Resumen
CARRENO FLOREZ, Grace et al. CYP1A1*2A polymorphism and infertility in Colombian Caribbean male subjects. Salud, Barranquilla [online]. 2015, vol.31, n.1, pp.1-9. ISSN 0120-5552.
Objective: The aim of this study was to investigate the association of CYP1A1*2A polymorphism (T-C substitution) with male infertility in Colombian Caribbean subjects. Materials and Methods: Macroscopic and microscopic characteristics were analyzed in the semen sample of 31 infertile and 20 fertile men. The polymorphism was genotyped through PCR-RFLP. Results: Both groups evidenced significant differences in microscopic characteristics (p< 0.05), as well as alterations in sperm motility, count and morphology. Three genotypes were identified: wild type homozygous (TT), heterozygous (TC) and variant homozygous (CC). 25 TT genotype (80.6%), 5 TC genotype (16.1%) and 1 CC genotype (3.2%) in infertile men, and 16 TT genotype (80.0%), 4 TC genotype (20.0%) and 0 CC genotype (0.0%) in fertile men were identified. In both infertile and fertile men, distributions of the genotypes were in Hardy-Weinberg equilibrium. Logistic regression analysis showed no significant association between CYP1A1*2A polymorphism and male infertility in Colombian Caribbean men (p>0.05). Conclusion: These preliminary results suggest that CYP1A1*2A polymorphism do not contribute to male infertility of Colombian Caribbean men. However, they are very important because there is limited information about CYP1A1 gene polymorphisms associated with male infertility.
