According to a Food and Drug Administration analysis, women are increasingly experiencing bad reactions of the sterility device called Essure, together with persistent pelvic and abdominal pain. The number is reported to have increased about 20 times from 2011.

Essure, which is a metal and polyester coil from Bayer AG, is inserted in fallopian tubes of a woman to make her sterile. It is considered a substitute to tubal ligation, which is a surgical procedure, and other methods intended to offer permanent birth control. In 2002, the implant was given green signal by the FDA.

There are many reports of adverse events as the agency is reported by hospitals, manufacturers and the general public, and publicity or lawsuits also have an effect on such reports. Therefore, they can be a rough estimate of the severity of a health problem.

Bayer said that only a few of lawsuits involving Essure have been there. However, at least one female who got badly affected with the device came up with a Facebook page and was responded by thousands of people.

It has been estimated by the company that since 2002, nearly 750,000 Essure devices have been implanted and most of these implants have been done in the US.

As per Dr. Patricia Carney, medical director/women's health at Bayer, "We also want to know what's going on. We, too, are seeing these [adverse] events, but the benefits outweigh the risks". According to Bayer officials, the company has been keeping an eye on social media reports in relation to reactions to Essure.
