does not facilitate implantation. Choice D is incorrect as the myometrium does not secrete estrogen.

Correct Answer: A

Rationale: The correct answer is A: Ovary. Estrogen is primarily produced by the ovaries, specifically by the ovarian follicles. The ovaries contain specialized cells that produce estrogen in response to hormonal signals. Estrogen plays a crucial role in regulating the menstrual cycle, promoting the development of secondary sexual characteristics, and maintaining reproductive health. The other choices (B: Uterus, C: Fallopian tubes, D: Cervix) are incorrect because they do not play a direct role in the production of estrogen. The uterus is the organ where a fertilized egg implants and develops during pregnancy. The fallopian tubes are responsible for transporting eggs from the ovaries to the uterus. The cervix is the lower part of the uterus that connects to the vagina. While these structures are important for reproduction, they do not produce estrogen.
