Infertility is defined as an inability to conceive a child within one year of regular sexual intercourse. It affects up to 15 % of couples worldwide (WHO, 2010). The male factor contributes to the total infertility with more than 50 %. Fertility of a man is influenced by several factors such as genetic background, environment and various diseases such as diabetes mellitus (DM). Diabetes mellitus is a serious health problem that affects 451 million people worldwide (18-99 years) and the number of people with this disease still increases (Cho a spol., 2018). In addition, parenthood is postponed to middle age when the fertility decreases and metabolic diseases such as type 2 diabetes mellitus (DM2) appear. The aim of this thesis was to investigate the effect of type 2 diabetes on reproductive parameters of mouse inbred line C57BL/6J compared to the control group and the possible effect of paternal diabetes on the first filial generation. In the evaluation of the effect of DM2 on reproductive parameters, we used innovative methods to study internal state of sperm and testes. Results of our work showed that DM2 influenced the weight of body, prostate and liver. The weight of testes, epididymis and liver was reduced in the offspring. Furthermore, sperm morphology and intraacrosomal protein status were...
