sighs. Okay, here some actual science:

In the womb, biological sex begins.

Science says we all start as phenotypically (observable physical or biochemical characteristics of an organism, as determined by both genetic makeup and environmental influences) female meaning we'd all come out of the womb in aprox 9 months as females if a gene called SRY on the Y chromosome didn't activate after around 5 to 6 weeks. This gene suppresses some of the X chromosome functions, and activates characteristics of biological male physiology.

Ovaries descend and become testes.

Labia majora fuses to become the scortum.

Embryologically, the uterus, cervix and vagina along with the Fallopian tubes develop from the Paramesonephric duct in the female. In the male, the Paramesonephric duct develops into the prostatic utricle and the testicular appendix.

Instead of a clitoris with much more nerve endings, one ends up with a penis. Male and female sex organs become absolutely different and unique.

In conclusion: There is no womb in a male's prostate. They share a genetic origin (X chromosome), but they're not the same thing nor are they within one another. Thanks to Y chromosome it kicked in and partially suppressed the X chromosome functions in order to produce a dudebro.

I am tired of saying this. It is not just the SRY gene. It's the presence of BOTH X chromosomes.You need both to became female.

There is a lot that medical research still doesn't know about chromosome and gene function. Within another couple of decades we will probably discover there are a lot more nuanced details about how the Y chromosome differentiates female and male physiology.

I will tell you what we know for sure :If one of the X chromosomes is missing or has damaged/missing areas this is the result

That's fascinating, thanks for sharing. I've seen transgender promoters make claims like the Y chromosome is useless beyond reproductive attributes. But nobody knows if that's true because the scientific research is still very early. From what I can gather, researchers don't even fully know what all the genes on the Y are responsible for.

A study was just released that has discovered a correlation between chromosomal gene expression and brain attributes. "Researchers have long observed consistent sex-based differences in subcortical brain structures in mice. Some studies have suggested these anatomical differences are largely due to the effects of sex hormones, lending weight to a "gonad-centric" explanation for sex-based differences in brain development. However, more recent mouse studies have revealed consistent sex differences in cortical structures, as well, and gene-expression data suggest that sex chromosomes may play a role in shaping these anatomical sex differences. Although the mouse brain shares many similarities with the human brain, it is not clear whether these key findings in mice also apply to humans."

Further research on this, if it's not suppressed, could very well blow the common transgender dogma of "I have an opposite sexed brain" out of the water. But that would be scientifically objective, and science is inconvenient when claiming that feelings are the basis of truth.
