Background and purpose - There have been few studies on the effect of THR on pregnancy or delivery, and they have mainly been based on small and regional data. We evaluated the birth rate nationwide in patients of fertile age with THR. Patients and methods - This nationwide population-based cohort study was based on registry data on 5,863 Finnish THR patients who had undergone a THR between 198...

OBJECTIVES Kazakhstan's live-birth definition--that dates from the former Soviet Union (FSU) era--differs from that used by the World Health Organization (WHO). We studied the impacts of both live-birth definitions on the computations of the infant mortality rate (IMR) and maternal and child health (MCH) planning in Zhambyl Oblast, Kazakhstan. METHODS We interviewed caregivers and abstracted ...

Background: Obesity has been associated to negative effects on natural fertility and a worse prognosis when assisted reproduction techniques are performed. Patients attending for fertility treatments are often advised to optimize their weights to improve outcomes. There are doubts about how effective are weight-loss interventions for improving fertility in women who are overweight or obese. Mat...

It is defined as two or more consecutive loss of clinical pregnancies. However, the incidence of RPL is less than 5% in pregnant women but its etiology is diverse and varied and also for more than 50% of cases is not clearly d...

Abstract Study question The purpose of this study is to compare cumulative live birth rate and perinatal outcomes embryos cultured in 20% oxygen 5% oxygen. Summary answer Atmospheric concentration not only affects the quality embryos, but also weight after embryo transfer. What known already Whether culture can effectively improve outcome embryonic pregnancy still controversial. There a lack sc...

To optimize success rates of IVF, selection of the most viable embryo(s) for transfer has always been essential, as embryos that are cryopreserved are thought to have a reduced chance of implanting after thawing. Recent developments challenge this concept. Evidence is accumulating that all embryos can now be cryopreserved and transferred in subsequent cycles without impairing pregnancy rates or...

OBJECTIVE To evaluate the effectiveness of routine ultrasound scanning in pregnancy by a meta-analysis of various outcome measures. DESIGN Meta-analysis of randomised controlled trials evaluating the effect of routine ultrasound scanning on perinatal mortality and morbidity. Live birth rate (that is, live births per pregnancy) is included as a measure of pregnancy outcome in addition to the c...

Possible effects of Chernobyl fallout on outcome of pregnancy in Finland were evaluated in a nationwide follow-up study. The outcomes were the rate of live births and stillbirths, pregnancy loss, and induced abortions by municipality. Exposure was assessed based on nationwide surveys of radiation dose rate from the Chernobyl fallout, from both external and internal exposures. Using these measur...
