[The effect of smoking on infertility treatment in women undergoing assisted reproduction cycles].
ABSTRACT The aim of the present study was to investigate the influence of smoking on different parameters in woman treated by IVF-ICSI. The total number of MII stage oocytes retrieved, number of embryos, embryos quality and implantation rate were measured. 32 women undergoing IVF ICSI treatment were classified as smokers and 30 non-smokers on the basis of medical history. Smokers had decreased number of retrieved oocytes compared with non-smokers (p<0.05) and lower embryo score (p<0.05). There was no statistically significantly difference between quality of embryos in both groups. Women who smoked had also statistically significantly lower pregnancy rate per cycle (3% versus 38%) (p<0.000001). The knowledge gained from these results regarding the effects of female smoking on ART procedures may help to create guidelines for clinicians and providing a forceful impetus for women undergoing IVF-ICSI to stop smoking.

ABSTRACT: The aim of this meta-analysis was to investigate whether any difference exists in success rate of clinical outcomes of assisted reproductive technologies (ART) between women who actively smoke cigarettes at the time of treatment and those who do not. An intensive computerized search was conducted on published literature from eight databases, using search terms related to smoking, assisted reproduction and outcome measures. Eligible studies compared outcomes of ART between cigarette smoking patients and a control group of non-smoking patients and reported on live birth rate per cycle, clinical pregnancy rate per cycle, ectopic pregnancy rate per pregnancy or spontaneous miscarriage rate per pregnancy, and 21 studies were included in the meta-analyses. Pooled odds ratios (OR) and 95% confidence intervals (CI) were calculated for the data, and statistical heterogeneity was tested for using chi(2) and I(2) values. A systematic review examined the effect of smoking upon fertilization rates across 17 studies. Smoking patients demonstrated significantly lower odds of live birth per cycle (OR 0.54, 95% CI 0.30-0.99), significantly lower odds of clinical pregnancy per cycle (OR 0.56, 95% CI 0.43-0.73), significantly higher odds of spontaneous miscarriage (OR 2.65, 95% CI 1.33-5.30) and significantly higher odds of ectopic pregnancy (OR 15.69, 95% CI 2.87-85.76). A systematic literature review revealed that fertilization rates were not significantly different between smoking and non-smoking groups in most studies. This meta-analysis provides compelling evidence for a significant negative effect of cigarette smoking upon clinical outcomes of ART and should be presented to infertility patients who smoke cigarettes in order to optimize success rates.Human Reproduction Update 11/2008; 15(1):31-44.
