…which requires a sperm count from every new recruit?
The article says only 5000 Danish recruits provided semen over 15 years. So it sounds like it was a voluntary study in which they asked every 18-year-old going in for their physical.
Cockfighting?
A seminal bit of research, no doubt!
Indeed, many countries with a draft use it as a chance to perform census statistics on the population, such as measuring the general level of health.
Haven’t got a comment regarding the sperm thingy, but find it kind of amusing that the Danish Army, from one of the flattest countries on earth, is currently fighting in the mountain crags of Afghanistan. So my answer to the initial part of the question would be - “on unfamiliar ground.”
