Penis enlargement

1. 01

   Assessment before consent

   Flaccid and stretched length, flaccid and erect circumference are documented with standardised photography, and a validated instrument such as the COPS-P scale screens for penile dysmorphic disorder. This stage decides whether we operate at all — men whose measurements are normal and whose distress is dysmorphic tend to be worse off after surgery, not better.

2. 02

   Anaesthesia and donor harvest

   Under general or spinal anaesthesia, fat is taken from the lower abdomen or flank at low negative pressure through small-bore cannulae. Suction pressure and cannula size are not trivia: adipocytes sheared at harvest are dead before they are ever injected, and no later technique recovers them.

3. 03

   Processing the lipoaspirate

   The harvested fat is washed, decanted, centrifuged or filtered through a closed membrane to strip out blood, oil, lysed cells and residual local anaesthetic. Only concentrated viable fat is worth injecting — the fluid fraction adds girth on the operating table that is gone within weeks.

4. 04

   Grafting the subdartos plane

   Through small access incisions at the penopubic junction or coronal sulcus, the fat is laid down in small aliquots through a blunt cannula and moulded circumferentially along the shaft; reported volumes run 40–80 mL. Deposition stays superficial to Buck’s fascia, so the neurovascular bundle, the tunica albuginea and the erectile bodies are never entered — which is why erections, sensation and urination are unchanged. We stop deliberately short of the girth you asked for rather than overfilling, because fat packed beyond the reach of a blood supply becomes necrosis and palpable nodules.

5. 05

   One inpatient night, then discharge

   A light compressive dressing goes on the shaft and a compression garment on the donor site, and you stay one night on the ward. You leave the following day with a wound check booked for day 2–3, because the access incisions and the donor site are where an early infection declares itself.

1. Day 1

   The shaft is bulky, swollen and bruised under a light compressive dressing, and the donor site at your abdomen or flank is sore under a garment. A urinary catheter is not routine. Oral painkillers are usually enough, and erections are uncomfortable but not dangerous to the graft at this stage.

2. Week 1

   Dressings come down and we inspect the small access incisions. Swelling and bruising peak in the first few days and then begin to settle — the shaft still looks considerably larger than the eventual result, and we will ask you not to judge it yet. Most desk-based work resumes in this window; the graft is still building a blood supply, so no pressure, no traction devices, no cycling and no sexual activity.

3. Weeks 2–4

   Walking and desk work are fine; the gym is not. Hold off on running, cycling, core and lower-body training and anything that presses on the shaft until around week 6 — shear and pressure on fat that is still revascularising is what turns graft into necrosis and nodules. The donor-site garment stays on essentially full time through the first month, and as swelling falls away the shaft looks smaller than it did on day 7; that is the graft settling, not failing.

4. Week 6

   Sexual activity and masturbation are generally permitted around now — Cleveland Clinic patient education notes the wait for the more invasive penile procedures may be as long as 6 weeks. Swelling has largely resolved, so this is the first honest assessment of contour, symmetry and any lumps you can feel. Early nodules are either softening or declaring themselves as fat necrosis.

5. Month 6

   The bulk of resorption has happened. Published series show measurable fat loss by 6 months, with a positive correlation between the volume injected and the girth retained. The circumference measured now approximates the durable result, and this is the earliest reasonable point to discuss a second grafting session.

6. Month 12

   The settled endpoint in the published series. In the 355-case cohort, resting circumference at 12 months was 11.06 cm against a pre-operative 8.3 cm, slightly below the 11.5 cm recorded at 2 months. Residual nodules or contour irregularity still present at a year are unlikely to resolve without revision surgery.

Every operation carries risk. We name them so you can ask the right questions.

• Graft resorption and volume loss — retention is unpredictable, greater than 30% fat loss was recorded in 5.9% of patients in a 355-case series, and repeat grafting is frequently required to maintain girth
• Palpable fat nodules, oil cysts and fat necrosis — irregular residual nodules are among the most commonly reported adverse outcomes, and inflammatory nodules may need surgical excision
• Contour irregularity, asymmetry, shaft deformity and scarring — including asymmetric fat hypertrophy and atrophy, penile skin deformity and scrotalisation of shaft skin, sometimes requiring staged reconstruction
• Infection, hematoma and wound complications — reported organisms include Staphylococcus aureus and Escherichia coli, a 355-case series reported long-standing hematoma in 1.1%, and referral-centre series describe wound complications and reoperations
• Sexual dysfunction and penile fibrosis — transient reduction in erectile function was reported in 0.8% of one large series, and referral-centre and review data describe penile fibrosis, painful erection, altered sensation and sexual dysfunction after augmentation procedures
• Fat embolism — rare but catastrophic; a fatal case has been reported in a 30-year-old man after injection of 70 mL of autologous fat
