In the village where girls return to boys after their penis comes out

Girls in a remote Caribbean village return to boys when puberty begins. This is due to a rare genetic disorder.

A 90 child born in Salinas, Dominican Republic, is transformed from female into male after starting to grow a penis.

They are known as "guevedoces," which translates "penis at the age of 12. The term used for them in medicine is whyudohermeaphrodites.

Fenomen has been explained by the BBC in a documentary.

Rare genetic disorder is caused by a lack of enzyme, which blocks male hormones in the womb.

This creates what looks like a woman in the east.

But at the age of puberty, when testosterone flows, the voice changes and they begin to grow the male reproductive organ.

The BBC announcer said they are sometimes even called "machihembras," which means "initially a woman," then a husband.
