Methods for female contraception: A model for innovation in drug delivery systems

In 2007, 1.7 billion women were in need of contraception, but only 57% of them were using modern contraceptives. During a woman’s 30-year reproductive life, her contraceptive needs may vary from postponing childbearing to spacing out the births of her children and, finally, to limiting family size. Modern contraceptive methods and their delivery systems reflect these changing needs as well as the challenges associated with the long-term regulation of conception, which are similar to the challenges encountered in developing therapeutics for chronic medical conditions.
