If you are cycling around Copenhagen, this new bike will sure catch your    attention. Well, I am talking about the Sperm Bullitt, a bike  designed   like a sperm with a cooling storage system to deliver the  sperm  samples.  The bike was made for Nordisk Cryobank (European Sperm  Bank),   one of Europe’s leading sperm banks, in their effort to find    C02-friendly way of transport to deliver their sperm samples to the    fertility clinics around Copenhagen.
