Penile shortening syndrome is a common disease in men, and the causes include the following: 1. congenital factors such as hypogonadism, hypogonadism, disorders of sex hormone secretion, androgen insensitivity; 2. acquired diseases such as penile sclerosis, penile trauma, spinal cord injury and other causes of penile shortening; 3. some adult men, although their penis size falls within the lower limit of the normal range, are overly Concerned about the size of their penis, triggering anxiety, low self-esteem and fear, and even lead to erectile dysfunction and significantly reduce the quality of life, such patients can also be treated according to penile shortening. Some scholars have found that only about 55% of adult men are satisfied with the size of their penis. Patients with short penis are usually perceived as lacking in manhood and creativity, and they easily close themselves off, affecting their social and self-confidence, lacking a sense of security and safety, and potentially affecting their work mood and social status, significantly reducing their quality of life and sometimes even causing psychogenic erectile dysfunction. Does hormonal treatment for penile shortening work? For patients with small penis, it is important to try to understand the cause of its pathogenesis in order to treat it symptomatically. Try endocrine therapy before puberty, using growth hormone, gonadotropin or androgen therapy respectively, which often has some effect on small penis before puberty. If the penis does not develop even after correct treatment during puberty, further androgen treatment during adulthood is often ineffective. Is physiotherapy effective for penile shortening? The difference in penile length assessment before and after physical therapy is not significant and is still controversial. The use of negative compression narrowing device suction and penile cavernous vasoactive agent injection has been effective for small penis complicated by impotence. Since there is no muscle tissue in the penis, mechanical approaches such as vacuum and massage to enlarge the penis are not exact, temporary enlargement is only slightly more blood filling, and improper operation can also lead to subcutaneous bleeding or damage to the cavernous tissue, but can be considered as an adjunctive treatment after penile lengthening surgery.
