MS drugs and trying to conceive

Hello, We are newly diagnosed but hoping to start a family I’m just wondering if anyone has any advice / information on trying to conceive whilst on MS drugs? With regards to the male being on medication. There seems to be a lot of information for women (many say to avoid conception ) but what about men who are on them? In particular ponesimod & ocrevus Any thoughts much appreciated ! Feel extremely anxious about it all Many thanks in advance
