One of the causes of early miscarriage is a blighted ovum. This is a phenomenon where the egg has been fertilized but does not develop and there is no embryo. At this time, there is only a gestational sac in the uterus, and the embryo will not be able to attach and develop.

No embryo, also known as blighted ovum, is a condition in which a fertilized egg travels to the uterus but fails to develop into an embryo. This condition is usually caused by chromosomal abnormalities in the wife, the husband, or both spouses.

The ovaries are one of the reproductive organs of women. Each woman has two ovaries, located in the pelvis and are about the size of a walnut. If the ovaries are abnormal, such as anovulatory ovaries, it will directly affect the conception process.
