No, a blighted ovum cannot turn into a molar pregnancy. Blighted ovum and molar pregnancy are obviously not the same thing. And they can not derive one from the other. A blighted ovum is when the egg manages to implant itself but fails to grow into an embryo. The gestational sac and placenta will grow as they should, but the embryo won’t grow so the gestational sac stays empty. Whereas molar pregnancy is when the egg to be fertilized has a problem itself. This disrupts the growth of the baby and the placenta. They don’t develop the way they should after conception. Molar pregnancies are pretty rare, and they usually don’t survive.
Why can’t a blighted ovum turn into a molar pregnancy?
Where a blighted ovum is caused by the failure of a fertilized egg to implant itself in the uterus lining, a molar pregnancy occurs when a fertilized egg develops into separate structures without any signs of a fetus.
A blighted ovum is a term used to describe a situation whereby a fertilized egg successfully implants it on the uterus only to fail to implant and develop into an embryo. It fails to form an embryo but only presents with the gestational sac, which is common in cases where chromosomal abnormalities are present.
A molar pregnancy is a condition that occurs when there is an aberrant formation of the egg. In a complete molar pregnancy, a vacant shell of an egg is filled by sperm giving rise to tissue containing no development of normal fetus tissue but rather a tumor of malignant cells.
For a partial molar pregnancy, it is characterized by the presence of both normal and abnormal cells in the pregnancy, but the fetus cannot survive. As such, the one condition does not change into another because they have different pathways and processes.
