Semen, centrifuges and a personal journey in male fertility
In August 2012, I came into a neon-pink shot glass. Nine months later, a baby was born. I'd never planned on having a child of my own -- and to be clear, I still don't -- but when two of my best friends started looking for a donor, I jumped on the opportunity. For those of us who can't have children with our partners through good old-fashioned sex, the path to pregnancy is complicated and expensive. After careful consideration, my friends decided on what's commonly referred to as the Turkey Baster Method. I would masturbate into a sterile collection cup and pass the resulting semen to my friend who would draw it into a syringe and deliver it to his wife. She would then plunge it into her vagina.
Sperm gene same as it was 600 million years ago, miraculously still in fashion
We've had a thing for sperm ever since Look Who's Talking broadened our appreciation for the reproductive arts, and now scientists at Northwestern's Feinberg School of Medicine have discovered a wealth of new information about the world's most adored swimmers. Believe it or not, we're now left thinking that they're even more hardcore. Yes, they've been rocking the exact same makeup -- called the Boule gene -- since the dawn of evolution. But as it turns out, that gene is also shared across a huge swath of organisms from humans to fish to fruit flies, and it's only ever used in sperm. This bodes interestingly for the future of reproductive sciences; researchers removed the Boule gene from mice and found that, while otherwise completely normal, they didn't produce sperm. We can almost feel that Gucci case for the male contraceptive pill in our man-purses now. [Photo courtesy of aSIMULAtor]
Cellphones are dangerous/not dangerous, hodgepodge edition
Lest the danger (or non-danger) of cellphone use stray too far from your mind, here's a trio of recent studies to get the juices flowing again. First, the best news: an Australian researcher has come up with a five-point ranking system to lay out the likelihood of getting cancer from partaking in various substances and activities, and if that system has any basis in reality, cellphones are "unlikely" to cause cancer -- so take it for what you will. The second study, thrown down by the Cleveland Clinic, showed a significant decrease in sperm "quality" (as determined by a number of stats) as average daily cellphone usage increased; not necessarily a short-term problem for the users themselves, but a finding their future children (or lack thereof) might take issue with. The third study brings more bad news, showing that human skin exposed to cellphone radiation altered the cells' protein expression, a potential (though by no means definitive) precursor to cancer. As always, your mileage -- and your body's mileage -- may vary.[Via textually.org]Read - "Cell Phones No Cancer Risk, Study Says"Read - "Effect of cell phone usage on semen analysis in men attending infertility clinic: an observational study" [Warning: PDF link]Read - "Mobile phone radiation might alter protein expression in human skin"
