Correction to: International Journal of Impotence Research
10.1038/s41443-019-0161-8
In the published article an error occurred in the definition of CGMP. The correct definition should be “cyclic guanosine monophosphate,” not “current Good Manufacture Practices” as reported.
The authors apologize for the error and any confusion it may have caused.
This has been corrected in both the PDF and HTML versions of the article.
