PPSH

PPSH (Pseudovaginal Perineoscrotal Hypospadias) is an intersex condition in which a CTM individual has male chromosomes (XY) however their body does not not produce enough of a hormone called dihydrotestosterone (DHT) which causes more feminine developments within the body. Because of this, the individuals likely will have vaginas, ambiguous genitals, a smaller than average penis, or a non-fully formed penis. Because of this, they are often assigned female at birth, despite their male genetics. If they have a penis, they often have a urethra opening that is on a unusual spot of the genitals (hypospadias.) They may also have AMAB hypogonadism because of this.

Individuals with this condition often have a deepened voice, increaed muscle mass, and very little body hair during puberty, making their puberty (in most cases) usually quite androgynous in nature.

This is a rare condition and the exact rarity is unknown. Those with this condition often are fertile and can produce sperm and parent children, so long as they have horomone or medical assistance (HRT.)

History
It is unknown when this condition was discovered, however it has been discovered since 2005.
