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
