nformation is scarce about the extent to which official development assistance (ODA) is spent on reproductive health to provide childbirth care; support family planning; address sexual health; and prevent, treat, and care for sexually transmitted infections, including HIV. We analysed flows of ODA to reproductive health for 2009 and 2010, assessed their distribution by donor type and purpose, and investigated the extent to which disbursements respond to need. We aimed to provide global estimates of aid to reproductive health, to assess the allocation of resources across reproductive health activities, and to encourage donor accountability in targeting aid flows to those most in need.
