Implantation support medium transfer (ISME-T) is referred as cultivation and transfer of embryos using advanced enriched medium that all nutrients and energy sources needed for an optimal embryo development. They may serve as cultivation as well as transferring medium. Enriched cultivation medium reduces the embryo stress through in vitro fertilization (IVF) process by providing a more physiolo...

BACKGROUND The purpose of the study was to compare clinical pregnancy and delivery rates with fresh and frozen embryo transfer in patients admitted to Shiraz- Human Assisted Reproductive Center with ovarian hyperstimulation syndrome (OHSS). METHODS OHSS patients randomly divided in two groups, group A (n=50) with fresh embryo transfer and group B (n=50) with frozen embryo transfer. We used vi...

In vivo fertilisation techniques such as intraoviductal oocyte transfer have been considered as alternatives to bypass the inadequacy of conventional in vitro fertilisation in rabbit. There is only one study in the literature, published in 1989, that reports live offspring from cryopreserved rabbit oocytes. The aim of the present study was to establish the in vivo fertilisation procedure to gen...

Background: The role of embryo transfer (ET) in the success of in vitro fertilization/intra cytoplasmic sperm injection treatment is not well understood. In the present study we classified ET technique as difficult and easy types according to certain strict criteria, and compared the pregnancy outcome of

At present, embryo transfer can be performed successfully in most of the mammalian species. There is a high degree of similarity concerning the reproductive functions in these species. In all species there are strong scientific and also practical reasons for the applications of embryo transfer and the associated techniques which will gain more importance in the future.

The aim of the study was to evaluate if the elective single embryo transfer (eSET) strategy could maintain the delivery rates, with at least one live born child, and at the same time decrease the rate of multiple births. A costeffectiveness analysis was also performed between the elective single embryo transfer (SET) (1+1) and double embryo transfer (DET)(2+0) strategies. Another aim was to inv...

Thanks to assisted reproduction technology (ART) most couples with infertility can be helped today. Since the beginning of ART, however, two major problems have existed. In the first years of IVF more than one embryo was transferred in order to reach acceptable pregnancy rates, but this entails a risk of multiple pregnancy with all its morbidity and mortality due to premature birth. Also, studi...

the latest micromanipulative technique, intracytoplasmic sperm injection (icsi), has been very successful in cases of severe male factor infertility. the main objective of this study is to report the results of our first experience with icsi in cases of male factor infertility, as well as patients who had failed their previous cycles with conventional in vitro fertilization (ivf). normal fertil...

Purpose The aim of the present prospective study was to investigate the efficacy of hyaluronan (HA) using two different concentrations as embryo transfer media for in vitro fertilization embryo transfer cycles. Methods A total of 169 cycles undergoing fresh embryo transfer on day 2 or 3, 561 cycles undergoing frozen-thawed embryo transfer on day 2 or 3, and 484 cycles of frozen-thawed blastoc...

N umerous publications have investigated the practice of elective single-embryo transfer (eSET) (1–27). Single-embryo transfer after in vitro fertilization (IVF) has been advocated as the only effective means to avoid multiple pregnancy in IVF cycles (28). Elective SET is defined as the transfer of a single embryo at either the cleavage or blastocyst stage of embryo development that is selected...
