Scientifically, what genetic traits result in a male being a femboy?
>low levels of FSH
>low T levels
>poor digit ratio
>short height
>proportionately small skeletal frame(small clavicles etc.)
>white skin
>small dick(length and girth)
>small ano-genital distance
>pretty face

Anything I'm missing? Sayuri Mattar checks most of the boxes but he's old now and has always had a really fucked up chin.

Maybe bpa estrogen poisoning? Gynomastia?
I would guess general fat distribution is emergent from t levels and bone structure, rather than any possible gene which specifically codes for fat distribution.

This is a huge cope, I know.
