In this study, we checked the morphology of Sertoli cell mitochondria in testis biopsies from patients with idiopathic non-obstructive azoospermia and patients with obstructive azoospermia who have normal spermiogenesis. The expression of 104 genes controlling mitochondria fission and fusion were analyzed in three gene expression datasets including a total of 60 patients with non-obstructive azoospermia. The levels of 7 candidate genes were detected in testis biopsies from 38 patients with idiopathic non-obstructive azoospermia and 24 patients with obstructive azoospermia who have normal spermatogenesis by RT-qPCR. Cell viability, apoptosis, mitochondria membrane potential, adenosine triphosphate production, oxygen consumption, and mitochondria morphology were examined in primary human Sertoli cells. Mouse spermatogonial stem cells were used to detect the cell supporting capacity of Sertoli cells. We observed that patients with idiopathic non-obstructive azoospermia had elongated mitochondria. MTFR2 and ATP5IF1 were downregulated, whereas BAK1 was upregulated in idiopathic non-obstructive azoospermia testis and Sertoli cells. Sertoli cells from patients with idiopathic non-obstructive azoospermia had reduced viability, mitochondria membrane potential, adenosine triphosphate production, oxygen consumption rate, glycolysis and increased apoptosis. Knockdown MTFR2 in Sertoli cells increased the mitochondria size. Knockdown ATP5IF1 did not change mitochondrial morphology but increased adenosine triphosphate hydrolysis. Overexpression of BAK1 reduced membrane potential and upregulated cell apoptosis. The dysregulation of all these three genes contributed to the dysfunction of Sertoli cells, which provides a clue for idiopathic non-obstructive azoospermia treatment.<\/jats:p>","DOI":"10.1093\/biolre\/ioad150","type":"journal-article","created":{"date-parts":[[2023,10,30]],"date-time":"2023-10-30T23:25:52Z","timestamp":1698708352000},"page":"408-418","source":"Crossref","is-referenced-by-count":7,"title":["Dysregulation
