1. Zinc and Male Sexual Health
Zinc is an integral part of the male hormonal system, and a primary part of semen. It plays a major role in the production of sperm. 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. Zinc increases sperm count and sperm mobility. High zinc levels also means lower levels of estrogen and prolactin, thereby reducing the risk of prostate disease.
2. Zinc Deficiency and Prostate Enlargement
Adequate zinc also prevents the formation of dihyrotestosterone (DHT). When testosterone levels decline, the prostate gland converts the testosterone to dihydrotestosterone. This testosterone is 17 times more potent than testosterone. Unfortunately, DHT breaks down testosterone causing a range of problems including prostate enlargement, potential prostate cancer, and even male baldness since it can damage the hair follicles. This makes zinc an essential nutrient for overall male health on multiple levels.
3. Scientific Studies and Zinc
Irving Bush, M.D., senior consultant at the Center for Study of Genitourinary Diseases in West Dundee, Illinois, and former chairman of the FDA panels on gastroenterology, urology and dialysis, studied the affects of zinc on enlarged prostates. Nineteen men with enlarged prostates took 150 milligrams of zinc sulfate every day for two months, followed by 50 to 100 milligrams a day as a maintenance dose. 14 of the 19 men experienced shrinkage of the prostate.
Another study at the University of Edinburgh Medical School in Scotland discovered that high doses of zinc inhibited the activity of the enzyme that converts testosterone to dihydrotestosterone in test tube prostate tissues. As discussed above, dihydrotestosterone can be a major cause of prostate enlargement.
4. Food sources of zinc
Oysters are naturally high in zinc. One of the best sources of zinc is pumpkin seeds. Pumpkin seeds can relieve the frequency and urgency of nighttime urination associated with enlarged prostate. Other sources of zinc include Rye and sourdough breads, and wheatgerm.
5. How Much Zinc To Take
Most doctors and health practitioners believe that taking 80 milligrams a day can help an enlarged prostate, however this is not set in stone. Some say that more is needed, while some say less. Too much zinc is potentially toxic. It can lead to a mineral imbalance, meaning that it can absorb other minerals, leading to anemia and immunity problems. It is therefore important to consult with your doctor when determining the appropriate amount.
