Poor Oral Hygiene linked to Decreased Fertility

Research at the University of Western Australia has shown a link between gum disease in women and a reduced chance of conceiving. In fact, gum disease is statistically as bad in this respect as obesity, delaying conception by 2 months (extended from 5 months to 7). 

Gum disease in prospective fathers has been shown to reduce sperm quality too.

So, if you want to have a baby, you need to make sure you're both brushing and flossing properly. It would also be a good idea have a check-up and a session with the hygienist.
