Emergency Contraception's Mode of Action Clarified
Emergency contraceptive pills, a hormonal treatment that can prevent
pregnancy if taken within 72 hours of unprotected intercourse, have been
the subject of heated debate. At issue is the method’s mechanism of
action: does it prevent the meeting of egg and sperm, or does it prevent
a fertilized egg from implanting in the uterus? Recent research by
members of the Population Council’s International Committee for
Contraception Research (ICCR) and other scientists shows that the most
popular method of emergency contraception appears to work by interfering
with ovulation, thus preventing fertilization, and not by disrupting
events that occur after fertilization.

Postabortion Complications Prevalent in Pakistan
Determining the levels of induced abortion and postabortion
complications in various regions is essential because of the
consequences these experiences have for women’s health. The Population
Council has studied abortion and postabortion complications around the
world, most recently in Pakistan. This comprehensive research has
revealed a high level of unwanted pregnancy, induced abortion, and
postabortion complications in that country.
