Descripción:	The present study evaluated embryo development and transgene expression after lentiviral microinjection into perivitelline space of early zygotes (6 h post in vitro fertilization) or matured oocytes. In a preliminary experiment we evaluated the effect of short incubation period and of sperm concentration on embryo development. In vitro matured oocytes (n = 591, five repetitions) were co-incubated with 2 or 4 million sperm/mL for 6 or 20 h and cleavage and blastocyst rate were analyzed by Chi square. Higher (P\0.05) cleavage rate was obtained with 4 million sperm for 20 h whereas the blastocyst rate at day seven post-insemination was similar (P\0.05) between 4 million sperm for 6 and 20 h.
