background: the selection of blastocyst warmed for transfer is based on pre-freeze morphology in vitrified-warmed single blastocyst transfer cycles. but, it is controversial which parameter of blastocyst morphology most closely related to the clinical outcomes. objective: to estimate the effect of blastocoele expansion, trophectoderm (te) morphology grade, and inner cell mass (icm) morphology g...

background: premature luteinization during in vitro fertilization was commonly happened before the introduction of gnrh analogues. high level of unwanted progesterone is associated with adverse pregnancy outcome and is thought to be induced by inappropriate lh elevation.objective: to evaluate the progesterone level on the day of human chorionic gonadotropin (hcg) triggering in gnrh agonist and ...

Pregnancy and childbearing rates for teenagers remain high in the United States despite well-documented associated adverse health, social, and economic consequences for many of these teenagers and their children. In 1990, approximately 835,000 (10%) teenagers aged 15-19 years became pregnant and either gave birth or had an abortion (CDC, unpublished data, 1995); an estimated 95% of such pregnan...

background: the purpose of the study was to evaluate the role of progesterone/ estradiol (p4/e2) ratio as a predictive tool for clinical pregnancy in art cycles with a premature progesterone rise of >1.5 ng/ml on the day of human chorionic gonadotropin (hcg) trigger. methods: retrospective analysis was done on 569 fresh embryo transfer cycles from january 2011 to december 2012 at the infertilit...

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. 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 clinical trial, ...

background: so far, many studies investigated factors that affect pregnancy rates after intrauterine insemination (iui). various investigators have not agreed on the nature and ranking of these criteria. objective: the aim of this study was to assess the predictive factors for pregnancy rate after controlled ovarian hyperstimulation (coh)/ iui. materials and methods: retrospective study of all ...

premature rupture of membrane (prom) is one of the complications of pregnancy which is blamed for increasing the rate of cesarean. therefore, we studied pregnant women who were admitted in shariati hospital during march 1996 and march 2000, to determine the rate of cesarean delivery in cases with prom after 36th week of pregnancy (term prom). in a retrospective study, we included pregnant women...

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...

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...
