Mirena
2001-nowadays
When the Mirena starting time hit the Us market, and then few women were using IUDs that many doctors didn't even know how to insert them. Today, the devices are recognized equally safe, and ii 1000000 US women have a Mirena.

Jeffrey Peipert's theory about how to foreclose unplanned pregnancies isn't complicated. In 2007, Peipert, an obstetrician-gynecologist at Washington Academy in St. Louis, began a groundbreaking report of women's preferences when information technology comes to nativity control. His team began recruiting 10,000 women of childbearing age, counseling them on available contraceptives and offering them whichever course they wanted, free of charge. The goal was twofold: to run into whether more women picked contraceptives that they didn't really have to recall nearly (as opposed to, say, taking a pill every mean solar day) and whether those "forgettable" methods in plow reduced unwanted pregnancies and abortions.
Peipert'southward hypothesis: The preferred contraceptive would be highly effective and, once activated, require no intervention for years. Forgettable. And in fact, such a device has been around for eight decades, in the form of the intrauterine device, or IUD. But this forgettable contraceptive has been all merely forgotten itself. And that's a shame. While nativity control pills fail nearly viii percent of the fourth dimension, less than 1 percent of women with an IUD get significant. That'southward about the same every bit the pregnancy rate in women who've been surgically sterilized. But when you remove an IUD—boom, fertility rebounds.
Contraceptive Comeback: The Maligned IUD Gets a 2nd Chance
past Jennifer Couzin-Frankel (52.five MB .mp3)Subscribe: Wired Features PodcastThe trouble is, IUDs take been at the bottom of the contraceptive heap for years, the victim of bad press and a four-decade-old scandal. But Peipert is finding that you can permit the past go—of the eight,300 women who have received counseling in his report and so far, about fifty percent have chosen an IUD, making it by far the most popular choice.
IUDs are on the verge of a remarkable return to popularity. Nationally, v.5 percent of women using contraception choose them. That sounds unimpressive, merely it'due south the outset fourth dimension in more than 20 years that the number has risen in a higher place two percent; in 1995, it was ane.3 percentage. By that baseline, v.five percent represents a ocean change. And a few pharmaceutical companies believe that number is poised to grow. Only 2 IUDs are on the market in the The states, but 2 more are in late-phase clinical trials. Acquirement for the Mirena, an IUD made by German drug company Bayer, went from $219 one thousand thousand in 2006 to $714 meg in 2010; sales of oral contraceptives cruel two percent over the aforementioned flow.
What happened? A small contingent of doctors and researchers never stopped believing in the IUD even when a medical scandal almost erased it from history. The ultimate set-it-and-forget-it contraceptive is finally making a comeback.
When information technology comes to the intertwined histories of mod birth control and the sexual revolution, the pill gets all the attending. Approved by the FDA in 1960, information technology obviously did a lot to enable sexual freedom and women'southward rights. Just hormone levels in early versions of the pill were almost 10 times higher than they are today, and newspaper manufactures and medical journals soon began documenting health risks like breast cancer and heart attacks. The 1969 book The Dr.'s Case Against the Pill argued that safety risks abounded, and in a Senate hearing on the pill'due south wellness risks, women'south rights activist Alice Wolfson jumped up from the audience and demanded to know why there wasn't a birth command pill for men.
All that controversy primed IUDs for takeoff. Somewhat unbelievably, no one is quite sure how they work, merely the theory goes like this: The human being uterus has one overriding purpose, which is to protect and sustain a fetus for nine months. If y'all stick a poker-bit-sized bit of plastic in there, the body reacts the way it does to whatsoever foreign object, releasing white blood cells to chase after the invader. Once those white claret cells are gear up costless in the uterus, they start killing foreign cells with efficient zeal. And sperm, information technology turns out, are very, very foreign. White blood cells scavenge them mercilessly, preventing pregnancy. In copper- containing IUDs, metal ions dissolving from the device add another layer of spermicidal action.
By the early on 1970s, 17 IUDs were under development past 15 different companies. The issues started with the fourth one to actually striking the market: the Dalkon Shield. AH Robins (which also made ChapStick and Robitussin) marketed one version of it every bit a smaller choice for women who didn't have children. Similar all medical devices at the time, the Shield wasn't vetted by the FDA. While drugs got careful screening, safety and efficacy claims on device labels did not. The FDA stepped in merely if people started reporting issues.
