Some parts of mainstream medicine are catching up with Dr. Peat.
Throughout their lives, men produce both testosterone, an essential male hormone, and small amounts of estrogen, a female hormone. As men age, the amount of active testosterone in the blood decreases, leaving a higher proportion of estrogen. The results of studies in animals suggest that BPH may occur because the higher amount of estrogen within the gland increases the activity of substances that promote cell growth. Diet and lifestyle may influence BPH in part via effects on reproductive hormones in susceptible men (3).
