conclusions it was observed that the success and survival rate of maxillary molar immediate implant was relatively high and similar to those of conventional delayed implants. results immediate implants were most frequently used for incisor and premolar sites and there is very little data available on immediate implantation in the molar area. in this research, we reviewed all the existing papers...

background: pregnancy rate with ivf cycle is almost 22%. many investigations perform to increase this rate in ivf. various factors affect the result of ivf cycles. one of these factors could be uterine contractions that expel transferred embryo. ritodrine is a beta mimetic agent that can block and decrease uterine contractions. objective: the objective of this study was to determine ritodrine e...

hydrosalpins (dilatation of fallpian tube that can be seen by hysterosalpingogeraphy. laparoscocpy, and in severe cases by sonography) is one of the probable confounding factors of assited – reproduction therapy (art) outcomes. this cohort study is conducted to determine the effects of hydrosalpins on ivf-et outcomes. for this, of the total number of patients who had approached the infertility ...

background: release of vascular endothelial growth factor (vegf) by ovaries in response to hcg administration is one of the main mechanisms of ovarian hyper stimulation syndrome. since dopamine/dopamine receptor2 (dp-r2) pathway activity -mediated by vegf/ vascular endothelial growth factor receptor 2 (vegfr-2) signaling-, is associated with angiogenic events, dopamine agonists were used for th...

background: repeated implantation failure (rif) is defined as pregnancy failure after two to six times with at least ten high grade embryo transfer to uterus. a variety of causes have been anticipated for rif, including anatomical, autoimmune, genetics, endocrine and thrombotic anomalies. factors responsible for rif have important implication regarding treatment however in many couples a perfec...

background: implantation failure is one of the most important factors limiting success in ivf treatment. the majority of trials have demonstrated favorable effect of endometrial injury on implantation success rate especially in women with recurrent implantation failure, while some studies failed to detect any benefit. objective: the purpose of our trial was to explore whether endometrial injury...

objective: repeated implantation failure (rif) is a condition in which the embryos implantation decreases in the endometrium. so, our aim was to evaluate the effect of local endometrial injury on embryo transfer results. materials and methods: in this simple randomized clinical trial (rct), a total of 120 patients were selected. the participants were less than 40 years old, and they are in thei...

background: implantation remains a limiting step in ivf/icsi. endometrial injury isa promising procedure aiming at improving the implantation and pregnancy rates after ivf/icsi. objective: the aim of this study was to evaluate the effect of endometrial injury induced in precedingcycle on ivf/icsi outcome. materials and methods: four hundred patients undergoing their first ivf/icsi cycle in two ...
