Background
Male infertility due to spermatogenesis defects affects millions of men worldwide. However, the genetic etiology of the vast majority remains unclear. The present study was undertaken to assess the association of DNAH6 and ATPase6 genes in asthenozoospermia patients in the northern region of India.
Conclusions
Our study concluded that the presence of DHAH6 and ATPase6 genes had a significant impact on male infertility.
Methods
A total of 60 semen samples were collected for the study, of which 30 were from the case group and 30 were from the control group. The semen samples for the case group (asthenozoospermia) and control groups were collected from IVF and Reproductive Biology Centre, Maulana Azad Medical College, New Delhi. Sperm count and motility were classified as per World Health Organization (WHO 2021) protocol. A total genomic DNA was extracted as per the stranded TRIZOL method with little modification.
Results
In-vitro molecular characterizations of DNAH6 and ATPase6 genes in both groups were checked by Polymerase Chain Reaction (PCR). The 675 bp and 375 bp amplicons were amplified using PCR for ATPase6 and DNAH6 genes. Our study results showed a significant (P ≤ 0.05) null deletion of DNAH6 and ATPase6 genes in asthenozoospermia patients as compared to the control. We found the significant null deletion of DNAH6 in case 45.0%, and the control group was 11.7%. However, in the case of APTase6, it was 26.7% and 10.0%, respectively. Conclusions: Our study concluded that the presence of DHAH6 and ATPase6 genes had a significant impact on male infertility.