And study they did. Women with the Shield came to doctors ravaged by infection. Some complained of uterine haemorrhage or pain during sexual activity. In others, the symptoms were less severe, like vaginal belch or vague intestinal hurting. Doctors diagnosed some of them with a condition called pelvic inflammatory illness—PID—which can exist caused past chlamydia and gonorrhea or by normal vaginal leaner. The women took antibiotics and commonly got ameliorate, though a few rare cases led to hysterectomies. Furthermore, the Shield had a higher failure rate than originally reported, and some women who became pregnant with the Shield in place experienced spontaneous septic abortion, a miscarriage complicated by infection. At least 18 died. In 1974, faced with a overflowing of Shield-linked complaints, AH Robins took it off the market place.
The fallout persisted for years. Some women who never had symptoms of PID—and others who got treatment and thought they had recovered—afterwards learned that their fallopian tubes were damaged by scar tissue, rendering them infertile. Those users brought more than 400,000 lawsuits against the company. Panic spread; eventually the IUD market cratered. AH Robins went bankrupt in 1985; a year later, public service announcements on TV urged women to take their Dalkon Shields removed. A trust set to recoup the injured somewhen paid out near $3 billion.
By 1986 in that location was just 1 IUD left on the market, and about no one was ownership it. The devices were commercial losers. Simply the scientific discipline of the IUD remained an intriguing puzzle. Women in dozens of countries outside the US were using them in droves. Studies in the 1970s, earlier the Dalkon Shield panic really took off, gave IUDs glowing reviews. Studies later said they were greatly unsafe. Which were correct?
In a way, the respond turned out to be both. Almost IUDs were fine; the Shield was bad news. IUDs have a thread dangling downward from the uterus into the upper function of the vagina to brand them easy to remove. ("Y'all say, 'Cough,' and you pull," one doctor says.) The thread on the Shield was a complect of several strands of nylon-encased filament. Other devices accept only a single strand. As cases of pelvic inflammatory disease soared, speculation grew that bacteria from a sexually transmitted disease could drift up the threads within the nylon lining and into the uterus. David Hubacher, an epidemiologist at Family unit Health International who has been studying IUDs for decades, likewise suspects that because the Shield was marketed to younger, presumably more sexually active women, the users may have had higher disease rates, putting them at greater risk. By the 1990s, researchers were finding that insertion itself pushed vaginal bacteria upwards into the uterus, causing problems. That'south easy enough to avert with practiced sterile procedure.
But that wasn't enough to erase fears that all IUDs caused infertility, just every bit the Dalkon Shield had. So in September 1997, Hubacher attempted to disentangle the problems. His team started working in Mexico City public hospitals, recruiting about i,300 women battling infertility and another 600 who were meaning. Whether the women had once had an IUD proved irrelevant to whether they could get pregnant. Only when the researchers tested the women's blood for antibodies to the sexually transmitted disease chlamydia, they constitute a stiff correlation. "If you separate all these dissimilar factors, what stands out is previous exposure to chlamydia, not an IUD," Hubacher says. "It'southward the bacteria that'southward causing the problem."
Times had also changed. In those exciting days of sexual freedom, AIDS was non a worry, and few used condoms. Doctors today speculate that STDs were more widespread than was actually existence detected. It besides wasn't possible then to diagnose diseases past testing for tiny bits of Dna; merely women who actually showed symptoms got treated. Asymptomatic women still got their IUDs.
The new research and thinking on IUDs had important implications for the futurity of the device. For i thing, information technology'due south articulate that doctors should not put it into women who have an active STD infection. (And even then, information technology'south but bacterial infections like chlamydia and gonorrhea that are problems; infection with the widespread human papillomavirus doesn't disqualify anyone.) For another, inserting it under sterile conditions is paramount. To the people running these studies—and the doctors who read them in medical journals—the results were reassuring. There was naught incorrect with IUDs as a technology.
Marie Foegh grew up in Denmark and trained in Copenhagen every bit an ob-gyn. She came to the US more than than 30 years agone, planning to stay just a couple of years, merely never left. In 1999, she became director of clinical R&D for female health care at a pharmaceutical company called Berlex. And when she took the chore, she institute out that her corporate masters at the German pharma giant Schering wanted to bring to the US an IUD called the Mirena. Introduced in Finland in 1990 and so fabricated available in dozens of countries, the device, the company hoped, might accept a shot at getting a viable piece of the American market place.
Nigh modern IUDs incorporate copper, which has an assortment of benefits, including increased immovability and effectiveness. They're also free of hormones and can exist fabricated cheaply, a boon for women in developing countries. But copper IUDs can cause heavy menstrual bleeding and cramping. The Mirena solves that problem by forgoing the metal for a synthetic version of the hormone progesterone. Here again, the style of action isn't completely understood, merely researchers suspect that the hormone thickens cervical mucus, which makes information technology near incommunicable for sperm to swim upstream. Information technology may likewise sparse the uterine lining, rendering it inhospitable to an embryo should fertilization occur. The hormone-based IUD has the opposite side effect of the copper ones: It sometimes leaves women with little uterine lining to shed, so they hardly become any period at all.
