The term dysgenesis is used to describe abnormal organ development during embryonic growth and development. As opposed to agenesis, which refers to the complete failure of an organ to develop, dysgenesis usually implies disordered development or malformation and in some cases represents the milder end of a spectrum of abnormalities. Dysplasia is a form of dysgenesis in adults that alters the size and shape of their cells that lead to abnormal development.[1] One of the most common forms of dysdenesis if within the gonads.

How Dysgenesis Occurs

Dysgenesis occurs during fetal development immediately after conception. One of the first organs that is affected is the brain, this is known as Cerebral Dysgenesis. Examples:
