Background Effects of GCSF (Granulocyte Colony-stimulating Factor) injection in patients suffering from recurrent pregnancy loss has been studied in some studies and we now know that transvaginal perfusion of G-CSF might be helpful for improvement of implantation rate among patients with thin endometrium and patients under in vitro fertilization /embryo transfer (IVF/ET) or intracytoplasmic spe...

Objective The success rates of assisted reproduction technology (ART) could be developed with the improvement of ovarian stimulation protocols as well as the optimization of final oocyte maturation. The goal of this study was to compare oocyte maturation, fertilization and pregnancy rates among women with concomitant FSH administration at the time of hCG trigger and the hCG trigger alone. Mater...

Objective(s): Progestrone is a prequisite for pre-implantation angiogenesis and induce decidual angiogenesis. It is unknown the effect of progestrone administration on the endometrium of hyperstimulated mice at pre-implantation time. Material and Methods: Adult female NMRI mice were divided in three groups [control group, ovarian stimulated group and progestrone treated mice after ovarian stimu...

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: despite numerous developments in the field of assisted reproduction the implantation rate remains low .recent studies suggested that local injury to endometrium in controlled ovarian hyper stimulation cycle improves implantation rate. studies have attempted to intervene in the development of endometrium. objective: the aim of the present study was the exploration of the possibility ...

background: gnrh agonist and antagonist were developed to control the premature release of lh surge. there is some difference between two protocols. objective: we compared the outcome of frozen-thawed embryo transfer in infertile women who used gnrh agonist or antagonist protocol for previous coh cycle and evaluation of any adverse effect of gnrh antagonist on oocyte and embryo. materials and m...

Background: Apoptosis is a process that plays an important role during early stage of implantation. The aim of this study was to investigate the incidence of apoptosis in mice endometrium after ovarian stimulation at implantation period. Methods: NMRI female mice were divided into two groups: 1) control group, which were rendered pseudopregnant by vaginal stimulation and 2) experimental group, ...

Background: While mammalian embryos can adapt to their environments, their sensitivity overshadows their adaptability in suboptimal in vitro conditions. Therefore, the environment in which the gametes are fertilized or to which the embryo is exposed can greatly affect the quality of the embryo and consequently its implantation potential. Objectives:</stro...
