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. Practices such as female genital mutilation and unsafe male circumcision are categorized as:

• A. Harmful traditional practices
• B. Encouraged in rural Zambia
• C. Recommended in modern surgery and IRH
• D. Safer sex practices

Correct answer: A

Rationale: Practices like female genital mutilation and unsafe male circumcision are considered harmful traditional practices due to the physical and psychological harm they cause. Choice A is correct as these practices are not safe or recommended. Choice B is incorrect, as harmful traditional practices are not encouraged anywhere. Choice C is incorrect as modern surgery and organizations like IRH aim to eliminate such practices, not recommend them. Choice D is incorrect as these practices are not related to safer sex practices but rather harmful practices that need to be eradicated.

3. Where does fertilization normally occur?

• A. Ampulla
• B. Interstitial portion
• C. Isthmus
• D. Infundibulum

Correct answer: A

Rationale: Fertilization typically occurs in the ampulla of the fallopian tube. The ampulla provides the ideal environment for fertilization due to the presence of cilia that help transport the egg and sperm, as well as the nourishing fluid within this region. The interstitial portion, isthmus, and infundibulum of the fallopian tube are not the primary sites for fertilization. The interstitial portion connects the fallopian tube to the uterine cavity, the isthmus is the narrowest part near the uterus, and the infundibulum is the funnel-shaped end near the ovary, where the egg is captured after ovulation.

4. How does human sperm move?

• A. Flagella
• B. Cilia
• C. Neutrophils
• D. None of the above

Correct answer: A

Rationale: Human sperm moves using flagella, which are whip-like structures that aid in propulsion. Flagella are tail-like structures found in sperm cells and help them swim towards the egg for fertilization. Cilia are shorter, hair-like structures that are not involved in the movement of sperm. Neutrophils are a type of white blood cell involved in the immune response and are not related to sperm locomotion.

5. What is one role of the hormone estrogen?

• A. Stimulates the development of the milk-producing tissue.
• B. Stimulates the production of lactoferrin.
• C. Stimulates the development of the nipple and duct system in the breast.
• D. Stimulates the secretion of relaxin.

Correct answer: A

Rationale: The correct answer is A: Estrogen stimulates the development of the milk-producing tissue in the breast. This hormone is essential in preparing the breast for milk production. Choice B is incorrect because lactoferrin production is not a primary role of estrogen. Choice C is incorrect as estrogen primarily influences the development of the breast tissue rather than specifically the nipple and duct system. Choice D is incorrect because relaxin secretion is not a function typically associated with estrogen.
