Paternal effect on genomic activation, clinical pregnancy and live birth rate after ICSI with cryopreserved epididymal versus testicular spermatozoa

Table 3 Development of embryos not transferred or frozen on Day 3

	Epididymal	Testicular OA	Testicular NOA
Number of embryos	349	224	48
Embryos undergoing compaction	74%	69%	79%
Embryos undergoing blastulation	38%	42%	38%

Comparison of embryos derived from ICSI with epididymal sperm and testicular sperm (obstructive azoospermia;OA) and non-obstructive azoopermia (NOA). Development expressed as percentage of total embryos left in extended culture. No significant differences were observed.
