Contraceptives such as IUDs and implants are finally being embraced by U.S. women after many years of doubts and controversy. In a new study, researchers at the Guttmacher Institute looked at data from the National Survey of Family Growth from 2006 and 2008 and found many more women are using IUDs such as the Copper T or the levonorgestrel intrauterine system (known as Mirena). Similarly, implants inserted under the skin in the arm, such as Implanon, are becoming more popular. The ratio of women using these long-lasting, reversible methods increased from 2.4% in 2002 to 5.6% in 2006 to 2008.

"Trout pout" ? overly plumped lips that are ubiquitous on Hollywood's red carpets ? can afflict any woman who has tried to enhance naturally thin lips. But a technique from Europe that's rolling out across cosmetic surgery practices in Beverly Hills and beyond aims to counteract the billowy, bee-stung lips that are the result of having fillers, collagen and fat injected into the area. PermaLip, an Food and Drug Administration-approved implant that looks like a clear-colored piece of elastic, is now being used in practices in Florida, Texas, New York and California.

Prenatal surgery for the most severe form of the birth defect spina bifida doubled the number of children who were able to walk unassisted by the age of 30 months and halved the percentage who had to have shunts implanted after birth to remove water from the brain, researchers reported Wednesday. The surgery, however, presented some risks to both children and mothers: Infants were more likely to be born preterm and mothers suffered a thinning of the uterine wall that would require all future births to end in a caesarean section.

First breast implants, now jaw implants. The implant news just keeps on coming. The Food and Drug Administration on Monday ordered three manufacturers of temporomandibular joint, or TMJ, implants to study the length of time these jaw implants remain effective before they are removed or replaced because of pain or other reasons. The federal agency reviewed what it called "TMJ implant-related adverse event reports" and found that a substantial number of patients had implants replaced within three years or less.

For years, Michell Anne Kimball of San Diego considered breast augmentation but worried about the health risks. Three years ago, the 47-year-old decided the time was right, consulted with a plastic surgeon and, after four more months of pondering, received silicone implants. She loves them, she said. And she continues to agonize over them. "Are these things safe or not? Are we ever really going to know?" Though modern breast implants have been around for decades, questions of safety continue to plague augmentation even as the artificially enhanced bosom has become common.

Breast implants made news recently when the Food and Drug Administration said they might be linked to a rare form of cancer in a very small number of women.
