title: Effect of serial intrauterine dimethyl sulfoxide infusions on the incidence of periglandular fibrosis in category II horse endometria.
abstract: High concentrations of dimethyl sulfoxide (DMSO) have been shown to cause gross structural changes in collagen fibers in vitro. As endometrial fibrosis is a major cause of infertility in mares, the effect of serial DMSO infusions on periglandular fibrosis of Category II endometria was investigated. Initially, six mares with Category I endometria were serially infused with DMSO to determine whether such therapy would incite fibrosis. Four mares, serially infused with saline, served as controls in each experiment. One hundred milliliters of 75% DMSO was infused initially, followed by the same volume of 25% DMSO daily for 6 d. Endometrial biopsies obtained 21 d after the last infusion displayed no significant difference in the incidence of periglandular fibrosis when compared with the Day 0 biopsies. Examination of treated uteri at necropsy showed no gross evidence of adhesions or ulcerations.
