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. Causes of metrorrhagia include:

• A. Cervical carcinoma
• B. Uterine polyp
• C. Cervical endometriosis
• D. Infections like Chlamydia

Correct answer: A

Rationale: Metrorrhagia refers to irregular menstrual bleeding that occurs between periods. Cervical carcinoma, a type of cancer that develops in the cervix, can lead to metrorrhagia. Uterine polyps, which are growths attached to the inner wall of the uterus, can also cause abnormal bleeding. While infections like Chlamydia can cause abnormal vaginal bleeding, they are not common causes of metrorrhagia. Cervical endometriosis, although a possible gynecological condition, is not a typical cause of metrorrhagia. Therefore, the correct answer is cervical carcinoma as it is a known cause of metrorrhagia, making the other options incorrect.

3. 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.

4. Expanded access to family planning through non-public delivery systems is facilitated by all of the following EXCEPT:

• A. By using the private sector and social marketing
• B. Community-based programs
• C. Information, Education, and Communication
• D. Key persons in the community

Correct answer: D

Rationale: Expanded access to family planning through non-public delivery systems involves utilizing various strategies to reach more people. Options A, B, and C are all effective methods for expanding access to family planning services. The involvement of key persons in the community is not a typical approach for non-public delivery systems. Key persons in the community may have influence but may not be directly involved in the delivery of family planning services, making option D the correct answer.

5. Which of the following are examples of external genitalia?

• A. Mons veneris
• B. Labia majora
• C. Vagina
• D. Cervix

Correct answer: A

Rationale: The correct answer is A: Mons veneris. The mons veneris and labia majora are considered external genitalia as they are visible externally. The vagina and cervix, on the other hand, are internal structures. The vagina is the canal leading from the external genitals to the cervix, which is the lower, narrow portion of the uterus.
