Men who are unable to grow their penises through exercise even after reaching adulthood and have a short penis can consider surgery as a way to deal with the problem. For men who have already reached adulthood, the sex organs have already fully developed and matured, and do not have the possibility of secondary development. Neither self-exercise nor medication will help the penis to grow again. Moreover, unscientific exercise or random application of drugs may cause damage to the reproductive system and affect reproductive health. Adult men with short penises that affect their normal sex life can consider penis lengthening or penis enlargement surgery. It should be noted that these surgeries have certain risks and are limited in increasing the size of the penis, so they should be diagnosed by a doctor and treated under the guidance of a doctor.
