Aquaporin-9 immunohistochemistry in varicocele testes as a consequence of hypoxia in the sperm production site.

abstract：:Insulin-like factor 3 (INSL3) has an important role in the human reproductive system; however, its detailed function is still mysterious. We aimed to investigate the possibility of expression of RXFP2 receptor on human spermatozoa and to determine the anti-apoptotic and antioxidant mechanism derived the binding of INS...
