The Huffington Post reports on some research that poor sleep could affect sperm production and quality. 

Going to bed after midnight and sleeping too much was also found to affect sperm quality.

Semen motility (how well it moves) was lower in short sleepers, compared to the average and long sleepers. They were also found to have a greater incidence of ASA.

The scientists concluded that “short and long sleep durations and late bedtime were associated with impaired sperm health”.

Professor Geeta Nargund, medical director of Create Fertility, told HuffPost UK that the study confirms the findings of previous studies showing an association between sleep disturbances and sperm quality in men.

“However, we need further studies to understand the mechanistic explanations and to assess whether sperm quality improves after interventions to restore sleeping patterns,” she added.
