I've been a smoker for the past 16 yrs. Since I tried to have a baby, I cut down on smoking. I think smoking is not directly related to infertility. However, I recall I read some articles on smoking, alcohol & caffine effecting conception. Those "bad habits" are said to have bad influences to women trying to conceive. I wont agrue that. Pls, ladies, I know it's very difficult to give up smoking (or the others), do cut down the intake. Good lucky to u all
