What basis do you have for making these assumptions?
It seems rather unscientific to make such baseless claims about a very specialised area most people don't have knowledge of, and mentioning anecdotes about your wife is totally irrelevant...

The other is an assumption that someone's observed characteristics are caused by one particular hormone level, with no evidence to support that.
You could attribute her height and preference for fatty fish to her T levels too, if you strained hard enough.
But this is subject to placebo effect, as the OP said, so you can't directly infer a casual influence on behaviour.

The OP did not say the lack of maternal instincts was caused by lower than normal testosterone, they simply noted that she had both characteristics.
