Simple way based on biological differences between cells containing spermatozoa with the X chromosome containing Y chromosomes The difference between the two sperm cells as follows.

First, the size of X sperm cells bigger, so the slower the motion, while Y sperm move faster because the smaller size. Second, X sperm cells are more resistant to acidic substances, while Y sperm are more resistant to the alkaline substances.

Based on these biological differences and made a simple attempt to separate the two types of spermatozoa in the planning of a baby's sex.
First, by setting the time sexual intercourse. Sexual relations conducted in time to allow fertile Y spermatozoa reach the egg first, which is expected to produce a baby boy. If done about two days before or after the fertile, is expected to produce a baby girl.

Second, by using substances that are acids or bases. If you want a baby boy, do rinse the vagina with the alkaline material before sexual intercourse. Conversely, if women want a baby, do rinse with acidic substances before sexual intercourse.

Third, by arranging techniques that sexual intercourse orgasm can be arranged. If you want a baby boy, the wife must first orgasm to the atmosphere inside the vagina becomes alkaline. Conversely, if a woman wants a baby, the wife should have an orgasm and then to the atmosphere in the vagina remained acid.

Of course, this simple method is not guaranteed to give a definitive result. In fact, failure is high because for many people is not always easy to determine when the right moment fertile, and how to arrange for an orgasm first, or later.
