The correlates of postoperative disorders were analyzed on the 556 cases of swine embryo recovery performed during the last eight years. The total number of wasted embryo donors was 127. Forty point nine percent of them were wasted by the adhesion of reproductive organs. Eleven percent were wasted by reproductive disorders such as anovulation and anaphrodisia, and 5.5% were wasted by infectious disorders such as purulence and endometritis. As the adhesion of reproductive organs was the most frequent reason for wastage, it was analyzed in detail. Out of the 330 cases that were operated more than two times as embryo donors, 52 cases (15.8%) were in severe adhesion. When the total experimental period was divided into three phases, the incidents of adhesion decreased in phase by phase. It was presumed that this results from the improvement of operating methods, skills and equipments. It was suggested that ovarian cyst was related to the high dose of PMSG.
