Intentional or voluntary termination of pregnancy before full term is called medical termination of pregnancy (MTP) or induced abortion. MTPs are considered relatively safe during the first trimester, i.e., upto 12 weeks of pregnancy. Second-trimester abortions are much more risker.
MTP is comparatively safe upto 12 weeks of pregnancy. It becomes more risky after the first trimester period of pregnancy as the foetus becomes intimately associated with the maternal tissues.
