Proponents of the abortion prohibition law of Nigeria (the pro-life group) argue that human life is sacred and the right to life is basic; hence, on no account should one be deprived of that fundamental human right, not even the fetus in-utero. Objectives: This review aims to discuss the concepts of abortion and maternal mortality, analyze the Nigerian abortion laws, discuss issues and controversies with abortion in Nigeria as it relates to maternal mortality and morbidity; and discuss the contributions of this Law on maternal mortality and morbidity in Nigeria. Method: The relevant materials for this article were obtained from search engines such as PubMed and Google Scholar respectively. Conclusion: Reviewed literature reveals that many of the contributory factors to maternal mortality could be avoided if preventive measures were taken and...
