1. What is the function of luteinizing hormone?

• A. Maintains the corpus luteum
• B. Ripens the Graafian follicle
• C. Prepares the breasts for lactation
• D. Produces regrowth of the endometrium

Correct answer: A

Rationale: Luteinizing hormone is responsible for maintaining the corpus luteum after ovulation. This is crucial for the production of progesterone, which helps prepare the endometrium for implantation and supports early pregnancy. Choices B, C, and D are incorrect: B is the function of follicle-stimulating hormone (FSH) which stimulates the growth of ovarian follicles, C is mainly regulated by prolactin, and D is primarily associated with estrogen and progesterone.

2. Which of the following structures is responsible for the production of sperm?

• A. Epididymis
• B. Seminal vesicles
• C. Testes
• D. Prostate gland

Correct answer: C

Rationale: The testes are the male reproductive organs responsible for the production of sperm through a process called spermatogenesis. The epididymis is a structure where sperm mature and are stored temporarily. Seminal vesicles produce a significant portion of the fluid that ultimately becomes semen, but they do not produce sperm. The prostate gland contributes additional fluid to semen but does not produce sperm. Therefore, the correct answer is the testes.

3. What is an organelle that helps the sperm to penetrate the ovum?

• A. Acrosome
• B. Zona pellucida
• C. Megalis
• D. None of the above

Correct answer: A

Rationale: The correct answer is Acrosome. The acrosome is an organelle located at the head of a sperm cell and contains enzymes that aid in the penetration of the ovum during fertilization. The Zona pellucida is a glycoprotein membrane surrounding the ovum, not an organelle. Megalis is not a relevant organelle in this context. Therefore, the correct choice is A, Acrosome.

4. A diet rich in _______ controls menopause symptoms:

• A. Carbohydrates
• B. Soya items
• C. Fruits and veggies
• D. Eggs and meat

Correct answer: B

Rationale: A diet rich in soya items can help control menopause symptoms. Soya contains phytoestrogens, which are plant-based compounds that mimic the hormone estrogen in the body. These compounds may help alleviate menopause symptoms such as hot flashes and night sweats. Choice A, Carbohydrates, do not specifically target menopause symptoms. Choice C, Fruits and veggies, while generally healthy, do not have the same impact on menopause symptoms as soya. Choice D, Eggs and meat, do not contain phytoestrogens like soya, making them less effective in managing menopause symptoms.

5. What is one role of the hormone estrogen?

• A. Stimulates the development of the milk-producing tissue.
• B. Stimulates the production of lactoferrin.
• C. Stimulates the development of the nipple and duct system in the breast.
• D. Stimulates the secretion of relaxin.

Correct answer: A

Rationale: The correct answer is A: Estrogen stimulates the development of the milk-producing tissue in the breast. This hormone is essential in preparing the breast for milk production. Choice B is incorrect because lactoferrin production is not a primary role of estrogen. Choice C is incorrect as estrogen primarily influences the development of the breast tissue rather than specifically the nipple and duct system. Choice D is incorrect because relaxin secretion is not a function typically associated with estrogen.
