TT - total testosterone, LH - luteinizing hormone, FSH - follicle stimulating hormone, SHBG - sex-hormonebinding globulin, FT - free testosterone, CV - cardiovascular, CVD - cardiovascular disease, T Therapy -testosterone therapy, HCG -human chorionic gonadotropin, SERMs - selective oestrogen receptor modulators, AIs - aromatase inhibitors, PSA - prostate specific antigen,

*For men with TT levels <5.2nmol/L plus low LH and FSH or increased prolactin levels, refer to endocrinology or arrange a pituitary MRI to exclude a pituitary adenoma3,6

**These drugs should not be used if pituitary function is compromised. SERMs and aromatase inhibitors are not currently licensed for TD
