Intentional or voluntary termination of pregnancy before full term is called MTP or induced abortion.
45 to 50 million MTPs are performed in a year all over the world (i.e. 1/5th of total number of conceived pregnancies).
MTP helps to decrease the population.
Because of emotional, ethical, religious an social issues many countries have not legalised MTP.
Government of India legalised MTP in 1971 with some strict conditions to check indiscriminate and illegal female foeticides which are reported to be high in India.
