I had always wondered about male vs female re: stuttering. Just looked into it: AI Overview According to most research, the male to female ratio for stuttering is significantly higher, with estimates suggesting that around 4 times more males stutter than females, meaning roughly 80% of people who stutter are male and 20% are female; ----- Seems to track with the great prevalence of males in this group. But why? AI Overview The higher prevalence of stuttering among males compared to females is largely attributed to a combination of genetic factors, with potential influences from prenatal hormone exposure (like testosterone), leading to a theory that males might be more susceptible to developing stuttering due to their biological makeup; however, the exact cause remains complex and not fully understood, with research suggesting that females may also have a higher natural recovery rate from stuttering compared to males.
