Phalloplasty & Metoidioplasty in Thailand

Phalloplasty and metoidioplasty are gender-affirming procedures used to create masculine genital anatomy.

Both can form part of a broader transmasculine surgical pathway, but they use very different techniques and have different advantages, limitations and recovery requirements.

These procedures require highly specialised reconstructive experience and detailed individual planning.

What is phalloplasty?

Phalloplasty creates a penis using tissue transferred from another part of the body.

Common donor areas can include:

• Forearm

• Thigh

• Other selected donor sites

The transferred tissue is shaped to create the phallus and connected to its new blood supply.

Depending on the treatment plan, urethral reconstruction and scrotoplasty may also be performed.

What is metoidioplasty?

Metoidioplasty uses existing genital tissue that has enlarged in response to testosterone.

The tissue is surgically released and reshaped to create a small phallus.

Potential advantages compared with phalloplasty can include:

• Use of existing sensitive tissue

• No large flap donor site

• Shorter and less complex reconstruction in some cases

The resulting size is generally smaller than with phalloplasty.

Urethral lengthening

Some patients want the ability to urinate while standing.

This may require urethral reconstruction or lengthening.

Urethral surgery can increase the complexity of treatment and carries risks including:

• Fistula

• Narrowing

• Urinary difficulty

• Need for revision surgery

Patients should discuss the importance of standing urination when selecting a surgical approach.

Scrotoplasty

Scrotoplasty creates a scrotum using existing tissue.

Testicular implants may be inserted either during the same stage or during a later procedure.

The exact sequence depends on surgeon preference, healing and the overall reconstruction plan.

Penile implants

Following phalloplasty, some patients later choose a penile prosthesis to provide rigidity for penetrative intercourse.

This is normally performed after the reconstructed tissue has fully healed.

Implant surgery adds additional cost and carries risks such as infection, mechanical problems and need for future replacement.

Why phalloplasty is often staged

Complex genital reconstruction is frequently divided into multiple operations.

Stages may include:

• Hysterectomy or removal of reproductive organs where desired

• Vaginal closure

• Urethral preparation or reconstruction

• Phalloplasty

• Glans reconstruction

• Scrotoplasty

• Testicular implants

• Penile prosthesis

Not every patient wants or requires every stage.

Donor-site considerations

Phalloplasty requires tissue from another area of the body.

The surgeon considers:

• Tissue thickness

• Blood vessels

• Hair growth

• Scarring

• Patient preference

• Previous injury or surgery

The donor site itself requires significant wound care and leaves a permanent scar.

Assessment before surgery

Evaluation may include:

• Medical history

• Hormone treatment

• Previous surgery

• Genital anatomy

• Donor-site examination

• Blood tests

• General health assessment

• Readiness documentation where required

• Discussion of fertility preservation

The patient and surgeon should also establish which functional goals are most important.

The procedure and hospital stay

Metoidioplasty and phalloplasty differ considerably in complexity.

Major phalloplasty stages may require an extended operation and approximately one to two weeks in hospital.

Careful monitoring of transferred tissue is particularly important during the early postoperative period.

Recovery

Recovery can be lengthy and should be considered as a multi-stage process rather than a single short episode.

Early care may involve:

• Catheters

• Wound care

• Donor-site care

• Restricted movement

• Monitoring of reconstructed tissue

• Follow-up examinations

Later surgical stages may occur only after sufficient healing.

Risks and considerations

Potential risks can include:

• Bleeding

• Infection

• Wound-healing problems

• Loss of transferred tissue

• Urethral fistula

• Urethral narrowing

• Urinary complications

• Scarring

• Implant complications

• Changes in sensation

• Need for revision surgery

Phalloplasty is among the more complex forms of gender-affirming reconstruction.

Phalloplasty and metoidioplasty costs in Thailand

Pricing depends heavily on which procedures and stages are required.

A broad indicative range for staged treatment is approximately US$12,000–30,000 or more.

The final cost can depend on:

• Phalloplasty or metoidioplasty

• Donor-site technique

• Urethral reconstruction

• Vaginal closure

• Glans reconstruction

• Scrotoplasty

• Testicular implants

• Penile prosthesis

• Number of hospital admissions

• Follow-up and revision procedures

Siam Medica can help request a staged treatment plan and detailed quotation after a specialist reviews the case.
