1. What is the role of the corpus luteum during the menstrual cycle?

• A. The corpus luteum produces estrogen to maintain the endometrium.
• B. The corpus luteum produces progesterone to maintain the endometrium.
• C. The corpus luteum produces testosterone to inhibit ovulation.
• D. The corpus luteum has no significant role during the menstrual cycle.

Correct answer: B

Rationale: The correct answer is B: The corpus luteum produces progesterone to maintain the endometrium during the menstrual cycle. This hormone helps prepare the uterine lining for implantation in case fertilization occurs. Choice A is incorrect because estrogen is mainly produced by the developing follicles in the ovaries. Choice C is incorrect as testosterone is produced in smaller amounts by the ovaries and adrenal glands but does not play a significant role in maintaining the endometrium. Choice D is incorrect as the corpus luteum plays a crucial role in producing progesterone to support the endometrium.

2. What does Bidder's canal receive?

• A. Eggs
• B. Sperms
• C. Ammonia
• D. Oxygenated blood

Correct answer: B

Rationale: Bidder's canal is a part of the male reproductive system and receives sperm from the testes. The other choices are incorrect because Bidder's canal is not associated with receiving eggs, ammonia, or oxygenated blood.

3. Which of the following tests is positive in pelvic inflammatory disease?

• A. Cervical excitation test
• B. Chadwick sign
• C. Jacquiners sign
• D. Palmers sign

Correct answer: A

Rationale: The correct answer is A: Cervical excitation test. The cervical excitation test is positive in pelvic inflammatory disease. This test involves pain or tenderness upon movement of the cervix, indicating inflammation of the pelvic organs. Chadwick sign (choice B) refers to a bluish discoloration of the cervix, vagina, and labia due to increased vascularity and is not a test for PID. Jacquiners sign (choice C) and Palmers sign (choice D) are not recognized clinical signs or tests for PID, making them incorrect choices.

4. What is the content of the acrosome?

• A. Lipids
• B. Hormones
• C. Digestive enzymes
• D. None of the above

Correct answer: C

Rationale: The correct answer is C: Digestive enzymes. The acrosome is a structure found in sperm cells that contains enzymes used to penetrate the egg during fertilization. Choice A (Lipids) and Choice B (Hormones) are incorrect as the primary content of the acrosome is digestive enzymes, not lipids or hormones. Choice D (None of the above) is incorrect as the acrosome does contain a specific substance, which are digestive enzymes.

5. _______ 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.
