Nonsurgical technique for flushing the Macaca mulatta uterus

The tortuous structure of the rhesus cervix has proven to be a significant obstruction to performing nonsurgical uterine lavage. Trials were conducted to develop a repeatable, nonsurgical flushing technique of the uterus. Using a modified endometrial cell sampler and a blunt trocar, a reliable technique was constructed. This technique may prove valuable for conducting nonsurgical recovery of embryos and for repeated atraumatic sampling of the rhesus uterus.
