TÜP BEBEK MERKEZİNE BAŞVURAN AZOSPERMİK OLGULARDAN ALINAN SEMİNİFER TÜBÜL ÖRNEKLERİNİN ULTRASTRÜKTÜREL VE HİSTOPATOLOJİK OLARAK İNCELENMESİ

Abstract

Objective: In this study we purposed to explore seminiferous tubules via histopathological and electron microscopic methods in testicular biopsy samples obtained TESE and the relationship between the findings and levels of serum FSH, LH, testosterone hormones. Methods: Azoospermia patients were divided into two groups, a positive testicular sperm extraction (TESE(+)) and a negative testicular sperm extraction (TESE(-)). Testicular tissue from biopsy samples were subjected to the light and electron microscopic tissue preparations. Serum hormone levels of patients were determined and analyzed statistically between the groups. Results: Compared the groups, more remarkable damages were detected in the seminiferous tubulus of no sperm group in the light and electron microscopic examinations. Although inflammation and partly tubule degeneration was observed, spermatogenesis and sperm cells were determined in the tubules of sperm pozitive group. In the light and ultrastructural analysis of negative sperm group, macrophages and mast cells in the interstitial tissue, vacuolization of seminiferous tubules, lipid inclusions and Sertoli cell only syndrome were the significant findings. When analyzed serum FSH, LH and testosterone hormones between the groups, FSH and LH hormones were statistically significant while Testosteron hormone was not significant. Conclusion: As a result in the seminiferous tubules of individuals histopathological results revealed that FSH and LH are important indicator of testicular function but Testosteron has not any effect. It was concluded that high levels of these hormones impair spermatogenesis and cause testicular failure.
