Table 3.

Means (and standard deviations) of sperm concentration of gr/gr deleted and gr/gr deleted – b2/b4 duplicated (single or multiple) men, classified on the basis of the type of missing DAZ and CDY1 copies. The means of sperm concentration in these gr/gr rearrangements, further divided on the basis of the deletion subtype, are also shown. Deletion subtypes remove: 1) DAZ1/DAZ2+CDY1a; 2) DAZ3/DAZ4+CDY1a; 3) DAZ1/DAZ2+CDY1b; 4) DAZ3/DAZ4+CDY1b.
