Table 5. Comparison of fresh motile and frozen-thawed motile sperm in chromosome aberrations

Sperm Injected	No. of Males Used	No. of Ejaculates Used	No. of Oocytes Karyotyped	Sperm With Structural Aberrations,* % (Median ± SEM)	Sperm With Aneuploidy,* % (Median ± SEM)

Fresh motile	5	15	164	5 (3.14 ± 1.37)	8 (4.96 ± 1.53)
Frozen-thawed motile	5	15	154	8 (4.92 ± 1.52)	8 (5.26 ± 0.77)

*P > .05 in percentage of sperm with structural aberrations, percentage of sperm with aneuploidy, and X:Y sex ratio.
