The Role of Interleukin-10 in Pain Perception
Research suggests a key difference in how men and women experience and recover from pain may be linked to levels of a molecule called interleukin-10 (IL-10). Scientists conducting studies on rodents observed significant variations between male and female subjects. “Female mice took longer to recover from pain and produced lower levels of a molecule that helps calm the electrical activity of sensory nerves responsible for pain,” explained one researcher.
Building on these findings, researchers then examined individuals who had experienced traumatic injuries, such as car accidents. The study revealed that while both men and women reported similar levels of pain immediately following the injury, pain diminished more quickly in men over a three-month period.
This difference in recovery appears to be tied to higher levels of the protein interleukin-10 (IL-10) found in men, which may inhibit the transmission of pain signals to the brain. Understanding these biological differences is crucial for developing more targeted pain management strategies.
Hormonal Influences on Pain Sensitivity
Harrison Linder, a pain management specialist, explained to Women’s Health that hormones too play a significant role in pain perception. “In women, estrogen and progesterone influence the perception of pain and can even increase sensitivity to pain during the menstrual cycle. Here’s why many women report worsening migraines, pelvic pain, or musculoskeletal pain at certain times of the month,” he said.
Linder also noted that testosterone, the primary hormone in men, may have a protective effect against pain transmission, potentially by promoting IL-10 production. This finding warrants further investigation to fully understand the interplay between hormones and pain pathways.

Shravani Durbhakula, another pain specialist, highlighted the potential role of genetics. “Studies have identified more genetic factors linked to pain in women, which could explain why chronic pain is more prevalent in them,” she told the magazine. These genetic predispositions, combined with hormonal differences, may contribute to the observed disparities in pain experience.
Both specialists emphasized the importance of open communication about pain and underscored that seeking treatment is essential. They also stressed that experiencing pain is not a sign of personal failure or weakness and that effective management options are available.
