10 Causes of Stuttering
Cause #2: Family History
When a mother’s eggs are fertilized by the sperm, the sperm shares its DNA with the egg. This, combined with the mother’s DNA, provides the blueprint to how we will develop and grow. It is the blueprint to how we will grow physically, and also determines a great deal about who we are mentally.
This DNA also contains information that is not so beneficial, such as the phenomena of stuttering. In many people, it has been passed down to them genetically by at least one of their parents. If you know somebody that has a stutter, there’s a good chance that one of their parents also stutters.
