Males with Sjogren's
The male-to-female ratio of Sjogren’s syndrome is 1:9. It is hard to find many other statistics about men or boys with Sjogren's. As with most other autoimmune diseases there is a low ratio of men and no definitive answer on why.

I suspect that many men are not getting a diagnosis of Sjogren's as they are not going to the doctor with their symptoms and if they are many doctors are not considering it as a condition to test for.
