Stimulated Stages of Penile Erection in an Edible Rodent

What’s up with the agouti [pictured here, in a San Diego Zoo photo]? Three proven males show what, according to this new study:

Anatomical Stages of Penile Erection in the Agouti (Dasyprocta leporina) Induced by Electro-Ejaculation,” W.M. Mollineau, T. Sampson, A.O. Adogwa and G.W. Garcia, Anatomia Histologia Embyologia, vol. 41, 2012, pp. 392-4. The authors, at the The University of the West Indies, St Augustine, Trinidad and Tobago, report:

“The reproductive system of the male agouti (Dasyprocta leporina), a Neo-Tropical edible rodent, is documented in only a few publications…. The objective of this study was to describe the various anatomical features of the agouti penis occurring during penile erection induced by electro-ejaculation…. Three proven male agoutis were stimulated by electroejaculation during this study…

The photo above is from an earlier publication by three of the same authors:  “A preliminary technique for electro-ejaculation of agouti (Dasyprocta leporina)“, W.M. Mollineau, A.O. Adogwa, G.W. Garcia, Animal Reproduction Science, vol. 108, nos. 1–2, October 2008, pp. 92–7.
