Amniocentesis is a prenatal diagnostic procedure utilized to assess various characteristics of the fetus, with one of its primary purposes being to determine the sex of the fetus. During amniocentesis, a thin needle is inserted into the amniotic sac surrounding the fetus in the uterus, and a small sample of amniotic fluid is withdrawn. This fluid contains fetal cells, which can be analyzed for chromosomal abnormalities and genetic conditions, as well as for determining the sex of the fetus.

The genetic information obtained from the amniotic fluid sample provides valuable insights into the health and development of the fetus, enabling healthcare providers to offer appropriate medical management and counseling to expecting parents. Amniocentesis is typically performed in the second trimester of pregnancy and may be recommended in cases where there is an increased risk of genetic disorders or when specific fetal abnormalities are suspected based on prenatal screening tests.