As good equally it was, the Mirena yet faced problems: Few US doctors knew how to insert IUDs. And since the Shield debacle, the FDA had begun regulating IUDs and medical devices far more than forcefully. "We knew it would be a big undertaking," Foegh says. "We couldn't beget for annihilation to get incorrect, because so people would scream 'Dalkon Shield!'" European clinical trials would satisfy the FDA, but Foegh knew that having the FDA's seal of approving wasn't enough; Berlex would take to invest in educating doctors, and for a time the company would likely lose money equally sales were offset by educational costs.
In Dec 2000, the FDA gave Berlex the green light to get-go selling the Mirena in the U.s.. The company began educating doctors aggressively, starting with those in large practices or hospitals, where their skills could spread to other physicians. The pharmaceutical visitor taught them to utilize a speculum to help guide the insertion, to rinse the neck and the vagina with an antibacterial solution, to apply a tenaculum (a kind of forceps) to go along the neck steady, and to mensurate the depth of the uterus with a thin rod chosen a sound to ensure that the IUD would exist put in the right spot. In one case it'due south at that place, the physician flips open the arms of the IUD, wedging information technology in place.
Berlex likewise made a clever conclusion about marketing: It sought FDA approving only for women who already had children, skirting concerns most fertility. The educational activity programme continued for about iv years, Foegh estimates, and sales grew slowly during that time. In 2006, Bayer bought out Schering, and it continues to manufacture the Mirena—merely without Foegh. She left a couple of years afterward to become chief medical officer at Agile Therapeutics, where she works on new contraceptives.
Meanwhile, a competitor to the Mirena experienced a similar resurgence. In the early 2000s, United states of america venture capitalists looking for sleepy, underperforming products with big sales potential had come across the ParaGard, a copper IUD approved in 1984 that never had whatsoever marketing heft behind it. They formed a company chosen FEI Women'southward Health, purchased marketing rights to the ParaGard, and hired a New York ob-gyn named Laura MacIsaac—who happened to have a copper IUD herself—to be their chief medical officer. "It was a big title for a small job," MacIsaac says, since the company had only one product.
FEI trained a small sales force, modernized the ParaGard literature, and sought FDA approval for updated, less-restrictive labeling; the ParaGard is approved for women with and without children. It didn't have long for sales to grow enough that other companies took detect. Even after a series of corporate acquisitions, the ParaGard is still on sale today.
What was still missing was broad support from the medical community. Eve Espey, an ob-gyn at the University of New Mexico, helped change that, non because of her training so much as her unusual life story: Her freshman year at Harvard, Espey got pregnant accidentally and dropped out. In 1979, right afterwards giving nativity to a baby male child whom she would raise alone, she had a copper IUD inserted. She subsequently finished college and medical schoolhouse, and when her son was 12 they moved to a rural surface area of New Mexico, where she worked at the Gallup Indian Medical Eye. At the time, the canton had 1 of the highest teen-pregnancy rates in the United states of america. It became clear to Espey that curt-term methods like the pill just weren't doing the job for her patients. They required too much consequent effort on a woman's part. "In that location'southward such a huge gap between perfect and typical use," she says.
In the belatedly 1990s, Espey was researching her master's project on the attitudes of Navajo-area medical providers toward IUDs when she came across guidelines issued by the American Higher of Obstetricians and Gynecologists. The document was woefully out-of-date. Crafted in 1992, information technology recommended IUDs for older women who'd already had children, and discussed liability for products that had been discontinued. In 2001, Espey emailed a friend on an ACOG committee and offered to rewrite the guidelines herself.
Equally it happened, ACOG was already reviewing the show. Espey's enthusiasm fit right in. "She fabricated this a very competitive priority," says Janet Chapin, director of ACOG's division of women's health bug. "You need a stimulus one-half the time, similar any organisation." Espey wrote a first draft, which then was filtered through layers of bureaucracy. In 2005, ACOG released a practice bulletin urging greater apply of IUDs, and in 2007, it suggested that IUDs "should be considered equally first-line choices" for teenagers. The IUD was out of intensive care and on its manner to recovery.
One of the places IUDs are already making inroads is on American college campuses—thank you to physicians like Melanie Gold, who treats students at the University of Pittsburgh. Now 48, Aureate grew upwardly in Paterson, New Jersey, and in the 1970s often hung effectually Greenwich Hamlet with her father, an ophthalmologist. He wore leather pants, a leather vest, and a leather hat with chains on information technology and had several attractive male friends. One solar day when Gold was xiv, out walking the family'southward blackness standard poodle with her dad, she asked him if he was gay. "He's like, 'Oh give thanks God you lot finally asked me.'" He told her he was, and that her mother was, also.
