Jang WS, Kim KH, Lim KT, et al. - This study was intended to confirm the Samplaski's post‐varicocele repair semen analysis nomogram to validate the predictive accuracy of total motile sperm count. Researchers enrolled a sum of 300 individuals who underwent varicocelectomy between July 2016 and July 2019 from 4 treatment centres in this validation cohort study. It was illustrated that calibration plot revealed that the discrepancy between the predicted and observed total motile sperm count was plausible. Nevertheless, it had low explanatory power in this nomogram model. The post‐varicocele repair Samplaski's nomogram prognosticates a relatively lower total motile sperm count than the observed count in this validation study.
