Penis enlargement and thickening methods include hormone supplementation, surgical treatment and other methods, and different methods are adapted to different groups of people. 1. Hormone supplementation: some underage patients with short penis and developmental disorders are mostly caused by small testicles or insufficient secretion of androgen. Such patients can undergo androgen test, and if it is found that it is really due to the above reasons, androgen supplementation, such as testosterone undecanoate and so on, can be used to promote the development of testicles and penis. For children with abnormal pituitary function, human chorionic gonadotropin can be used. For children with abnormal hypothalamic function, luteinizing hormone releasing hormone can be applied. All of the above drugs need to pay attention to the side effects and adverse reactions of the drugs, please use the above drugs under the guidance of a doctor. 2. Surgery: For adult patients, the penis has basically fully developed, generally will not continue to grow, drug treatment is usually ineffective, so can only be changed through surgical methods, such as penis lengthening and thickening surgery, penile reconstruction, and other methods, but there is a certain degree of risk of surgery, you should be fully aware of the pros and cons of the surgery, choose carefully.
