"The slowly increasing understanding and acceptance of intersex people exemplifies how scientists and society still have a lot to learn about biological sex and the ways sex determination occurs in humans. Though biologists have an understanding that chromosome combinations influence the biological sex that an embryo develops as, biologists still know very little about the specific genes and mechanisms that control the sexual development pathway. Additionally, there are many factors beyond chromosomes that influence the sexual characteristics a person develops, and scientists are continually uncovering more intricacies in the development process. Finally, the events that lead to atypical sexual development have to be further explored."

Fuck you.
