A 12-year-old boy has a concern about his small penis, which is much smaller than his peers. His foreskin cannot be retracted, and the glans is mostly covered. He saw only a tiny foreskin, less than one millimeter, when he was around 10 years old, and it was no more than two millimeters when erect. As he starts to develop, he worries about his future growth. He seeks advice on how to promote natural growth and possible solutions, including dietary therapy or supplements. Thank you in advance for any help.
