Nowadays, people spend tons of dollars on what some call "designer babies" to buy, so it is normal for parents to ask for ways to predict the sex of baby. Some methods are very expensive, while some are really cheap. Preimplantation genetic diagnosis (PGD), for example, go for about $ 20,000, while natural methods cost almost nothing. Below are six options available to predict the sex of your baby.
Ericsson method
Dr. Ericsson patented this method in use since the year based on the principle that the X chromosomes note are slower than the Y chromosomes that the Y chromosome is responsible for a little boy, while the X chromosome is responsible for a little girl. The method enables the spermatozoa for a period at the top of a column of albumin to flow. They are then separately for fast and slow swimmers. If a couple wants a little girl slowly sperm is used to fertilize the eggs. Fastest sperm artificially inseminated for a little boy. Users of this method claim that it has the accuracy of 85%, especially with the baby.
PGD (preimplantation genetic diagnosis)
The IPR method involves in vitro fertilization (IVR) and is very expensive. The eggs are fertilized eggs from the ovaries of the mother by the sperm of the father in a "baby lab" left to incubate for a few days and then transferred into the woman's uterus fertilized. The success rate is very close to 100%
Microsoft
The centrifugal force is used to separate the X-and Y-chromosome sperm. Desired sex baby (Y for the boy, X for the girl) a of them are selected and used to fertilize the eggs. His success rate is about 75%
Ultrasonic technology
Mainly ultrasound is not intended to predict the sex of the baby, but to check on fetal development. But along the line, doctors use the method to predict the baby's sex. The technology involves a procedure that considers the analysis of the fetus on one screen. The image will then be read, interpreted and used to predict baby gender. Simply, the technician will Ulltrasosnoprapher looking genitals. When male genitals are noticeable, a little boy is expected. The lack of male genitals mean a girl comes. Accuracy of the technique of ultrasound baby gender prediction also depends on the ability of the technician and the equipment used. Of course this is not 100% correct. More pregnancy, the more accurate the prediction.
Amniocentesis. (Amniotic fluid test or AFT)
Typical of older women when chromosomal disorder is suspected. As ultrasound, it is not primarily used to predict the sex of a baby. A sample of amniotic fluid is removed from the amniotic sac around the fetus and investigated the genetic and chromosomal abnormalities.
Another method similar to amniocentesis, chorionic villus sampling (CVS), which is also used to check for chromosomal abnormalities, especially, could also be used to predict the baby's sex. Both methods are invasive and take with them a high risk of miscarriage, but they also have a high degree of accuracy, about 99%
Table Chinese Predictor
Then you have the ubiquitous Chinese chart 700 years. The age of the woman is plotted on a graph versus the previous month of conception. If they respond to B, it's a boy, and when they meet G, you are predicting a little girl. There is no scientific basis, but there is a choice between a girl and a boy, chances are that it will be correct 50% of the time.
In addition to the above, you have the old wives' tale, as an example of how not predict either a scientific base of the baby's sex.
