Özet
Objective: The aim of the present study was to investigate serum ghrelin and orexin levels in patients with varicocele and compare these levels with idiopathic infertile male and healthy control cases. Methods: This study enrolled 24 men with varicocele, 24 males having idiopathic infertility, and 21 fertile men as the control group. Hormonal analyses, ghrelin and orexin levels were measured samples. Semen was analyzed after 3 and 5 days of sexual abstinence. Results: Serum ghrelin levels were statistically different among the three groups (p=0.015), and it was due to a statistically lower level in group-1 than the level in the control cases (p=0.012). On the other hand, serum orexin levels were lower than healthy subjects in infertile groups with/without varicocele, but there was no difference (p=0.685) among three groups. Serum ghrelin level showed a negative and significant correlation only with sperm motility (r=-0.646, p=0.022), there was no correlation with other parameters. On the other hand, serum orexin levels did not show a significant correlation with seminal parameters. Conclusion: Both new investigated peptides ghrelin and orexin have regulatory effects on testicular function. However, ghrelin has a more obvious and complex effect on spermatogenesis. Impaired seminal parameters, especially motility was associated with increased serum ghrelin levels in infertile patients, especially with varicocele. © 2020 De Gruyter. All rights reserved.
