Natural methods of determining the sex of the child
Shettlsa method - one of the most known methods of planning sex of the child.His doctor suggested Landrum Shettls.The technique consists of choosing the correct time intercourse depending on the phase of the female cycle and the use of certain products.
Shettls In his book explains that the sperm containing the male Y-chromosome, smaller, faster and live shorter time than sperm with the female X-chromosome.Therefore, if a couple wants a boy, you should choose the sexual intercourse as close to ovulation.Thus, the male sperm get to the egg faster.
In addition, Y-sperm can benefit from the advantage, being as close as possible to the cervix.This can be achieved by selecting the position of the "man in the back."
If parents want a girl, they need to have sex in the missionary position for two to four days before ovulation to the time of the release of the egg were only X-sperm.

probability of success in planning the sex of the child can be even higher if the use of high technology.Experts believe that MicroSort - a method that allows to separate the sperm from the male and female chromosomes - the best achievement to date.
procedure involves separation of X and Y sperm cells with a laser.After separation, the necessary samples are used for the artificial insemination of women.The developers of the method have reported 91% success rate for couples wanting a girl, and 73% - for the boy who wanted to.
is not the only high-tech method of sex selection.Other, more controversial methods - pre-implantation genetic diagnosis (PGD) and chorionic villus sampling (CVS) - both methods are used to determine the probability of disease, but may also be used for sex determination.
In order to determine the sex of the embryo PGD involves the study and placement in the uterus only embryos of the desired sex.In CVS chromosome investigated embryo at early stages of pregnancy.Experts do not recommend these techniques for sex determination.
