A penis study focusing on the correlation between size and self-esteem was called off — because of the enormous response.

Alicia Walker, a sociology professor at Missouri State University, cut the project short after making headlines with the unorthodox request for photo submissions of male genitalia, the Springfield News-Leader reported.

She blamed the “public reaction” for the decision to terminate the research into how penis size impacts factors such as personal relationships, sexual competence and condom usage.

“I made this decision voluntarily,” Walker said in a statement. “I continue to believe the relationship between penis size and self-esteem is an important site of scientific inquiry, but the public reaction to the project threatens the reliability of the survey responses. The reliability of the study as a whole has been compromised.”

Walker told The Post earlier this week that she received a few hundred penis pictures since June 18. She said the photos were for verifying that participants correctly measured their genitalia and then would be deleted.

Those submissions were never viewed and have since been destroyed, according to the Springfield News-Leader.

Walker said the study’s findings could have helped guys with “anxiety and unhappiness” because of their perceived size.

“We need to be talking about men’s body dysmorphia, and the way our society worships size and the way that worship impacts men,” Walker told The Post.
