Overview of modern contraception.

The large-scale initiatives to address the global unmet needs for family planning (FP) have gathered and compelled scientists, providers, program managers, and other stakeholders (including users) to re-examine the various methods of modern contraception, focusing on those that are proven to be more effective (long-acting reversible contraceptives and permanent methods), historically more widely used (oral contraceptives, condoms), and in development (male hormonal contraception). Implementing FP programs requires an understanding of the human rights principles underpinning the delivery of contraceptive services, the various indicators related to demand, need, and use (demand satisfied, unmet need, and contraceptive prevalence), and its effectiveness (perfect or correct use and typical use), which will be presented in this article. Tools and guidance documents developed using the best available evidence have also been listed in this review article. This issue will also look at new initiatives about providing care (self-care), and key population groups (post-pregnancy and adolescence). The clinical use of the methods should go hand in hand with the programmatic initiatives to ensure that women, men, or couple take up the appropriate method of choice and continue using these based on their reproductive health goals.
