'Movember' is also known as No-Shave November, encouraging men to grow moustaches and beards during November for increased public awareness of men's health issues.
"Doc Johnson is a proud supporter of The Movember Foundation and Prostate & Testicular Cancer Awareness Month," reads their My Motivation page on the Movember website.
The Movember Foundation hopes to shed light on issues ranging from depression to prostate cancer. Their goal is to thereby "change the face of men's health," by increasing early cancer diagnoses and treatments, as well as fundraising for prostate cancer research.
The non-profit group also promotes annual check-ups and greater focus on family history of cancer, to make preventable deaths occur less frequently.
"We moustache you a question... but we're shaving it for later," tweeted the Doc Johnson company, offering images of a mustachioed penis dildo dressed like a gentleman.
