All of us have at some point in our lives wished that we could decide with some certainty that we would have the boy or girl of our choice. Gender selection of offspring has been a quest of mankind for ages, not just from the time of the Greeks and the Romans.

Western countries are believed to have spent over a billion dollars in research of this kind. Old wives tales and folklore have thrived on our desire to have the baby of our choice. The ancient Chinese are reported to have devised a system that was some 65 percent accurate.

But first, why would anyone want to choose the gender of ones baby?

Any baby, boy or girl, is a gift of nature, and should be welcome as such?

Over the years, different reasons have been given for preferring a baby of a particular gender.

The most important reason, and the one which I strongly support, for trying to influence the gender of your baby at the time of conception, is medical. Many disabilities are now known to be transmitted across generations through genes. Many of these disabilities are gender specific. For example, a woman herself may not suffer from a gene-linked illness, but she will convey the disease-causing gene to her male children who will then be affected by the disease.

There are about 350-plus X-linked disorders (diseases that only male children inherit), some of them fatal, such as hemophilia, muscular dystrophy and X-linked hydrocephalus, and gender selection is almost a compulsion for such families. If the woman is a known carrier of an X-linked disorder, sex selection is the one way to try and prevent passing on the disease to a male child.

Some may accuse these couples of playing God. But couples attempting gender selection usually have practical reasons for doing so. Quality of life becomes an issue for both parents and child. For instance, will the child be so handicapped that he is in perpetual discomfort? What will happen to this child if the parents are no longer able to care for him? Can the parents' marriage weather the stress of raising a boy who will need constant nursing and who will never live a normal life?

The same argument of playing God can be used against contraceptives and abortion?

One must make the choices in life that one believes are necessary. Sometimes gender selection, attempting to improve the odds in favour of conceiving a boy or girl as desired, is a choice one must make.
