Background; Around 15-20% of pregnancies end in miscarriage. The yolk sac initially forms at around 5 weeks gestation and may be viewed via ultrasonography. Both the fetal heart rate can utilized as predictors first trimester result, Aim objectives; to determine relationship between early abortion each ultrasound characteristics measured during (gestational size, fetus activity). Subjects metho...

Background: RIF is the most common cause of unsuccessful pregnancy after IVF. Among the various causes of RIF, the role of maternal genetic factors is of great significance. PAI-1 polymorphism is one of the notable polymorphisms in this field. In this study, the relationship between this polymorphism and the recurrent spontaneous abortions and infertility in different populations has been inves...

Successful embryo implantation is a process which requires both a synchronous development and interaction between hatched blastocyst and endometrium. The process of implantation as a scheme is presented in Pic. 1, where the diagram shows a preimplantation stage of embryo and some important factors thought to be necessary for uterine receptivity: COX-2 (cyclooxygenase-2), EGF (epidermal growth f...

Introduction: The Parikh’s formula is a calculation method that considers menstrual cycle duration in women who have an unusual interval of menstruation cycle. Since the accurate estimation of gestational age affects pregnancy outcomes, the present study aimed to compare the first trimester ultrasound and Parikh’s formula in determining the Expected Date of Delivery (EDD). Mate...

background: singleton pregnancy with a live birth beyond 37 weeks of gestation is the ultimate goal of any assisted reproductive technology. however, singletons conceived after art are found to have a poor perinatal outcome in comparison to naturally conceived singletons. it was hypothesized that the outcome of singleton conceived after transfer of two or more embryos may be dependent on the sh...

Ectopic pregnancy occurs in 1–2% of pregnancies and is the leading cause of maternal mortality in the first trimester; accounting for up to 15% first trimester deaths. There is a worldwide consensus regarding the use of transvaginal ultrasound (TVS) and (serial) quantitative serum human chorionic gonadotrophin (hCG) levels in the diagnosis of ectopic pregnancy. Diagnosis can be straightforward ...

AIMS The present study aimed to determine whether yolk sacs with abnormal sonographic appearance are associated with adverse perinatal outcomes in both early and late gestation. MATERIAL AND METHODS A total of 305 viable singleton pregnancies with gestational age of 6 to 9 weeks were prospectively evaluated with respect to perinatal outcomes and sonographic characteristics of the yolk sacs. ...
