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.

본 연구는 임상 조건하에서 수정란이식의 효율성 증대를 위하여 이식 시술자 측면의 숙련도, 난이도, 소요시간, 주입 위치, 자궁의 출혈 및 위치 조절이 체외수정란이 이식된 수란우의 임신과 유산에 미치는 효과를 검토하였다. 임신율은 숙련된 시술자$(54.2\%)$, 자궁각 2/3 지점에 이식$(46.9\%)$ 및 위치 조절군$(52.9\%)$이 유의하게 높은 경향이었으나, 이식 난이도, 소요시간 및 출혈에 따른 차이는 인정되지 않았다. 한편 시술자 측의 요인에 따른 유산율은 유사한 경향이었다.
