1. _______ is a lytic enzyme released by the sperm.

• A. Hyaluronidase
• B. Trypsin
• C. Helicase
• D. None of the above

Correct answer: A

Rationale: Hyaluronidase is the correct answer. It is a lytic enzyme released by the sperm to help penetrate the egg's protective layer. Trypsin is a digestive enzyme produced in the pancreas, not released by sperm. Helicase is an enzyme involved in DNA replication, not released by sperm. 'None of the above' is incorrect as hyaluronidase fits the description provided in the question.

2. The structures of the vulva lie ____________ to the vagina.

• A. Posterior
• B. Inferior
• C. Lateral
• D. Superior

Correct answer: B

Rationale: The correct answer is 'Inferior.' The structures of the vulva are positioned below the vagina, making them inferior. Choice A, 'Posterior,' refers to structures located at the back, not below the vagina. Choice C, 'Lateral,' means to the side, which is not the correct orientation in this context. Choice D, 'Superior,' indicates above, which is the opposite of the correct relationship described in the question.

3. What type of tissue lines the testes?

• A. Glandular tissue.
• B. Squamous epithelium.
• C. Transitional epithelium.
• D. Stratified epithelium.

Correct answer: A

Rationale: The correct answer is A: Glandular tissue. The testes are lined with seminiferous tubules, which contain germ cells and Sertoli cells that are involved in sperm production. These cells are part of the glandular tissue that makes up the testes. Choices B, C, and D are incorrect because squamous, transitional, and stratified epithelium are not typically found lining the testes. Squamous epithelium is a type of epithelial tissue found in areas like the skin, transitional epithelium lines organs like the bladder, and stratified epithelium is present in structures like the skin and esophagus.

4. Which of the following is a contraceptive?

• A. Copper T
• B. Condom
• C. Diaphragm
• D. All of these

Correct answer: D

Rationale: The correct answer is D, All of these. Copper T, Condom, and Diaphragm are all examples of contraceptives used to prevent pregnancy. Copper T is an intrauterine device (IUD) that is placed inside the uterus to prevent pregnancy. Condoms are barrier contraceptives worn over the penis or inserted into the vagina to prevent sperm from reaching the egg. Diaphragms are also barrier contraceptives that cover the cervix to prevent sperm from entering the uterus. Therefore, all options listed (Copper T, Condom, Diaphragm) are indeed contraceptives, making 'All of these' the correct choice.

5. The products of conception are retained in which of the following?

• A. Complete abortions
• B. Incomplete abortions
• C. Threatened abortion
• D. Mixed abortion

Correct answer: B

Rationale: In incomplete abortions, the products of conception are retained. In a complete abortion, all the products of conception are expelled from the uterus. Threatened abortion refers to a situation where there is vaginal bleeding but the cervix remains closed, and it does not necessarily involve retention of products of conception. Mixed abortion is not a recognized medical term related to retained products of conception.
