Penoscrotal Transposition (PST) is a trait that - in some cases - may be considered an intersex trait. This trait effects AMAB/CTM individuals, in which ones scrotum (the skin that covers the testicles) is in the front or at the sides of the penis instead of being behind it.
Those with this trait typically are also partnered with hypospadias, cryptorchidism (in this case, the skin covering the penis would be full of empty tissue) anal issues, mental disabilities, growth deficiencies, and issues within the nervous system.
Fertility depends on how one's body formed, whether or not they have fully formed or incomplete testicles, and whether or not the penis needed surgical intervention. The causes of this trait vary; however, it is usually due to a chromosomal or hormonal disturbance within one's genetic build.
This trait is not inherently intersex in and of itself, however it is often found partnered with intersex variations.
A Shawl Scrotum or Donut Scrotum is a subset of penoscrotal transposition in which the scrotum surrounds the penis in a mannerism that is best described as appearing in a shawl-like manner.
Penoscrotal transposition was reported for the first time by Appleby in 1923.
