The 6 recurring CNVs with significantly different (P*; percentage in brackets) between patients with oligozoospermia or SCOS and normozoospermia or between SCOS and both other groups combined.

For comparison, the corresponding duplication/deletion (if present in any group) is included independent of P-value. CNVs were checked for occurrence in the Database of Genomic Variants (DGV).*If CNVs were only found by higher-resolution 400K-array, the number of all cases is reduced to 22 for normozoospermic controls and to 47 for patients with severe oligozoospermia (see methods).SCOS = Sertoli-cell-only syndrome. P-values calculated by Fisher's exact test. To correct for multiple testing, P-level for significance was adjusted according to the Bonferroni-Holm procedure.
