Does methotrexate cause fertility issues after molar pregnancy?

No: Methotrexate causes the abnormal molar pregnancy cells to stop growing. It will not affect fertility. It is important to avoid getting pregnant while taking the medication and for a few months after therapy is completed. Your doctor should give you details.

Molar pregnancy: Methotrexate only rarely causes fertility issues. The fertility issues are probably more associated with the age of your eggs.
