Molar pregnancy or hydatidiform mole is a condition which results from non-viable pregnancy. It may result when a normal sperm fertilized an ovum that doesn't have genetic material or when two sperms fertilize a normal ovum. In such cases, a benign tumor develops in the uterus which may or may not include an embryo and a placenta. Although pregnancy appears normal in initial stages but when symptoms like bleeding or discharge from vagina along with excessive nausea and vomiting develop, it may have to be diagnosed and removed at the earliest to avoid serious complications.Q&A: Hydatidiform Molemicrosoftstart.msn.com Mole | Definition, Number, & Facts | Britannica
