Explanation

Amniocentesis is a withdrawal of a sample of the fluid (amniotic fluid) surrounding a fetus in the uterus by piercing the amniotic sac through the abdominal wall, under direct ultrasound guidance. As the amniotic fluid contains cells from the fetus, cell cultures enable chromosome patterns to be studied so that prenatal diagnosis of chromosomal abnormalities can be made. Certain metabolic errors and other abnormalities, such as spina bifida, can also be diagnosed prenatally from analysis of the cells or of the fluid. As this technique also helps in the detection of the sex of the unborn fetus, it has been banned in order to legally check increasing female foeticides.
