Background: Vitrification and warming of blastocysts is an established procedure for the preservation of embryos during IVF. Vitrification is so successful that it allows for elective single embryo transfer (eSET) to be performed routinely, since the frozen embryos will be available with high implantation potential if the fresh embryo fails. Comprehensive chromosome screening (CCS) is also a pr...

embryo transfer (et) in holstein dairy cattle became an important commercial enterprise after the introduction of non-surgical recovery technique. embryo transfer could increase the reproductive rate of genetically superior cows. the objectives of the present study were to evaluate the use of et in iranian holstein dairy cattle to increase selection intensity on the dam side, economically; esti...

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...
