What can go wrong
Surgical repair carries risks of urethrocutaneous fistula, meatal stenosis, urethral stricture, diverticulum, residual curvature, and need for reoperation, with higher complication rates in proximal and reoperative cases. Untreated significant hypospadias can impair directed voiding, sexual function, and fertility (with very proximal openings). Care should be delivered by experienced pediatric/reconstructive urologists with long-term follow-up into adulthood.
This is something to take to a clinician. The Atlas can tell you what is known about hypospadias & epispadias in general. It cannot tell you what is happening in your body, and the difference matters most for exactly the symptoms that bring people to this page.
Hypospadias is a common congenital anomaly in which the urethral meatus opens on the ventral (underside) surface of the penis rather than at the tip, often with a hooded foreskin and sometimes ventral curvature (chordee). Severity ranges from a mildly displaced glanular/coronal meatus to penoscrotal or perineal openings. Epispadias is the much rarer dorsal variant, in which the meatus opens on the top surface, and can occur as part of the bladder exstrophy-epispadias complex. Treatment is surgical reconstruction (urethroplasty with curvature correction), typically performed in infancy or early childhood, to create a straight penis with a terminal meatus and a functional, cosmetically acceptable result.
The urethra opening in the wrong place, on the underside in hypospadias, on the top in the rarer epispadias.
What people take it for
What it is taken for. Approval, where it exists, covers only some of these.
- Surgical reconstruction of hypospadias
- Standard treatment, generally in infancy or early childhood; technique depends on meatal position and curvature severity, with distal cases often single-stage and proximal cases sometimes staged.
- Correction of chordee (orthoplasty)
- Performed at repair to straighten ventral or dorsal curvature so the erect penis is functional.
- Epispadias / exstrophy-complex reconstruction
- More complex; addresses dorsal urethra, curvature, and, in the exstrophy complex, the bladder and pelvic anatomy, often in staged procedures at specialized centers.
- Deferring circumcision
- Recommended when hypospadias is identified, because foreskin tissue is often used in the repair.
How it works
Surgical repair reconstructs the urethra (urethroplasty), straightens any curvature (orthoplasty), and reconstructs the glans and skin to position a functional terminal meatus and create an acceptable cosmetic and functional result. Many distal hypospadias repairs use techniques such as tubularized incised plate (TIP/Snodgrass) urethroplasty; more proximal or severe cases may require staged repairs and grafts or flaps. Circumcision is typically deferred because the foreskin may be needed for reconstruction.
In hypospadias, incomplete fusion of the urethral folds during fetal development leaves the meatus on the ventral shaft; associated features include a dorsally hooded prepuce (incomplete ventral foreskin) and, in more severe cases, ventral chordee from a tethering urethral plate or dysgenetic tissue. In epispadias, the urethral plate forms on the dorsal aspect, with dorsal chordee; the most severe form is part of the bladder exstrophy-epispadias complex, which also involves the bladder and pelvic ring.
Safety in detail
Hypospadias and epispadias are congenital conditions requiring evaluation and surgical reconstruction by experienced pediatric or reconstructive urologists. Repair carries documented risks including fistula, stricture, and need for reoperation. Circumcision should be deferred until a specialist evaluates the anatomy.
What people get wrong
Often saidHypospadias is caused by something the parents did
ActuallyHypospadias results from incomplete fetal urethral development with multifactorial genetic and hormonal contributions; it is not caused by parental behavior.
Often saidRepaired hypospadias means no sexual function
ActuallyMost men have functional erections, voiding, and fertility after successful repair, though some need revision and a minority have residual cosmetic or curvature concerns.
Often saidA boy with hypospadias should be circumcised at birth like any other
ActuallyCircumcision is generally deferred when hypospadias is found, because the foreskin is often needed for reconstruction.
Who profits, and who pushes back
Nobody is named here yet, because we have not done that work on this entry. Read that as unfinished. Somebody almost certainly sells this, and somebody almost certainly disputes it. Assume both until we have checked.
How we got here
Hypospadias has been recognized since antiquity, with descriptions attributed to the Alexandrian and Greco-Roman physicians; surgical attempts at repair were described over centuries with poor early results. Reliable reconstruction emerged in the twentieth century as anesthesia, magnification, fine sutures, and pediatric urological technique advanced, and the field continues to refine single-stage and staged repairs and the timing of surgery.

The studies that matter
Pediatric urology series on hypospadias repair outcomesvarious
Modern techniques such as tubularized incised plate urethroplasty achieve high functional and cosmetic success in distal hypospadias; proximal and reoperative cases have higher complication rates including fistula, stricture, and meatal stenosis.
Long-term follow-up after hypospadias repairvarious
Most men have functional voiding and sexual function after repair; some report residual cosmetic concerns, occasional curvature, or need for revision, supporting long-term follow-up into adulthood.
