I was prescribed testosterone privately. Testosterone is not licensed in the uk for women, so it is not likely you will be able to get it on the NHS. My initial appointment cost £ 180 and the follow up £140, then yearly appointments at £140. The testosterone was a gel in a pump that was easy to apply accurately. The pump cost £50 and lasted a while. The clinic also did implants, but this was not appropriate for me. The gynaecologist said it would be too strong and I might become rampant. Secretly I thought that might be a pleasant change! Sadly, I didn't find it helped me and I had to stop as I developed nasty acne like blemishes on my face, which have yet to subside completely. But I don't regret trying, particularly as you have to take HRT alongside. Oestrogen has made a big difference to my energy levels, but not libido. ( Cfs was being considered.)
