Abstract
This study was conducted to investigate the effects of various factors of practitioner's techniques such as skill, difficulty, consumed time, implantation depth, bleeding and altering of implant location, on pregnancy and abortion after transfer of in vitro produced Korean Native Cow embryos. The pregnancy rate of skilled transfer $(54.2\%)$ was significantly higher than that of unskilled transfer $(37.9\%)$, of 2/3 $(46.9\%)$ location in uterus was significantly higher than in 1/2 $(39.5\%)$ or 4/5 $(38.0\%)$ uterus, and of altering implantation location $(52.9\%)$ was significantly increased. There were no difference in pregnancy among the groups of difficulty of transfer, consumed time and bleeding of uterus. The abortion rates from skill, difficulty of transfer, implantation depth, consumed time, bleeding of uterus and altering of location were not differ.
