The Medical Termination of Pregnancy Act of 1971 aims to provide for the termination of certain pregnancies by registered medical practitioners. It defines key terms like guardian, minor, lunatic, and registered medical practitioner. It outlines the circumstances under which a pregnancy can be terminated, including risk to the woman's life or health, fetal abnormalities, rape, or contraceptive failure. Terminations can be done by experienced doctors in approved government hospitals. Facilities must have appropriate equipment and drugs. Consent is required from the woman, or her guardian if she is a minor or lunatic. Records must be kept privately and securely.
