Forest plot summary of logistic regression analysis for the association between mental health status and semen parameters in individuals stratified by sleep duration. (A, B) The impact of depression on semen quality were analyzed in participants with sleep duration ≥ 7 hours (A) and < 7 hours (B). (C, D) Association between anxiety status and semen parameters in individuals with sleep duration ≥ 7 hours (C) and < 7 hours (D). PR, progressive rate; TSC, total sperm count. For each analysis, models are adjusted for age, body mass index, current smoking or alcohol-taking taking (yes, no), exercise (never, current occasional, current regular), occupational hazards exposure (yes, no), education level (high school or below, college, postgraduate), marital status (unmarried, married, remarried), time to bed (before 12 pm, after 12 pm), self-rated sleep quality (good, not good).
