Background: Repeated Implantation Failure (RIF) is one of the most intricate obstacles in assisted reproduction. The cytokine and chemokine composition of uterine cavity seem to play important roles in the implantation process. Objective: To compare the cytokine profile in the endometrium of normal fertile women and those with repeated implantation failure. Methods: After enzymatic digestion of...

Patients with repeated implantation failures or poor embryo quality may benefit from embryo culture using the co-culture technique; growth factors secreted by co-culture cells may act as survival factors. Autologous endometrial co-culture has been suggested as a safe alternative to animal cells for co-culture of human embryos. However, the technique is fairly labour intensive and its effectiven...

the success rate of several advanced basic and clinical techniques in the field of mammalian biotechnology, including cloning, pre-implantation genetic diagnosis, and assisted reproductive techniques (art) depends mainly on the success rate of pregnancy following in vitro fertilization-embryo transfer (ivfet). the techniques used in art have advanced considerably since the first in vitro fertil...

Cochlear implantation is a method used for the treatment of patients with profound hearing loss. This procedure may the accompanied by some major or minor complications. We evaluated the surgical complications of cochlear implantation in Fars province (south of Iran). A total of 150 patients with cochlear implantation were enrolled in the present study. Most of the patients were pre-lingual chi...

Background: To explore the predictive value of endometrial receptivity and pregnancy outcomes using pipelle biopsy examination during luteal phase menstruation cycle in infertile women. We also compare importance this factor with other potential causes infertility. Methods: This retrospective study included 279 women repeated implantation failures. All patients were examined treated at Interson...

Embryo implantation is a key factor limiting the effectiveness of assisted reproductive technologies, and depends on quality blastocyst susceptibility endometrium. Various methods treatment aimed at improving receptivity uterine mucosa, including endometrial scratching, have been proposed. At same time, main mechanisms underlying this intervention remain unclear. Moreover, optimal duration expo...
