Estrogen, progesterone, and testosterone: can they be used to treat autoimmune diseases?
Level 5 - mechanism / opinion, no new human data
Narrative review without systematic methodology
PubMed 7923746 · doi:10.3949/ccjm.61.4.276
What was done
This narrative review synthesized literature on the immunomodulatory actions of sex hormones (estrogen, progesterone, testosterone, and prolactin), their roles in autoimmune pathogenesis, and their potential therapeutic use, focusing primarily on rheumatoid arthritis and systemic lupus erythematosus.
What was found
No quantitative data or effect sizes are reported in the abstract. Qualitatively, progesterone and androgens suppress immune function, prolactin stimulates it, and estrogens have variable effects. Rheumatoid arthritis generally improves during pregnancy, estrogen replacement therapy, and oral contraceptive use, though direct estrogen treatment showed limited promise while testosterone replacement in men showed modest benefit. Systemic lupus erythematosus is aggravated by pregnancy and estrogens; 19-nortestosterone showed little benefit, danazol helped some patients, and dehydroepiandrosterone showed preliminary positive results.
Why it matters
It emphasizes the opposing immunomodulatory roles of sex hormones across distinct autoimmune conditions, highlighting why therapeutic hormone strategies differ between rheumatoid arthritis and systemic lupus erythematosus.
Limits
The abstract provides no quantitative metrics, sample sizes, or formal literature selection criteria. As a narrative review from 1994, it reflects historical practice and preliminary observations rather than systematic evidence synthesis.

- context Excessively high estradiol levels can disrupt thyroid binding sites, impair cortisol signaling, and stimulate autoimmune disease, while progesterone protects against autoimmune disease.
