Most people understand that smoking can effect their fertility. I just wanted to add a bit of information discussed by IVF specialist Dr. David Carnovale MD who said when a woman smokes this can decrease the chances of an IVF procedure working by 50%. Now most times the odds that IVF will work aren't the best anyway, so to further decrease this by 50% is really an issue.
Also keep in mind Dr. Carnovale MD says that men who smoke are likely to be effecting the quality, shape and production of sperm as well.
With the cost of IVF being what it is, it's very important that a couple addresses all issues that could impact the results.
However it is important that if you are going to plan to quit smoking that you make sure you have a good look at your eating plan right now. Adjust your eating plan to be as healthy as you can be to decrease your chances of significant weight gain when you do quit.
