And you thought it was going to be "and drive." Well, you shouldn't do that either.
In the January 2011 issue of the journal "Obstetrics & Gynecology an article quantitates the effect of drinking alcohol on IVF success. In examining 4729 IVF cycles the authors found that women drinking at least four drinks a week had 16% less odds of a live birth than those who drank fewer than four drinks a week, When both the partners drank at least four alcoholic drinks a week, the odds of live birth were 21% lower compared with couples in which both drank fewer than four.
So in this New Year, don't drink and drive or do IVF. Seriously this is a factor over which you have control. Many factors are out of your control. Control what you can.
