  • Data are shown as the estimated linear regression statistic beta, SE and P value using an additive genetic model with adjustments for age, BMI, ejaculation abstinence and time from masturbation to test.

  • *Var (%): percentage of phenotypic variance explained by SNP.

  • BMI, body mass index; Chr, chromosome; EAF, effect allele frequency; GWAS, genome-wide association study; SNP, single nucleotide polymorphism.
