Cesarean scar defects (CSDs), i.e. deficient uterine scars following a cesarean section, involve discontinuity at the site of a previous Cesarean section scar. These anatomical defects have been reported to be associated with postmenstrual spotting, chronic pelvic pain and infertility. Few case series have suggested improved fertility (most probably by improving implantation of embryos) The aim of this study is to prospectively record embryonal implantation rate during IVF in patients with CSDs, and to evaluate the effect of hysteroscopic repair of CSDs on fetal implantation during IVF.
150 patients undergoing IVF after cesarean section will be recruited. demographic, clinical and treatment data will be collected. ultrasound and hysteroscopic evaluation of the CSD will be performed. IVF treatment will be provided. In case of failure of IVF treatment, patients will be randomized to hysteroscopic repair of CSD versus second IVF treatment

Operative hysteroscopy for the repair of cesarean section defect is performed under general anesthesia. the cervix is dilated and the cesarean section defect opened. polypoid tissue is ablated
Betthochi's method for diagnostic hysteroscopy: No anesthesia will be used. vaginoscopy will be performed, followed by diagnostic hysteroscopy. saline will be used as a distension media. 4.2 mm Storz hysteroscope will be used.
Scanning the uterus with the ultrasound probe . Transvaginal ultrasound usually produces better and clearer images of the female pelvic organs, because the ultrasound probe lies closer to these structures. The transvaginal ultrasound probe is thin, about 2cm diameter. The probe is covered with a disposable protective sheath. A small amount of ultrasound gel is placed on the end of this probe. The probe is then gently inserted a short distance into the vagina.
