Nettet1. apr. 2008 · Behavioral Analysis of Adult Mice Generated by ICSI with DFS. A complete behavioral analysis was performed in male and female CD1 and B6D2F1 mice produced by ICSI with DFS. Data were collected at 12–18 wk or 12 mo of age. Alterations in the phenotype were mainly observed in CD1 mice, with a clear sexual dimorphism. Nettetthe combination of ICSI with sperm freezing and embryo transfer is a valuable resource for a research mouse facility and its service unit. ‡ ‡ When the mouse ICSI procedure was introduced simultaneously but independently in 1995 by three research groups, microcapillaries were mostly bevelled/spiked and
