Which of the following statements is correct?
- A. Follicle stimulating hormone secreted from the hypothalamus stimulates spermatogenesis in the Sertoli cells.
- B. Luteinizing hormone secreted from the hypothalamus stimulates the release of testosterone from the Leydig cells.
- C. Leydig cells secrete testosterone which stimulates spermatogenesis in the Sertoli cells.
- D. Leydig cells secrete inhibin
Correct Answer: C
Rationale: Rationale:
C is correct because Leydig cells in the testes secrete testosterone, which is essential for stimulating spermatogenesis in the Sertoli cells. Testosterone plays a crucial role in the development and maturation of sperm. A is incorrect because follicle stimulating hormone is secreted by the pituitary gland, not the hypothalamus. B is incorrect because luteinizing hormone is secreted by the pituitary gland, not the hypothalamus. D is incorrect because Leydig cells primarily secrete testosterone, not inhibin.

Regarding gross anatomy of male reproductive system
- A. Dartos muscle is responsible to raise and lower the testes
- B. Ductus deferens penetrate the prostate gland to connect with prostatic urethra
- C. Anterior lobe of prostate gland is the main glandular tissue
- D. Buck's fascia encloses body of penis
Correct Answer: B
Rationale: The correct answer is B because the ductus deferens penetrates the prostate gland to connect with the prostatic urethra, forming the ejaculatory duct. This allows for the transport of sperm from the epididymis to the urethra during ejaculation.
A: Dartos muscle is responsible for wrinkling the scrotal skin but not raising and lowering the testes.
C: The anterior lobe of the prostate gland mainly consists of fibromuscular tissue, not glandular tissue.
D: Buck's fascia surrounds the corpora cavernosa and the corpus spongiosum of the penis, not the body of the penis itself.
The process of release of ovum from the ovary is termed as
- A. Dessication
- B. Ovulation
- C. Fenestration
- D. Maturation
Correct Answer: B
Rationale: The correct answer is B: Ovulation. Ovulation is the process of the release of the mature egg (ovum) from the ovary. During ovulation, the egg is released into the fallopian tube where it can potentially be fertilized by sperm. Dessication (A) refers to the process of drying out, Fenestration (C) is the creation of an opening or hole, and Maturation (D) is the process of becoming mature. Therefore, the correct term specifically related to the release of the egg from the ovary is ovulation.

From fertilization to week 8 of proliferative phase of the uterine pregnancy, the conceptus is called (menstrual) cycle? ________.
- A. estrogens
- B. a fetus
- C. progesterones
- D. an embryo
Correct Answer: D
Rationale: The correct answer is D: an embryo. From fertilization to week 8 of the proliferative phase of uterine pregnancy, the conceptus is referred to as an embryo. This is because during this period, the fertilized egg undergoes rapid cell division and differentiation, leading to the formation of distinct embryonic structures and the beginning of organ development. The term "fetus" is used after the embryonic stage, typically from week 9 onwards. Choices A and C, estrogens and progesterones respectively, are hormones involved in regulating the menstrual cycle and maintaining pregnancy but are not terms used to describe the developing conceptus itself during this specific timeframe.
