MTP is intentional or voluntary termination of pregnancy. It is performed to get rid of unwanted pregnancy either due to casual unprotected intercourse or failure of the contraceptives used or rapes.
MTP is also considered when the continuation of pregnancy is harmful either to the mother or to the foetus or both.
MTP is considered relatively safe during the first trimester, i.e., upto 12 weeks of pregnancy.
Second trimester abortions are much more riskier.
