Original Article

The authors are retracting this article because an error in the reported methodology of this study was found when a follow up investigation of gorilla oxytocin was undertaken. The methods section of this article reports that an extraction step was used in preparing the urine and saliva samples for assay; however, a critical step in the extraction process was mistakenly omitted. The data reported here thus represent a validation of unextracted samples and not of extracted samples. Additional analysis is currently being conducted to understand how the unextracted samples compare to extracted samples and we will submit a new manuscript for review when this has been completed. All authors agree with this retraction.
