Men undergoing varicocele repair (surgical or embolization) were identified via a prospectively collected database. The relationship of pre-repair sem*n and clinical characteristics to improvements in sem*n parameters was modeled using multivariable linear regression, then the model performance was quantified by concordance correlation coefficient and Pearson correlation coefficient after internal validation with bootstrapping.

Regarding the article you mentioned, it discusses the formulation of nomograms based on pre-repair characteristics to predict improvements in sem*n parameters after varicocele repair. The study used a multivariable linear regression model based on a prospectively collected database to develop the nomograms. The performance of the model was quantified using concordance correlation coefficient and Pearson correlation coefficient after internal validation with bootstrapping. The study was conducted at a male infertility specialty clinic and included men who underwent varicocele repair between 2003 and 2012. The researchers analyzed the relationship between pre-repair sem*n and clinical characteristics and improvements in sem*n parameters after the repair.
