Lycopene Protects Human Prostate


Prostate gland is a particular organ of males. It was found in the prostate, lycopene concentration is higher than other carotenoids. Therefore, studies on the effect of lycopene in protecting human prostate were developed widely around the world.  Lycopene’s excellent antioxidative effect reduces the occurrence or progression of prostate cancer among men. Clinical and statistical studies pointed that the incidence rate of man prostate cancer in Italy is lower compared to other counties because of the high dietary consumption of tomato products in Italy. Early in 1995, the researchers from Harvard Medical School found an inverse association of intake of carotenoids with risk of prostate cancer, and the major functioning compound is lycopene rather than other carotenoids.

 The growth of human prostate epithelial cells causes prostate enlargement. It was reported that lycopene inhibits the growth of normal human prostate epithelial cells, and eventually releases the urination problem caused by prostate enlargement.

 Recently, a clinical study investigated the effects of lycopene supplementation in elderly men diagnosed with benign prostate hyperplasia (BPH). The result of this clinical data directly proved that lycopene inhibited progression of BPH.
