A 321-page study published last week shows sperm counts in men have been falling for the last 40 years. There is a link that smoking, obesity and stress may be the cause of male infertility, but there’s no conclusive evidence yet.
Other causes are increases in scrotal temperature. It could cause defection of sperm that is not effective in penetrating the egg, lowering the likelihood of becoming pregnant. Hot tub use and tight clothes can also be contributing factors. But also, laptop use on your lap can increase scrotal temperature. Using a laptop desk with internal cooling measures can help regulate the temperature of your laptop, and push heat away from your body, thus protecting your scrotum.
The urologist Yefin Sheykin, MD, an associate professor of urology at Stony Brook University Hospital School of Medicine, published a study in 2005 and 2011 that proves laptop use does increase scrotum temperature, causing it to rise significantly in men using laptop computers. Using laptops in the laptop position— i.e., legs crossed with laptop on top— may impact fertility. It hasn’t been proven definitively that laptop use in men increases infertility, but to be safe: it is good to use a laptop desk.
I personally know Dr. Sheykin. He’s my personal urologist; I was a patient of his on two occasions when I got kidney stones from drinking whey protein powder drinks laced with calcium. Each serving contained 100 percent of the U.S. RDA (United States recommended daily allowance.) This is equivalent to 1,000 mg of elemental calcium per serving! I was taking one to two of these shakes per day!
Caution: please read the labels and don’t take calcium-fortified whey protein if you’re at risk of kidney stones! Kidney stones are not fun and extremely painful!
Also, it is recommended that men and women should get their calcium from their diet and not from supplements. Recent evidence in peer-reviewed journals has shown an increased risk of cardiovascular disease and heart attacks in people who take dietary supplements of calcium, but not from calcium naturally obtained in their diet!
I can’t believe that I didn’t read the label before drinking those whey protein calcium-fortified shakes!
