1. Which hormone is released from the testes?

• A. Progesterone
• B. Vasopressin
• C. Testosterone
• D. None of the above

Correct answer: C

Rationale: The correct answer is testosterone. Testosterone is the primary male sex hormone produced in the testes. Progesterone is a female sex hormone primarily produced in the ovaries, not in the testes. Vasopressin is a hormone released by the pituitary gland to regulate water balance in the body, not produced by the testes. Therefore, choices A, B, and D are incorrect.

2. When does missed abortion occur?

• A. The fetus dies and is retained in utero with the placenta and membranes.
• B. All products of conception are expelled with minimal bleeding.
• C. The cervix remains closed, and the products of conception remain in the uterus.
• D. The cervix remains closed, but there is heavy bleeding.

Correct answer: C

Rationale: Missed abortion occurs when the cervix is closed, and the products of conception remain in the uterus. Choice A describes a missed abortion, not choice C. Choice B describes a complete abortion. Choice D describes a threatened abortion, where the cervix remains closed but there is heavy bleeding.

3. Which of the following is the most effective method of contraception?

• A. Barrier methods
• B. Hormonal pills
• C. Intrauterine devices (IUDs)
• D. Sterilization

Correct answer: D

Rationale: Sterilization is considered the most effective method of contraception because it permanently prevents pregnancy. Barrier methods, hormonal pills, and IUDs are highly effective as well, but they are reversible methods and may have a higher failure rate compared to sterilization.

4. 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.

5. Inevitable abortion occurs when:

• A. The ovum dies in utero and the decidua capsularis remains intact.
• B. The cervix is open, and the products of conception are about to be expelled.
• C. The products of conception are expelled before the 20th week of gestation.
• D. The fetus dies and is expelled in the first trimester.

Correct answer: B

Rationale: Inevitable abortion occurs when the cervix is open, and the products of conception are about to be expelled. This is a critical point in the process of spontaneous abortion, indicating that expulsion of the products of conception is imminent. Choice A is incorrect as it describes a missed abortion where the ovum dies but the decidua capsularis remains intact. Choice C is incorrect as it describes an incomplete abortion where the products of conception are expelled before the completion of 20 weeks of gestation. Choice D is incorrect as it describes a missed abortion where the fetus dies and is expelled in the first trimester.
