Vissers J, Sluckin TC, van Driel-Delprat CCR, et al. - Researchers examined the effect of a previous cesarean section on reproductive outcomes, including live birth, in women after IVF or ICSI. From the IVF Center, Amsterdam UMC, location VUmc, Amsterdam, the Netherlands, they assessed the live birth rate in women who had an IVF or ICSI treatment between 2006 and 2016 with one previous delivery. They included 1,317 women; of these, 334 had a previous cesarean section and 983 had previously delivered vaginally. They observed lower clinical pregnancy rates per embryo transfer in women with a previous cesarean section indicating that a cesarean section hampers implantation.
