According to the World Health Organization (WHO), 15% of couples in reproductive age suffer from infertility problems, and up to 60% of cases are caused by male factor. This could be caused by genetic background, environmental factors and various diseases, including diabetes mellitus (DM). However, the impact of DM on male fertility is not fully understood. . The aim of this study was to investigate the effects of DM on reproductive parameters and sperm quality, using mouse model. DM (type 1) was induced by Streptozotocin in FVB inbred mouse strain. Mice with blood sugar levels higher than 13.9 mmol/L were considered diabetic. After 4 weeks of diabetes exposure, diabetic males were bred with wild type females and transgenerational effect of DM was assessed. Selected morphological, cellular, and molecular parameters of diabetic males and their male offspring were compared to appropriate controls. There was an increased in sperm fragmentation and abnormalities of sperm morphology in diabetic mice in both generations. An increased staining with apoptotic marker annexin V was also detected in the diabetic groups. Furthermore, a presence of protamines as major sperm nuclear proteins was analysed. Protamine 1 to protamine 2 ratio (P1/P2), a marker of male fertility, was altered in sperms of experimental diabetic animals in both generations. Our findings indicate that DM type 1 negatively affects sperm quality and P1/P2 ratio and this negative effect is transmitted to the progeny
