Can infertility result from a molar pregnancy?

Not usually. Molar pregnancies are abnormal pregnancies that act almost like cancers. They require treatment with a d & c, sometimes with chemotherapy and very rarely with hysterectomy. Because the marker for molar pregnancy is the same hormone, hcg, that makes + pregnancy tests, women are recommended to wait for about 6 months before getting pregnant again.
More details needed. Are you sure that you mean 'molar' pregnancy? I am not sure what you are asking. Can you please give more specifics?
