It's very disappointing that this stance has been taken. I think the argument is that there is little evidence that testosterone helps with the other aspects mentioned. I think this is mainly because the research just isn't being done because there's not much money in it, as it's not a patentable drug.
I take it through a private practitioner for energy and brain fog and it makes a big difference to the quality of my life. She told me to tell my GP that it was needed for libido but they already know that's not the case. If your GP refuses to prescribe it for you, are you able to afford a private prescription? Some menopause specialists have a service just for testosterone prescribing for women already established on HRT.
