Women undergoing in vitro fertilization (IVF) therapy, who are low responder and agree to enter the trial will be randomized to a study group, for whom embryo transfer will be done on the same day as oocyte aspiration and fertilization; and a control group for whom embryo transfer will be performed 48 to 72 hours later, as is the current accepted practice.
Allocation: Randomized, Intervention Model: Parallel Assignment, Masking: Open Label, Primary Purpose: Treatment

The purpose of this study is to evaluate two types of embryo transfer procedure. The investigators will compare direct embryo transfer against afterloading embryo transfer.
The purpose of this study is to determine whether embryo transfer on day 3 versus day 5 shows a significant difference in implantation, clinical pregnancy, live birth, miscarriage and mult...
This study is a prospective randomized controlled trial to compare the pregnancy outcomes of frozen embryo transfer in natural and hormonal replacement cycles. The study population consist...
The objective of the present randomized controlled study is to compare clinical effectiveness and safety of freezing all embryos followed by frozen-thawed embryo transfer (FET) compared to...
The number of copies of mitochondrial genes (mtDNA or "MitoScore") is related to the energy supply of the embryo, which can affect its ability to implant in the maternal uterus. The objec...
Single embryo transfer (SET) has been recommended to avoid multiple births following assisted reproductive technology (ART) procedures. Many studies have shown that frozen embryo transfer may yield be...
Catheter injection speed affects depth and placement of the embryo into the uterine cavity and is shown to be highly variable in, and between, subjects in a manually performed embryo transfer. In an e...
The purpose of this study was to determine the optimal endometrial preparation protocol by comparing the clinical outcome of two methods of endometrial preparation in frozen-thawed embryo transfer (FE...
Frozen-thawed (FT) embryo transfer is a procedure used for the storage and transfer of excess embryos obtained during in vitro fertilization- intracytoplasmic sperm injection cycles. In recent years, ...
The use of assisted reproductive technology (ART) is increasing in the world. The rate, efficacy and safety of ART are very different among countries. There is an increase in the use of intra cytoplas...
A medical-surgical specialty concerned with the morphology, physiology, biochemistry, and pathology of reproduction in man and other animals, and on the biological, medical, and veterinary problems of fertility and lactation. It includes ovulation induction, diagnosis of infertility and recurrent pregnancy loss, and assisted reproductive technologies such as embryo transfer, in vitro fertilization, and intrafallopian transfer of zygotes. (From Infertility and Reproductive Medicine Clinics of North America, Foreword 1990; Journal of Reproduction and Fertility, Notice to Contributors, Jan 1979)
The techniques used to select and/or place only one embryo from FERTILIZATION IN VITRO into the uterine cavity to establish a singleton pregnancy.
Inability to reproduce after a specified period of unprotected intercourse. Reproductive sterility is permanent infertility.
The transfer of mammalian embryos from an in vivo or in vitro environment to a suitable host to improve pregnancy or gestational outcome in human or animal. In human fertility treatment programs, preimplantation embryos ranging from the 4-cell stage to the blastocyst stage are transferred to the uterine cavity between 3-5 days after FERTILIZATION IN VITRO.
The inability of the male to effect FERTILIZATION of an OVUM after a specified period of unprotected intercourse. Male sterility is permanent infertility.
