Which of the following is the MOST common surgically correctable cause of male infertility?

• A Klinefelter syndrome
• B Congenital bilateral absence of the vas deferens
• C Varicocele ✓
• D Retrograde ejaculation

Explanation

Varicocele is present in about 40 percent of men presenting with primary infertility and is the most common surgically correctable abnormality; ligation improves semen parameters in selected patients. It is left sided in 85 to 90 percent because the left testicular vein drains perpendicularly into the renal vein. CBAVD and Klinefelter syndrome are genetic conditions not correctable by surgery, and retrograde ejaculation is managed medically rather than surgically.
