==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 name="PMID11713004"><pubmed>11713004</pubmed></ref> Infants with hypospadias should not undergo circumcision.
 
==Some Recent Findings==
 
* '''Correction of Distal Penile Hypospadias'''<ref><pubmed>20548222</pubmed></ref> "The major aims of correction of hypospadias include construction of a neourethra, removal of the chordee, and reduction of the probability of postoperative fistulization. Here, we describe a new technique that can be easily used in cases with subcoronal distal penile hypospadias (even those with chordee) for the construction of the urethra using meatus-based transverse flaps."
 
==Hypospadia Classification==
[[File:Hypospadia classifications.jpg|thumb|400px|Classification of Hypospadias<ref name="PMID11713004" />]]
The condition is classified by the general location of the relocated opening (meatus) and lack of fusion.
 
===Anterior Hypospadia===
 
:'''A''' Meatus located on inferior surface of glans penis.
 
===Coronal Hypospadia===
 
:'''B''' Meatus located in balanopenile furrow.
 
===Distal Hypospadia===
 
:'''C''' Meatus located on distal third of shaft.
 
===Penoscrotal Hypospadia===
 
:'''D''' Meatus located at base of shaft in front of scrotum.
 
===Scrotal Hypospadia===
 
:'''E''' Meatus located on scrotum or between the genital swellings.
 
===Perineal Hypospadia===
 
:'''F''' 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.
 
==Related Genetic Conditions==
* Johanson-Blizzard syndrome<ref><pubmed>20556423</pubmed></ref> - hypospadias, failure to thrive, exocrine pancreatic deficiency, short stature and developmental delay, cutis aplasia on the scalp, aplasia of alae nasi, hypothyroidism, myxomatous mitral valve, and patent ductus arteriosus.
