The track record of human males taking care of birth control is not exemplary.
In societies where birth control is not taboo--like ours, it is usually still the woman in charge of not getting pregnant. True, there's no even distribution of the risk of pregnancy, but there's also no even distribution of responsibility.
Krystale E. Littlejohn, a University of Oregon sociologist, examines the situation in the book Just Get on the Pill: The Uneven Burden of Reproductive Politics.
Littlejohn's work focuses on race, gender, and reproduction, and here she explores the allocation of birth control responsibility in cultural, not strictly biological, terms.
