Lessons learnt from the variation across 6741 family/general practices in England in the use of treatments for hypogonadism.

Our analysis has indicated that variation between general practices in testosterone prescribing in a well developed health economy is only related to small degree (r2  = 0.27) to factors that we can define. This suggests that variation in amount of testosterone prescribed is largely related to general practitioner choice/other factors not studied and may be amenable to measures to increase knowledge/awareness of male hypogonadism, with implications for men's health.
