What Determines Baby Gender

Boys have 23 pairs of XY chromosome and females have 23 pairs of XX chromosomes. We have a total of 46 chromosomes. There are cases where people may have less chromosomes or even extra chromosomes – this condition is known as aneuploidy (for example Down syndrome people have 1 extra chromosome and there is another condition knows the Triple X where sufferers have an extra X chromosome). However, abnormal chromosome numbers do not affect the sex of the person. Chromosomes contain the genes which give instructions for the body to synthesize important proteins and are responsible for the most basic of our characteristics such as the colour of our eyes, our hair and must more. It is only one pair of chromosomes out of the 23 pairs of chromosomes that are actually the sex chromosomes.

The Y chromosome is the male chromosome. The sex determining region Y (SRY) has drawn much attention as this gene seems to trigger the development of maleness.

It is clear that only males have Y chromosome and thus, if scientists find this chromosome in the maternal blood or urine sample, they can confirm that the baby is a boy. Gender predictions tests with urine have advantages over those with blood because of the type of samples and method of sample collection. Blood samples require a prick of the finger- nothing major- but often a sensation which many people are strongly adversive to and thus, often prefer a gender prediction test with urine.

Boy or girl? It is quite normal for expectant couples to want to know the sex of their child. Gender prediction tests are accurate at confirming the sex of the unborn child. Name choosing, toys and colour schemes for bedrooms are just some of the reasons people choose for doing this DNA baby gender test. The test can be done with either a sample of maternal blood or a sample of maternal urine. The test we offer is a urine test and is the most accurate of all types of baby gender tests available.
