It has been noted that an increasing number of young couples are having difficulty conceiving.

While many factors have been examined, one of the most powerful demonstrations has been the effect of monosodium glutamate (MSG) on the reproductive systems of both males and females.

Most studies have found that large doses of MSG can damage the testes, mainly the seminiferous tubules and the cells that form the sperm.

In one study, in which low doses of MSG were used, researchers also found significant damage to the germinal epithelial cells and Leydig cells that form sperm.

Sperm counts were much lower in the MSG exposed animals.

Females were damaged by MSG as well. In one study using female rats, researchers found significant damage to the animals’ ovaries, including the ova (eggs) themselves, along with degeneration of reproductive tissues.

Damage to the animals’ fallopian tubes after exposure to MSG was also noted.
