Reproductive System Exam Questions

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

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. What is one goal of family planning?

Correct answer: A

Rationale: The correct answer is A. Family planning aims to ensure that all couples and individuals have the basic right to decide freely and responsibly the number and spacing of their children. This promotes reproductive autonomy and allows individuals to make informed choices about their family size. Choices B, C, and D are incorrect because they involve imposing restrictions or decisions on family size rather than empowering individuals to make their own choices.

3. What is the primary use of Bromocriptine?

Correct answer: C

Rationale: Bromocriptine is primarily used to affect milk production. It is a medication commonly prescribed to help suppress lactation, particularly in cases of postpartum breast engorgement or when stopping breastfeeding. Choices A, B, and D are incorrect as Bromocriptine is not indicated for relieving constriction ring, managing post-partum hemorrhage, or treating pre-eclampsia.

4. Which of the following is not a characteristic of an ideal contraceptive?

Correct answer: A

Rationale: The correct answer is A: 'Irreversible.' An ideal contraceptive should not be irreversible because it should allow individuals to have the option to discontinue its use if desired. Choices B, C, and D are characteristics of an ideal contraceptive. Contraceptives should be easily available to ensure widespread accessibility, user-friendly to promote proper and consistent use, and effective with minimal side effects to maximize safety and tolerability.

5. What is the function of luteinizing hormone?

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.
