Abstract Objective: To evaluate the relationship between preoperative grade and postoperative changes of semen parameters following left inguinal varicocelectomy. Methods: This study included 44 patients undergoing left microsurgical inguinal varicocelectomy. Internal spermatic veins were classified as large (4 mm or more in diameter), medium (2-2 mm), or small (2 mm or less). Changes in sperm activity, morphology and count were estimated perioperatively. The introperative findings and semen parameters were compared between varicocele groups of grades 2 and 3. Results: Both sperm motility and count improved significantly postoperatively (from (31.9±96.3)% to (47.3±35.5)%, from (28.1±18.1)×106/mL to (52.1±14.2)×106/mL). In varicoceles with grade 2 and 3, significant differences were found in the number of large veins (0.4±4.6 vs. 1.2±2.7, p < 0.001) and ultrasonographic maximum diameters of spermatic vein in supine and standing positions (2.3±3.4 cm vs. 2.8±8.6 cm, 3.1±1.7 cm vs. 3.9±9.7 cm, p=0.001 and 0.001 respectively). However no difference of changes in sperm motility and count was detected ((16.3±33.5)% vs. (14.4±42.6)%, (30.5±54.4)×106/mL vs. (12.9±90.6)×106/mL respectively, p=0.65 and 0.40 respectively). Conclusion: Preoperative varicocele grade might not predict postoperative semen changes regardless of possible existence of anatomic and ultrasonographic associations.
