Herpes viruses and male infertility - Is there any relationship?
Voprosy virusologii 09/2013; 58(3):4-9.
A relationship between the herpesviral infections and male reproductive health is of importance to both theoretical and practical medicine. The review contains the data on the frequency of herpes virus identification in sperm, the effect of the viruses on structure and function of male germ cells, potential vertical transmission of the herpes viruses with male gametes, and experimental models of study the effects of herpes viruses on spermatogenesis. From the analysis of these data it can be concluded that: 1) identification of herpes virus in sperm is associated with reduced fertility; 2) herpes simplex virus has a negative effect on spermatogenesis, which manifests itself in a decreased proliferative activity of spermatogonia, meiosis block and enhanced apoptosis of germ cells; 3) herpes viruses can be found intracellularly in male gametes; and 4) the analysis of the markers of widespread herpes viruses (HSV, CMV) should be included in examination of men attending infertility clinics.

ABSTRACT: In recent years the significance of knowledge of immune mechanisms of various pathological conditions is growing, since it is related to the survival peculiarities of modern human. Acute diseases are frequently protracted, the number of chronic conditions increasing. The principal tasks of human immune system study is to determine an impaired component of immunity system, make the prognosis of a chronic character of the disease, and assess the provided treatment efficiency. Virus immunology is progressing rapidly. However, there are still many incomprehensible mechanisms of interaction between a human organism and viruses; some functions of many virus proteins enabling viruses to escape immune surveillance are understudied. Such studies will enable to comprehend significantly the pathogenesis of virus infections, and therefore develop new forms of treatment and prevention. The review presents current views on immune response formation in herpetic infection, the interaction mechanisms of a virus and a macroorganism, the main lines of research in a clinical picture, diagnosis and management of the pathology. © 2014 Nizhny Novgorod State Medical Academy.
