A grandfather went viral on social media after appearing wearing a T-shirt with the phrase: “There are 2 genders: one goes to the gynecologist and the other goes to the urologist. The rest go to the psychiatrist”.

The message was interpreted by many as a defense of the idea that only two genders exist linked to biological sex.

Although it is a brief and humorous phrase, its meaning touches on a topic that has been generating discussion for years: the difference between those who understand gender as an exclusively biological reality and those who consider that it goes beyond that definition.
