There is a village in the Dominican Republic called Salinas, in which 1 in 90 of the people born are born as males, with testicles, but without a penis, because of misconstrued instructions at birth. In males, the gene on the Y chromosome, specifically the Sex Determining Region Y (SRY), instructs the gonads to become testicles. This leads to the creation of dihydrotestosterone which is a stronger version of testosterone. Dihydrotestosterone transforms the tubercle which all males and females have, into a penis. Females do not make dihydrotestosterone, therefore their gonads become ovaries, and the tubercle becomes a clitoris. Infants perceived as female at birth, due to a lack of dihydrotestosterone during fetal development, later develop a penis during puberty when testosterone triggers penile growth, as it does in typical male development. Those who lack the ability to create dihydrotestosterone, as is the case with those born as males but raised as females in the Caribbean village of Salinas, Dominican Republic where it is common, are technically male, but without a penis, a condition referred to as “5 alpha reductase deficiency”. This condition is quite well accepted in this part of the world and even has a term which is “guevedoce(s)”, (pronounced “guava-doh-chey”) which means “penis/testicles at 12” in Spanish. This condition whilst common in this region of the Caribbean, it is very rare in other parts of the world
