| Classification | Approximate relative frequency (%) | Ectopic urethral location | Penile curvature¶ | Foreskin appearance | Management |
| Forme fruste of hypospadias (incomplete or partial presence of hypospadias) | 10 | Normal location with a urethral pit or ectopic urethra on the distal glans | Normal | Normal to mild asymmetric ventral deficiency (incomplete closure around the glans) | - No surgical correction or further evaluation needed
|
| Standard hypospadias with normal glans width (maximal diameter ≥14 mm) | 40 | Distal urethral location on glans or coronal margin | Normal to mild | Ventral deficiency with a dorsal hooded appearance | - Surgical correction in most cases, however, families may choose observation
- No other evaluation
|
| 25 | Proximal urethral location on penile shaft, at the penoscrotal junction, or within the scrotum | Moderate | Ventral deficiency with a dorsal hooded appearance | - Surgical correction required
- No other evaluation
|
| Severe with an abnormally small glans (maximal diameter <14 mm) | 20 | Scrotum or perineum with an abnormally small glans (maximal diameter <14 mm) | Severe | Ventral penile foreskin tethering (referred to as short urethral plate) or fusion of the foreskin to the scrotum | - Surgical correction required (usually two-stage procedure)*
- Endocrine evaluation to detect disorders of sex development*
|
| Other variants | 5 | |
| Chordee without hypospadias | | Normal urethral opening and glans | Mild to severe | Normal | - Surgical correction of chordee
- No other evaluation
|
| Megameatus intact prepuce | | Large urethral opening at the coronal margin | Normal | Normal | - Correction is usually performed based on family preference
- No other evaluation
