What is Zinc?
Zinc (Zinc Gluconate) is an essential mineral composed of more than 300 enzymes. It’s needed to repair wounds, maintain fertility in adults and growth in children. It synthesizes protein, helps cells reproduce, preserves vision, boosts immunity and protects against free radicals, among other functions.
Zinc is a critical trace mineral for male sexual function. It is involved in virtually every aspect of male reproduction, including hormone metabolism, sperm formation, and sperm motility. Zinc is found in the seminal fluid, increasing sperm count, motility and blood testosterone levels.
How does it work?
Zinc is essential in spermatogenesis, or sperm creation. A Zinc deficiency causes decreased testosterone levels and sperm counts. Infertile men with low sperm counts often suffer from Zinc deficiencies, and it is widely believed that increased Zinc intake is the first step toward re-invigorating sperm creation.
Where does it come from?
Good sources of zinc include oysters, meat, eggs, seafood, black-eyed peas, tofu and wheat germ.
Safety / Side Effects
Zinc taken in excess of 300 mg per day has been reported to improve immune function.
Studies Involving Sperm
The effects of Zinc therapy on plasma testosterone (T), Dihydrotestosterone (DHT), and sperm count were studied in 37 patients with idiopathic infertility of more than five years duration. In the first group, (T less than 4.8 mg/ml; 22 patients), T and DHT rose significantly after oral administration of Zinc, as did the sperm count. Nine wives became pregnant, six within three months and three within two months of a second trial. Sperm count was unaffected by Zinc, while DHT increased significantly. (Hunt, et al, 1992)
Certain medicines may interact with Zinc. Consult with your physician or pharmacist to determine if any of your medications might interact with this supplement.
