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 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...
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 ...
The aim of this study is to demonstrate the efficacy of a single embryo transfer at blastocyst stage (Day 5) after co-culture on Autologous Endometrial Cell Culture (AECC) versus transfer ...
Effects of Liuwei Dihuang Granule () on the outcomes of In Vitro fertilization pre-embryo transfer in infertility women with kidney-yin deficiency syndrome and the proteome expressions in the follicular fluid.
To observe the effects of Liuwei Dihuang Granule (, LDG) for tonifying Kidney (Shen) on the outcomes of in vitro fertilization pre-embryo transfer (IVF-ET) of infertility women with Kidneyyin deficien...
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 cl...
Whether hepatitis B virus (HBV) infection impairs human infertility is unclear. The present retrospective case-controlled study investigated the impact of HBV on sperm parameters, ovarian stimulation,...
This prospective randomized study reports the effect of hyaluronan-enriched embryo transfer media on the outcome of in vitro fertilization and embryo transfer (IVF-ET) treatments.
The use of GnRH agonist downregulation in artificial endometrium priming cycles for cryopreserved embryo transfer was retrospectively investigated to establish whether higher live birth rates resulted...
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.