Gay Pride Day became a family unit holiday. Gilded's parents (who then slept in dissever bedrooms and are now in same-sex relationships) spoke openly with her and her younger twin sisters nearly everything from anal sexual activity to orgasms. Afterward Gold completed her preparation in pediatrics and adolescent medicine, she briefly performed abortions before moving to Children's Infirmary of Pittsburgh. In that location she studied emergency contraception in teenagers and focused on the bread and butter of adolescent medicine: acne, eating disorders, and contraception.
Gold had kept up with the literature on IUDs and came to believe they were a good option for adolescents. Merely she knew the contraceptive wasn't making its style to young women. She spent a year trying to bring the device to her infirmary, only despite initial encouragement, officials told her they couldn't effigy out how to nib insurance companies for IUDs. When she moved to the academy in 2008, Gold was at last able to set up an IUD program, bringing in a colleague from San Francisco to assistance train the staff.
Despite Gold's efforts, getting an IUD at Pitt today tin can exist a lone experience. The aforementioned is true on other campuses. "Everybody who has hormonal birth control tin talk to each other," says Kate Schnuriger, who got an IUD from Gilt in 2009, at the start of her senior yr. "But with an IUD, there's really nobody. Nobody I knew had it. Nobody was in that location to hold my mitt and help me through this." Her mother, who works equally a secretary in a medical role, told her IUDs weren't prophylactic for childless women.
Every bit much equally Schnuriger loves her IUD now, the first mean solar day wasn't easy. The insertion was traumatic: For many women it feels like bad menstrual cramps. Information technology was worse for Schnuriger, who was tense going into the date and says she almost passed out from the pain. Just once her IUD was in place she felt fine, even making it to her job in the anthropology museum that afternoon.
Despite ACOG guidelines, despite FDA approval of the Mirena, misconceptions abound. Jeff Peipert recalls one of his study participants who received an IUD three years ago, when she was 16. Subsequently, her mother told her she wouldn't exist able have children if she kept it in. "We told her nosotros didn't call up at that place was an increased take a chance," Peipert says. "She said, 'I just want it out.' And then we took out this 19-year-former's IUD."
The comeback, in other words, could still be batty. Even though many more than doctors are comfortable with the IUD, a generation of doctors didn't get do inserting it. And if they don't know how to put one in, they're less likely to recommend it equally an option. Besides, the devices are expensive—the ParaGard costs $500, the Mirena $850. "Information technology's absolute highway robbery that these companies charge so much," Espey says. "If you went to Habitation Depot and got the raw materials for a copper IUD, information technology would cost less than 5 cents." And the hormones don't contribute much more to the toll, she adds.
In fact, amortized over years of use—10 for the ParaGard and 5 for the Mirena—an IUD is far cheaper than nascence control pills, which can cost $30 or more a month. Just the initial outlay is hard for some women to manage, and it'southward non always covered by insurance. Schnuriger, who comes from a working-class St. Louis family, dissever the $450 cost of her IUD with her boyfriend. She used money earned from a work-written report job to pay her half. If she keeps the ParaGard the full 10 years, it will cease up having cost $3.75 a month.
With new IUDs in clinical trials, the US market is well-nigh certain to expand. A hormone-based IUD "should be available to lots and lots of women on the planet, and it's merely not" because it costs and so much, says Victoria Hale, CEO of Medicines 360, ane of the new IUD developers. The company hopes that by selling its IUD for pennies in poor countries and more than in the developed globe, information technology tin can make the IUD far more attainable while yet turning a profit.
Likewise, Bayer is convinced that there's a market place for a second- generation Mirena—this one smaller, with slightly lower hormone levels. The company has been guarded most its new product. Full results of completed trials aren't bachelor, simply a synopsis posted on the Bayer clinical trials database reported "a trend" toward less painful insertion. A wider test on nearly iii,000 women will presumably offer clearer results. Leo Plouffe, vice president of medical affairs for women'southward health care at Bayer, acknowledged the desire among doctors for an IUD with data backing its safety amidst young, childless women. "It has been an area of business concern among clinicians, non having the data for the Mirena label," he says.
Dorsum in St. Louis, Peipert says information technology volition be a few years before his study shows whether IUDs are driving a driblet in unplanned pregnancies. "The all-time method of contraception is being completely underutilized," Peipert says. We're using methods that are inferior, he says, even though a better i is out there. He makes it sound so simple.
