Mathematicians? What are they doing that would cause birth defects? Working on computers or something? Toxic pencils? Hmm...I knew there was a reason I didn't major in math. It turns out it really isn't good for you...hehe.

All I can say is it took long enough. How many defects were there that could have been prevented a long time ago?

Duh! Your environment causes birth defects. Men living in air polluted environments, such as harlem, are advised to move out to cleaner air and wait 90 days before conceiving. It takes 90 days for sperm to rotate out of system

"The researchers classified the jobs into 63 groups, based on their assumed exposure to chemicals or other potential hazards"....doesn't that mean that they already decided that chemicals are the cause, and then guessed about exposure? Chemicals might very well be the cause, but should they try to document exposure rather than assume it? Does the exposure necessarily happen in the work place? What if these guys are getting exposed somewhere else in their free time or at home? I am no epidemiologist, but this seems like a weak study.

I read awhile back that that white out stuff they used to use back in the day was highly toxic. Anybody remember that stuff?

What a dumb study. What are men supposed to do? Take months of leave from work and go live in the woods and eat nuts and berries before trying to conceive a child, which can be no easy task for some. Ridiculous weak and unnecessary study that can not be concluded without a ton of more studies and waste of money. No man is going to take off work before conceiving a child and all the financial responsibilities that come with it. Just flippin stupid.

Seems to me like this article is riddled with defects...

I wonder why this article makes no effort to explain why mathematicians, physicists, computer scientists and office and administration support workers are at risk? That seems to me like the obvious question anyone would have after reading this. Even just to say they don't know would be better than ignoring the question altogether.

Most of the others make sense on some level but what is the risk source for these jobs? Maybe if you sit in front of a computer 40-50 hrs a week, maybe there are fumes from the plastics being released or something? Hmm.

both of my son's dad's kids (one with me one with his ex) had near sightedness in the left eye so it has to be him whose the contributing factor and the fact that he's a welder being exposed to dft chemicals and stuff.

So you tell us that certain jobs will lead to birth defects, yet you don't tell us anything else. You don't even post a link to the source.

What kind of article is this? A little knowledge is a dangerous thing.

This study doesn't pass the smell test. The list of jobs associated with multiple child birth defects pretty much covers the entire spectrum of jobs. Sounds like a very flawed study.

Husband worked with computers our whole marriage. 4 kids, no birth defects. Now I feel like we won the lottery!

although i have a lot of chores i try painstakingly to spare some of my time for msnbc actualities since iam quite sure that these actualities make me very happy,iam very well convinced with msnbc great efforts that made it in such a paramount position,hoping more success,bye,ahmed abdo.

That's a pretty large list of common professions; so basically if a future dad has a job, his child is at an increased risk for birth defects. I think the researchers in this case have been around chemicals too long.
