I've never had mine tested either, but I have physical signs that point towards higher-than-average testosterone instead.
I think an important detail about the "little interest in sexual experiences" thing is that it's "little interest in sexual experiences with another person". So the question of whether there's any relationship to low libido is simply not addressed. Keeping with all the other bullet points, it's not about sexuality itself, it's still about the detachment from people being so pervasive that it overrides other things.
My testosterone has been tested 'normal' - so those traits in my personality are likely to be psychological rather than physiological. However, there's research going on now about how immune deficiency may effect the brain, and how it may be a cause of schizophrenia. I had a splenectomy at 10, and the spleen is part of the immune system (I have to take penicillin every day), so there may be a link there.
As it's all about fear and stress, the problem is that relationsships with the desired sex in most cases means fear and stress. The desires of schizoids are the same as those of the neurotypics, but fear and stress is in the way. In this respect I do feel as a man, but I don't feel or behave like being testosterone poisoned like most neurotypic males.
I have never been tested so I can't confirm 100%. While I may share some signs of low testosterone, it's more energy oriented, not sexually oriented. I attribute the energy issues more to dysthymia than anything else.
Mine is on the higher end and my libido is generally pretty high. I think the whole schizoids are not interested in sex needs to be revised. I am perfectly interested in having sex but I don't get attached or experience "love".
I was tested in 2015, when I was 24, and my results were 736 ng/dl. The reference range I was shown by my GP stated that men in my age range can float anywhere within the 250-830 ng/dl range, so I was not deemed to have low testosterone.
