(NewsTarget) Zinc is an integral part of the male hormonal system, and a primary part of the semen. It plays a major role in the production of sperm. Studies also reveal that Zinc Deficiency may be a cause of Prostate Enlargement. As men age into their 50s and older, there is a natural decline in zinc. A zinc deficiency can lead to prostate enlargement, as well as a number of other male problems including impotency. This is because the prostate tissues are highly dependent on zinc to maintain its health and integrity.
