Evidence of uterine inadequacy to egg implantation in stimulated in vitro fertilization cycles


, : Evidence of uterine inadequacy to egg implantation in stimulated in vitro fertilization cycles. Fertility and Sterility 47(5): 855-857

From 104 IVF cycles 166 embryos were immediately transferred (63 embryo transfers, ET), whereas 151 embryos were frozen until later transfer (77 embryo transfers). There were 8 (12.7%) or 19 (24.7%) pregnancies after fresh or frozen-thawed ET, respectively. Sixteen pregnancies (29.1%) originated from 55 ETs of frozen-thawed embryos coming from IVF cycles in which pregnancy was not induced by fresh ET. The pregnancy rate after fresh ET (10.5%) was lower than that obtained when the same patients received frozen-thawed embryos (27.1%, P less than 0.02). It is concluded that a normal pregnancy rate may result if the embryos originating from an unsuccessful IVF-ET cycle are transferred in a favorable uterus.
