the society for assisted reproductive technology (sart) method of embryo grading is unique, simple, and widely practiced, and its use has been mandatory for sart membership programs since 2010. developed by sart in 2006, the current embryo grading system categories, “good, fair, and poor,” are limited because they do not describe the best 1-2 embryos in the interest of keeping pace with the shi...

Multiple pregnancy is a major complication of IVF and is associated with increased maternal, fetal and neonatal morbidity. Elective single embryo transfer (eSET) during IVF, rather than the more standard transfer of two embryos (double embryo transfer or DET), has been shown to significantly reduce the multiple pregnancy rate associated with IVF, while maintaining acceptable pregnancy rates. Co...

assessment of embryo quality in order to choose the embryos that most likely result in pregnancy is the critical goal in assisted reproductive technologies (art). the current trend in human in vitro fertilization/embryo transfer (ivf/et) protocols is to decrease the rate of multiple pregnancies after multiple embryo transfer with maintaining the pregnancy rate at admissible levels (according to...

BACKGROUND Elective single embryo transfer (eSET) in a selected group of patients (i.e. young patients with at least one good quality embryo) reduces the number of multiple pregnancies in an IVF programme. However, the reduced overall multiple pregnancy rate (PR) is still unacceptably high. Therefore, a randomized controlled trial (RCT) was conducted comparing eSET and double embryo transfer (D...

background: in spite of the great progress in assisted reproductive techniques ( art) and although good quality embryos are transferred pregnancy rates have remained around 30%-35% due to low implantation rates. objective: the aim of this study was to assess and compare the effects of administrating indomethacin or hyoscine suppositories prior to embryo transfer on the pregnancy rate in art cyc...

during spring, summer and winter seasons, sistani donor cows, with normal reproductive status, were superovulated and embryos were recovered non-surgically on day 7. grade a blastocyst embryos were either transferred fresh (spring) or frozen (summer and winter). recovered embryos during summer and winter were exposed to glycerol and frozen using conventional method. during spring season, recipi...

during assisted reproductive technology (art) procedures, the transfer of a single embryo dramatically reduces the rate of multiple pregnancy. proper information, therefore, should be delivered to patients before embryo transfer. in many countries, regulations limit, according to age of the patient, the number of embryos to be transferred. selective fetal reduction should not be considered as a...
