Spondyloarthritis & psoriatic arthritis
Men with psoriatic arthritis, rheumatoid arthritis and axial spondylarthritis have more children and at an earlier age than matched controls: results from a nationwide cohort
Authors' conclusion
This large nationwide study revealed that men with PsA, RA and axSpA were less childless compared with the general population, a difference that occurred before the onset of the IJD.
