What if girls are born, and I want a boy
Many families, which already has several daughters, certainly wish that they had a male heir. Impatient parents do not want to wait for favors from nature and try to do everything possible in order to have increased the likelihood of the boy's birth.
There is a theory that sperm carrying a Y chromosome (chromosome responsible for male children) are more active than sperm with the X chromosome, but less hardy. When planning the birth of the boy, trying to conceive should be directly at the time of ovulation or before. Determine when you have a ovulation calendar can either method, or by using special tests. Another hypothesis states that during orgasm a woman's body produces alkali, which kills slow "female" sperm, but nimble sperm with Y-chromosomes have time to reach the egg. Do you want to have a baby boy - offer her husband a good try. The French have an opinion, according to which a woman has to follow a special diet in order to have a baby of the desired sex. Ladies who want a boy should be included in your diet meat products, eggs, fish, as much as sharp and spicy dishes as possible. From sour milk products and sweets should temporarily abandon. Most mammals communities built on the principle of one male for several females. Normally, the number of sexual acts committed by a male, is quite large. If male mates often enough, it begins to develop enhanced sperm with X chromosomes (insufficient female - run mechanism of their reproduction). In the opposite situation, when one male falls too many females, on the other hand, the number of sperm will prevail with Y-chromosomes. And humans. The more you have sex, the more likely it is that you have a boy. However, the only method that can guarantee you the birth of a boy is in vitro fertilization in combination with genetic analysis. To begin with several fertilized ova mother, and after analyzing the sex of the embryos. "Unwanted" embryos removed.
