Traditionally one of the most common procedures to enhance the thickness of the penis is the injection of fat (free fat transfer).  The fat injected is usually harvested from other parts of the body (liposuction). A proportion of injected fat is being absorbed over time and the results of a free fat transfer remain somewhat variable. An alternative is the use of hyaluronic acid injections into the penis. Hyaluronic acid is widely used as filler in aesthetic medicine. The treatment does not require general anesthesia, only takes minutes and there is no downtime as with surgery. The penis is instantly thicker and the effect usually lasts for about 12-24 months. Repeat treatment will be possible.In cases where an increase in the size of the penile tip (glans penis) is required, hyaluronic acid gel injections can be used safely and effectively.

Permanent grafts (either harvested as dermal fat grafts from other parts of the body or commercially available biological matrix) can be used to enhance penile girth. The penile skin will be pulled back and the graft material will be wrapped around the penile shaft and secured with absorbable sutures.Surgical procedures to enhance penile girth can be carried out on their own or ideally in combination with an operation to lengthen the penis.
