Hypothesis: Women who smoke will have higher levels of infertility.
For this experiment we will need: Two groups of women aged 20-35. One of the groups of women will consist of smokers while the other one will have non-smokers. Both groups will come from the same area (i.e from the province of Alicante) to avoid too much disparity.
Once we have the two groups we will order the smoker group to smoke a minimum of 14 cigarettes per week.
