I thinking eventually science will be able to control the physical characteristic of the human body and probably manipulate the genetic code in some distant future if the human species is able to survive it's own stupidity. The Human is basically only differentiated by a few genes that exist on the Y chromosome because most of the stuff on the Y chromosome is gobbledygook . So what's all the fuss

A bit oversimplified, but since we're brainstorming at the kitchen table, I like where you're going with this 💅🏻

God , I so totally love kitchen table brainstorming

In regard to the thread title...so close, and yet so far.

this is very true. society decided a long time ago that there was a distinct and essential difference between those who had penises and ran on testosterone, and those who had vaginas and ran on estrogen. the truth is that it is a trait, just like hair or eye colour, that has nothing to do with who we are on the inside. we all start out the same in the womb; whether you're male or female is essentially a coin toss; i think a lot of us lost that coin toss.

maybe that's why I've never been into gambling of any kind.

No no no! The difference between M and F isn't directly due to genes at all, instead it's down to gonadal hormone production. Admittedly, most people with a Y chromosome end up developing testicles and then developing as male, however it's the testicular hormones that cause male development to take place, not the Y chromosome. This is something that's been demonstrated experimentally in a wide range of animal species. There's also a number of medical conditions in which the testicles fail to develop in a genetically male (XY) person, with the result that you end up with someone who is phenotypically female - they look and behave like a woman.

Here's a couple of examples on youtube of people who are genetically male, but whose testicles failed to develop:



As you can see, they look and behave just like ordinary women. With complete gonadal dysgenesis (which is what happened to both the women in these videos), the female internal organs ordinarily do develop, and with the appropriate HRT and donor IVF, it's usually possible for these people to fall pregnant and give birth.
