Embryonic koro in birds

Cocks (almost) don't have a penis, a trait common to 97% of bird species, but they can grow one when the expression of the Bmp4 gene is prevented. The expression of this gene causes the percursor of the phallus in the chick embryo to undergo apoptosis (cell death) and Bmp genes are also involved in 3 other bird traits: feather development, toothlessness and beak shape. In penis-less bird species, copulation requires a sex maneuver nicknamed the cloacal kiss (in French) which requires a full cooperation of the female (3 min of tender parrot sex). In species where males have a penis, like ducks, females are less lucky: the coevolution of the rather convoluted morphology of male and female genitalia has been hypothezised to occur through sexual conflict [many previouslies]. The evolutionary mechanisms that drove phallus reduction in most birds species are still unknown.

Phallological Museum

The Icelanding Phallological Museum. A museum dedicated to the male sexual organ, with an online gallery of phalluses of many species.
Lingam Gnosis is the 'ancient art of penis reading' - like palmistry, only with penises, which can be classified into alchemical earth, fire, water and air types.
Foreskin.org is an educational site about the male foreskin (with photographs and articles).
(Needless to say, probably not suitable for work).

Harvard Penis

Did you hear the one about the Harvard girls and the large snow phallus? Oh, and here's the response featuring the memorable line: "it means that we, as women, must be subject to erect penises whether we like it or not."
