Immune signals and hormones may explain why women's pain lingers longer
New research combining mouse experiments with human vehicle‑crash data suggests that pain after injury lasts longer in women because monocytes produce less IL-10, a molecule that both reduces inflammation and directly dampens pain signals; testosterone boosts IL-10 production in male monocytes, helping men recover faster. This shifts the view of the immune system from solely driving pain to also helping resolve it, pointing to therapies that enhance the body's natural pain‑resolution pathways to prevent chronic pain.
