It is more of a researcher’s method and is not a very common practice. The process involves a thin laser light that will be put on the sperm, the sperm is also dyed to a florescent color. Then the sperm will be sifted through using a cell sorter. After this the sperm will be measured out and separated by chromosomes. This means sperm congaing "x" chromosome will be divided from sperm containing "y" chromosome.

The technique tends to be time consuming. The result of a full days work will be to come up with one fully separated sperm sample which then can be inseminated by artificial insemination that may or may not be successful.

In the only publicized study of this method, the research shows that there were only 14 cases that were even advanced enough (the women we’re far along enough in pregnancy or they had given birth) to determine the sex of the baby. Of the 14 cases, 13 of those were female baby’s.

With all information provided, my assumption is that if a couple we’re able to access this method the only thing it might allow for is a heightened chance of conceiving a baby girl.

Dr. Hilton Kort of the reproductive biology association has said that this method should only be used when there is a great risk of genetic birth defect or disease. Dr. Joseph Schulman is the director of the genetics and IUV institute. He supported Dr Kort’s claim by adding that families are trying to use techniques that were developed to and only safe for predicting genetic disease as a way of picking their baby’s gender.
