cwnl: Deep-Voiced Men Don’t Have ‘Macho’ Sperm Side Thought: Well this isn’t creepy at all, just as I finished off a rant on masculinity then scoured off to find some general science articles for you guys I find this article conveniently waiting to be blogged about. In terms of evolution and passing on favorable traits, is having more masculinity even important or useful for that matter? A low-pitched voice in a man is associated with a litany of masculine traits: dominance, strength, greater physical size, more attractiveness to women, and so on. But new research strikes one trait off that list: virility. An Australian study looked at male voice pitch, women’s perceptions of it, and semen quality. Their first finding was no surprise: Women like deep voices and consider them masculine. But contrary to expectations, they also found that these men aren’t better off in the semen department. In fact, by one measure of sperm quality — sperm concentration in ejaculate — men with the attractive voices appeared to have a disadvantage. This is a surprise because females, both humans and of other species, are believed to glean information about male virility through secondary sexual traits, such as facial hair and muscle mass in humans and other traits in other animals, such as colorful plumage in birds. In the case of voice pitch, the researchers from the University of Western Australia suggest there may be a trade-off at work. In other words, traits associated with dominance and attractiveness, such as physical strength or a deep voice, may come at the cost of reduced sperm quality, they write in a study published Dec. 22 in the journal PLoS ONE. For instance, higher testosterone levels are associated with a deeper voice, more masculine features, more dominant behavior and success in obtaining sexual partners. Although testosterone plays an important role in the formation of sperm, however, high levels of it can actually impair sperm production, they write.

The next time you want to put a poem on your iffy Photoshop job of a galaxy or nebula, remember it took someone hours of editing just like this to make the original. It’s like salting your food at a Michelin restaurant.

So, I dunno, at least make it some T.S. Eliot or something worth all that effort.

samspratt: Wolverine- practice painting by Sam Spratt I often get flack for rarely painting the male form. I admit, I’m biased towards the fairer sex, but… I hear you, so one of my goals of 2012 is to even that out a bit. Here’s my warm-up.
