Varicocele Flashcards
Question 1: Classification of Varicoceles
Topic: Varicocele Classification
Question:
A 32-year-old male patient comes for a fertility evaluation and during the physical exam, a varicocele is palpable only with Valsalva maneuver. How would you classify this varicocele?
Options:
A) Grade I
B) Grade II
C) Grade III
D) Subclinical varicocele
Correct Answer: A) Grade I
Explanation:
A Grade I varicocele is palpable only with Valsalva maneuver. Grade II is palpable in the standing position, and Grade III is visible without palpation. Subclinical varicocele is detected only on Doppler ultrasound of the scrotum.
Memory Tool:
Think of “Grade I” as “Invisible until Valsalva” to help remember that you need the Valsalva maneuver to detect it.

Question 2: Impaired Fertility Mechanisms in Varicocele
Topic: Mechanisms of Impaired Fertility
Question:
Which of the following is NOT a mechanism by which varicoceles impair fertility in men?
Options:
A) Venous pooling leading to increased scrotal temperature
B) Hypoperfusion and hypoxia due to venous reflux
C) Impaired Leydig cell function leading to low intratesticular testosterone
D) Impaired Sertoli cell function leading to elevated intratesticular testosterone
Correct Answer: D) Impaired Sertoli cell function leading to elevated intratesticular testosterone
Explanation:
Varicoceles impair fertility through various mechanisms including venous pooling leading to increased scrotal temperature, hypoperfusion and hypoxia due to venous reflux, and impaired Leydig cell function leading to low intratesticular testosterone. There is no evidence suggesting that varicoceles lead to elevated intratesticular testosterone.
