Good afternoon! Tell please that such a biopsy of a chorion and whether there are other methods of definition of a floor of the child on an early duration of gestation.

[Nekrasova N.J.]

On a duration of gestation till 10 weeks a unique method of definition of a floor of a fetus - a biopsy of a chorion. Through an abdominal wall (or through a vagina) under the control of US, over a wall of a uterus enter a needle, take away a few or a little;little bit material vorsin a chorion (the placenta is then formed of them), a fetus do not touch or tamper with. Then this material investigate or research in laboratory - chromosomes of a fetus look. If will find Y wait for the boy if X the girl.
