Abortion is the termination of pregnancy that occurs spontaneously or purposely. In the most developed world, abortion is legally allowed for women seeking safe termination of pregnancies. Particularly, when access to legal abortion is restricted, abortion is the resort to unsafe methods. The aim of this review is to necessitate safe abortion and to accentuate the consequences of illegal abortion in case of legal prohibition. We used Pubmed, MedLine and Scopus databases to review previous literatures of safe, unsafe, legal and illegal abortions. Research work and reports from organizations such as World Health Organization (WHO), World Bank (WB) and United Nations (UN) were included. Snowball sampling was used to obtain relevant journals. Abortion is conventional whether it is safe, unsafe, legal or illegal. The intention of the antiabortion policy was to reduce the number of abortions globally. However, instead of decreasing rates, evidences show significant increase in abortions. When abortion is legal, the preconditions to be ensured are availability, accessibility, affordability and acceptability for the safe abortion facilities. When abortion is illegal, risk reduction strategies are needed to decrease maternal morbidity and mortality. We can reduce abortion related morbidity and mortality, whether it is legal or illegal if we can ensure the appropriate access to health care, including abortion services, education on sexuality, access to contraceptives, post abortion care, and suitable interventions and liberalization of laws. The paper reviewed the Mexico City Policy and the US foreign aid strategies and highlighted the evidence based analysis for policy reform. The liberalized abortion law can save pregnant women from abortion related complications and death.
