The PMDS flag.

Persistent Müllerian Duct Syndrome (PMDS) is an intersex variation in which one who is AMAB/CTM 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 variation can't get an individual pregnant, however this is not always the case. In some cases, the individual with this variation can get pregnant themself, if they have sperm injected into them. One with this variation likely also has a light case of ambiguous genitals, a micropenis, and may also have 45,X/46,XY Mosaicism and/or AMAB hypogonadism, and may possibly fall under aromatase excess syndrome

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

It is important to note that not all the symptoms listed in this page are guaranteed to occur in someone with this variation, as someone may only experience one or several of these symptoms, yet still hold the variation.


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


The PMDS flag was coined by Reign of the breadsticcs on May 7th of 2021. It has no confirmed meaning.
