There's this city in Denmark called Arhus.

The middle of the fall here in Denmark seems to be a pleasant little Danish college town.

And I'm here to visit Cryos International.

Cryos International is a sperm bank.

Getting close here.

They ship Frozen's sperm all over the world to over 100 countries.

And a lot of the action happens on the 5th floor of this kind of nondescript red brick building.

Is this the main office up here?

The headquarters. That's where I got to go.

And right when you walk in, there's a bowl of sky blue condoms right there. They say Cryos.

It's marketing, but also they want their donors to practice safe sex.

Next to the waiting room, there are these rooms called donor cabins with touchscreen computers and erotic magazines.

A little red light comes on when the donor cabin is occupied.

And that's where I meet Nicholas Finarope.

Have you spent a lot of time in this room?

No, no, no. They don't like it when you stay too long.

That's it, times up. No, it hasn't happened.

Never really never knock.

Are you donating today?

I already did.
