Abstract

Abstract: The aim of the present study is to evaluate the presence of ghrelin and orexin in the testicular tissue of patients who have undergone microscopic testicular sperm extraction (micro‐TESE) due to idiopathic non‐obstructive azoospermia. Seventy azoospermic cases were included in this study; serum hormone levels were measured and genetic investigations were performed. The patients were divided into two groups: micro‐TESE (+) and micro‐TESE (−). The number of Leydig cells and stained cells in the seminiferous tubules were counted under a light microscope, and we analyzed ghrelin and orexin activity. The relationship between serum hormone levels and ghrelin and orexin distributions in testicular tissue was evaluated according to micro‐TESE results. While sperm was found in 33 cases (47.1%), micro‐TESE was negative in 37 cases (52.9%). Peptide hormone activity in testicular tissue was higher in micro‐TESE (+) cases. However, interstitial orexin (p = 0.038) and ghrelin (p = 0.002) activity showed statistically meaningful differences. Many different peptides, genes, and other unknown mechanisms play important roles in testicular function. In particular, the peptides orexin and ghrelin may play regulatory roles in testicular function in humans.
