Σύνοψη	IVF Embryo Grading is a standardized morphological assessment system for evaluating the quality and viability of embryos in assisted reproductive technology. First formalized by Gardner and colleagues in 1999, it uses microscopic examination to score embryos across multiple criteria, enabling clinicians to select the most viable embryos for transfer and improve pregnancy outcomes.	Polysomnography (PSG) is a comprehensive multi-channel physiological recording method that simultaneously records brain electrical activity, eye movements, muscle tone, respiratory effort, oxygen saturation, heart rate, and limb movements during sleep. First systematized by Rechtschaffen and Kales in 1968, polysomnography is the gold standard for diagnosing sleep disorders, characterizing sleep architecture, and assessing the quality and organization of sleep in humans and increasingly in veterinary species.
