Changes

'''Hypospadias''' is a common variation in fetal development of the [[penis]] in which the [[urethra]] does not open from its usual location in the head of the [[penis]]. It is the second-most common birth abnormality of the male reproductive system, affecting about one of every 250 males at birth.<ref name="Snodgrass">{{REFbook

}}</ref> Roughly 90% of cases are the less serious distal hypospadias, in which the urethral [[urethra]]l opening (the [[Urinary meatus|meatus]]) is on or near the head of the [[Glans penis|penis glans]]. The remainder have proximal hypospadias, in which the meatus is all the way back on the shaft of the [[penis]], near or within the [[scrotum]]. Shiny tissue that should have made the [[urethra ]] extends from the meatus to the tip of the glans; this tissue is called the [[urethral plate]]. The prevalance of hypospadias is highest in North America and lowest in Asia.<ref name="vanderhorst2017>{{REFjournal |last=van der Horst |init=HJ |author-link= |last2=de Wall |init2=LL |author2-link= |etal=no |title=Hypospadias, all there is to know |trans-title= |language= |journal=Eur J Pediatr |location= |date=2017-04 |volume=176 |issue=4 |pages=435-441 |url=https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5352742/ |quote= |pubmedID=28190103 |pubmedCID=5352742 |DOI=10.1007/s00431-017-2864-5 |accessdate=2019-10-23}}</ref>  The [[foreskin]] frequently does not develop normally.
