🧬 Medical Principles & Scientific Mechanisms
Deep understanding of the physiological and pathological mechanisms of dysmenorrhea, mastering the scientific foundation of treatment principles

Key Anatomical Structures
Uterus
The primary site of dysmenorrhea, composed of muscular and endometrial layers. Muscular contractions are the direct cause of pain.
Endometrium
The tissue that sheds during the menstrual cycle, and the main production site of prostaglandins.
Ovaries
The control center for hormone secretion, regulating the entire menstrual cycle and pain occurrence.
🧬 Prostaglandin Mechanism
⚡ Physiological Effects:
PGF2α stimulates strong uterine smooth muscle contractions, with intensity exceeding labor contractions
Causes reduced uterine blood flow, leading to local ischemia and metabolite accumulation
Activates pain nerve fibers, lowering pain threshold
Promotes inflammatory mediator release, worsening pain and discomfort
⚖️ Hormonal Regulation Mechanism
Estrogen
- • Promotes endometrial thickening
- • Increases uterine muscle sensitivity to prostaglandins
- • Peaks before ovulation
Progesterone
- • Inhibits uterine muscle contractions
- • Stabilizes endometrium
- • Drops sharply before menstruation
Feedback Regulation
- • Hypothalamic-pituitary-ovarian axis
- • GnRH pulsatile secretion
- • FSH/LH cyclical changes
- • Negative feedback regulation mechanism
Balance point: Hormonal imbalance is the root cause of dysmenorrhea
🧠 Neural Conduction Mechanism
Pain Conduction Pathway
Pain Control Mechanism
Gate Control Theory
Large fiber activation can inhibit pain signals, which is the physiological basis for massage and heat therapy effectiveness
Endogenous Analgesia
Release of endogenous opioids like endorphins and enkephalins provides natural pain relief
Descending Control
Brainstem nuclei regulate spinal pain conduction
💊 Scientific Mechanisms of Treatment Methods
NSAIDs
Mechanism: Inhibits COX enzyme activity
Effect: Reduces prostaglandin synthesis
Representative Drugs: Ibuprofen, Naproxen
Best Timing: Use before pain starts
Efficacy: Can reduce pain by 70-80%
Heat Therapy
Mechanism: Activates heat receptors
Effect: Gate control, vasodilation
Temperature: 40-45°C optimal
Duration: 15-20 minutes per session
Synergy: Synergistic effect with NSAIDs
Hormonal Therapy
Mechanism: Inhibits ovulation
Effect: Stabilizes hormone levels
Type: Combined oral contraceptives
Applicable: Severe primary dysmenorrhea
Efficacy: 90% of patients show symptom improvement
Exercise Therapy
Mechanism: Releases endorphins
Effect: Improves blood circulation
Type: Aerobic exercise, yoga
Intensity: Moderate intensity optimal
Long-term: Requires 6-8 weeks of continuous practice to see results
🔬 Latest Research Progress
🧬 Molecular Target Research
Development of new drugs targeting key molecules like COX-2 and prostaglandin receptors, improving treatment efficacy while reducing side effects
🤖 Artificial Intelligence Applications
Using machine learning algorithms to analyze dysmenorrhea patterns, providing personalized treatment plans and predictive models
🧬 Gene Therapy Prospects
Gene Polymorphism Research
Research shows that COX-2 gene polymorphisms are related to dysmenorrhea severity, potentially enabling genotype-based personalized treatment in the future
Epigenetic Mechanisms
The role of DNA methylation and histone modifications in dysmenorrhea occurrence is being intensively studied, providing clues for new therapeutic targets
📊 Clinical Evidence-Based Evidence
