The most common cause of miscarriage, particularly in early pregnancy, is improper embryo development.
Chromosomal Abnormalities and Miscarriage
About half of early miscarriages occur because the embryo doesn't develop correctly. This is often due to an abnormal number of chromosomes. Chromosomes, found in every cell, contain the genes that guide development and function. When these chromosomes are abnormal, it can disrupt the normal development process, leading to miscarriage.
Understanding Chromosomes
- Chromosomes are structures within cells that contain DNA.
- They carry genetic information that determines a person's traits.
- Abnormalities in chromosome number or structure can lead to developmental problems.
Why Chromosomal Issues Happen
Chromosomal abnormalities leading to miscarriage often arise randomly during the fertilization process, as sperm and egg combine. These errors are usually not inherited from the parents.
Other Potential Causes of Miscarriage
While chromosomal abnormalities are the leading cause, other factors can also contribute to miscarriage, though they are typically less frequent in early pregnancy.
