PMDS

Persistent Müllerian Duct Syndrome (PMDS) is an intersex trait in which one who is AMAB and has a typically male body has a uterus, fallopian tubes, and in some cases the top of a vagina connecting to their penis. If they are born with a partial vaginal, they may also have a case of cryptorchidism and be missing one or more testicle.

30-79% of people with this condition can't get an individual pregnant, however this is not always the case. In some cases, the individual with this condition can get pregnant themself, if they have sperm injected into them. One with this condition likely also has a light case of ambiguous genitals, a micropenis, and may also have 45,X/46,XY Mosaicism.

It is unknown how common this is, however at least 250 people with PMDS have been reported in the medical literature.

History
PMDS was first described by Nilson in 1939 in a young individual with 45,X/46XY Mosaicism.
