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 

E-cigarettes and your fertility

They are often thought to be the safer version of smoking – but new research has found that the flavourings used in e-cigarettes may contain toxic chemicals which can damage men’s sperm.

A team from University College London found that two of the most popular flavours put into e-cigarettes were particularly damaging to sperm – bubblegum and cinnamon were both found to affect male fertility.  You can read more details about their research, which was presented at the Fertility 2017 Conference earlier this month, here 

Why watching the Olympics doesn’t damage your sperm count…

120px-TV_highqualitySo the Daily Mail tells us that watching too much Olympic sport on TV  “could spell problems ahead” for men who want to become fathers. I am pleased to tell you that watching the Olympics is not going to make you infertile…

The report is based on research from Copenhagen University published in the American Journal of Epidemiology which found that healthy young men who had a “couch potato lifestyle” and watched more than 5 hours of TV a day had lower sperm counts than those who were more active.

It isn’t the first time that research has concluded that too much TV is bad for your fertility (see this report here with some common sense advice from Professor Allan Pacey) but this research discovered that sitting at a computer screen for the same amount of time didn’t have the same impact – it was thought that the men who watched TV were also likely to eat less healthily and take less exercise – which brings us back to the root of the problem with the point about watching the Olympics being bad for your sperm count.

The reality is that it’s a healthy lifestyle which makes a difference to your sperm – and to your general health and well-being. You don’t really need academic researchers to tell you that a man who spends entire days in front of the TV eating chips and drinking beer is less likely to be fertile than a man who watches masses of Olympics on TV but also eats healthily and enjoys getting out and about taking moderate exercise.
