Pregnancy in women with multiple sclerosis in France from 2010 to 2015: Incidence, outcomes, and exposure to disease-modifying therapies.

In this population-based study, we showed an increase of exposed pregnancies over time, beta-interferon and glatiramer acetate being the most used DMTs and associated with the highest probabilities of live birth. Interrupted exposed pregnancies may reflect undesired pregnancies or fear of an adverse outcome, while recent DMT stop probably reflects pregnancy planning.
