Introduction. Suicide has always meant a moment of different significance for philosophers, physicians, sociologist, and psychologists, etc., but also for the various religions or even for ordinary people. Some have accepted it as a form of liberating the man from the burden of life or the manifestation of the spirit of freedom, where other condemned and cursed the person who makes such an extreme act.  Aim of the study. Study and elucidation of socio-economic, medical and bioethical aspects in the case of suicidal tendencies, assessment of the specificity of cases of suicide. Materials and methods. In the scientific paper were used as study material the statistical data of the National Bureau of Statistics of RM, of the Center for Health Management, reports from medical institutions and medical documentation. There were used systemic, statistical, and bioethical methods.    Results. An estimated 800,000 people have committed suicide annually throughout the world, but the attempts are 20 times more. Bioethics sees suicide as a form of aggression as a reflection of a social pathological state.   Conclusions. Nowadays, there are a number of theories that have attempted to explain the suicidal phenomenon, but all together, even individually, they haven’t been able to fully get into the essence of this social phenomenon. It is quite difficult to find those things that defy the laws of nature, and that is because the suicidal act cancels out the instinct of survival with which we are born with and which is engraved in our genes. However, suicide is an extremely present and current phenomenon which, as days pass, extends like an epidemic among the population.
