- <p>Norplant could spur birth control--and stir controversy
- </p>
- <p>By ANDREW PURVIS
- </p>
- <p> For a country in which medical breakthroughs occur with
- dizzying regularity, the U.S. has been disturbingly backward
- in the field of contraception research. Not a single
- fundamentally new birth-control method has been introduced
- since the Pill and the IUD, or intrauterine device, came out
- in the early 1960s. Meanwhile, in several European countries,
- a series of contraceptive innovations has broadened the range
- of methods far beyond what is available in the U.S.--and
- sharply reduced the number of unwanted pregnancies.
- </p>
- <p> Thus many American health experts were delighted last week
- when the Food and Drug Administration finally approved
- Norplant, a long-lasting contraceptive that is implanted under
- the skin. Already available in 16 other countries, the method
- not only is highly effective but also provides five years of
- protection against pregnancy with a single implant. How
- American women will respond to this new alternative, though,
- is not clear, since Norplant's long-term safety has yet to be
- fully studied, and it does have a few side effects. Some critics
- fear that the five-year implant will be used by policymakers
- as a way of forcing contraception on women deemed unfit for
- motherhood.
- </p>
- <p> Norplant is essentially an old contraceptive in a new
- package. Developed by the Population Council, an international
- nonprofit research group, and Wyeth-Ayerst Laboratories, a
- division of AmeriHome Products Corp. of Philadelphia, the
- method prevents pregnancy by using the hormone progestin, which
- with estrogen is the active ingredient in most birth-control
- pills. Norplant consists of six progestin-filled silicone tubes,
- each about the size of a matchstick. In a simple 15-minute
- procedure, a doctor inserts the tubes just beneath the skin in
- a woman's upper arm. Once in place, the tiny cylinders start
- releasing progestin into the bloodstream. The flow continues
- until the hormone is depleted--usually in about five years.
- If a woman wishes to become pregnant earlier, she can have the
- tubes removed, and fertility will be restored in less than 48
- hours. In clinical trials Norplant was remarkably effective.
- During the first two years the implant had one-tenth to
- one-twentieth the failure rate of oral contraceptives, which
- fail 3% of the time. Surveys of women who have used Norplant--a total of 350,000 worldwide--show that 80% are willing
- to stick with the contraceptive for at least one year.
- </p>
- <p> The method does have drawbacks. Progestin causes irregular
- menstrual bleeding in 75% of women who use it. Women may get
- their periods at odd intervals, such as 3 or 7 weeks apart, and
- some could miss one altogether. The periods themselves can also
- be longer, an average of 8 days of bleeding or spotting as
- opposed to the normal 5 days. These effects diminish after the
- first two years, according to the manufacturers. In addition,
- the cost, although less than that of oral contraceptives, will
- be considerable. Wyeth-Ayerst officials will not reveal the
- price until marketing begins in February, but some experts have
- estimated that the implant and the medical procedure together
- will run to about $500, as opposed to an average of $900 for
- five years of the Pill.
- </p>
- <p> Norplant's biggest advantage over other contraceptives is
- that it requires only one birth-control decision every five
- years. The method will be useful to young women who want to
- delay their first pregnancy and to older women who want a
- reversible alternative to sterilization, which is now the most
- common method of contraception in the U.S.
- </p>
- <p> But the same advantages that recommend Norplant to many
- women also raise the specter of abuse. Some health experts fear
- that legislators and judges will try to use the method as a way
- of restricting the reproductive freedom of teenagers, drug
- users, convicted child abusers or even the mentally ill.
- Economist Isabel Sawhill at the Urban Institute, a
- Washington-based research organization, recently published a
- paper in which she suggested that all teenagers be encouraged
- to use Norplant at puberty. "The decision to have a child would
- become a conscious choice--decoupled from the dictates of
- biology, hormones and peer pressure," she wrote.
- </p>
- <p> Sawhill is not recommending the use of force, but some
- experts believe that coercion is an inevitable next step.
- Arthur Caplan, director of the Center for Biomedical Ethics at
- the University of Minnesota, points to a handful of cases in
- the past five years in which judges have tried to require women
- to take oral contraceptives or to force men to take drugs that
- lessen their sexual drive. "There are judges out there who will
- try to use Norplant," says Caplan. Others worry that some
- developing countries will force the contraceptive on women
- without their full consent in a misguided attempt to keep
- population growth down.
- </p>
- <p> The controversy over Norplant highlights a general
- dissatisfaction with the state of contraception research in the
- U.S. Numerous other methods are being studied around the world,
- including a hormone-releasing IUD, a hormonal badge that is
- taped to the arm and releases a contraceptive through the skin,
- a female condom and a hormone-emitting vaginal ring, which a
- woman can insert and remove at will. The French abortion pill,
- RU-486, is being actively considered for approval in several
- other European countries but has not been approved in the U.S.
- Thanks in part to political skittishness about funding
- contraception in the U.S., American women still have a paltry
- array of birth-control choices. Many experts see this
- contraceptive gap as the chief reason why 3.5 million unwanted
- pregnancies still occur each year in the U.S. Policymakers are
- a long way from stopping that national tragedy, but the
- approval of Norplant may be a start.
- </p>
- <p>FIVE YEARS OF PROTECTION
- </p>
- <p> In the procedure, six matchstick-size flexible tubes are
- inserted under the skin in a fan-shaped pattern. The tubes
- contain a synthetic hormone called progestin, which is released
- at a slow, even rate. The drug prevents pregnancy through a
- combination of mechanisms. It inhibits ovulation, so that eggs
- are released regularly, and it thickens cervical mucus,
- preventing sperm from reaching the eggs that are produced.
