Many chronic pain conditions show clear differences between between men and women, such as reported pain intensities or treatment effects, with chronic pain conditions being generally more frequent in women. Yet, the underlying mechanisms causing these differences are poorly understood. Central sensitization (CS) is considered one important mechanism in pain patients which differs between female and male patients. The central hypothesis is that already in the healthy population CS processes are more pronounced in women than in men.
