When I was researching TRT in the UK I noticed there was a lot of confusion about the NHS’ policies, inconsistencies etc.
I found what appears to be their internal policy document, including requisite levels for TRT consideration: www.nnuh.nhs.uk/publication/download/adult-testosterone-replacement-and-monitoring-jcg0043-v2-1/
Not sure if this has been posted already but figured it could be helpful for those investigating. It’s for a certain region (Norwich) but I presume policies like this are (should be) uniform across the NHS? Feel free to delete if unnecessary/ it has been shared already
