Higher Male Fertility Rate Seen With Inflammatory Arthritis

TOPLINE: 

Men with an inflammatory arthritis (IA) diagnosis are less likely to be childless than healthy comparators, according to an epidemiological study.

METHODS:

10,865 men in the Norwegian Arthritis Registry were compared with 54,325 men without IA, matched by age and location.In the arthritis group, 37% had rheumatoid arthritis, 33% had psoriatic arthritis, and 30% had spondyloarthritis.Researchers used childlessness and number of children as proxies for male fertility.

TAKEAWAY:

21% of men with IA were childless compared with 27% in the healthy cohort (P <.001 an average a man with ia had children whereas in the control group findings were consistent over time but most pronounced difference between groups was seen men diagnosed after year>IN PRACTICE:

The finding “is novel and generates new hypotheses regarding associations between fertility, inflammatory rheumatic diseases, and immune-modulating drugs,” the authors wrote.
