Effect of female nargile smoking on in vitro fertilization outcome.
OBJECTIVE
Smoking is a significant health hazard that has been associated with poor reproductive outcome and reduced fertility in reproductive age women. The aim of this study was to assess the effect of nargile smoking on intra-cytoplasmic sperm injection (ICSI) outcome.


METHODS
A prospective analysis of the outcomes of 297 women who underwent ICSI treatment at the ART Unit at the American University of Beirut Medical Center between January 1, and December 31, 2006 was done. The patients were divided into 3 groups based on their smoking status: cigarette smokers (n=42), nargile smokers (n=51) and non-smokers (n=204).


RESULTS
The mean age of nargile smokers was significantly lower than the other groups; however, the 3 groups were similar with respect to the cause of infertility, total dose of follicular stimulating hormone (FSH), number of oocytes and embryos obtained, and number and quality of embryos transferred. There was no significant difference in the clinical pregnancy rate between nargile smokers and non-smokers (51.0% vs 43.6%). However, cigarette smokers had a significantly lower clinical pregnancy rate compared to non-smokers (23.8% vs 43.6%, p=0.0238). On multiple logistic regression analysis, factors that decreased the clinical pregnancy rates were cigarette smoking and maternal age.


CONCLUSIONS
Although this study did not find a deleterious effect of nargile smoking on ICSI outcome, the results need to be confirmed in prospective studies that would include larger number of women with more objective measures of nargile smoke exposure.
