The results of the semen analyses conducted at the fertility clinics were self-reported and categorised as normal or reduced. Early bedtime (< 10:30 PM) was more often associated with normal semen quality compared with both regular (10:30 PM-11:29 PM) and late (≥11:30 PM) bedtime (OR: 2.75, 95%CI: 1.1-7.1, p = 0.04 and OR: 3.97, 95%CI: 1.2-13.5, p = 0.03). Conventional sleep duration (7.5-7.99 h) was more often associated with normal semen quality than both short (7.0-7.49 h) and very short (< 7.0 h) sleep duration (OR: 1.36, 95% CI: 1.2-12.9, p = 0.03 and OR: 6.18, 95%CI: 1.6-24.2, p = 0.01). Although poor sleep quality was associated with reduced semen quality in the descriptive statistics (p = 0.04), no differences were found between optimal (PSQI ≤6) and either borderline (PSQI 7-8) or poor (PSQI ≥9) sleep quality (OR: 1.19, 95%CI: 0.4-3.4, p = 0.75 and OR: 2.43, 95%CI: 0.8-7.1, p = 0.11) in multivariate regression models.
