In theory, with every pregnancy a couple should have a 50/50 chance of having a boy or a girl. And while those odds could dictate a family producing children of predominately one gender, from the standpoint of statistics and probability, the genders should be split equally. And yet, there are many families with children of only one gender, even in larger families with upwards of 3 children or more. It's difficult to say whatever this is due to genetics, the nature of the father's sperm or some other factor, but there are many families who seem to be able to produce one. So it seems that while the genders should be equally split quantitatively, in individual families the numbers might be completely skewed to favor one gender over another.
But the desire to have a child of a particular gender is not the only circumstance in which gender selection comes into play. There are many genetic diseases that are carried on one specific gender and parents wishing to avoid producing a child with that disease may prefer to have children of only one gender.
Regardless of the motivation for wanting a child of a particular gender or the cause of the difficulty in having one, gender selection techniques are available. Backed by years of research, these gender selection techniques are safe and effective. Gender selection can guarantee families the child they always held for. Gender selection can also guarantee a child who gender results it from inheriting a gender-based genetic disorder. Parents should not have to rely on statistics or probability. With gender selection, couples can produce healthy babies of their chosen gender and the family of their dreams.
Using the Ericsson Method
If you want a boy, you select sperm containing the Y chromosome, so that during fertilization, the sperm's Y chromosome will pair up with the egg's X chromosome. If you want a girl, you select sperm containing the X chromosome, so that during fertilization, the sperm's X chromosome will pair up with the egg's X chromosome.
IVF / PGD Technique
After ovarian stimulation, eggs are removed from the mother. These eggs are fertilized in the laboratory using the father's sperm. After cell division, the embryos are checked for their sex. Only the embryos of the chosen gender are transferred back to the mother.
Technological Methods of Baby Sex Selection
The major advantage of using technology in gender selection is that it's generally much, much more accurate in helping you choose the gender than natural techniques are. On the downsides, scientific procedures are much more expensive and often involve methods like in vitro fertilization, which is a turn off for people interested in conceiving naturally.
The most successful method of gender selection is PGD (preimplantation genetic diagnosis). It's effectively a way of choosing the gender of the baby before an embryo is implanted via in vitro fertilization. It's the only way to know for sure you'll be getting a boy or girl, because the gender is known before the embryo is implanted. Other scientific methods generally involve a manipulating sperm count to favor the chances of conception towards a boy or a girl, because it is the X or Y chromosome carried by sperm which determinates the gender of a baby.
