Chuck Colson reflects on the connection between sex-selective abortions and the increased demand for prostitution in a post here. He mentions a law review article by two Loyola law students, Kristi Lemoine & John Tanagho, Gender Discrimination Fuels Sex-Selective Abortion: The Impact of the Indian Supreme Court on the Implementation and Enforcement of the PNDT Act, 15 U. Miami Int’l & Comp. L. Rev. 203 (2007). Another student piece discussing the connection between sex-selective abortion and prostitution in India is LESSONS FROM PUNJAB’S “MISSING GIRLS”: TOWARD A GLOBAL FEMINIST PERSPECTIVE ON “CHOICE” IN ABORTION, 97 Cal. L. Rev. 905 (2009).
Two more recent law review articles focus on sex-selective abortion and Chinese sex trade, Gendercide and the Cultural Context of Sex Trafficking in China , 32 Fordham Intl. L.J. 731 (2009) and David Smolin, THE MISSING GIRLS OF CHINA: POPULATION, POLICY, CULTURE, GENDER, ABORTION, ABANDONMENT, AND ADOPTION IN EAST-ASIAN PERSPECTIVE, 41 Cumb. L. Rev. 1 (2011).
A summary of various efforts to address human traffiking with links to relevant conferences, etc. is here.
