The mission of PSI is to measurably improve the health of poor and vulnerable people in the developing world, principally through social marketing of family planning and health products and services, and health communications.
In 2009 alone, PSI prevented an estimated 3.5 million unintended pregnancies and over 17,000 maternal deaths, and enabled millions of couples to plan their families.
Over the past three decades, PSI has expanded the contraceptive methods in its portfolio from male condoms and oral contraceptives to include injectable contraceptives, intrauterine contraceptive devices (IUD), emergency contraception pills, implants, female condoms, voluntary sterilization, and fertility awareness methods such as the Standard Days Method using Cyclebeads®. PSI’s RH platform has also grown to address maternal mortality through the prevention of post-partum hemorrhage and sepsis, and the prevention of unsafe abortion.
