Randomization will be obtained via computer generation in consecutively numbered, opaque sealed envelopes with the name of one of the suture materials. The envelope will be opened at the time of repair of perineal laceration once inclusion criteria have been met by the physician or midwife performing the laceration repair. Repair with the chosen suture will be performed using the continuous suture technique using a 3-0 suture, which is current standard practice. Patients will not be informed of the type of suture used, although the type of suture will be recorded in the patient's electronic medical record. Various maternal and fetal characteristics will be recorded including maternal age, gravity and parity, gestational age at delivery, birth weight, mode of vaginal delivery (spontaneous or operative) and whether the patient had pre-pregnancy dyspareunia.
