Background and Objective:  Ongoing research suggests that cytochrome P4501A1 (CYP1A1) 3801T &amp;gt; C polymorphism may be correlated with human male infertility but the reported results are conflicting. Hence, this case-control study was conducted in Algerian population to determine the frequency of this polymorphism and its relationship to male infertility.  Methods:  This study included 173 subjects grouped into two categories: controls (84) and patients (89) with abnormal semen analysis parameters. Genomic DNA from the patients and controls was extracted and PCR-restriction fragment length polymorphism was used to genotype the 3801T &amp;gt; C CYP1A1 polymorphism.  Results:  In the control group, the frequency of homozygous wild-type TT, heterozygous TC, and mutant homozygous CC genotypes of the CYP1A1 T &amp;gt; C polymorphism was 84.52%, 13.10%, and 2.38%, respectively, while infertile men had 77.53%, 20.22%, and 2.25%, respectively. There was no correlation between the 3801T &amp;gt; C CYP1A1 variant and male infertility. Furthermore, the rs4646903 C allele was not a risk factor in the dominant genetic model.  Conclusion:  The 3801T &amp;gt; C polymorphism cannot be considered as a risk factor for male infertility in Algerian population. Our results need to be validated and confirmed through prospective studies with a larger number of patients. &#x0D; &amp;nbsp;
