The fact determine the most in determining the sex of the child is the sperm of men. The men sperm chromosome X and Y chromosome, while female egg cells contain only the X chromosome So to get the boys, needed pair X and Y chromosome, while female children to get, only the X chromosome and X.
X sperm size of greater vitality and has a longer (5-6 days), but move more slowly. Y sperm, while smaller-sized, quick death, but move more quickly. Please note, some research shows that children with birth sex men have a higher likelihood of achieving 51%.
Time sex
If you want boys, do have sex before the ovulasi. Conversely do have sex far-distant days before ovulasi if women want children. Ovulasi in the determination of the time women can be done for example by measuring body temperature, the use of the calendar, measuring the thickness or mucus vagina.
Sexual intercourse is done before ovulasi showed that the X sperm will encircle ovarium while waiting at lepasnya and cooked egg cell from ovarium, while Y sperm can not survive long and eventually die. Thus, only the X sperm will fertilize the egg cell so that the X-birth children of women likely to be very high.
When you do have sex before the ovulasi, Y sperm have to move to high speed can be reached egg cell that has been cooked, while the X sperm left far behind. It will allow the birth of sons.
Consumption of certain foods
When you consume foods low in salt and rich in potassium (like bananas and potatoes), the possibility that the child is born diversified sex with men. However, when often consume milk, nuts and green vegetables, the likelihood that children born is female genital manifold.
The type of work
If women want children, the husband should work in urban areas. A research shows that more than 40% of children born from the father of women who work in the urban environment. Environmental cities generally have terpolusi with chemicals that can kill sperm Y, while the X sperm with a high resistance will still be alive.
The number of sperm
The number of sperm a little more inclined to create babies of women and vice versa. To reach that amount seperma little can be done by maintaining the temperature in the area of genitalia to remain high (for example, often wear shorts or jeans and tight pants) or a husband warm water bath before having sex, and do have sex as often as possible.
If you want to reach the number of sperm that many can do the opposite. Limit the frequency of sexual relations and try to keep the temperature in the area of genitalia should remain cool and cold water bath before sexual intercourse.
The position of having sex
To get girls, do have sex positions that can slow the sperm into the uterus and tubes. Environment vagina, which causes acid Y sperm is very difficult to reach the egg cell so that the dead in the middle of the road. Technical sexual relations that should be strived not to enter the penis in the vagina too. Meanwhile, to get the boys, have sex so that the penis is directed reach the vagina in full. These positions can accelerate the entry of sperm into the vagina, uterus, and the tubes so that sperm Y will pass acid environment in the vagina and can quickly reach the egg cell.
Broadband
Wives who experienced under earlier than her husband is suspected to allow the birth of a baby male. When Broadband, women will produce liquid and the basa is a good environment for the life of sperm Y.
