1. Which contraceptive option suppresses sperm motility and inhibits the implantation of the blastocyst?

• A. Copper-T
• B. Diaphragm
• C. Contraceptive pills
• D. Condom

Correct answer: A

Rationale: The correct answer is A, Copper-T. Copper-T is an intrauterine device that releases copper ions, which suppress sperm motility and inhibit the implantation of the blastocyst. This method mainly works by preventing fertilization and, if fertilization occurs, by making the endometrium less receptive to implantation. Choices B, C, and D are incorrect. The diaphragm is a barrier method that prevents sperm from reaching the cervix; contraceptive pills mainly work by suppressing ovulation and altering cervical mucus to prevent sperm from reaching the egg; condoms are barrier methods that prevent sperm from entering the vagina.

2. How does human sperm move?

• A. Flagella
• B. Cilia
• C. Neutrophils
• D. None of the above

Correct answer: A

Rationale: Human sperm moves using flagella, which are whip-like structures that aid in propulsion. Flagella are tail-like structures found in sperm cells and help them swim towards the egg for fertilization. Cilia are shorter, hair-like structures that are not involved in the movement of sperm. Neutrophils are a type of white blood cell involved in the immune response and are not related to sperm locomotion.

3. The _________ is a temporary organ that connects a mammalian mother to its foetus.

• A. Placenta
• B. Chorion
• C. Endometrium
• D. None of the above

Correct answer: A

Rationale: The correct answer is A: Placenta. The placenta is a temporary organ that connects a mammalian mother to its foetus. It plays a crucial role in facilitating the exchange of nutrients, oxygen, and waste between the mother and the developing baby. Choice B, Chorion, is incorrect as it is a part of the fetal membrane but not the organ that connects the mother to the fetus. Choice C, Endometrium, is incorrect as it is the lining of the uterus where implantation occurs but is not the organ responsible for connecting the mother to the fetus. Choice D, None of the above, is incorrect as the placenta specifically fits the description provided in the question.

4. 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.

5. Which of the following is used to differentiate abdominal mass from pelvic mass on clinical examination?

• A. Size
• B. Site
• C. Margins
• D. Lower border

Correct answer: D

Rationale: The lower border is used to differentiate between an abdominal mass and a pelvic mass during clinical examination. The lower border of the mass provides important information about its location and origin. The size (Choice A) alone may not always clearly distinguish between abdominal and pelvic masses. The site (Choice B) and margins (Choice C) are also important factors, but they are not as specific in differentiating between abdominal and pelvic masses as the lower border.
