Cycling and sperm morphology/infertility

I wrote a while ago about low T and possible relationship with infertility,
It was suggested to get a sperm test so here it is.

I have plenty of swimmers, but they aren’t the most mobile and they look a bit funny.

There seems to be some research that cycling volume impacts on morphology the most -

Mine was 3% pretty dam low.

Firstly, has anyone had these tests, found to have low numbers of good sperm and improved it with time off the bike?

On the flip note, has anyone been found to have low morphology and had no issues with fertility.

The above results come after 1 month off the bike, I promised the wife I would take 2, but this result could mean indefinite if things don’t work out!

I think that unless you are riding 6-8+ hrs per day that no meaningful effects have been noted.

Same goes for people who drive vehicles for a living.

I’m not sure that’s right based on the above study

In addition I’m fairly certain I have a small varicocele which is related to trauma in the nethers = cycling

It is not about the size… :wink:

Before kid 1 my count was ok but motility was low, they told me to start taking vitamin C, boom, kid immediately after. I didn’t cut back on cycling but wasn’t spending a ton of time in the saddle anyway.

Hello TimBryan and All,

What is relationship between sperm, testosterone, and endurance levels?

What is relationship between sperm, testosterone, and endurance levels?

What if you also added owning a Subaru into that mix?

Thanks, but not totally sure what that paper has to do with cycling? Also a fair amount of rubbish in that article, not sure I trust anything from Charles Poliquin!
On the flip side I have found some info about pesticides reducing morphology selectively, so maybe my green salad addiction is to blame!

Hello TriBryan and All,

Playing librarian here … as your doctor or clinic should have your best advice … of course.

In my previous post I was suggesting that you are probably on the right track taking some time off … from endurance (bicycle) training … to improve your sperm count … using the evidence that links endurance training and lowered testosterone levels … and with sperm levels further linked to testosterone and LH production.

(It is interesting to note that testosterone supplementation suppresses sperm production … so that does not seem a likely solution.)

Note in the study below the 60% drop in LH (precursor for sperm production) with four months of endurance training.

https://www.ncbi.nlm.nih.gov/pubmed/14674205

Excerpt:

“There was a significant decrease in all parameters measured after four months of endurance training. Decreases in body composition parameters were 54% in percent body fat, 6% in fat free mass, and 13% in body mass index. **There was a dramatic 58% drop in testosterone, 60% drop in LH and 15% drop in FSH after four months of endurance training.” **

Good luck!

Thanks for the Input Neal, I really appreciate it.

Does anyone have any experience of getting test results like this and the result being all ok?
