ARENT, Adriana et al. Effect of cigarette smoking on laboratorial outcome of in vitro fertilization. Rev Colomb Obstet Ginecol [online]. 2004, vol.55, n.4, pp.287-292. ISSN 0034-7434.

Objective: to evaluate the influence of female cigarette smoking on laboratory results of in-vitro fertilization (IVF). Design: cohort study. Patients and methods: a total of 119 infertile couples, who were submitted to the first cycle of IVF due to tubal factor, were divided in three groups: non-smokers women (n=81), passive smokers women (n=15) and active smokers women (n=23). The laboratorial results of IVF were analyzed among the sub-groups. Results: women who smoked had a lower fertilization rate (40.7 %) and a worse embryo quality (70.6%) than the non-smokers (59% and 81.3%) and the passive smokers (67.4% and 87.9%) (p<0.05). There were no significant differences on the number of oocytes retrieved and embryo cleavage rate between the different groups. Conclusions: the results of this study indicate that the success of IVF can be affected negatively in the smoker women, due to smaller fertilization rate and the worse embryonic quality.
