1. Approximately how many primordial follicles are present in the cortex of the ovary at birth?

• A. 250,000
• B. 200,000
• C. 150,000
• D. 100,000

Correct answer: A

Rationale: The correct answer is A: 250,000. At birth, there are approximately 250,000 primordial follicles in the cortex of each ovary. These primordial follicles represent the reserve of oocytes that a female will have throughout her reproductive life. Choice B, 200,000, is incorrect as the number is higher. Choices C and D, 150,000 and 100,000 respectively, are also incorrect as they underestimate the actual number of primordial follicles present at birth.

2. The Wolffian duct is also known as ____________.

• A. Mesonephric duct
• B. Ejaculatory duct
• C. Major sublingual duct
• D. Cystic duct

Correct answer: A

Rationale: The correct answer is A: Mesonephric duct. The Wolffian duct is indeed also known as the mesonephric duct. This duct plays a vital role in the development of the male reproductive system by carrying sperm from the epididymis to the ejaculatory duct. Choice B, Ejaculatory duct, is incorrect as it refers to a different duct responsible for transporting semen from the vas deferens. Choices C and D, Major sublingual duct and Cystic duct, are unrelated to the Wolffian duct and are not correct answers in this context.

3. Which of the following are signs and symptoms of vaginitis EXCEPT?

• A. Vaginal itching and irritation
• B. Heavy vaginal bleeding
• C. Pain during coitus
• D. Painful urination

Correct answer: B

Rationale: Vaginitis is characterized by symptoms such as vaginal itching, irritation, pain during coitus, and painful urination. However, heavy vaginal bleeding is not typically associated with vaginitis. Vaginal bleeding could be indicative of other conditions like cervical or endometrial issues, but it is not a common symptom of vaginitis.

4. _______ 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.

5. What is a characteristic of threatening abortion?

• A. Os open.
• B. Firm contracted uterus.
• C. Heavy bleeding.
• D. Severe cramping.

Correct answer: B

Rationale: Threatening abortion is characterized by a firm contracted uterus with an open os. This presentation indicates a risk of miscarriage. Choice A ('Os open') is not specific enough and does not fully describe the condition. Choices C ('Heavy bleeding') and D ('Severe cramping') can also be present in threatening abortion, but the primary characteristic is a firm contracted uterus with an open os.
