Fun fact: during early development the gonads of the human fetus remain undifferentiated; that is, all fetal genitalia are the same and are phenotypically female.

- So, if biological sex can't be changed,
- And if life starts at conception,
- Then all men are trans.

Sorry, Republican men. You made the rules.

Men lose Y chromosomes as they age. It may be harming their hearts

Study in mice is first to directly test health effects of losing male chromosome

@mlbellar @LadyDragonfly

So female is the alpha and omega of human development and temporarily developing into a male is just a 49% aberration? 😏 (for procreation purposes mayhaps?)

@brainwreck @mlbellar @LadyDragonfly
Yep, that sounds about right. Smarter, more humane, nurturing, generous, tender... Be like women. Oh, and just bask in the glow of the fact that they allow us to share the Earth with them.
@wellingtonrock @mlbellar @LadyDragonfly We're talking chromosomes and gametes here, society's gender roles have nothing to do with it.

@brainwreck @wellingtonrock @LadyDragonfly

If society's gender roles are fixed when natures aren't, things can get out of sync, just saying

@brainwreck @wellingtonrock @mlbellar

If chromosomes and gametes have the ultimate say in determining ones gender,
Then all old men are women.

Sorry, Republicans, you made the rules again.

@LadyDragonfly
I don't think it is the same.
Isn't female XX and Male XY?
And if part of Y lost more it doesn't make XX it makes it XI
@LadyDragonfly @brainwreck @wellingtonrock @mlbellar
This kinda breaks down the original argument.
If it’s the chromosomes that are the arbiter, then men were never females to begin with since the second chromosome is added by the sperm and therefore present at conception.
If the chromosome isn’t the arbiter then this article, instead, doesn’t suggest that sex is changed with age.
The first toot was better on its own 😉
@LadyDragonfly @brainwreck @wellingtonrock @mlbellar (add to that, that the article isn’t suggesting that men gets two X chromosomes with age, they’re losing the Y, which isn’t the same)
