background: c-reactive protein (crp) can be increased after hormonal stimulations. the changes of crp might affect the success of in-vitro fertilization (ivf). objective: the aim of this study was to determine the possible relationship between the serum crp level and outcome of controlled ovarian stimulation, and pregnancy rate in patients undergoing ivf or intra cytoplasmic sperm injection (ic...

background: general concern is that the pregnancy rate is higher with gnrh-agonist as a protocol of pituitary suppression. gnrh-antagonist protocol provides a shorter period of administration and an easy flexible protocol. objective: in this study, the outcomes of gnrh agonist and antagonist in icsi cycles are compared in normo responder patients. materials and methods: in this randomized clini...

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 ...

the main factors affecting pregnancy and implantation rates are uterine receptivity, embryo quality, and transfer efficiency. embryo transfer (et) is the last step of critically important procedure of in vitro fertilization (ivf) and probably the least successful step in assisted reproductive technology (art) treatment cascade; though simple in most of the cases, it may pose to be the most diff...

background: embryo transfer (et) has traditionally been performed two days after oocyte retrieval. delaying transfer from day two to day three or four would allow for further development of the embryo might therefore optimize the selection of viable and best quality embryos for transfer and may be closer to the physiological time of the entry into the uterus than transfer on day two and might h...

introduction: prevalence of infertility in general population is around 15-10 percent. intra- uterine insemination (iui) is one method for treatment of infertility. success rate of this method is affected by different factors. past studies have shown that induction of ovulation and iui has increased significantly the chance of pregnancy in the infertile couple, especially male factor infertilit...

Background: The objective of this study is to evaluate the progesterone level (P Level) on the day of HCG triggering in GnRh agonist and antagonist protocols, and its correlation with clinical pregnancy rate and miscarriage rate. Premature luteinization during in vitro fertilization (IVF) was commonly happened before the introduction of GnRh analogues. High level of unwanted progesterone that i...

background: embryo transfer has received little clinical attention and has been the most inefficient step in in-vitro fertilization (ivf). recent reports have suggested that an awareness of the position and length of the uterus during embryo transfer might be helpful in improving pregnancy rate. objectives: the main objective of the present study was to determine the relation between the length...
