Penis fat transfer, also known as penile fat injection or autologous fat transfer to the penis, is a procedure designed to increase the girth of the penis by transferring fat from another part of the patient's body. The procedure typically begins with liposuction, where fat is harvested from areas such as the abdomen, flanks, or thighs. The collected fat is then purified and processed to isolate viable fat cells and remove impurities. Once the fat has been adequately prepared, it is carefully and strategically injected into the penile shaft using a series of small, fine needles. The aim is to achieve a uniform increase in penile circumference without affecting the erectile function.

The procedure itself typically takes a few hours and is usually performed under local anesthesia with sedation, although general anesthesia can also be an option. Post-operatively, patients are advised to follow specific aftercare instructions which may include wearing loose-fitting clothing and avoiding strenuous activities for a few weeks to ensure proper healing and fat integration. Some swelling or bruising is common in the initial recovery period. The results of the fat transfer are generally visible immediately, though some of the transferred fat may be reabsorbed by the body over time. In some cases, a secondary procedure may be recommended to achieve the desired results. Regular follow-up appointments are essential to monitor the progress and ensure the best possible outcome.
