ahh apparently they're not 11 sperms in the Cologne coat of arms, they're tears..
'The eleven tears are a reminder of Cologne's patron, Saint Ursula, a Britannic princess, and her legendary 11,000 virgin companions who were supposedly martyred by Attila the Hun at Cologne for their Christian faith in 383. The entourage of Ursula and the number of victims was significantly smaller; according to one source, the original legend referred to only eleven companions and the number was later inflated by relic traders'
I still like to think of them as sperms though
