There’s good news for those with multiple sclerosis (MS). A new study has found that female participants were no more likely to have a flare-up of the disease after receiving fertility treatments than they were before their treatments. The study is published in the March 15, 2023, online issue of Neurology Neuroimmunology & Neuroinflammation. Earlier studies had shown conflicting results. The study also found a link between the use of MS medications and a lack of increase in relapses during fertility treatments.
