Abstract : <p>Coprophagia is defined in the 32nd edition of Dorland&#39;s Illustrated Medical Dictionary as &quot;ingestion of feces called also coprophagy&quot;. A classification scheme for coprophagy types in humans is presented in this review. Literature on coprophagy, and its affiliated keywords like coprophilia, scatolia and fecal bacteriotherapy, as indexed in the PubMed database and other commercial databases such as Science Direct, Wiley Online and Springer was studied. Two main frames of coprophagy are, intra-species coprography (ingestion of feces solely from Homo sapiens) and inter species coprography. (consumption of animal feces other than <em>H sapiens</em>). Intra-species coprophagy is further subdivided into two distinct types; (a) Autocoprophagy ingestion of self-produced feces, and (b) Allocoprophagy Either ingestion or trans- plantation of feces from other H sapiens individuals. Depending on the route of introduction of feces into the body, two sub categories are identified. Type 1 paraphilia oral ingestion of feces produced either by &#39;partners&#39; in consensual sex play or in a transaction between prostitute and customer. Type 2 Clinical treatment of transplantation of feces to patients suffering from Clostridia difficile infection is included in this type. As fecal medicines, inter species coprography prevails in the traditional Han Chinese medicine system and other traditional ethnic medicine systems of China. Most of the coprophagy literature published now, belongs to the category of &#39;autocoprophagy&#39; in this classification. But other categories also deserve recognition.</p>
