Abstract

To examine the reproductive pattern of women with idiopathic inflammatory myopathy (IIM) compared to the general population. Population-based, nationwide registers were used to identify offspring of women with IIM and comparators. Women with IIM in general had similar reproductive patterns as the comparators, whereas in those diagnosed between 26 and 45 years of age, there was an overall trend for fewer children as well as a higher proportion of nulliparity and a lower fertility rate in women with dermatomyositis than their comparators. Reproductive attention should be paid to patients with IIM diagnosed during the childbearing period.
