Diabetes is a chronic metabolic disorder characterized by hyperglycemia and associated with many health complications due to the long-term damage and dysfunction of various organs. A consequential complication of diabetes in men is reproductive dysfunction, reduced fertility, and poor reproductive outcomes. However, the molecular mechanisms responsible for diabetic environment-induced sperm damage and overall decreased reproductive outcomes are not fully established. We evaluated the effects of type 2 diabetes exposure on the reproductive system and the reproductive outcomes of males and their male offspring, using a mouse model. We demonstrate that paternal exposure to type 2 diabetes mediates intergenerational and transgenerational effects on the reproductive health of the offspring, especially on sperm quality, and on metabolic characteristics. Given the transgenerational impairment of reproductive and metabolic parameters through two generations, these changes likely take the form of inherited epigenetic marks through the germline. Our results emphasize the importance of improving metabolic health not only in women of reproductive age, but also in potential fathers, in order to reduce the negative impacts of diabetes on subsequent generations.

[Impact of oncological treatment on human reproduction]
Infertility is one of the most common permanent implications of oncology treatment of patients in reproductive age. The aim of this paper is to summarize current knowledge about the impact of basic modalities of oncology treatment on human reproduction. The authors describe the influence of chemotherapy, radiotherapy and pelvic surgery on the reproductive functions of men and women. Both chemotherapy and radiotherapy diminish the ovarian reserve of follicles, which is the main determining factor of premature ovarian failure. Modern markers of ovarian reserves are introduced, which in common clinical practice can effectively help to evaluate the risk of irreversible damage to the gonadal cells done by oncological disease or its curative treatment. If there is a good chance to permanently cure malignant disease in an oncological patient of fertile age, it is advisable to consider new modern techniques of reproductive protection in cooperation with reproductive medicine specialists.

Modern era brought new diagnostic and therapeutic methods to endocrinology and changed the approach to many diseases and developmental disorders. Explosion of new findings brought about the possibility of examinations on subcellular level. Possibility to study structure and function of various genes is not any more the futurology. However, still in medicine romain a roas which are considered as less important. It is usually assumed that questions of fertility will be dealt by the specialist for adults. We suppose that the given problems should be well advised by an interdisciplinary co-operating team in the paediatric patients already. However, it should be recognised that some reproduction disorders have their origin in the early age. The aim of this paper is to give an overview on endocrine disorders in relation to reproduction impairments and to outline possibilities of co-operation between different specialist treating patients from childhood trough adulthood.
