In a study published in the medical journal Human Reproduction, researchers analyzed many different lifestyle factors that could possibly have an impact on male infertility. The study was the largest of its kind, examining how habits such as smoking and drinking alcohol affected men’s sperm size and shape – also known as sperm morphology.

According to the researchers, marijuana use was the only habit they studied to be strongly associated with abnormal sperm morphology.

Watch out Washington and Colorado. Survival of the fittest

i didn't read the link but I would assume that eating genetically modified foods would eventually play a role. Also eating foods covered with pesticides and not washed correctly etc etc. Also, we eat way more salt and sugar than is good for us and I'm sure over generations that HAS to impact us somehow.

so what you're saying is that there is no such thing as evolution, only mutation ~ i agree

No no. Now there is mutation for sure but we still evolve but not as we used to. Now we are forcing the changes instead of letting nature take it's course.

Actually Cuda, that was discovered back in the 70's. Wonder why it's "big news" now. oh well.

Washington, Colorado

I blame it on climate change.

I think it will be a good experiment. That's the only way we'll know what happens to people when the populations of 2 entire states are constantly zoned out on a particular drug. An actual long term research experiment on such a large group of people would be deemed unethical.

All joking aside, I think that sperm morphology (which can be affected by a lot of different medications) is orthogonal to genetic mutations.

So maybe marijuana use will be self correcting in the affected populations. Less viable sperm, lower rates of reproduction, less users as time passes.

That, and the greatest marker of fertility (by a huge margin) is testicle size.

All I can say about it that my girlfriend loves when I eat pineapple shortly before sex

Also, I'm guess this Fox News article is the source:

Here's an older story from 2003 and not Fox News. Apparently, men's sperm go all hyperactive on THC, then burn out their motors well before they get to home base. But it gets better. Women who smoke have the THC show up in their vaginal fluids. So once the sperm gets "deposited", they come into contact with the already present THC and never make it to their destination for the same reason.

Stoned sperm. Never imagined that.

Pot: the male birth control pill!

yet, all of the lifetime smokers i've ever known had kids, some lots of them, none of them is childless. Go figure.

And here I thought my massive nuts was a bad thing...

quit whining, I'll let you borrow my wheelbarrow.

Kinda counter intuitive. You'd think a stoner's sperm would be slower and more lazy. I'd have guessed a tweaker's sperm to much faster and quicker to burn out. Go figure.

I'm not whining. I'm bragging.
