Background: Endometriosis affects approximately 6%–10% of women of reproductive-aged. Pain is the common symptoms associated with endometriosis and manifests as dysmenorrhea, chronic pelvic pain, dyspareunia, and/or dyschezia, can be debilitating. Aims and Objectives: To find out the association between type and degree of pelvic pain with the Revised American Society for Reproductive Medicine classification system. Materials and Methods: Thirty women with endometriosis were studied in Department of Obstetrics and Gynaecology. Pain intensity was assessed by visual analogue scale (VAS) and a score of 1-3, 4-6 and ≥7 is classified as mild, moderate and severe pelvic pain. Disease was staged as per the American Society for Reproductive Medicine (ASRM) classification system in grade I to Grade IV and pain severity was compared. Results: Mean age of study cohort was 30 ±5.75 years. Majority of the women with endometriosis were in stage III (36.66%), stage IV (30%) and stage II (23.33%). Distribution of type of pain across the ASRM stages was insignificant (p >0.05). Distribution of visual analogue scale for pain with ASRM Staging was statistically significant (p=0.001). Conclusion: We did not find any association between type of pain and ASRM stages however severity of pain has a significant association with ASRM stages.
