Temperature affects how much sperm a man makes, so there's been speculation that the freedom offered by a kilt can increase production. Turns out that that at least could be right: a new metastudy says wearing a kilt "likely produces an ideal physiological scrotal environment, which in turn helps maintain normal scrotal temperature, which is known to be beneficial for robust spermatogenesis and good sperm quality."
The study (PDF), published in the Scottish Medical Journal, reviewed the literature on the link between scrotal temperature and reproduction. We know sperm fares better in lower temperatures, and some researchers have suggested that restrictive clothing could negatively affect sperm production. Enter: the kilt, which author Erwin J.O. Kompanje describes thusly: "The Scottish kilt is a male garment that resembles (but is not!) a knee-length, pleated skirt."
The author hypothesizes that, based on past findings about temperature and sperm production, a kilt, specifically one worn in the undergarment-free "regimental" style, would be an ideal environment for sperm production. Kompanje searched through related research, focusing on statistics in Scotland and noting along the way that 70 percent of kilt-wearers choose to go regimental. Kilts (at least in Scotland or other countries where they're more commonly worn) might also be psychologically valuable, increasing feelings of masculinity when worn. Kompanje goes so far as to write that a downturn in Scottish fertility is correlated with the frequency of kilts being worn, although he admits it's still somewhat speculative until a randomized trial happens. Gentlemen, put on your kilts for science.
Only when I'm Piping.
Sorry but this info has been around for 40 years. It's well know that freeing up the boys helps sperm production.
I don't think the human race is having a sperm production problem.
Battery powered heated underwear for everyone!
Auroria, a lot of the population predictions have been wrong for a long time because they assume that our growth will remain the same under changing conditions. As cultures become more prosperous, they have fewer children. There are many countries that have NEGATIVE population growth, meaning more people are dying than are being born. Saying that we have any idea how technological and societal changes will affect population growth 100 years from now is silly.
My prediction is the world population will be down to 5.2107 billion by January 2150. The war between China and the Republic of Texas had some serious casualties, and a lot of people immigrated to Mars to escape the ozone pollution caused by all the electric cars.
"Cross dressing could make your sperm stronger"
Actually killerT, cross-dressers push their testes back into their abdominal cavity and then use duct tape to tie the rest back (which is actually effective in giving them the appearance of labia). Too much warmth is what they are implying is the cause of low production, so they're suggesting to avoid that by letting them hang free.
This just in: water is wet! Balloons float! Trickle-down doesn't work!
Who on earth green-lighted this study? Captain Obvious?
Always defer to facts rather than philosophy.
Cute comment and to the point.
