After reading another article, it seems she has some form of AIS (androgen insensitivity syndrome), which is what I was talking about in the original thread a few wks back.. I say this after reading about the undescended testes she has.. In this condition, the subject is a 46XY phenotype (technically male), but their body doesn't respond properly to androgens.. So what happens is, testes are first produced in utero, but all the other changes that should happen after, which differentiate a male from a female, don't happen.. So the external genitalia remains female, even tho there is no womb or ovaries.. It just goes to show you that by default, all fetuses are female.. When the child is born, there is usually no question on gender (which should appear totally female), but the clitoris could be enlarged in some uncommon cases.. At puberty, testosterone levels rise, but the body is insensitive to androgens - so little to no pubic/axillary hair develops.. And just as it's the enemy of many on here, some of that testosterone aromatizes into estrogen, which allows for breast development and other female traits.. It's not until a few years later that they grow suspicious when there's no menstruation.. The outlook is generally positive for these apparent female, except they're obviously infertile.. Sometimes the vagina is shallower than normal, but the patient is able to overcome this at home with a little device of some sort.. And lastly, Dr's will almost always recommend that the internal testes are removed, but the patients usually say they never feel the same after, even with HRT.. A complaint is their libido isn't the same, which makes total sense, since testosterone makes women horny (and they have pretty high levels of it).. And the females with this condition don't always look manly like this runner.. They're usually gonna look totally female, but usually be taller and with larger breast development than normal.. There are also other variations of AIS tho, where a the subject could appear male and have micropenis, but this is less common.
