Sleep is a physiological process that has important effects in improving physical anf mental functions. This complex physiological process, which covers a third of human life, has an important role in the healthty functioning of many systems such as circulation, respiration, musculoskeletal and central nervous system. It is an important event that affects the health of individuals as well as their quality of life. The quality of sleep is that individuals feel good mentally and physically. Sleep quality is affected by many factors such as presence of chronic disease, stress, environmental factors, economic situation, work and social life. Especially psychological stress and sleep problems have a bidirectional relationship with each other. While stress factors affect sleep quality, low sleep quality can worsen psychological symptoms. Studies have shown that sleep problems occur during the diagnosis and treatmetn of infertility. Due to the psychological problems and stress brought about by this process, problems such as shortening of sleep time, decreasing sleep efficiency and frequent sleep splitting occur. However, although studies have addressed somatic symptoms and psychological prolems in infertile inviduals, sleep problems have not been adequately studied. The aim of this review is to examine the effects of the diagnosis and treatment process on sleep quality in infertile individuals and to increase the awareness of nurses and other health professionals working in infertility units.
