Reproductive issues and multiple sclerosis: 20 questions.

Multiple sclerosis (MS) is commonly diagnosed in young adults during their reproductive years. Consequently, concerns about family planning and MS management related to pregnancy and breastfeeding are often encountered in clinical practice. Pregnancy itself is not harmful for women with MS. However, disease-modifying therapies (DMTs) have implications for reproductive planning, including stopping treatment while trying to conceive and during pregnancy, as well as managing fetal risks. People with MS and their care team must engage in collaborative decision-making before, during, and after pregnancy. Based on the results of a consensus-building initiative, answers are provided to 20 frequently asked questions regarding the management of MS during pregnancy planning, pregnancy, and the postpartum period.
