We aimed to evaluate the presence of retrograde flow and if present the Peak Retrograde Flow (RPF) after varicocelectomy in adolescents. We also investigated its relation with catch-up growth, Total motile sperm count, and potential paternity. MATERIAL AND METHODS The study involved 126 adolescent patients with a mean age of 13.9 years (range, 10.7 to 18 years) who underwent subinguinal varicocelectomy between 2006–20016. Indication for surgery was asymmetric testicular growth>20 %, PRF>35 cm/s and pain with grade 3 varicocele. Post- operatively, patients were evaluated both clinically and sonographically for recurrence and testicular volume. Catch-up growth was also compared in patients with significant pre-operative asymmetry at a mean of the postoperative period of 16.3 (9–36) months. Mean follow up was 4.7 years (1–8.2 years). At least one Semen analysis was performed in patients with Tanner V during the follow-up period. All patients above 18 were phoned to determine the paternity for the study. RESULTS 96 of our patients (76 %) showed catch-up growth on follow up. 56 patients (44 %) showed PRF>20 cm/s on follow up. 35 of these patients had PRF 20–35 cm/s and 21 patients had a PRF>35 cm/s. Catch-up growth showed statistically no significant difference between high and low-pressure peak retrograde flow groups. TMC in patients with PFR >35 cm/s was significantly lower. Only 4 patients out of 56 patient with a retrograde flow above 20 cm7sn reported paternity and 1 was in the PFR >35 cm/sn group. CONCLUSIONS Despite the presence or absence of catch up growth, PRF above 35 cm/s should be taken as the definition of recurrence after varicocelectomy in adolescents. However, this still can not properly predict paternity.
