In a nice example of the self-correcting nature of science, the editor of the International Journal of Impotence Research - a Springer Nature title - has retracted a paper despite the disagreement of all the authors, because he realised it was a homeopathy promotion with no basis in science.
The paper had slipped past the peer-review process but, when examined in detail fell far short of the standard science normally expects of medical research. It had purported to show that a drug, Impanza, manufactured by OOO NPF Materia Medica Holding, of Moscow, gave rats an enlarged penis and might therefore be useful in treating erectile dysfunction in humans. There were also claims that it increased libido and enhanced intercourse satisfaction!
