It is possible to determine the gender of your baby in advance of his or her birth using the mother’s urine as a test sample to conduct a gender prediction test. Yes, you can get the same information from an ultrasound scan, but mistakes can be made with ultrasound – they are not unusual in fact, moreover, ultrasounds are not reliable in the early months of pregnancy and are not recommended by the FDA to determine baby gender.

There is no general consensus as to the accuracy of ultrasound, and of several tests carried out, it seems to be somewhere between 75% and 90%. There also seems to be a high inconclusive rate, where the gender of the baby cannot be determined. You also have to wait a fairly long time: 16-24 weeks is reported, although not too long if all you want is time to decorate, decide a name or buy the appropriate clothes.

However, can you tolerate such a high margin of error or indecision? By testing the urine of the mother it is possible to determine the gender of your baby to over 99% accuracy at 9 weeks after the end of your last period. This is achieved by means of a non-invasive DNA gender prediction test carried out in an accredited laboratory that is also equipped to carry out maternal and paternal DNA testing to high degrees of accuracy.

Steer clear of certain gender prediction tests, especially old wives’s tales but also the home tests for hormones that are carried out on the mother’s urine as these have a very low success rate – as low as 45% in many cases though this increases at the 12th week.

No non-invasive test, however, is as accurate or as fast as the KnowtheGender test at over a 99% accuracy rate from week 9 of pregnancy.

The Science Behind the Gender Prediction Test

What is special about KnowtheGender, and why is it so accurate to determine the gender of your baby using this method with just a sample of the mother’s urine? The answer to this comes from the way the test sample is prepared, but first a quick summary of the science behind the test.

The amniotic fluid in the womb contains DNA strands from the baby that increase with time. These are absorbed along with other fluids from the womb into the placenta where they are then transferred to the mother’s blood bloodstream. The DNA strands are filtered out by the kidneys, and transferred to the urine. Much of the DNA is destroyed here, leaving only a few identifiable strands.

Males and females have 23 pairs of chromosomes in their DNA, of which one pair consists of the sex chromosomes: X or Y. Females have two X chromosomes making up the pair, and a male an X and a Y. The female egg and male sperm are known as gametes, and contain only one half of the pair: an X chromosome in the egg, with the sperm containing either an X or a Y chromosome. The chance of an X or a Y is 50% – nature’s way of maintaining equality of the sexes (though in relative number only!).

If the male gamete (sperm) containing the X chromosome combines with the X gamete (ovum) of the female, the zygote formed will be female. If the sperm contains a Y chromosome, the zygote will be male. The zygote eventually develops into your child.

The mother’s urine can be used to determine the gender of your baby by detecting whether or not it contains that Y chromosome indicating a boy. If it is not present, then your baby is a girl.

Why So Accurate?

So why is this gender prediction test so accurate? Simple: even though the DNA strands obtained from the womb are mostly broken down, there are enough for the laboratory to use. Our scientists use a technique known as polymerase chain reaction (PCR). DNA polymerase is an enzyme that copies DNA – using it, our scientists can create many hundreds of copies of the DNA strands and use them to analyze for the Y chromosome.

Without using PCR, it would not be possible to carry out this test as early as 9 weeks. Some try to do this at 7 weeks, but their results are very inaccurate, and there is no fetus DNA detectable in urine below 7 weeks. By using the PCR technique, the laboratory achieves an accuracy of more than 99%.

This baby gender test is more accurate than any other non-invasive technique, and can be carried out much earlier in your term than any other method, including ultrasound or hormone testing (both also less accurate).

If you want to know how to determine the gender of your baby as soon as possible and as accurately as possible by using the urine gender prediction test, then this is it. We will send you our sampling kit with all you need to collect the sample and return it to us. Your certificated results will be available in 7-10 working days, or sooner if you need it.
