Patients In the study group (povidone iodine group) patients will be prepared with vaginal cleansing with povidone-iodine along with the usual abdominal scrub. Vaginal cleansing will be done with 3 gauze pieces soaked with 10% povidone iodine in a sterilized bowl and the scrub will be done from the vaginal apex to introitus with attention to the anterior, posterior and lateral vaginal wall. After vaginal cleansing the gloves will be changed to perform the abdominal scrub.
