Predictors of varicocele-associated pain and its impact on semen parameters following microsurgical repair.

Our study aimed to assess for predictors of varicocele-associated pain and whether it predicts semen parameters after microsurgical varicocelectomy. We assessed all men diagnosed with a varicocele by two surgeons from 2017 to 2020, excluding those who did not undergo surgical treatment. Patients were stratified based on the presence of pain at clinical assessment, and these groups were compared. Logistic regression models were utilised to assess for predictors of pain. A total of 313 men were included, with relatively similar proportions completed by both surgeons (48.2% and 51.8%). A total of 98 (31.3%) had typical varicocele-associated pain at the time of assessment. The pain group was younger than the no pain group (30.5 versus. 35.0, respectively, p < .01), and those with pain had greater varicocele grades (p = .008). Although not statistically different, there was a greater portion of left-sided only varicoceles in the pain group (p = .09). No significant differences were demonstrated between sperm concentration, motility, volume or morphology pre-operatively, or post-operatively between groups. Younger age and varicocele grade were predictive of varicocele-associated pain. In conclusion, almost 1/3 of men presented with varicocele-associated pain. Pain does not predict response to varicocelectomy, but these men tend to be younger, and have higher grade varicoceles.
