Smoking when ttc...

Hollie • Sun, Dec 07 • Ttc baby #2. His first, after a recent miscarriage.

They say smoking reduces your chances of conceiving by 50%... is it the nicotine that does that or all the.other nasty things in the cigarettes? I smoke about a half pack a day. But I have a electric cigarette that I'm thinking of switching to. Does anyone know?
