Subtopic 1: Male and Female Reproductive Anatomy and
Physiology
Question 1:
Which structure is responsible for the production of testosterone in males?
A. Prostate gland
B. Leydig cells
C. Sertoli cells
D. Epididymis
Rationale:
Leydig cells, located in the interstitial tissue of the testes, produce testosterone in
response to luteinizing hormone (LH). Sertoli cells support sperm development, but they
do not produce testosterone.
Question 2:
What is the primary function of the corpus luteum?
A. To release estrogen continuously
B. To secrete progesterone and maintain the uterine lining
C. To stimulate ovulation
D. To produce luteinizing hormone
Rationale:
After ovulation, the follicle becomes the corpus luteum, which secretes progesterone to
maintain the uterine lining in preparation for potential implantation.

Question 3:
The hormone responsible for triggering ovulation is:
A. Estrogen
B. Luteinizing hormone (LH)
C. Follicle-stimulating hormone (FSH)
D. Progesterone
Rationale:
A surge in luteinizing hormone (LH) mid-cycle triggers the release of a mature egg from the
ovary, marking ovulation.
Question 4:
Which structure in the female reproductive system is the usual site of fertilization?
A. Uterus
B. Cervix
C. Fallopian tube
D. Ovarian follicle
Rationale:
Fertilization typically occurs in the ampulla of the fallopian tube, where the sperm meets
the ovum.
Question 5:
Spermatogenesis primarily occurs in which part of the testes?
, 4
A. Rete testis
B. Epididymis
C. Seminiferous tubules
D. Vas deferens
Rationale:
The seminiferous tubules are tightly coiled structures within the testes where
spermatogenesis (sperm production) occurs.
Question 6:
Which of the following is NOT a function of estrogen?
A. Development of female secondary sexual characteristics
B. Regulation of the menstrual cycle
C. Maintenance of pregnancy in the second trimester
D. Thickening of the endometrial lining
Rationale:
Estrogen plays a role in secondary sexual development and menstrual cycle regulation.
Progesterone, not estrogen, primarily maintains pregnancy during the second trimester.
Question 7:
Which hormone stimulates the development of ovarian follicles?
A. Follicle-stimulating hormone (FSH)
B. Luteinizing hormone
