If you've got a low sperm count, it may be down to the fact that you're so good looking... New research suggests that attractive males don't produce as many sperm as their less handsome counterparts. Apparently this is part of a pattern seen in some animal species where males who attract more females produce fewer sperm each time they mate. The males who aren't as popular with women need to produce more sperm each time they ejaculate in order to maximise their chances of reproducing, as they will get to mate less frequently.
The research is part of a study from researchers at University College London and the University of Oxford, and you can find out more at www.ucl.ac.uk
