S   ex change operations are where the female sexual organs are changed into male or vice cersa
Wow. That sounds like it could be a big change in your life... have you met anyone who has had a gender change?
No, I think it relates to s  ex reassignment through surgery or therapy tho
Yes exactly. So they change their gender through surgery. I met someone who uses a different gender but didn't have an operation.
Eels and clownfish are known to change their reproductive functions as well
What? That's so crazy. How do they do that?
the process is called sequential hermaphroditism'
