It forms the water bed for the fetus. So the fetus has the ultimate form of protection. It gives space for the fetus to move around. Fetus continuously drinks the amniotic fluid and excrete the same. So it gives training to the kidney to do it's work after birth.
There are two methods for sampling cells from a fetus: amniocentesis and chorionic villus sampling (CVS). AmniocentesisAmniocentesis involves analysing a sample of the fluid surrounding the fetus in the womb (the amniotic fluid). It is performed from 15 weeks of pregnancy onwards.Using ultrasound to guide the way, a fine needle is inserted through the mother's abdomen and into the fluid surrounding the fetus. 20ml of amniotic fluid is removed and sent for analysis.Chorionic villus sampling (CVS)CVS analyses a sample of the placenta and is performed from 11 weeks onwards.Using ultrasound to guide the way, a needle is inserted through the mother's abdomen into the developing placenta. Suction is applied and a small sample of tissue is sent to the laboratory.See: http://www.netdoctor.co.uk/diseases/facts/chromosomeabnormality.htm
Yes it is possible, but you might want to check into that because my mother had to get her uterus stitched up so the baby wouldn't come out to early. My pregnancy had no suc hproblems like that though so I don't have first hand experience.
Amniocentesis can be done no earlier than the fourteenth week of pregnancy. Sufficient amniotic fluid has to be present to do an amniocentesis. Amnios can be done well after 15 weeks but you shouldn't have one before then.
