Sleep, psychological distress, and clinical pregnancy outcome in women and their partners undergoing in vitro or intracytoplasmic sperm injection fertility treatment.

Objectives: To explore the prevalence of poor sleep quality in couples undergoing fertility treatment and study possible associations.

Participants: 163 women and 132 partners receiving in vitro (IVF) or intracytoplasmic sperm injection (ICSI) fertility treatment.

Setting: Three public Danish fertility clinics.

Associations of bedtime, sleep duration, and sleep quality with semen quality in males seeking fertility treatment: a preliminary study.

Background: Poor sleep has been linked to a number of adverse health outcomes. Recent studies suggest that late bedtimes, short or long sleep durations, and poor sleep quality may impair semen quality. No study has previously explored all three factors in relation to semen quality.
