Ideally, there should be an equal number of boys and girls. The uneven sex ratio indicates that the community favors the birth of boys over girls. An uneven sex ratio leads to unnecessary crimes like trafficking, etc.

Amniocentesis is a medical procedure useful for diagnosing chromosomal abnormalities and other defects in the fetal stage. This test is used for the identification and treatment of disorders.

In India, this medical procedure is often used for pre-natal sex determination, and people abort girl fetuses. Thus, amniocentesis is banned for sex determination in India.

Extra information:

The doctor may advise undergoing amniocentesis as a prenatal treatment throughout pregnancy. The test detects fetal anomalies (birth defects), including Down syndrome, cystic fibrosis, and spina bifida. The majority of the time, the results are normal.

Amniocentesis is often done between 16 and 20 weeks of pregnancy. During this stage, the growing fetus is floating in approximately 130ml of amniotic fluid, which it continuously eats and excretes. A tiny amount of this fluid is removed with a fine needle from the sac around the fetus.

The fluid is analyzed to gain information about the baby, such as its gender, and to detect physical problems such as Down syndrome or spina bifida. DNA testing may also be performed on amniotic fluid samples to diagnose a variety of genetic abnormalities, including cystic fibrosis and fragile X syndrome.

Amniocentesis is only conducted on women who are believed to be at a greater risk of giving birth to a child with a birth defect.
