Embryo Transfer: Direct Versus Afterloading Trial
Summary
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.

Medical and Biotech [MESH] Definitions
Single Embryo Transfer
The techniques used to select and/or place only one embryo from FERTILIZATION IN VITRO into the uterine cavity to establish a singleton pregnancy.
Embryo Transfer
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.
Energy Transfer
The transfer of energy of a given form among different scales of motion. (From McGraw-Hill Dictionary of Scientific and Technical Terms, 6th ed). It includes the transfer of kinetic energy and the transfer of chemical energy. The transfer of chemical energy from one molecule to another depends on proximity of molecules so it is often used as in techniques to measure distance such as the use of FORSTER RESONANCE ENERGY TRANSFER.
Reproductive Medicine
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)
Embryo Disposition
Process for deciding utilization or disposal of an embryo that is fertilized but not immediately transplanted and resulting course of action.

Optimal Timing For Embryo Transfer For Low Responder Patients
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...
Pre-Implantation Genetic Screening in Women Under the Age of 36 Years With Single Embryo Transfer
BACKGROUND: Single-embryo transfer is a well-accepted strategy to avoid multiple pregnancies in an assisted reproductive technology programme. The selection of the embryo with the highest...
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...
The objective of this study is to evaluate the efficacy of embryo transfer procedure guided by transvaginal ultrasound versus abdominal ultrasound in recipients of oocytes as well as the a...
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...

Day 2 versus day 3 embryo transfer in poor responders: a prospective randomized trial.
Day 2 embryo transfer has been suggested as a method to improve pregnancy rates in poor responders compared with day 3 transfer. Our prospective randomized controlled trial does not show a difference...
PURPOSE: A laser is commonly used to remove a blastomere from an embryo for genetic testing. The laser uses intense heat which could possibly disrupt embryo development. It is the goal of this study t...
Effects of Repeated Embryo Collection on Embryo Recovery Rate in Fertile Mares.

Biological predictive criteria for clinical pregnancy after elective single embryo transfer.
In this prospective observational study, the onset of a clinical pregnancy after elective single embryo transfer (eSET) was significantly associated with: 1) the woman's age as well as the number of g...
Aim: To confirm whether women who choose to have one fresh embryo transferred and one frozen-and-thawed embryo when needed can dramatically reduce the possibility of a multifetal pregnancy while givin...
