1. 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.

2. Which animal is an ovoviviparous animal?

• A. Basking shark
• B. Bonobo
• C. Blue shark
• D. None of the above

Correct answer: C

Rationale: The correct answer is the Blue shark. Ovoviviparous animals produce eggs that develop inside the body of the parent, and the offspring are born alive. The basking shark does not fall under this category as it is ovoviviparous, meaning it lays eggs that hatch inside the female's body. The bonobo is a separate species and not relevant to the question.

3. During menopause, what do ovaries stop producing?

• A. Progesterone and Estrogen
• B. Prolactin
• C. Human chorionic gonadotropin
• D. Oxytocin

Correct answer: A

Rationale: During menopause, the ovaries stop producing progesterone and estrogen. Progesterone and estrogen are hormones essential for the menstrual cycle and reproductive functions. Prolactin is a hormone responsible for milk production in the breasts and is not primarily produced by the ovaries. Human chorionic gonadotropin (hCG) is produced during pregnancy to support the production of progesterone and estrogen. Oxytocin is a hormone involved in labor and breastfeeding, not primarily produced by the ovaries.

4. The placenta is developed from which part of the trophoblast?

• A. Chorionic Frondosum
• B. Anchoring Villi
• C. Chorionic Laeve
• D. Body Stalk

Correct answer: A

Rationale: The correct answer is A: Chorionic Frondosum. The placenta is developed from the chorionic frondosum part of the trophoblast. This structure gives rise to the fetal part of the placenta. Choices B, C, and D are incorrect. Anchoring Villi are projections from the chorionic plate that attach the placenta to the uterine wall. Chorionic Laeve refers to the smooth chorion that covers the fetal surface of the placenta. The Body Stalk is a structure that connects the early embryo to the trophoblastic pole of the blastocyst.

5. Risk of endometrial hyperplasia is greatest in individuals who do not menstruate for at least _____ months and require immediate referral:

• A. 2 months
• B. 3 months
• C. 4 months
• D. 5 months

Correct answer: C

Rationale: The correct answer is C: '4 months.' The risk of endometrial hyperplasia is highest in individuals who do not menstruate for at least 4 months. This prolonged exposure to unopposed estrogen can lead to endometrial hyperplasia. Choices A, B, and D are incorrect because the risk is greatest after at least 4 months of not menstruating, not 2, 3, or 5 months.
