Optimal Timing For Embryo Transfer For Low Responder Patients

2014-07-23 16:11:16 | BioPortfolio


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.

Embryo Transfer: Direct Versus Afterloading Trial

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.

Comparison of 5 Day Embryo Transfer With 2-3 Day Transfer in Patients With Previous In Vitro Fertilization Failure

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...

Endometrial Curettage Before Embryo Transfer

Studies have shown that endometrial sampling in the month prior to embryo transfer may increase pregnancy rates. We wish to test this hypothesis by performing a hysteroscopy and curettage ...

Medical and Biotech [MESH] Definitions

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.
