Male infertility is a multifactorial disease due to spermatogenesis impairment, with etiology remaining unknown for roughly one-third of infertile cases. Several studies have demonstrated that genetic variants are male infertility risk factors. CFAP43 and TEX14 are involved in the spermatogenesis process. The present study aimed to assess the association between single-nucleotide polymorphisms (SNPs) in CFAP43 (rs17116635 and rs10883979) and TEX14 (rs79813370 and rs34818467) and idiopathic male infertility in a Vietnamese population. A cohort of 206 infertile men and 195 controls were recruited for the study. CFAP43 and TEX14 SNPs were genotyped using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). Genotypes of randomly selected samples, accounting for 10% of the total, were confirmed using Sanger sequencing. The obtained data were analyzed using statistical methods. The results showed that 4 SNPs (rs17116635, rs10883979, rs79813370, and rs34818467) were in accordance with Hardy-Weinberg Equilibrium (HWE; P > .05). CFAP43 rs10883979 and TEX14 rs79813370 were associated with male infertility. For CFAP43 rs10883979, in the recessive model, the combination AA + AG was associated with male infertility when compared to the GG genotype (OR = 0.26; 95% CI: 0.06-0.85; P = .02). For TEX14 rs79813370, a protective effect against infertility risk was identified in the presence of the T allele of rs79813370 when compared to the G allele (OR = 0.48; 95% CI: 0.32-0.72; P < .001). Our results suggest that CFAP43 rs10883979 and TEX14 rs79813370 are likely associated with male infertility in the Vietnamese population, in which the G allele of rs79813370 may be a risk factor for male infertility.
