How Sleep Duration Affects Sperm Quality
It is well known that lifestyle factors such as smoking, poor diet and recreational drug use affect sperm quality. What isn't widely known is how sleep habits can affect sperm health. However, this study set out to determine exactly how the duration of sleep and the quality of sleep affects sperm health. 1487 men aged between 22 and 45 years were recruited for the study. An initial sperm assessment was performed to check eligibility for the study. The participants were required to have normal sperm health prior to the study and meet the following criteria:
- Sperm count of more than 60 million per ml
- Progressive motility higher than 60%
- Normal morphology higher than 30%
