dc.description.abstractObjective: The effect of sleep-related variables on the reproductive system has garnered attention in recent years. One of the mediators that reportedly plays an important role in the relationship between sleep disorders and the reproductive system is a disruption of the circadian rhythm. The aim of curent study is to investigate the effect of chronotype on morning semen quality.Study Design: Three-hundred and fourteen patients who applied to the infertility clinic were included in the study. The patients filled a socio-demographic data form. The Pittsburg Sleep Quality Index (PSQI) was used to evaluate the sleep quality while the chronotypes of the patients were evaluated with the Morningness -Eveningness-Questionnaire (MEQ). Semen analyses and biochemical analysis for testosterone serum plasma level of all patients were performed.Results: Twenty-one patients were assigned as evening, 187 patients were assigned as intermediate, and 106 were assigned as morning chronotype. No statistically significant difference was identified in the comparison of the mean MEQ scores between patients with low and normal sperm concentrations(p = 0.884). A correlation analysis indicated the presence of a significant positive correlation between normal morphology and MEQ scores (r = 0.13, p < 0.05) and a negative corelation between the hours spent in bed and sperm concentration (r = -0.13, p < 0.05). A general linear model created with independent variables suggested that the presence of varicocele and MEQ scores had a significant effect on normal morphology.Conclusion: The results of present study support that evening type could negatively affect sperm morphology; additionally, the time spent in bed also negatively affected sperm concentration.en_US
