The consequences of this disease turn out to be a significant problem for the patient, who tries to cope with the new condition his organism has been placed in. The most common effect of the disease, hyperglycaemia, leads over time to serious damage to various body systems, such as nerves and blood vessels. What is not widely known among the population is that diabetes may have harmful effects on the reproductive system of the men suffering from diabetes type 1 and 2 and that such a parameter could lead to or might be the reason for infertility problems for couples, for example, miscarriage or embryonic failure. AGEs is a number of products which are believed to play an important role, because their presence has been detected in increased level in diabetic men. This implies that those glycation products might play a key role in diabetic complications. Their receptor, RAGE, member of the immunoglobulin superfamily has been detected in the reproductive tract of diabetic men. Reactive oxygen species (ROS), a possible product of AGEs appear in high levels in seminal plasma and are believed to be the cause of DNA fragmentation. The objective of this review was to gather all the available material i.e. studies on diabetes mellitus in one article, to study the research which has already been conducted and the conclusions that have been drawn, in order to offer, if possible, new pathways and perspectives to the scientists, who focus on fertility problems, sometimes intractable.展开更多
