BACKGROUND Environmental and endocrine factors have been implicated in the aetiology of recurrent abortion, with poorly understood roles. Luteal phase insufficiency marked with insufficient progesterone secretion has been reported. OBJECTIVE To define the involvement of progesterone, trace metals, and Vitamin E in pregnant women with history of recurrent spontaneous abortion. METHODS Conven...

CONTEXT Bacterial vaginosis (BV) is related to the increased risk of miscarriage, preterm labor, and postpartum endometritis. AIMS The aim of this study was to evaluate the association between BV and the history of spontaneous abortion and recurrent pregnancy losses. We also examined periods of gestation, including the first and second trimester miscarriages. MATERIALS AND METHODS The study...

An increased frequency of mitoses with centromere separation affecting all chromosomes was found in lymphocyte cultures of couples with recurrent spontaneous abortions. This anomaly was recorded in six individuals out of seventy couples (one hundred and forty individuals) with recurrent miscarriages. The abnormal behaviour of centromeres may predispose the individual to cell division errors, th...

Background Spontaneous abortion has been defined as two or more consecutive miscarriages at 20 weeks pregnancy. Vascular endothelial growth factor (VEGF) plays a main role in fetal and placental angiogenesis which secretes from different cells like endometrium and placenta.The objective of this study was to investigate of association of VEGFA gene polymorphisms and recurrent spontaneous abortio...

We aimed to explore the correlation between unexplained recurrent spontaneous abortion and polymorphisms in the methylene tetrahydrofolate reductase (MTHFR) and methionine synthase reductase (MTRR) genes. A case control study was conducted in 118 patients with unexplained recurrent spontaneous abortion (abortion group) and 174 healthy women (control group). The genetic material was extracted fr...

In the present study, we analyzed the proliferation and apoptosis of trophoblasts and human decidual cells in patients with recurrent spontaneous abortion and the related cellular pathway mechanism. Thirty-four patients with recurrent abortion and 30 healthy pregnant women undergoing planned artificial abortion were selected. The trophoblast and decidual cells were collected by negative pressur...
