BIOD 152 Module 6: Reproductive System, Spermatogenesis,
Oogenesis, and Pregnancy 2026/2027 UPDATE
1. Where does spermatogenesis specifically occur within the testes?
A. Interstitial cells
B. Seminiferous tubules
C. Epididymis
D. Rete testis
Answer: B
Rationale: Spermatogenesis occurs within the seminiferous tubules of the testes, where
sperm cells are produced from spermatogonia.
2. Which hormone is responsible for stimulating the interstitial (Leydig) cells to
produce testosterone?
A. FSH
B. LH
C. GnRH
D. Inhibin
Answer: B
Rationale: Luteinizing Hormone (LH) targets the interstitial cells to secrete testosterone,
whereas FSH targets Sertoli cells to support sperm production.
,3. At what stage of development is the oocyte arrested in until ovulation
occurs?
A. Anaphase I
B. Metaphase II
C. Prophase I
D. Prophase II
Answer: C
Rationale: Primary oocytes begin meiosis I during fetal development but remain arrested
in Prophase I until puberty, when one resumes development each month.
4. Which structure in the female reproductive system is the most common site
for fertilization?
A. Uterus
B. Cervix
C. Fallopian tubes
D. Ovaries
Answer: C
Rationale: Fertilization typically occurs in the ampulla of the Fallopian (uterine) tubes.
5. What is the primary function of the acrosome of a sperm cell?
A. Provide energy for movement
B. Contain the genetic material
C. Contain enzymes to penetrate the egg
D. Propel the sperm forward
Answer: C
Rationale: The acrosome is a cap-like structure containing digestive enzymes that allow
the sperm to penetrate the zona pellucida of the oocyte.
, 6. During the ovarian cycle, a surge in which hormone triggers ovulation?
A. Estrogen
B. Progesterone
C. FSH
D. LH
Answer: D
Rationale: A sharp rise or surge in Luteinizing Hormone (LH) around day 14 of the cycle
causes the mature follicle to rupture and release the egg.
7. What is the name of the structure that remains after ovulation and secretes
progesterone?
A. Corpus luteum
B. Corpus albicans
C. Graafian follicle
D. Primary follicle
Answer: A
Rationale: After ovulation, the ruptured follicle transforms into the corpus luteum, which
secretes progesterone to maintain the uterine lining.
8. Which layer of the uterus is shed during menstruation?
A. Myometrium
B. Perimetrium
C. Stratum basalis
D. Stratum functionalis
Answer: D
Rationale: The stratum functionalis of the endometrium is the functional layer that builds
up and breaks down during the menstrual cycle.
