Guevedoces, a specific type of intersexuality. Those with this intersex condition have no testes, so they are called "females", until around the age of 12 where they develop male genitals. They are females that become males

You really are misinformed.

Guevedoces are XY persons from the Dominican Republic with a genetic enzyme deficiency known as 5-ARD, a condition that occurs in all populations around the world, and is most likely to occur in areas where consanguinity (procreation amongst close blood relatives) is common.

This enzyme deficiency makes it impossible to convert T into its more potent form, DHT. DHT is necessary for the male genitalia to form properly in utero. Hence, male children with 5-ARD are often born with unusual looking genitalia for their sex. Their penises are micro, misshapen or missing, causing some have shallow skin pouches that go inwards rather than outwards; their urinary anatomy is atypical (if they have an indented skin pouch, the urethra usually empties into it); their testes are undescended; and their flattened scrotal skin often resembles & gets mistaken for labia.

Undescended testes are either remain inside the abdomen - where they form originally in the early stage of development - or they are in the inguinal folds in the groin rather than located inside the scrotal sac. Undescended testes are not missing testes - they are just testes in a location that is not customary. Said testes have simply not completed all the steps in the journey from inside the abdomen where they started to inside the scrotal sac on the exterior of the male body where testes are supposed to end up.

Despite their atypical location, the testes of XY persons with 5-ARD function entirely normally. They produce normal amounts of testosterone for males at the same stages in life that other males do. Moreover, XY persons with 5-ARD have male-typical sensitivity to T coz they have fully functioning male androgen receptors.

As a result, XY persons with 5-ARD go through male puberty, and male puberty masculinizes these children in nearly all the customary ways. The only differences are that XY persons with 5-ARD tend not to develop beards or much in the way of body hair like other males do, and their adult prostates are usually smaller than usual and produce less fluid.

During puberty, XY males born with micro penises that originally were mistaken for large clitorises experience significant penile growth as other males customarily do. Hence, in the DR, the condition is also known as "penis at 12."

In the DR, as in the rest of the world, the majority of children with XY 5-ARD who were mistakenly sexed as female in infancy realize & accept they are male during/after puberty and adopt a male/masculine mode of dress & "gender role."

After puberty, the testes of XY persons with 5-ARD can make sperm. With medical assistance, XY persons with 5-ARD can father children, and many have.

Here's a video showing two persons to whom the government of South Africa has issued ID documents saying they are legally female. But one of them is actually an XY person with 5-ARD. Most people can easily tell the difference; can you? https://youtu.be/Hvg50P4FwTk

5-ARD also occurs amongst XX humans. But in XX persons, 5-ARD has no effect on sex development; most girls & women with the condition will go through life unaware they have it. In other words, 5-ARD is a male-only DSD and a medical "condition" only in males. The fact that guevedoces have 5-ARD DSD is just further confirmation that they are male, not females who became males or an "in between" sex.

What about intersex conditions in which a male has a womb and fallopian tubes? (e.g. Persistent Müllerian duct syndrome)

Males with PMDS have Mullerian structures, or remnants of them, because at a specific point their sex development in utero went slightly awry. They do not have functioning uteri and Fallopian tubes. Though their testes are often undescended like in males with 5-ARD, their testes function normally, and they have normal looking and functioning penises. They are males with anomalies, just the way they'd be if they had extra toes or fingers.

You really need to learn about how human beings develop inside their mothers' bodies from the moment of conception on before you make any more of these nonsense posts. You are just waving a big red flag alerting others to how little you know.

Also, by spreading misinformation you are fostering precisely the kind of misunderstanding of DSDs that historically has caused persons with these conditions to be portrayed as "freaks" and stigmatized and ostracized as a result. This is unconscionable, particularly in 2021 when all the various DSD conditions are well understood and explained by science. Please stop.

This is a great resource that explains DSDs in general, and each one individually, in clear & easy to understand ways. Transcripts are provided for each video, and all the scientific sources are cited.
