For a Chinese hospital has come up with the ultimate measure of manliness by launching a contest to find its nation's strongest sperm.

Renai Hospital of Guangzhou, capital of southern China's Guangdong Province has launched the oddball challenge to find candidates over 18 years old to – ahem - come to the hospital to 'extract' their sperm.
