2024 Menstrual Pain Research Progress Report: Evidence-Based Medicine and Clinical Translation

Based on PubMed database, FDA approval information, and published studies from authoritative journals

📈 Research Status Overview

Menstrual pain affects 45-95% of reproductive-age women, with over 30% of adolescents experiencing severe dysmenorrhea, seriously impacting learning, work, and quality of life. This report integrates the latest peer-reviewed research and clinical trial data from 2024 to provide evidence-based medical guidance for American women.

1. Pathological Mechanism Research Progress

1.1 Deepened Understanding of Molecular Biological Mechanisms

Core Role of Prostaglandin Pathway

Research confirms that excessive secretion of prostaglandin F2α (PGF2α) and E2 is the primary pathological mechanism of primary dysmenorrhea. These inflammatory mediators cause:

• Strong uterine smooth muscle contractions
• Uterine vascular constriction, causing local ischemia
• Increased sensitivity of pain nerve endings

New Understanding of Inflammatory Cascade Reactions

Overexpression of cyclooxygenase-2 (COX-2) is a key link, explaining the effectiveness mechanism of NSAIDs for dysmenorrhea.

1.2 Central Nervous System Changes

Central Sensitization Mechanism

Functional magnetic resonance imaging studies show that dysmenorrhea patients exhibit central sensitization phenomena, with abnormal activity in the anterior cingulate cortex and insula. Key findings include:

• Weakened pain inhibition system function
• Overactivation of pain facilitation systems
• Cross-organ sensitization phenomena (dysmenorrhea patients show increased sensitivity to other visceral pain)

Long-term Effects of Brain Structural Changes

Research has found abnormal changes in gray matter volume in dysmenorrhea patients' brains, which may lead to impaired pain inhibition ability, suggesting that dysmenorrhea may increase the risk of developing chronic pain states.

1.3 Emerging Research Directions

Preliminary Exploration of the Gut-Brain-Uterus Axis

Although related research is still in early stages, preliminary evidence suggests that the gut microbiome may affect dysmenorrhea through the following mechanisms:

• Regulating systemic inflammatory responses
• Affecting the neuroendocrine system
• Producing metabolites that influence pain perception

2. Innovative Treatment Breakthroughs

2.1 New Drug Development Progress

HMI-115: First Prolactin Receptor Antagonist

HMI-115 developed by Hope Medicine achieved breakthrough progress in global Phase 2 trials, with studies of 142 endometriosis patients showing:

• 42% reduction in dysmenorrhea scores
• 50% reduction in non-menstrual pelvic pain
• No impact on normal menstrual cycles
• Received breakthrough therapy designation from China's NMPA

Approved Next-Generation Drugs

Orilissa (elagolix): FDA-approved first oral GnRH antagonist for treating moderate to severe endometriosis pain, with clinical trials involving 1,686 patients

2.2 Non-Pharmacological Treatment Progress

Transcutaneous Electrical Nerve Stimulation (TENS) Therapy

TENS relieves pain through two mechanisms: 1) conducting electrical pulses through large-diameter sensory fibers to increase pain threshold; 2) stimulating endorphin release. Clinical studies confirm its safety and effectiveness.

Evidence-Based Support for Heat Therapy

Local heat therapy has been proven to significantly reduce menstrual pain, with effects comparable to NSAIDs, through mechanisms including:

• Increasing pelvic blood circulation
• Inhibiting uterine contractions
• Stimulating endorphin and serotonin release

2.3 Personalized Medicine Directions

Gene Polymorphism-Guided Medication

Personalized treatment based on drug-metabolizing enzyme gene polymorphisms is under research, such as CYP2C9 gene variations affecting NSAIDs metabolism and effects.

Pain Phenotype Assessment

Using quantitative sensory testing (QST) to assess individual pain sensitivity, predict treatment responses, and develop personalized protocols.

3. Evidence-Based Prevention Strategies

3.1 Scientific Evidence for Nutritional Interventions

Magnesium Supplementation

Research supports the relieving effect of magnesium supplementation on dysmenorrhea:

• Recommended dosage: 200-400mg daily
• Mechanism: Reduces muscle spasms, regulates neuromuscular function
• Few side effects, good safety profile

Vitamin Supplements

Evidence-based nutritional supplements include:

• Vitamin B1: 100mg daily
• Vitamin E: Antioxidant effects
• Omega-3 fatty acids: Anti-inflammatory effects

3.2 Lifestyle Interventions

Exercise Therapy

Regular aerobic exercise provides the following benefits:

• Increases pain threshold
• Improves blood circulation
• Releases natural analgesic substances
• Improves overall health status

Stress Management

Psychological stress is related to dysmenorrhea severity, with effective stress management techniques including:

• Cognitive behavioral therapy
• Mindfulness meditation
• Relaxation techniques

3.3 Complementary and Alternative Medicine

Evidence-Based Evidence for Herbal Medicines

Systematic reviews support the effectiveness of certain herbal medicines:

• Ginger: Anti-inflammatory and analgesic effects
• Fennel: Antispasmodic effects
• Cinnamon: Menstrual cycle regulation

4. Digital Health Technology Applications

4.1 Mobile Health Platforms

Symptom Tracking Applications

Value of smartphone applications:

• Recording symptom patterns and severity
• Identifying trigger factors
• Monitoring treatment effects
• Providing personalized recommendations

4.2 Telemedicine Services

Accessibility Improvement

Especially for rural and medically underserved areas:

• Providing professional consultation
• Reducing healthcare barriers
• Continuous monitoring and follow-up

5. Future Research Directions

5.1 Precision Medicine Development

Multi-omics Integration Research

Future integration will include:

• Genomic characteristics
• Epigenetic markers
• Proteomic data
• Metabolomic features

5.2 Novel Therapeutic Targets
