Adverse effects of circadian desynchrony on the male reproductive system: an epidemiological and experimental study.

ABSTRACT:

Study question

Is circadian desynchrony a risk factor of male reproductive damage in semen parameters and/or reproductive hormones?

Summary answer

Circadian desynchrony correlates with decrease of sperm count, which was improved when circadian desynchrony was attenuated.

What is known already

Circadian desynchrony caused by work (shift work) and non-work-related reasons is prevalent worldwide and has been found to be associated with decreased female fertility, but whether it harms male reproductive health is unclear.

Study design, size, duration

A hybrid research was conducted. (i) A cross-sectional study of 1346 Chinese men in 2007 was used to analyze the association between semen/hormone biomarkers and work-related circadian desynchrony, which was divided int
