Mitochondrial DNA in Fresh versus Frozen Embryo Culture Media of Polycystic Ovarian Syndrome Patients Undergoing Invitro Fertilization: A Possible Predictive Marker of a Successful Pregnancy.

Purpose: Frozen embryos transfer (ET) may improve the live-birth and reduce rates of ovarian hyperstimulation in polycystic ovary syndrome (PCOS) patients. Morphological criteria are the classical way for embryo selection, yet recently, many biochemical and genetic markers have been developed. This study aimed to compare fresh and frozen ET using the mtDNA/gDNA ratio of embryo secretome and the possibility of using this ratio as a predictive marker of PCOS pregnancy rate.

Multicenter randomized controlled trial assessing the impact of a cervical traction maneuver (Amr's maneuver) on the incidence of postpartum hemorrhage.

Objective: To assess the impact of a cervical traction maneuver (Amr's maneuver) used in conjunction with active management of the third stage of labor (AMTSL) on the incidence of postpartum hemorrhage (PPH).

Method: The present multicenter randomized controlled trial was conducted in Cairo between March 1, 2016, and June 30, 2017. Women aged at least 18 years who had singleton pregnancies and were candidates for vaginal delivery were enrolled.
