Once the penis has attained its adult size nothing can be done till date. Many research is going on but the
treatment with pills, surgeries, suction devices, exercise etc have not been satisfactory. They may on the
other hand cause stress, anxiety, infections etc. The normal length of penis in erect position is 5.1 to 5.9
inches. Any size below 2 inches is considered micro penis. You might consult a genitourinary specialist as
well. Hope it helps. Take care and keep posting.
