Can you ever truly change your sex/gender?Watch
Do you think you can ever change your gender?
Can a man ever be a woman or vice versa
Gender; I guess so but it's not scientifically or biologically correct
Sex is just hormones and organs, there's no reason why it can't be changed.
But trying to actually become a member of the opposite sex is no more achievable than trying to become a member of a different species. No matter how many traits of the opposite sex you manage to acquire, your genes will always be that of whichever sex you were born into.
And many species, even species of mammal have more than two 'morphs', one fish specvies has five morphs of male and seven morphs of female - until recently people thought some of these were different species. Do humans have more than two morphs? Maybe.
The practical (and only legal basis in the UK, until recent legislation) approach is to use exterior genitals (at birth), and this generally does correspond with the social role an individual will adopt. This does mean that throughout history, and today, individuals with (CAI syndrome) undecended testicals and female exterior genitalia were/are classed as female, married men, but were actually infertile.
Don't look to genetics for help either! But that's too big a topic, although I will mention that we are probably all genetic chimaeras. Also complicated is gender identity. Trouble is here, we are trying to fit infinitely diverse individuals into rigid categories, based on our limited understanding at any time, when we should simply accept a person as who they are. After all, do we really need M or F on a birth certificate in these days of supposed equality?
