In a cohort study, women attending the IVF unit in 2006–2007 with favourable parameters for pregnancy (<38 years; less than three IVF cycles, transfer of two highest-grade embryos) grouped by smoking status were included. The cohort included 237 patients/cycles: 42 smokers, 195 non-smokers. The clinical pregnancy rate was significantly lower in smokers (35.7% versus 55.4%,P = 0.021, OR = 0.44 (95% CI 0.22–0.89)), even after conditional stratification on covariates (passive smoker, passive or partner smoker, age group). The live-birth rate was lower in smokers (28.6% versus 42.6%), but the difference was not statistically significant(OR = 0.54 (0.26–1.11)). Among non-smokers, there was no difference in pregnancy rate by passive or partner smoking. On logistic regression, variables predicting pregnancy were age <35 years (P = 0.008, OR = 2.58 (1.2–5.2)) and non-smoking (P = 0.003,OR = 3.47 (1.51–7.98)). In conclusion, transfer of high-quality embryos does not overcome the negative effect of active smoking on pregnancy rate in IVF treatment. The endometrium is apparently involved in the mechanism underlying IVF failure in smokers.
