The survival probability of early human conceptions is very low. At least 73% of natural single conceptions have no real chance of surviving six weeks of gestation. After six weeks, survival rates improve rapidly as 90% of the remainder will survive to term. This low fetal loss rate is close to the low rates of 1% - 2.9% for different methods of artificial reproduction. From 16 weeks the rate of loss reduces further, to around 1%.

Introduction: The ‘sterile womb paradigm’ is currently under debate and the advent of next generation 16S rRNA gene sequencing is driving the characterization of microbes associated with the amniotic cavity during pregnancy. Objective: To characterize the bacterial diversity in placentas from preterm and term births using next generation 16S rRNA gene sequencing in association with adverse pregnancy outcomes and histopathology studies. 

Purpose: Doppler flow parameters of fetal umbilical artery (UA) and middle cerebral artery (MCA) have been widely used for fetal growth restriction (FGR), but their diagnostic efficacy remains contentious. The purpose of this study is to clarify the superiority of cerebroplacental ratio (CPR) and umbilicocerebral ratio (UCR) in terms of their correlation and predictive accuracy in diagnosing FGR.

Non-puerperal uterine inversion (NPUI) is an extremely rare cause of acute urinary retention in women of reproductive age. The delay in diagnosing this rare clinical entity presenting with acute urinary retention further complicates the management. The condition's rarity makes it difficult to carry out a study on its prevalence. Hence, most of the evidence comes from case reports or case series.

A 30-year-old woman, in her fourth pregnancy ,at 39+1 weeks gestational age ,experienced a precipitous vaginal delivery. Following delivery, the placenta remained attached and did not spontaneously separate after 20 minutes.
