Nature vs nurture?; the chicken or the egg?; I think therefore I am! Eventually [exponentially] ->-bleeped-<- will be accepted as a fact of life by almost everyone without question, but a scientifically proven explanation of the cause and effect would definitely speed up the process. When I first started my transition, I wanted a biological answer, so I had a karyotype test done to check for Klinefelter's, since I have a lot of characteristics, but the test showed I am not intersex, but I wasn't convinced (and I'm still not to some degree) that I didn't something else like androgen insensitivity, but the farther I got into my transition, I realized that it didn't really matter, because I am real, and my feelings and thoughts are real and valid, so I do not need some type of medical diagnosis to justify my experience; I am living proof of it.
