I recall reading an article, many years ago, in the New Scientist concerning a study into the effect of the lunar cycle on men. It was suggested that some men showed a physical response, such as a change in the rate of beard growth.
I don't know if it was part of the NS article, but this has obvious links with werewolf stories.
I have a kind of wish for this to be true. It seems feasible that some response to the moon should exist in men as well as women, given our evolution in the presence of that near neighbour.
Edit, further information:
An article on the Biology Online website cites research into lunar influence on animals and plants. This does not specifically mention the influence on men but, more generally, animals.
