I just (out of curiosity) looked up the term for a sperm bank in Chinese it would be Jingzi Yinghang. Yinghang=bank. The character jing for Jingzi on its own has some lovely definitions;

refined, picked, choice, excellent, perfect, smaller quantity and better quality (nice one), smart, clever, able, extract, essence.

I fink the Chinese have got it just about right. Must imply the ladies only get the best.....now I shall go and hide behind the sofa.
