Boy girl discovering sex together

Puberty can be an awkward time for anybody, but spare a thought for the Guevedoce children of the Dominican Republic, who literally appear to change their sex when they hit adolescence. As covered by Michael Mosley in the BBC series, Countdown to Life: The Extraordinary Making of You , the remarkable case of the Guevedoces is a condition that affects just over 1 percent of the boys born in Salinas, a remote village lying in the southwest of the Dominican Republic. Guevedoces literal translation "penis at 12" - who are also called " machihembras ", meaning "first a woman, then a man" - appear to be completely female at birth and are brought up to be little girls. After the developments of puberty, Guevedoces grow up to be fully functional males in their society, although some telltale signs do give away their unique biological heritage. Not all Guevedoces in the Dominican Republic change their name upon hitting puberty — some grown men in the region have female names throughout their life. The condition is not isolated to just the Dominican Republic, it's also been observed in Turkey and New Guinea.

Medical researchers at Melbourne's Murdoch Children's Research Institute have made a new discovery about how a baby's sex is determined -- it's not just about the X-Y chromosomes, but involves a 'regulator' that increases or decreases the activity of genes which decide if we become male or female. An embryo with two X chromosomes will become a girl, while an embryo with an X-Y combination results in a boy," Ms Croft said. High levels of the SOX9 gene are needed for normal testis development. Lead author of the study, Professor Andrew Sinclair, said that 90 percent of human DNA is made up of so called 'junk DNA or dark matter' which contains no genes but does carry important regulators that increase or decrease gene activity. If these enhancers that control testis genes are disrupted it may lead to a baby being born with a disorder of sex development.

These early moments are when the foundations for learning, health and behaviour are formed and they are the same for children of all genders. Around the age of three, children begin to develop a sense of gender identity, which continues to solidify as they get older. By the age of 5, children have a sense of gender stability and begin to express their gender identity through both words and actions.
