UNLABELLED OBJECTIVES This study sought to evaluate the outcome of fresh and vitrified-warmed cleavage-stage and blastocyst-stage embryo transfers in patients undergoing ART treatment within an ethnic Chinese population. STUDY DESIGN We compared the clinical results of embryo transfer on the 3rd (cleavage stage) or 5th (blastocyst stage) day after oocyte retrieval, including clinical pregn...

Objective The success rates of assisted reproduction technology (ART) could be developed with the improvement of ovarian stimulation protocols as well as the optimization of final oocyte maturation. The goal of this study was to compare oocyte maturation, fertilization and pregnancy rates among women with concomitant FSH administration at the time of hCG trigger and the hCG trigger alone. Mater...

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...

Background:Expression of granulocyte colony stimulating factor (G-CSF) and its receptors in embryo and endometrium implicates the involvement of this glycoprotein on implantation process. In the present study, we aimed to evaluate the impact of routine use of subcutaneous administration of G-CSF on pregnancy outcomes in intracytoplasmic sperm injection (ICSI) patients. <strong...

Background Implantation failure is the most important cause of recurrent in vitro fertilization/intra cytoplasmic sperm injection (IVF/ICSI) failure. Several reports suggest that intercourse during the peritransfer period might improve pregnancy rates. This study is designed to determine whether intercourse during the peritransfer period will improve pregnancy and implantation rates in patients...

The differential diagnosis of acute abdominal pain in pregnancy is broad and can be complicated by atypical manifestations that are due to the anatomic distortions and physiologic changes of pregnancy. Due to the lack of clinical understanding, angular pregnancy does not appear to be recognized as a clinical entity and many cases are likely to go undiagnosed. This is a case report of a 34-year-...

Aim: To evaluate the clinical significance of factors predisposing to severe form SARS-CoV-2 virus infection during pregnancy. Material and methods study. 240 pregnant women with signs acute respiratory disease were examined. All subjected general clinical, obstetrical, clinical-laboratory examination (general analysis blood, urine, biochemical blood tests, coagulogram, PCR diagnostic test veri...

BACKGROUND There exist contradictive views on whether the vitamin D has association with clinical outcome of in vitro fertilization (IVF) and/or intracytoplasmic sperm injection (ICSI). The present meta-analysis aim to establish whether vitamin D was associated with clinical outcomes of IVF/ICSI. METHODS MEDLINE, Google Scholar and the Cochrane Library from database inception to March 2017 we...

background: despite major advances in assisted reproductive techniques, the implantation rates remain relatively low. some studies have demonstrated that intrauterine infusion of granulocyte colony stimulating factor (g-csf) improves implantation in infertile women. objective: to assess the g-csf effects on ivf outcomes in women with normal endometrial thickness. materials and methods : in this...
