Our goal is to assess the depth of penile penetration during copulation and to explore which anatomical landmarks are in contact and where. The penises of adult males will be inflated with saline and inserted into the vaginas of adult females from the same species. The penises will be inserted as deep as possible to simulate copulation.
After the genitals are CT scanned together, they will be dissected to identify anatomical landmarks (Orbach et al. 2016), which will then be located on the CT scan images. The depth of penile penetration and the points of contact between the male and female genitalia will be identified and compared across species to explore broad patterns of genital coevolution.
So, maybe you’d like to help support some cool marine reproductive biology, or maybe your tastes, like those of Christian Grey, are singular. Either way, visit the project site for some inspiring science and horrifying images.
