Questionsconcerningtherelationship of MS withpregnancyandthepostpartumperiod, assistedreproductiontechnology, preand post-operativeproblemsandvaccinesarealsofrequentlyasked, andsome of theanswersarestillcontroversial. It is knownthat MS has noharmfuleffect on pregnancyorthefetus. The presence of MS is not an indicationtoterminatepregnancy, anddiseaseprogression is not foundto be relatedwithpregnancy.
