Women who have multiple sclerosis experience normal pregnancies. In fact, women who have MS who are pregnant experience fewer relapses and less severe disease symptoms during the course of their pregnancy and breastfeeding. Once the mother stops breastfeeding, usually her symptoms return.

Previously, this was attributed only to a natural suppression of the female immune system while she is with child (essentially a foreign tissue within her body). However, a recent animal study has shown that prolactin (the enzyme which causes lactation) actually causes the body to repair myelin. This link between prolactin and natural myelin restoration is being investigated.
