early fetal gender determination using real-time pcr analysis of cell-free fetal dna during 6th-10th weeks of gestation.
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...

The genital region was examined in a midsagittal plane and the fetal gender was assigned as male if the angle o...
متن کاملDetermination of Fetal Gender by Transrectal Ultrasound Examination: Field’s Experience
Fetal determination has been conducted for almost 20 yr. In 1989, Curran and Ginther first identified fetal gender by evaluating the location of the genital tubercle in the male and female fetus using transrectal examination between 54 and 84 days of gestation. More recently, others 4 have described fetal-gender determination in midand late pregnancy using a transabdominal technique. Knowing fe...
متن کاملalgorithm-based fetal gender determination using x and y mini-short tandem repeats at early gestational ages
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...
