Are you going to bed too late?

Could your sleep patterns be affecting your sperm count? New research from China has found that going to bed after midnight along with sleeping much less or much more than average seems to have an impact on sperm.

The research team looked at more than nine hundred men who had regular sleep patterns and divided them into groups who were all given different sleep durations and bedtimes. They then carried out semen analyses over a period of six months, and found that those who were having the shortest sleep had lower sperm counts and lower motility.  They also found that those who went to bed after midnight had lower sperm counts regardless of how long they then slept for.

So, if you are trying to conceive, it’s certainly worth ensuring you get to bed before midnight – and that you don’t get too little or too much sleep. You can find the full paper from the team at China’s Harbin Medical University, which was published in the Medical Science Monitor, here
