...September, and is manufactured under the trade name Mifepristone. Administered within the first five weeks of pregnancy, it causes abortions by blocking the action of the hormone progesterone, thus provoking the uterine lining to slough off the embryo. If taken with a prostaglandin, a substance that makes the uterus contract, RU 486 is about 95% effective. Some 8,000 women have used the pill, which has been available only in hospitals and medical clinics and has no harmful side effects...
...which was first incorrectly dubbed the "morning-after pill" when it was discovered in 1982 by French researcher Etienne Beaulieu, . have found it to be effective 95% of the time when taken during the first five weeks of pregnancy in conjunction with a prostaglandin, a substance that causes the uterus to contract. According to last week's Journal, Dutch researchers found epostane to be 84% effective in women five to eight weeks pregnant. Suction abortions, the usual surgical method, have a 96%-98% success rate. While both drugs allow women to avoid the dangers of surgery and anesthesia, they...
...growth, including head and brain size, may be impaired, strokes and seizures may occur, and malformations of the kidneys, genitals, intestines and spinal cord may develop.

A thimble-shaped device made from rubber or plastic and measuring about 1 1/2 in. in diameter, it fits snugly over the cervix, or neck of the uterus, and is held in place by suction. The diaphragm is bigger and more fragile. A thin rubber dome averaging about 3 in. wide, with a flexible rim, it is placed between the pubic bone and the vaginal wall and kept in place by tension. Both contraceptives are used with spermicide...
...most important thing is that this procedure is preventable," says George Annas of the Boston University School of Medicine. Multiple fetuses often result from in vitro fertilization, in which numerous embryos are transferred into the uterus in the hope that one will "take." As a result, some clinics now use fewer embryos. Multiple conceptions have also occurred in women taking fertility drugs; many could be avoided, say obstetricians, if dosages were prescribed more carefully. Such measures would probably lengthen the time that it takes couples to conceive, but that seems a small price to pay for avoiding what must...
