Multiple sclerosis (MS) is the most common chronic autoimmune demyelinating disorder of the central nervous system (CNS) which preferentially involves young women in early child bearing age. Opposite to traditional view emphasized on discouraging female patients from enduring pregnancy, recent investigations showed that pregnancy-related physiological alterations, especially during the third trimester, reduce the annual relapse rate of multiple sclerosis up to 80% which is comparable with conventional disease modifying drugs.
