Study reveals reason women are more sensitive to pain than men

October 25, 2005

ARLINGTON HEIGHTS, Ill. - For centuries, it has been generally believed women are the more sensitive gender. A new study says that, when it comes to pain, women are in fact more sensitive. According to a report published in October's Plastic and Reconstructive Surgery®, the official medical journal of the American Society of Plastic Surgeons (ASPS), women have more nerve receptors, which cause them to feel pain more intensely than men.

"This study has serious implications about how we treat women after surgery as well as women who experience chronic pain," said Bradon Wilhelmi, MD, ASPS member and author of the study. "Because women have more nerve receptors, they may experience pain more powerfully than men, requiring different surgical techniques, treatments or medicine dosages to help manage their pain and make them feel comfortable."

According to the study, women averaged 34 nerve fibers per square centimeter of facial skin while men only averaged 17 nerve fibers. Despite psychosocial expectations for men to be tougher than women when feeling pain, these findings illustrate that women's lower pain tolerance and threshold are physical.

"Eighty-seven percent of the 9.2 million cosmetic surgery procedures performed last year were on women," said Dr. Wilhelmi. "The ability to minimize pain often affects a patient's perception of their results. We hope this data will give new perspective on how to better treat post-operative pain in women."

Currently, 15 to 20 percent of the U.S. population suffers from acute pain, says Dr. Wilhelmi, while 25 to 30 percent suffer from chronic pain.

	Pain by Patrick Wall (Author) AAUP Excellence in Interior Design; New York Book Show Excellence in Cover Design Pain is one of medicine´s greatest mysteries. When farmer John Mitson caught his hand in a baler, he cut off his trapped hand and carried it to a neighbor. "Sheer survival and logic" was how he described it. "And strangely, I didn´t feel any pain." How can this be? We´re taught that pain is a warning message to be heeded at all costs, yet it can switch off in the most agonizing circumstances or switch on for no apparent reason. Many scientists, philosophers, and laypeople imagine pain to operate like a rigid, simple signaling system, as if a particular injury generates a fixed amount of pain that simply gets transmitted to the brain; yet this mechanistic model is woefully lacking in the face of the...
