Which part of the male reproductive system is responsible for the production of seminal fluid?

Correct Answer: C

Rationale: The correct answer is C: Seminal vesicles. Seminal vesicles produce seminal fluid, which is a major component of semen. This fluid provides nutrients and protection for sperm, aiding in their motility and survival. The other choices are incorrect because: A: Epididymis - Stores and transports sperm, but does not produce seminal fluid. B: Prostate gland - Produces a milky fluid that helps nourish and protect sperm, but it is not the primary site for seminal fluid production. D: Testes - Produce sperm through spermatogenesis, but do not directly produce seminal fluid.

Correct Answer: A

Rationale: The correct answer is A: LH (Luteinizing Hormone). LH surge triggers ovulation by stimulating the release of eggs from the ovary. It works in conjunction with FSH to facilitate follicle development. Estrogen supports the growth of the uterine lining, while progesterone maintains it post-ovulation. FSH is responsible for follicle development but isn't the primary hormone for egg release.

Correct Answer: B

Rationale: The correct answer is B: Progesterone. Progesterone is responsible for thickening the endometrial lining in preparation for pregnancy by promoting the growth of blood vessels and glands. It also helps maintain the uterine lining to support a fertilized egg. Estrogen (choice A) stimulates the growth of the endometrium but progesterone is crucial for thickening. FSH (choice C) and LH (choice D) are involved in the regulation of the menstrual cycle and ovulation, not specifically in thickening the endometrial lining.

Correct Answer: A

Rationale: Estrogen is the correct answer as it is the primary hormone responsible for the development of the female reproductive system during puberty. It stimulates the growth of the ovaries, regulates the menstrual cycle, and promotes the development of secondary sexual characteristics. Progesterone is involved in maintaining pregnancy, not puberty. FSH (Follicle Stimulating Hormone) is involved in the maturation of ovarian follicles, not overall reproductive system development. Testosterone is a male sex hormone and is not primarily responsible for the development of the female reproductive system.

Correct Answer: D

Rationale: The correct answer is D (All of the above) because all three hormones (FSH, LH, and Estrogen) play crucial roles in regulating the menstrual cycle. FSH stimulates the growth of ovarian follicles, LH triggers ovulation and promotes the formation of the corpus luteum, and Estrogen helps in the development and maintenance of the uterine lining. Together, these hormones work in a coordinated manner to ensure the proper functioning of the menstrual cycle. Therefore, selecting all of the above is the correct choice as each hormone is indispensable in the regulation of the menstrual cycle.
