Longer-Lasting Contraception

Despite their convenience as contraceptives, "the pills" have their draw backs, one of which is that a woman must be careful to take 20 or 21 tablets a month on a precise schedule. Now researchers have told the American Association of Planned Parenthood Physicians that they are making progress in the search for an equally effective contraceptive to be given by injection no more often than once a month.

Trade-named Deladroxate by E.R. Squibb & Sons, the experimental drug is a combination of female hormones, essentially the same as in the familiar pills. Two doctors reported that the injections appear to be 100% effective in suppressing ovulation. About 500 women are now getting the birth-control shots, and Squibb is planning a test to include up to 5,000 women.

While most women in the U.S dis like the needle, some prefer it, and more do so in other countries. But for home use, Squibb hopes eventually to bring out a one-pill-a-month form.
