Sleep Duration Is Associated With Testis Size in Healthy Young Men

Conclusions:There is a positive linear and a possible inverse U-shaped relationship between sleep duration and testis volume. Longitudinal or interventional studies manipulating sleep are required to better define causality, and ultimately to establish how much sleep is needed to maximize male reproductive potential.Clinical Trial Registration:Title: Hormonal Mechanisms of Sleep Restriction, Registry: ClinicalTrials.gov, Identifier: NCT02256865, URL:https://clinicaltrials.gov/ct2/show/NCT02256865Citation:Zhang W, Piotrowska K, Chavoshan B, Wallace J, Liu PY.
