Molar Pregnancy
In other cases, a chromosomal abnormality may lead to a rare condition called a molar pregnancy. During a molar pregnancy, tissues that were meant to form into a fetus instead become an abnormal growth on the uterus. There are two types of molar pregnancy:17
Complete molar pregnancy: A complete molar pregnancy is caused when the egg has no genetic information and is fertilized by one or two sperm. Due to the lack of genetic information from the mother’s side, the fertilized egg develops a placenta that looks like a cluster of grapes without an accompanying fetus.
Partial molar pregnancy: A partial molar pregnancy occurs when an egg with genetic material is fertilized by two sperm. It causes the development of an embryo that has multiple copies of chromosomes, forms some abnormal placental tissue, and usually does not survive.
