Our objective was to produce live piglets expressing the enhanced green fluorescent protein (eGFP) by the modified ICSI procedure based on Yong et al. (<jats:ext-link xmlns:xlink=\"http:\/\/www.w3.org\/1999\/xlink\" xlink:href=\"#bib39\">2003<\/jats:ext-link>) (Hum. Reprod. 18:2390) where this procedure resulted in an improvement in development in vitro as compared to conventional ICSI and IVF. After injecting frozen\u2010thawed sperm, recovered from the descendant of a transgenic boar derived by oocyte transduction, into in vitro matured oocytes the injected oocytes were surgically transferred into the oviduct of six surrogate gilts. Two gilts (33%) became pregnant. One gave birth to a healthy male piglet. Expression of the eGFP was easily observed in the nose and hooves by direct epifluorescent examination in the newborn piglet. These results show the production of the first viable transgenic piglet by in vitro maturation and our new sperm injection method. Mol. Reprod.
