Putting his penchant for data analysis to practical use, Richie Cotton, compiled a chart to help himself and his girlfriend understand how long it will take for them to conceive.

Women tend to be less fertile as they get older, but how much, exactly? Math nerd Richie Cotton at 4dpiecharts.com decided to figure it out with a chart.

Cotton, who is trying to have a baby with his girlfriend, used data from the Journal of Human Reproductie Sciences and Social Fertility to figure out "monthly fecundity rate," or likelihood of getting pregnant each month if you're having sex without birth control.
