1. Women Experience More Pain — and Different Pain

Women have:

• Higher prevalence of chronic pain conditions (e.g., migraine, fibromyalgia, pelvic pain, irritable bowel syndrome)
• Greater pain sensitivity and longer pain duration
• More pain experiences linked to reproductive and hormonal life stages (menstruation, pregnancy, postpartum, perimenopause, menopause)

Pain in women is often multisystem, fluctuating, and hormonally influenced, which does not fit neatly into traditional biomedical pain models.

2. Biological Sex Differences Matter

The review highlights several biological contributors:

• Sex hormones (estrogen, progesterone, testosterone) influence pain perception, inflammation, immune activation, and nervous system signaling
• Differences in central nervous system processing, including pain modulation pathways
• Immune system differences — women mount stronger immune and inflammatory responses, which can amplify pain signaling

Yet, many pain studies historically:

• Excluded women
• Failed to track menstrual cycle or hormonal status
• Treated male physiology as the default model

3. Gender Bias in Pain Assessment and Care

A major emphasis of the paper is systemic bias:

• Women's pain is more likely to be described as emotional, exaggerated, or stress-related
• Women are more likely to receive sedatives or antidepressants rather than appropriate pain care
• Women often experience longer diagnostic delays, particularly for conditions like endometriosis, autoimmune pain experiences, and chronic pelvic pain

This bias contributes to mistrust, delayed care, and poorer outcomes.

4. Chronic Pain, Mental Health, and Quality of Life

The authors stress that pain in women is tightly linked to:

• Anxiety and depression
• Sleep disruption
• Cognitive burden ("brain fog")
• Reduced work capacity and caregiving strain

Importantly, the review pushes back against the idea that this makes pain "psychological." Instead, it emphasizes the bidirectional connections between neuroendocrine and immune systems that link pain and mental health — real biology, not a state of mind.

5. Life-Course Perspective Is Essential

Pain risk and expression change across:

• Puberty
• Pregnancy and postpartum
• Perimenopause and menopause
• Aging

The review highlights menopause as a critical but under-studied pain transition, where declining estrogen is associated with shifts in pain thresholds, joint comfort, connective tissue resilience, and nervous system regulation.

6. Call for Structural Change

The authors call for:

• Sex-specific and gender-aware pain research
• Better education of clinicians on women's pain biology
• Inclusion of hormonal status in pain assessment
• Multidisciplinary care models that integrate gynecology, neurology, endocrinology, and pain medicine

They position women's pain as a legitimate, biologically grounded clinical priority, not a secondary or subjective complaint.

In conclusion, what this review makes clear is that menopause is not a footnote in the pain conversation. It is a turning point. As hormones shift, the systems that once helped regulate inflammation, protect nerves, and soften pain responses change too. For many women, this is when aches become persistent, migraines intensify, pelvic discomfort appears, or old injuries start speaking up again. When these changes are brushed off as "just aging" or stress, women are left managing real biological experiences without real support. Understanding the role menopause plays is the first step toward better conversations with providers and care that respects what is actually happening inside the body.
