Some scientists at the University of Zurich have published a fascinating piece of research, entitled ‘What is a good looking penis?’.

Women of varying ages were shown a variety of penises, and asked to rank them according to attractiveness, and whether or not they appeared ‘normal’.

Boys, take note. Girls, if ever you need back up when approaching the delicate matter of asking your fella to trim the forest ‘down there’, this is for you.

Thanks Mashable for bringing it to our attention.

Here is how the rankings stood, from most to least important aspects of a penis.

1. Importance of general cosmetic appearance
2. Importance of appearance of pubic hair
3. Importance of penile skin
4. Importance of penile girth
5. Importance of shape of glans
6. Importance of penile length
7. Importance of appearance of scrotum
8. Importance of position and shape of meatus (urethra)

If you managed not to retch at the word ‘meatus’, you’re doing better than me.
