Is there influence of smoking on the mutagenicity of follicular fluid?

The mutagenicity of follicular fluid was examined in 24 patients, 12 smoking and 12 nonsmoking, who were treated in an in vitro fertilization program. The Salmonella microsome assay was used. It was found that the mutagenicity of follicular fluid was not influenced by the number of cigarettes smoked. Urine samples of smoking in vitro fertilization (IVF) patients however showed a dose-dependent elevation of the mutagenicity.
