There does appear to be a relationship between benign prostatic hypertrophy (BPH) & diabetes, prediabetes &/or insulin resistance. Metformin is the most common drug given for DM & IR. John sent me a study indicating that metformin may decrease the viability of BPH cells. It was intriguing.

It clearly indicates a relationship. There were both time and dose relationships (inverse relationships) between metformin & BPH cells. Metformin is not being proposed as a treatment for BPH. This is being provided for 2 reasons:
1. to help motivate proper control of DM & IR; and
2. to consider a possible mechanism involving IGF-1.
