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. Which of the following methods is used for permanent contraception in males?

• A. Vasectomy
• B. Tubal ligation
• C. Condoms
• D. Coitus interruptus

Correct answer: A

Rationale: The correct answer is A: Vasectomy. Vasectomy is a surgical procedure for permanent contraception in males by cutting or blocking the vas deferens. Choice B, Tubal ligation, is a method for permanent contraception in females by blocking or sealing the fallopian tubes. Choice C, Condoms, provide a barrier method of contraception but are not permanent. Choice D, Coitus interruptus, involves withdrawing the penis before ejaculation and is not a reliable method of contraception.

3. What causes the changes in appearance seen in boys at the time of puberty?

• A. Prolactin
• B. Adrenaline
• C. Estrogen
• D. Testosterone

Correct answer: D

Rationale: During puberty, boys experience physical changes such as growth of facial and body hair, deepening of the voice, and muscle development. These changes are primarily driven by the hormone testosterone. Testosterone is responsible for the development of male secondary sexual characteristics. Therefore, the correct answer is testosterone. Choices A, B, and C are incorrect because prolactin, adrenaline, and estrogen do not play a significant role in the development of male secondary sexual characteristics during puberty.

4. What is the most common site for an ectopic pregnancy?

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

Correct answer: C

Rationale: The correct answer is C, Interstitial. An ectopic pregnancy most commonly occurs in the interstitial portion of the fallopian tube. This is because the interstitial part is narrow and not suitable for the growing embryo, leading to implantation outside the uterus. Choices A, B, and D are incorrect because although ectopic pregnancies can occur in various locations, the interstitial portion of the fallopian tube is the most frequent site for such pregnancies.

5. The weight of the non-pregnant uterus is approximately ___________grams.

• A. 57
• B. 80
• C. 66
• D. 71

Correct answer: B

Rationale: The correct answer is B: 80. The non-pregnant uterus typically weighs around 80 grams. This weight may vary slightly among individuals, but 80 grams is a commonly accepted average. Choices A, C, and D are incorrect as they do not reflect the typical weight of the non-pregnant uterus. It is important to remember this approximate weight for medical reference and understanding of normal anatomical variations.
