SECTION 1: MALE REPRODUCTIVE SYSTEM Q1 – Q13
══════════════════════════════════════
Question 1 of 50
A 42-year-old male presents with a palpable mass in his scrotum that does not transilluminate.
During physical exam, the mass feels separate from the testis and has a worm-like consistency.
The patient denies pain and reports gradual enlargement over several months. Which structure is
most likely involved in this finding?
A. Tunica vaginalis
B. Epididymis ✓ Correct Answer
C. Spermatic cord
D. Tunica albuginea
Correct Answer: B
Rationale: A painless, worm-like mass separate from the testis that fails to transilluminate is
classic for an epididymal cyst or spermatocele, both arising from the epididymis. The spermatic
cord would present as a more diffuse cord-like swelling rather than a discrete worm-like mass.

Epididymal abnormalities are common in middle-aged men and are typically benign, though any
new scrotal mass warrants ultrasound confirmation.
Question 2 of 50
During a vasectomy, a surgeon must identify and ligate the correct duct to prevent sperm from
entering the ejaculate. A 35-year-old patient asks which structure carries sperm from the
epididymis toward the ejaculatory duct. The surgeon explains that this tube travels through the
inguinal canal as part of the spermatic cord.
A. Ductus deferens ✓ Correct Answer
B. Ejaculatory duct
C. Urethra
D. Efferent ductules
Correct Answer: A
Rationale: The ductus deferens (vas deferens) ascends from the epididymis, passes through the
inguinal canal within the spermatic cord, and eventually joins the duct of the seminal vesicle to
form the ejaculatory duct. The ejaculatory duct is the short terminal union formed inside the
prostate, not the long transport tube through the inguinal canal. Understanding this pathway is
essential for both vasectomy procedures and identifying the route of sperm transport.
Question 3 of 50
A 28-year-old male athlete sustained a direct blow to the groin during a soccer match. Imaging
reveals rupture of the fibrous capsule surrounding each testis. This capsule also sends inward
projections that divide the testis into lobules. Which structure has been damaged?
A. Tunica vaginalis
B. Cremasteric fascia
C. Tunica albuginea ✓ Correct Answer
D. Dartos muscle
Correct Answer: C
Rationale: The tunica albuginea is the dense fibrous capsule of the testis that gives it shape and
sends septal extensions inward to create approximately 250 lobules. The tunica vaginalis is the
serous outer covering derived from the peritoneum and does not form internal septa. Trauma to
the tunica albuginea can cause testicular rupture, a urologic emergency requiring surgical repair
to preserve testicular function.

Question 4 of 50
A 19-year-old college student is diagnosed with a varicocele affecting the pampiniform plexus on
the left side. His physician explains that this venous network serves an important
thermoregulatory function for spermatogenesis. Which specific mechanism best describes this
physiological role?
A. Cooling arterial blood before it reaches the testis ✓ Correct Answer
B. Warming venous blood returning from the testis
C. Filtering testosterone from venous return
D. Storing sperm during ejaculation
Correct Answer: A
Rationale: The pampiniform plexus functions as a countercurrent heat exchanger, cooling the
warmer arterial blood from the testicular artery as it descends toward the testis, thereby
maintaining the cooler temperature required for spermatogenesis. Warming venous blood would
be counterproductive to the testis's need for temperatures 2–3°C below core body temperature.
Varicoceles disrupt this cooling mechanism and are a leading cause of male infertility due to
elevated scrotal temperatures.
Question 5 of 50
A histology student examining a testicular cross-section notices that each seminiferous tubule
contains cells at various stages of development, with the most mature forms positioned nearest
the lumen. Which cell type represents the final differentiated product released into the lumen
during spermiation?
A. Spermatogonia
B. Primary spermatocytes
C. Spermatids
D. Spermatozoa ✓ Correct Answer
Correct Answer: D
Rationale: Spermatozoa are the fully mature, flagellated gametes that are released from Sertoli
cells into the tubule lumen during spermiation, the final step of spermatogenesis. Spermatids are
haploid cells that still require spermiogenesis to undergo structural remodeling before becoming
functional sperm. Understanding this maturation sequence is fundamental to interpreting semen
analysis and identifying causes of oligospermia.
