Marker-trait association analysis and clinical parameters of the two study samples stratified into subgroups based on the FSHR -29G/A (rs1394205) genotypes of the participants.

aBaltic young men cohort, n = 982, A-allele frequency 25.4%, HWE test P = 0.40; Estonian oligozoospermic men, n = 641, A-allele frequency 22.9%, HWE test P = 1.0.bFSHR -29 A-allele effect is shown as the estimated linear regression (additive model) statistic beta (β), standard error of the regression (SE) is shown in brackets.
