ResumoA technique for rapid and repeated laparoscopic ovarian examination was developed for use in the sheep. A midventral approach was used on ewes under general anesthesia on a 45-degree sloped table. Examination could be done as often as every other day. The technique was used for detection of ovulation in studies of gonadotropin stimulation in anestrous ewes. Ovulation was induced with 5 to 10 mg FSH and 100 to 2000 iu HCG. The use of laparoscopy in pregnancy diagnosis was also investigated. Accurate diagnosis could be made by Day 17 using both uterine and ovarian characteristics. Visualization through the laparoscope was utilized for aspiration of follicular oocytes using a 23 ga, 11 cm needle.
