if you mean an iron as in golf club it is good for whomever
Irons are good for men and women. Some people use them to make money, a lot of money.
Iron, as in Iron supplements should not be taken by men, as Iron deficiency is not commonly associated with males. Too much iron can lead to various health issues. Also, iron blocks the absorption of zinc, which is necessary for the immune system. All that being said, since this is the golf category, long irons, like my 4 iron, are bad for men because we can't hit them.
