| ==Introduction==
| | #REDIRECT [[Genital Abnormality - Hypospadias]] |
| Hypospadias are the most common penis abnormality (1 in 300) and result from a failure of male urogenital folds to fuse in various regions. This in turn leads to resulting in a proximally displaced urethral meatus. The cause is unknown, but suggested to involve many factors either indivdually or in combination including: familial inheritance, low birth weight, assisted reproductive technology, advanced maternal age, paternal subfertility and endocrine-disrupting chemicals.<ref><pubmed>11713004</pubmed></ref> Infants with hypospadias should not undergo circumcision.

| ==Hypospadia Classification==
| |
| [[File:Hypospadia classifications.jpg|thumb|300px|Classification of Hypospadias]] | |
| The condition is classified by the general location of the relocated opening (meatus) and lack of fusion.
| |
| | |
| ===Anterior Hypospadia===
| |
| Meatus located on inferior surface of glans penis.
| |
| | |
| ===Coronal Hypospadia===
| |
| | |
| Meatus located in balanopenile furrow.
| |
| ===Distal Hypospadia===
| |
| | |
| Meatus located on distal third of shaft.
| |
| ===Penoscrotal Hypospadia===
| |
| Meatus located at base of shaft in front of scrotum.
| |
| | |
| ===Scrotal Hypospadia===
| |
| | |
| Meatus located on scrotum or between the genital swellings.
| |
| | |
| ===Perineal Hypospadia===
| |
| | |
| Meatus located behind scrotum or genital swellings.
| |
| | |
| ==Surgical Repair==
| |
| | |
| Depending on the class of hypospadias there are a number of different surgical repair techniques including: orthoplasty or penile straightening, urethroplasty, meatoplasty and glanuloplasty, scrotoplasty and skin coverage.
