Step 1: Understanding the Concept:
Amniocentesis is a prenatal diagnostic test used to detect genetic disorders in the fetus by analyzing amniotic fluid.
Step 2: Detailed Explanation:
Misuse: Because the amniotic fluid contains cells with the fetus's chromosomes, it can also reveal the sex of the child.
Social Impact: In India, a preference for male children led to the widespread misuse of this technique for sex-selective abortion (female foeticide).
Necessity of the Ban:
1. Gender Balance: It is essential to maintain a healthy sex ratio in the population.
2. Ethical Reasons: To prevent the unethical termination of healthy female pregnancies.
3. Legal Protection: The Pre-Conception and Pre-Natal Diagnostic Techniques (PCPNDT) Act was enacted to regulate such technologies.
Step 3: Final Answer:
The ban is absolutely necessary to curb female foeticide and ensure the right to life for the girl child, preserving a balanced societal structure.
