"Plus, a person may have high levels of testosterone merely because their body is not efficient at using the testosterone it produces.
To combat this inefficiency, the body simply produces more to ensure proper usage.
This does not change one’s sex, nor is there any medically accepted threshold for how much testosterone or estrogen qualifies someone as male or female.

Chromosomes are not binary either.
There is a common misconception that XX/XY chromosomes are the only two combinations that exist to denote a male/female binary.

But some people are born with XXY and XXX chromosomes too, and these are only two examples of multiple chromosomal variations Intersex individuals, for instance, may have four different types of chromosomal variations.

Some intersex individuals with mostly male chromosomes can also carry fetuses to term if they have the anatomy necessary for pregnancy.

So in summary, even biological sex, which most people believe to be binary, is far more complicated than a strict male-female binary."

Barely related:

but I probably have PCOS, fibroid, endometriosis or something.
URGH. Fucking Gen AI slop art.
