New Study Unveils Sex-Based Differences in Pain Receptors

Research reveals distinct nociceptors in males and females, paving the way for sex-specific pain treatments.

University of Arizona researchers identified functional differences in nociceptors between sexes.
The study found prolactin sensitizes nociceptors in females, while orexin B does so in males.
These findings suggest new precision medicine approaches for treating pain in men and women.
The research involved tissue samples from mice, nonhuman primates, and humans.
The discovery challenges the assumption that pain mechanisms are identical across sexes.
