Will hemotomochrosis ( too much iron in blood) effect a mans fertility?

Possibly: Hemochromatosis can be an infiltrative disease and that's important in fertility because if the pituitary gland is infiltrated with iron it can alter the signals to the gonads (testes and ovaries). Because of this, there can be a decrease in production of either sperm or eggs and that obviously isn't good when you're talking about fertility.
