background: the latest studies reported that local endometrial injury is a useful method to improve the success of ivf-icsi outcome. objective: to assess whether local endometrial injury occurred by pipelle in the spontaneous cycle could improve implantation rate, cleavage rate, and pregnancy outcome in the subsequent ivf-icsi cycle in patients who had recurrent ivf failure. materials and metho...

BACKGROUND The role of embryo transfer as regards the success of IVF/ICSI treatments is recognized but has not been comprehensively evaluated. In order to determine its importance, the degree of difficulty of 4807 embryo transfers after IVF/ICSI was analysed retrospectively. METHODS Logistic regression analysis identified the age of the subject, type of treatment (IVF versus ICSI), number of ...

Background: The assisted reproductive techniques (ARTs) such as in vitro fertilization, embryo transfer and cryopreservation of gametes have considerably contributed to the development of biomedical sciences in addition to improved breeding in domestic animals and infertility treatment in humans. However, ARTs used in canine species have strictly limited utility when compared with other mammali...

Various assisted reproductive techniques have been developed and refined to obtain a large number of offspring from genetically superior animals or obtain offspring from infertile (or subfertile) animals. The embryo transfer is one assisted reproductive technique developed well, aimed at increased productivity of selected females, disease control, importation and exportation of livestock, rapid...

BACKGROUND We aimed to examine the efficacy of using an embryo transfer medium enriched with hyaluronan (HA) to improve implantation in a selected group of patients aged <43 years with repeated (>4) implantation failures after IVF-embryo transfer. METHODS About 101 patients, meeting our selection criteria, were randomly allocated to undergo embryo transfer either using our routine embryo tran...

The main factors affecting pregnancy and implantation rates are uterine receptivity, embryo quality, and transfer efficiency. Embryo transfer (ET) is the last step of critically important procedure of in vitro fertilization (IVF) and probably the least successful step in Assisted Reproductive Technology (ART) treatment cascade; though simple in most of the cases, it may pose to be the most diff...

BACKGROUND Polycystic ovary syndrome (PCOS) patients are at increased risk of pregnancy complications, which may impair pregnancy outcome. Transfer of fresh embryos after superovulation may lead to abnormal implantation and placentation and further increase risk for pregnancy loss and complications. Some preliminary data suggest that elective embryo cryopreservation followed by frozen-thawed em...

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...
