What is "male"?

The category "male," a biological and social construct, is determined differently across time and space. While the fluidity of gender, of "masculinity" is pretty easily seen, the fluidity of biology, of sex, is not always so evident. However, in the case of a small town in the Dominican Republic, guevadoces, the fluidity couldn't be clearer.

Guevadoces are people whose genitals don't fully develop until they are 12 years old. 

the Guavadoces . . . are deficient in an enzyme called 5-α-reductase, which normally converts testosterone into dihydro-testosterone. So they appear female when they are born, but around puberty, when they get another surge of testosterone, they sprout muscles, testes and a penis.

The article doesn't seem to understand the connection between sex, gender, and sexual preference. Nor does it speak with sensitivity about the issues of sex, identity, and biology. It does provide a unique case to ponder, however.
