Multiple studies and reviews demonstrate that sex hormones and hormonal fluctuations significantly influence the pathogenesis, severity, and progression of rheumatoid arthritis.
The retrieved papers consistently support the claim that hormonal fluctuations and sex hormones play a key role in the pathogenesis and progression of rheumatoid arthritis. Papers [1], [2], [4], [5], [7], and [8] all link sex hormones, endocrine variations, and life-stage hormonal shifts (such as pregnancy and menopause) to immune dysregulation and the severity or progression of RA. There are no papers refuting the claim.
