Predictions of Your Baby's Sex

Scientific prediction of sex of the fetus now has several ways:
(1) 3-4 months of gestation, the pregnant uterus from the lower abdomen would draw a small amount of amniotic amniotic fluid, amniotic fluid on the high-speed centrifuge to centrifuge, retaining cell mass, and after fixation, drying and dyeing and other steps, and then observed under the microscope on the nucleus of the x and Y chromosome, when the x chromosome in 10% or more, you can forecast for the female fetus, when the Y chromosome of 20% to 25% a diagnosis of male fetuses.
(2) about 70 days of pregnancy, the uterus or cervix from the vaginal secretions take a little, made smear, microscopic examination of fetal cells with the "sex chromosomes", and to determine the fetus is male or female.
(3) measured a drop of blood from pregnant women, sex of the fetus, this method has recently started to use at home and abroad, and achieved satisfactory results. In the women's earlobe or finger taken a drop of blood on the glass slide, pushed into the blood films, stained with special methods, to be dried on the optical microscope counting 200-1000 neutral leaf of the white blood cells, records found that the nuclei of neutral leaf white "drumstick body" number. Neutral in the leaf count of 200 white blood cells after 3 to 10 months if it is found "drumstick body" when compared with male fetuses, found that 0 to 2 for the female fetuses. Neutral in the 1000 count of white blood cells when the leaf, if it is found in more than 12 "drumstick body" to predict fetal sex of the fetus is male, found O-lO months to female fetuses.
According to reports, counting 200 white blood cells leaves the neutral point accuracy was 92%, while the exact count of 1000 was 98%. Prediction of fetal sex with other methods, this method is simple, accurate and a half months from the beginning of pregnancy until delivery can be carried out before, if a higher accuracy rate of repeat checks.
