Premature ejaculation is not a particularly precise term, but usually refers to ejaculation at the onset of sexual stimulation or before the man chooses. This condition affects millions of men and it has been the subject of many studies. It has also been the subject of product development in area outside of the pharmaceutical industry with many companies making claims that are unfounded.

The role of magnesium in premature ejaculation was the subject of a study in Kuwait. Knowing that magnesium levels are higher in semen than in serum, investigators designed a study that would evaluate whether or not there exists a relationship between magnesium status and premature ejaculation. The study revealed that semen magnesium levels were lower in the men complaining of premature ejaculation than others who did not have this complaint. The investigators theorized that perhaps magnesium is involved in semen transport and they suggest more research into this area.1

Magnesium is involved in the interaction of more than 300 enzyme reactions in the body. It is necessary for the transmission of nerve impulses, temperature regulation, detoxification, energy production and the formation of healthy bones and teeth. It is also vital for cardiovascular health. A U.S. Department of Agriculture study found that 75 percent of Americans do not get an adequate supply of magnesium in their diet. This is probably due to the absence of magnesium in many processed foods and the depletion of magnesium from agricultural soils in the U.S. Good food sources include nuts, legumes, cereal grains, and dark green leafy vegetables.
