What are the differences between complete and partial molar pregnancy?

A complete molar pregnancy occurs when a sperm fertilizes a "blank" egg, resulting in a pregnancy with no viable fetus. Instead, the pregnancy consists of an abnormal growth of placental tissue that develops into a mass of cysts. In contrast, a partial molar pregnancy occurs when two sperm fertilize a single egg, which results in a fetus that has severe abnormalities and cannot survive, as well as an abnormal growth of placental tissue. The main difference between the two is that a complete molar pregnancy has no fetus, whereas a partial molar pregnancy has a fetus but with severe abnormalities. Additionally, complete molar pregnancy is more rare than partial molar pregnancy.
