Take 200 micrograms of selenium daily. Do not exceed the dosage as it is toxic at levels above recommended. Zinc 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 found in the seminal fluid, increases sperm count and mobility, and blood testosterone levels.
Zinc deficiency is characterized by decreased testosterone levels and sperm counts.
Zinc levels are typically much lower in infertile men with low sperm counts, indicating that a low zinc status may be the contributing factor to the infertility. The results from several studies suggest that zinc supplementation may be beneficial for men who have low sperm count and low testosterone levels. Testosterone levels also increased, and nine out of the twenty- two wives became pregnant during the study. In contrast, in the fifteen men with normal testosterone levels, although sperm count increased slightly, there was no change in testosterone level and no pregnancies occurred. Thus zinc appears to be effective in increasing male fertility when testosterone levels are low.
