Abstract
AbstractObjectives: To evaluate the effect of anti-tuberculosis drugs (ATD) on indices ofreproductive capability, DNA fragmentation and offspring development of male ratswith testicular malfunction caused by experimental diabetes. Materials and Methods: Wistar albino male rats (body weight 160-200 g) were divided into threegroups: I - control, II - streptozotocin diabetes, III - streptozotocin diabetes + ATD.The testis DNA fragmentation was determined electrophoretically; spermatogeneticindices, offspring antenatal and postnatal development indices - by standardprocedures. Morphological analyses of gonadic structures were carried out by opticmicroscopy. Results: The study of the effects of diabetes and ATD administration ontestis cells morphologic and morphometric parameters and spermatogenesissuggested the presence of specific diabetes- and anti tuberculosis drugs - mediatedquantitative and qualitative changes in male rat reproductive organs,spermatogenetic epithelial cells, level and character of DNA fragmentation incomparison with normal rats. These changes were accompanied by alterations inprocesses of fertilisation (with intact females), embryogenesis and by lowering ofoffspring survival. Conclusions: Observed changes could hence affect the state andcorrect functioning of spermatogenetic epithelium and of other tissues ofreproductive organs, as well as offspring development in diabetic rats.
