The association study between tumor necrosis factor-receptor 1 36 AG (TNFR1 36 AG)‎ gene polymorphism and Azoospermic infertile men in Erbil city

Abstract EN

Tumor necrosis factor-alpha (TNF-α) is a multifunctional cytokine that controls cellular activities related to spermatogenesis.

(TNFR1) affects TNF- α activity and also may leads to gene dysfunction and male infertility.

This retrospective study was done to assess the linkage of TNFR1 36 A/G gene polymorphism with idiopathic azoospermia in Erbil City.

The present study was carried out on 98 infertile, 109 fertile males as healthy control.

TNFR1 36 A/G gene polymorphisms were detected in all study subjects, and their seminal fluids were analyzed.

Polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method is used for identify polymorphism in both cases and control groups.

MspA1I restriction enzyme were digested PCR products.

Digested and PCR products were analyzed by 3% gel electrophoresis for 45 minutes at 97 V.

.

The results of the present study showed that the incidence of AG genotype in azoospermia male higher than control groups (OR=2.069(1.154-3.708), P=0.014, this study found that G allele frequency in azoospermia men had a significant difference compared to the control group (OR=1.487 (0.992-2.170).

Moreover, AG genotype and G allele associated with an increased risk of non-obstructive azoospermia in Erbil City.
