background: preterm labor (ptl) is one of the most important causes in neonatal mortality and morbidity. late preterm labor (34-36w) includes 75% of such birth. assisted reproductive technology (art) pregnant women are at increased risk of ptl. objective: the study has been undertaken to determine whether beginning and continuing 17-α hydroxy progesterone caproate can reduce risk of ptl or chan...

Background: HLA-G, as a tolerogenic molecule, expressed in cytotrophoblast cells and playing an important role in the suppression of the immune response in maternal decidua. Today Interaction of the extracellular domains of HLA-G protein with cell receptors of immune system, including CD8, LILRB1, LILRB2 and killer cell immunoglobulin-like receptor KIR2DL4, was well known. Materials and Methods...

  Background: Improvement of assisted reproductive technique (ART) results in higher pregnancy rates from positive Beta HCG to take home baby statistics. Despite developments in culture media allowing blastocyst stage transfer, some centers apply second, third and sometimes fourth day post injection for embryo transfer. This study aimed to compare their reproductive outcomes.   Methods : This p...

Cross-border reproductive care (CBRC) is a growing worldwide phenomenon, raising questions about why assisted reproductive technology (ART) patients travel abroad, what harms and benefits may result, and what duties health care providers may have in advising and treating patients who travel for reproductive services. Cross-border care offers benefits and poses harms to ART stakeholders, includi...

Background: Vitamin D, a steroid hormone, has critical roles in human health. The available data thus identify vitamin D as an important substance in processes involved in reproductive success and thereby suggest pathophysiological mechanisms for reproductive compromise in the setting of vitamin D deficiency. Realizing the prevalence of vitamin D insufficiency in our country, we hypothesized th...

background: knowledge of infertile couples about assisted reproductive technology is a fundamental parameter to optimize the infertility treatment and conduct it cooperatively. objective: to evaluate knowledge and attitude of infertile couples about assisted reproductive technology we designed a descriptive cross-sectional study. materials and methods: 400 infertile patients were investigated b...

background: assisted reproductive technologies (art) are known as a treatment for infertility in which oocyte undergoes manipulation outside body. the aim of this study was to study the evaluation of birth defects in infants conceived through assisted reproductive technologies (art) and compare them with naturally-conceived infants. materials and methods: in this retrospective study, four hundr...

Objective To verify the hypothesis that the incidence of chromosomal abnormalities increases in babies conceived by different assisted reproduction procedures. The availability of the umbilical cord blood encouraged us to study this hypothesis via this method. MaterialsAndMethods This is a descriptive study, umbilical cord blood samples of assisted reproductive technology (ART) children were an...

The last two decades have seen an increase in the number of women diagnosed with infertility. The consequent growth in the use of assisted reproductive technologies (ART) calls for the determination of its long-term effects, including the risk of cancer. Many studies have attempted to answer this question, albeit with contradictory results. This review aimed to assess whether assisted reproduct...
