A description is given of a technique devised to allow repeated endoscopic observations to be made of ovarian changes occurring during an oestrous cycle in the ewe. The use of a chronic peritoneal fistula is illustrated and the methods used to maintain its patency are discussed. The technique was carried out in a small number of ewes and the ovarian changes occurring over a 22-day period in an ovary of one of these ewes are shown in photographic and diagrammatic form.
