Non-Surgical vs Surgical Penis Enlargement

Androfill is a non-surgical alternative to penoplasty using hyaluronic-acid filler. Here are the pros and cons of each approach — with the evidence.

Length surgery

Cutting the suspensory ligament.

The most common length surgery involves cutting the ligament that attaches the penis to the pubic bone and performing a skin graft at the base to allow extra length. This adds length to the flaccid penis only — there is no change to the size of the erect penis, and because the ligament no longer offers support, the erection points at a lower angle.

"The advantage of a 2 cm gain in flaccid length is far outweighed by the loss of angle of erection … A lot of men who have this treatment don't truly appreciate this loss of angle. It can make sex quite uncomfortable."Professor Kevan Wylie, cited by the UK NHS (2015)

Girth surgery

Fat injection and its limits.

Some surgical techniques increase girth by injecting fat taken from elsewhere in the body into the penis. Longer-term follow-up has shown disappointing results, with complications including disfigurement, scarring, lumpiness and infection.

"The problem with injecting fat is that over time, the body will re-absorb the fat, which can result in a return to the penis' original size."Professor Kevan Wylie, cited by the UK NHS (2015)

By contrast, a reversible dermal filler is placed non-surgically, has a firmer and more natural texture, and can be dissolved if you are ever unhappy with it. For girth, this makes surgery largely unnecessary today.

Weighing it up

The trade-offs.

Non-surgical filler

  • No cutting, minimal bleeding
  • ~30 minutes, walk in / walk out
  • Firm, realistic texture
  • Reversible — can be dissolved
  • Predictable, doctor-controlled volume
  • Top-ups maintain the result

Surgery

  • Incisions, general anaesthetic
  • Longer recovery
  • Length surgery: flaccid gain only, lost angle
  • Fat injection: reabsorption, lumps, scarring
  • Not reversible
  • Higher complication rate
