Background A major hurdle to improved in vitro fertilization (IVF) success rate is defective endometrial receptivity and implantation. Various techniques have been advocated to increase implantation while reducing side effects. Currently, embryo transfer (ET) is performed blindly without direct visualization. As such, we sought to develop a technique utilizing a flexible minihysteroscope with a...

background hearing capability plays a principal role on human's communication. noise-induced hearing loss (nihl) caused by exposure to high noise levels is a serious socio-economic problem in modern societies. nihl can either be reversible, resulting in a temporary threshold shifts (tts) or irreversible, resulting in a permanent threshold shifts (pts). pts is often confirmed in the time span of...

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: the luteal phase defect is a common event following the ovarian stimulation. the aim of the present study was to evaluate the use of human chorionic gonadotropine (hcg) and progesterone hormones to improve the luteal phase defect. materials and methods: 60 mice were superovulated routinely with human menopausal gonadotropin (hmg) (7.5u) and hcg (10u). the mice were mated and divided...

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...

introduction: in recent years, music has been employed in many intervention and rehabilitation program to enhance cognitive abilities in patients. numerous researches show that music therapy can help improving language skills in patients including hearing impaired. in this study, a new method of music training is introduced based on principles of neuroscience and capabilities of persian languag...

Background: To evaluate the impact of stimulating the endometrium with high-grade blastocyst culture supernatant (SEHB) perfusion before blastocyst transfer (BT) on implantation rate, pregnancy rate, and pregnancy outcome in ICSI cycles Materials and Methods: Ninety-four infertile couples who were referred to the Valiasr department of Imam Hospital complex between January 2010 and March 2011 en...
