Whether the treatment of male penis enlargement is credible or not should be taken into account in the specific case. If it is a formal hospital that takes penis lengthening and thickening or penis reconstruction, it is credible. If it is an informal treatment program provided by an informal hospital, it is generally not credible. The effect of penis enlargement varies individually according to the individual’s physique, post-operative care, medical institutions and physician’s skill level. Generally speaking, after penis enlargement surgery has normal erection and sensation function, the enlargement effect is better, which can improve the quality of sexual life of couples. However, postoperative complications such as penile edema, flap tip necrosis, and subcutaneous hematoma may occur. Penile lengthening surgery should be chosen according to men’s physiological characteristics and the need to lengthen the penis. It is recommended to consult and treat in regular hospitals.
