More and more men are turning to cosmetic procedures like penile fillers to increase the size of their penis. These fillers often contain hyaluronic acid, a substance naturally found in the body that helps retain water in tissues. This property is why hyaluronic acid is commonly used in facial fillers to smooth wrinkles. When injected into the penis, it can temporarily increase girth. A study from Korea reported an average increase of 2.3 cm in flaccid girth, or about 30%. However, more than half of the participants required additional injections to correct uneven areas. The effects of hyaluronic acid fillers are not permanent. The body produces an enzyme called hyaluronidase that gradually breaks down the filler over time. By 18 months, about 44% of the initial increase is lost, requiring repeat treatments to maintain results. If complications arise, hyaluronidase can be injected to reverse the effects, though it takes several hours to work. Despite the popularity of these treatments, the risks are not fully understood. A recent study estimated that about 9% of men who receive penile fillers experience complications. These can range from bruising and swelling to more serious issues like tissue breakdown, infections, and even the need for partial removal of the penis in extreme cases. Some complications can occur months or even years after the injection. Tragically, in March, a social media influencer named Igho Ubiribo, known as "Ego," died from a pulmonary embolism after undergoing a penile filler procedure in Thailand. Other methods for increasing penis size include fat grafting, where fat is taken from another part of the body and injected into the penis. This method carries its own risks, including uneven fat distribution, swelling, bruising, and the potential for infection. In severe cases, fat embolism can be life-threatening. Another treatment gaining attention is PRP, or platelet-rich plasma, which involves drawing blood from the patient, spinning it to isolate the platelet-rich portion, and then injecting it into the target area. While PRP is not intended to increase penis size, it is marketed to improve appearance, blood flow, and nerve function. However, the evidence supporting these claims is limited, and medical associations caution that more research is needed before these treatments can be widely recommended.
