introduction: regarding to the recent advances in assisted reproductive techniques (art), twin and multiple pregnancies have increased during past years. objective: this study was performed to compare obstetrics and perinatal outcomes of dichorionic twin pregnancy following art with spontaneous pregnancy. materials and methods: in this cross-sectional study which was performed in ghaem hospital...

Background: The cause of fertilization failure in IVF is most often due to the absence of sperm penetration but the reason why fertilization does not occur when intracytoplasmic sperm injection (ICSI) is applied is not clear. However some intrinsic oocyte problems may also be responsible for fertilization failure. It has been reported that 13% of unfertilized oocytes after IVF show morphologica...

background:   objective: the aim of our study was to assess the effect of storage duration of frozen embryo on art outcome.   materials and methods: in this retrospective study the data of 651 frozen-thawed embryo transfer cycles were assessed over a 36-months period. our patients were categorized according to storage time of freeze. group i: less than 90 days, group ii: between 90-365 days. gr...

background: female age and basal fsh level are independently associated with ivf outcome. they are both related to the same phenomenon, namely ovarian reserve. objective: to evaluate the effective role of serum fsh concentration at the start of treatment cycle on art outcome. materials and methods: a total of 207 women undergoing ivf and icsi cycles were included in this study. basal fsh concen...

Background: To investigate whether endometrial volume on the day of HCG (human chorionic gonadotropin) administration is a predictor of ART (assisted reproductive outcome) outcome Materials and Methods: Two hundred and seven patients in ART cycle were included in this prospective study; In order to evaluate endometrial volume and its relationship to ART outcome. Endometrial volume obtained from...

Background: The establishment of a high quality ART program requires a multi-disciplinary effort, involvement and commitment of all staff members – team work. It is of vital importance that all aspects of the treatments are taken into consideration and that you already from the start use high international standards to initiate a wellorganised ART program that meets the requirements from patien...

Background: Our Background was to evaluate the effect of ovarian endometrioma on ovarian stimulation outcomes in Intra Cytoplasmic Sperm Injection (ICSI). Materials and Methods: In this prospective cohort study, we followed 103 patients underwent ICSI procedures at royan Institute during 10 month. The study group consisted of 46 women who had endometriomawith size more than 1 cm. The control gr...

PCOS is still a problem in gynecology and infertility. Especially in ART the problem of PCOS patients is bigger and more highlighted. These patients are prone to over and under stimulation. Strategies to overcome hyper stimulation are: use of metformin, ovarian drilling, use of minimal stimulation, suppressing LH with use of OCP or GnRh analogues, use of GnRh antagonist in COH. But none of thes...

background: gonadotrophin-releasing hormone (gnrh) agonist is used for controlling ovarian stimulation in assisted reproductive technology (art) cycles which has some benefits. objective: to compare the efficacy of two different formulations of gnrh agonist: short-acting and long-acting, for art protocols. materials and methods: in a prospective randomized study, one hundred women who underwent...

Background The aim of this study was to compare prenatal outcome of intra cytoplasmic sperm injection (ICSI) pregnancies with pregnancies obtained through in vitro fertilization (IVF). MaterialsAndMethods Retrospectively 532 pregnancies of ART cycles were assessed during 1999-2000. The main outcome measured including abortions, ectopic pregnancies, prematurity, low birth weight, cesarean sectio...
