In modern society, the lack of lasting hardness and small penis size can have a great impact on men’s marital life and social life. For example, men with small size, in addition to affecting the relationship between the two sides, often lack self-confidence and are ashamed to go to the toilet, swimming, hot springs, saunas, etc. with their colleagues for fear of being told the secret and becoming a laughing stock. For men with this problem, I strongly recommend that you bravely and actively seek an effective procedure to improve your confidence. Here I introduce a patented technology of decellularized allogeneic dermis, which is a new material for effective treatment of premature ejaculation and external genital shortening, and also compiled some related questions for you to answer: What is decellularized allogeneic dermis? The decellularized dermal matrix (ADM) is a dermal substitute obtained by removing the cellular components of the allogeneic dermis through special treatment. It was first developed by Livesey and produced by Lifecell, and its trade name is AlloDerm. Several years ago, it was approved by FDA for clinical use, and ADM biological patch has been widely used and developed in clinical practice, especially in plastic surgery, and it has largely replaced autologous dermal flaps, and is now more and more widely used in China. How does decellularized allogeneic dermis treat premature ejaculation? Decellularized allogeneic dermis is an emerging technology, which is covered with decellularized allogeneic dermis on the dorsal nerve of penis for forty-five days, the tissue regenerates to form new autologous soft tissue, which increases the thickness of soft tissue on the dorsal nerve and achieves the effect of isolating the dorsal nerve, thus reducing the sensitivity when rubbing during sexual life and prolonging the sexual life, which is like putting on an invisible thickened condom for the penis permanently, and its advantages are (1) The dorsal nerve is not cut off, and there is no damage to the dorsal nerve, only the isolation of the dorsal nerve through the decellularized allograft dermis. (2) The dorsal nerve isolation by decellularized allograft dermis can achieve the effect of thickening at the same time, one surgery, two effects. (3) It is easy for patients to accept, and the clinical effect is immediate. (4) It is safer than dorsal nerve dissection. Does this surgery affect the erectile function of the penis? The operation is performed under the deep side of the fascia and the superficial side of the white membrane, so there is no damage to the white membrane and cavernous structure, no problem of cavernous fibrosis and venous leakage, no damage to the normal erectile function, and no erectile dysfunction is seen in the follow-up. Is the transplant material safe? The biggest problem of allograft is rejection, and the main components of skin graft that cause rejection are epidermal cells, fibroblasts and endothelial cells in the dermis. The non-cellular components, extracellular matrix proteins and collagen (i.e. ADM), have no immune activity and remain permanently in the allogeneic host. Therefore, ADM is an allogeneic dermis that completely removes cellular components and type I and II cytocompatibility antigens and fully retains elastin, keratin sulfate, laminin, and collagen with very low immune activity and does not induce any rejection reaction. ADM bio patch mainly contains two surfaces, basement membrane and dermis. The dermis in the ADM patch can provide sufficient dermal tissue for the wound to reduce scar formation and contracture; the rich collagen bundles and elastic fibers in the dermis are neatly arranged to resist the production of granulation and scar tissue, and make it soft and elastic to retain the elasticity and touch of human skin. Two weeks after ADM is implanted under the skin, there is a mild lympho-histiocytic infiltration and neovascularization, a very mild inflammatory reaction, and the inflammatory reaction subsides in 4 weeks. The implant acquires a stable volume and becomes a permanent part of the body. In today’s society, men are given more pressure than women, from life and from work. In my clinic, it is common to see successful people with a successful career and a great deal of talk, who are hesitant to have surgery because they have difficulty satisfying their partners sexually. I would like to say to these compatriots, come out bravely, surgery is not complicated and not scary, find a new sky for yourself!
