The child's sex

Pregnancy is the complicated process. And when parents decide to have the baby, usually one of parents expects to have the baby of the certain sex. Usually fathers want to have sons while mothers want to have girls. In my opinion, the sex doesn't matter. The most important thing is the health of the baby. According to statistics the pregnancy with boys comes more often than the pregnancy with girls. The statistics tells a lot. For example, young and healthy families usually have boys, and older families usually have girls. Probably the fact that there are more chances to have the boy than the girl is connected with the fact that the spermatozoon with the Y chromosome is more active than the spermatozoon with the X chromosome and that is why it has more chances to reach the ovule faster. But the spermatozoon with X chromosome is more viable and has more chances to survive in uterine tube. So, one of the ways to predict the birth of the baby of the certain sex is based on such ability of the spermatozoon. First of all it is necessary to determine the date of ovulation. That is why if your period is regular, then the day of ovulation is constant and it is possible to make not rather complicated calculations. If you want to have the daughter the conception must happen not later than 2-3 days after ovulation. If you want to have the boy it is not recommended to have sex during 7 days before ovulation. And the conception must happen the day before ovulation or the day of ovulation. This method is efficient in 80% of all cases. With the help of US it is possible to get to know the sex of the baby after 22 weeks of pregnancy.
