You’re the only one talking about this. A change can occur without any surgery. Reread the article to understand better, please.
You read the article and you even quoted it. It says how xx people can be men and how xy people can be women. Nobody said anything about any surgery or magic pill that grows a penis or whatever you’re imagining.
No, not magically, no. You’re right.
This article seems to disagree. But I don’t know much on the subject so I might be misunderstanding.
Also, no matter what the correct answer is, pretending the answer is binary is definitely wrong. Since it’s obviously a lot more complicated.
A person’s biological sex usually refers to their status as female or male depending on their chromosomes, reproductive organs, and other characteristics. Chromosomes are tightly packed DNA, or molecules that contain the genetic instructions for the development and functioning of all living things. Humans typically have forty-six chromosomes. Two of those are sex chromosomes that contain instructions for the development and functioning of characteristics related to biological sex, such as reproductive organs. There are two kinds of human sex chromosomes, X and Y. Individuals identified as males tend to have one X and one Y chromosome, while those identified as females tend to have two X chromosomes. However, other people are born with other chromosome combinations, such as XXY, that lead them to develop a mix of characteristics. People who fit that description are often referred to as intersex, a category for people whose bodies do not conform with stereotypical expectations of males or females at birth.
