The endometrial condition is a significant factor for successful pregnancy. To regulate endometrial function in fertility treatment, prednisolone (PSL) is administered for suppression of increased natural killer cells and stimulation of endometrium embryo transfer (SEET) to enhance communication between embryo and maternal tissues. We attempted to improve the endometrial condition by PSL admini...

Aim To evaluate the use of frozen embryos on the outcome of assisted reproductive technology (ART), a retrospective study of the Japanese Assisted Reproductive Technology Registry data during the years 2007-2012 was conducted. Methods A total of 124 946 singleton neonates who reached term gestation following ART from 2007-2012, with 80 660 achieved through frozen-thawed embryo transfer (ET) a...

Ovarian stimulation increases the risk of ovarian torsion. During an in vitro fertilization (IVF) cycle, the effects of ovarian torsion on retrieved oocytes and subsequent pregnancy chances are not clear. Moreover, no cases of ovarian torsion occurring following oocyte retrieval but prior to same-cycle embryo transfer have been reported. Such cases present a clinical dilemma with respect to opt...

Abstract Study question Is there an effect of inactivated severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccination on the outcome first frozen-thawed embryo transfer(FET) cycle. Summary answer Inactivated SARS-CoV-2 did not affect FET cycle, including clinical pregnancy rate, early miscarriage rate and newborns’ birth weight. What is known already can significantly reduce risk d...

BACKGROUND The most common complication of IVF is multiple pregnancy, which occurs in 25% of pregnancies following the transfer of two embryos. Single embryo transfer can minimize twin pregnancies but could also lower live birth rates. Our aim was to perform a systematic review of randomized trials to determine the effectiveness of single versus double embryo transfer. METHODS Cochrane Collab...

Submit Manuscript | http://medcraveonline.com for 5 years due to polycystic ovary syndrome underwent some unsuccessfully low-complexity infertility treatments, then she underwent IVF/ICSI in October 2015. The patient opted for freezing-all embryos for subsequent transfer. In June 2016, two frozen-thawed embryos were transferred in the blastocyst stage. Twelve days after the embryo transfer, the...

Abstract Study question Does embryo biopsy for preimplantation genetic testing (PGT) followed by fresh or vitrified-warmed transfer affect children’s health up to 2 years of age? Summary answer Cleavage- blastocyst-stage vitrified-warmed-embryo had neither impact on anthropometry at birth, infancy childhood nor outcomes. What is known already Literature data regarding neonatal outcomes after PG...
