Well, there are all sorts of genetic abnormalities that cause genetic males to appear female. But none that cause genetic females to appear as male.

Sure, there are any number of hormonal triggers, but if you miss all of them you appear female. Note, it's the appearance that relevant, because with these various syndromes they still tend to have testes rather than ovaries. It appears that the signal to produce a penis however requires an actual on signal.

Well actually there have been cases where the SRY gene (the one that triggers masculine development) has been translocated onto the X chromosome which means that a XX person can develop male sex characteristics.

As usual with sex-development it doesn’t seem to matter how much we know, it turns out to be even more complicated than that!
