nowadays, new advances in the use of cell free fetal dna (cffdna) in maternal plasma of pregnant women has provided the possibility of applying cffdna in prenatal diagnosis as a non-invasive method. in contrary to the risks of invasive methods that affect both mother and fetus, applying cffdna is proven to be highly effective with lower risk. one of the applications of prenatal diagnosis is fet...

background detection of fetal dna in maternal blood has been examined by many research groups for a few years; thereby, scientists have a shorter way to take to approach prenatal diagnosis of abnormal pregnancies. the y chromosome sequences have recently become the most common applicable indices for fetal sex determination. objectives we conducted an algorithmic x and y mini-short tandem repeat...

workers of operating rooms in hospitals are chronically in exposure to rather higher dose of chemicals, e.g. halothane and nitrous oxide, than general population. concern that exposure to waste anesthetic gases may cause mutagenic, carcinogenic, or teratogenic changes has provided the impetus for many recent studies. the goal of present work was to determine incidence of the fetal deaths and se...

Background and Aims: New advances in the use of cell-free fetal DNA (cffDNA) in maternal plasma of pregnant women has provided the possibility of applying cffDNA in prenatal diagnosis as a non-invasive method. One of the applications of prenatal diagnosis is fetal gender determination. Early prenatal determination of fetal sex is required for pregnant women at risk of X-linked and some endocrin...

background: free fetal dna (ffd) in maternal plasma/serum has increasingly become the source of fetal material for diagnostic purposes in recent years. this source of fetal material can be used for sex determination. rh typing paternally inherited sequences and compound heterozygosity. reports on the lack of consistent pcr amplification of y-chromosome sequences of ffd in maternal plasma/serum ...

the first step in the prenatal diagnosis of x-linked genetic disorders is determining fetus gender. current invasive methods to obtain the dna source of the fetus instead of its miscarriage risk, has harmful stress for high risk pregnancies. cell free fetal dna (cffdna) circulating in the maternal blood, has now become a useful source of noninvasive prenatal diagnosis. considering limitation of...

The association of fetal sex with pregnancy induced hypertension and pre-eclampsia, the interaction between sex and risk factors for fetal growth restriction, and the increased likelihood of second stage arrest with male sex have all been studied. However, a Medline search (1966 to August 2002) using the search terms fetal gender, fetal sex, labour, delivery, and childbirth found no studies on ...

Objectives. The aim of this study was to determine whether prospective parents, primarily referred for prenatal diagnosis to exclude Down syndrome, prefer to know the fetal sex as part of invasive testing. Methods. In this prospective study 400 pregnant women undergoing amniocentesis were invited to answer a questionnaire, including information about demographic factors, current pregnancy, and ...
