In-vitro fertilization is associated with a high rate of multiple pregnancies, a consequence of the number of embryos transferred. There is a challenge in avoiding even twin pregnancies in assisted reproduction, and this can be accomplished with elective single embryo transfer and a good cryopreservation programme. In our follow-up study, we analysed all our elective single embryo transfers dur...
Poor oocyte quality is a main concern for decreased reproductive outcomes in women with polycystic ovarian syndrome (PCOS) during controlled ovarian hyperstimulation (COH). A primary way to improve oocyte quality is to optimize the COH protocol. It was demonstrated that the viable embryo rate per oocyte retrieved in the Utrogestan and hMG protocol, a novel regimen based on frozen-thawed embryo ...
INTRODUCTION Pregnancy rates after frozen embryo transfer (FET) have improved in recent years and are now approaching or even exceeding those obtained after fresh embryo transfer. This is partly due to improved laboratory techniques, but may also be caused by a more physiological hormonal and endometrial environment in FET cycles. Furthermore, the risk of ovarian hyperstimulation syndrome is pr...
BACKGROUND The risks of premature birth and perinatal death are increased after in vitro fertilization. These risks are mainly due to the high incidence of multiple births, which relates to the number of embryos transferred. METHODS We performed a randomized, multicenter trial to assess the equivalence of two approaches to in vitro fertilization with respect to the rates of pregnancy that res...
Objectives: To compare the clinical outcomes of single fresh and frozen-thawed superior blastocyst transfer in patients for the first transfer. Methods: This study included 770 single fresh blastocyst and 639 single frozenthawed blastocyst transfers from January 2013 to January 2016. All the fresh and frozen-thawed embryo transfer was first transfer for the patients. The patients were divided i...
STUDY QUESTION Is there a different risk for major congenital anomalies (CAs) in children born after frozen-thawed embryo transfer (FET) compared with children born after fresh embryo transfer (ET)? SUMMARY ANSWER Children born after FET have a similar risk of developing major CAs as children born after fresh ET. WHAT IS KNOWN ALREADY The perinatal outcome in children born after FET is as g...
OBJECTIVE To evaluate the effect of hyaluronan-rich transfer medium on pregnancy and implantation rates in fresh and frozen-thawed embryo transfers in Korean women with previous implantation failure. METHODS This retrospective study included 283 blastocyst transfers in patients with previous embryo transfer failure at a private fertility clinic. In the study group (n=88), blastocyst transfers...
