Shelton's comments attracted media publicity, but were heavily criticized on factual and methodological grounds by medical historians, who pointed out that in 1761, Peter Camper had indicated that figures "were not all from real life", and very likely other methods than murder were available to obtain bodies of recently deceased pregnant women at that time. Hunter also provided case histories for at least four of the subjects illustrated in "The Anatomy of the Gravid Uterus Exhibited in Figures", published in 1774. A recent review of Hunter's sources of anatomical specimens was published in 2015.
