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...
to evaluate the value of using transvaginal ultrasound guided embryo transfer in obese patients undergoing in vitro fertilization.
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...
Elective frozen-embryo transfer has been shown to result in a higher live-birth rate than fresh-embryo transfer among anovulatory women with the polycystic ovary syndrome. It is uncertain whether froz...
Controlled ovarian stimulation in assisted reproduction technology (ART) may alters endometrial receptivity by an advancement of endometrial development. Recently, technical improvements in vitrificat...
Among women who are undergoing in vitro fertilization (IVF), the transfer of frozen embryos has been shown to result in a higher rate of live birth than the transfer of fresh embryos in those with inf...
To identify the impact of embryo transfer time (total seconds from the loading of the transfer catheter to the expulsion of the embryo(s) into the uterine cavity) on clinical pregnancy (CPR), implanta...
Many adjuvant therapies are employed during IVF treatment in an attempt to improve outcomes. The objective of our study was to evaluate the impact of thirteen adjuvants (Intralipid, steroids, melatoni...
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 inability of the male to effect FERTILIZATION of an OVUM after a specified period of unprotected intercourse. Male 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.
