In this concise segment, Dr. Anne Truong explains that prostate enlargement in older men is primarily driven by low testosterone levels and inflammation. She notes that heavy alcohol consumption can exacerbate prostatic inflammation. Conversely, men who engage in sexual intercourse at least three times per week tend to experience less prostate enlargement, a lower risk of prostate cancer, and potentially longer lifespans. Dr. Truong also provides a tangible reference for normal prostate size, comparing it to a walnut and stating that a typical prostate weighs about 30 grams.
