What is Movember?

The Movember Foundation is committed to raising awareness and funding for men’s health issues. Their website is clear: “Our fathers, partners, brothers and friends face a health crisis that isn’t being talked about. Men are dying too young. We can’t afford to stay silent.”

As a result, the charity is focussed on some key areas that most affect the male population, and are least talked about: prostate cancer, testicular cancer, and mental health and suicide prevention. Their biggest fundraising challenge is ‘grow your mo’ when men grow out their moustache for the full 30 days of November, getting friends, family and colleagues to sponsor them for their hirsute efforts (hence the name, Movember).

But they also run the Move challenge, encouraging people to attempt a new activity, get fit and raise funds while they do it.

How did Movember start?

The Movember Foundation began in 2003 when two Australian friends, Travis Garone and Luke Slattery, decided to bring back the moustache in aid of charity. They enlisted 28 others, becoming the original 30 Mo Bros. In 2004 they expanded their horizons, started the Movember Foundation and by 2007 people around the world were getting involved in Movember, growing their own moustaches and talking about men’s health issues.

There are now roughly 5million ‘mo bros and mo sisters’ worldwide.

What is Movember achieving?

By 2030 The Movember Foundation are planning to reduce the number of men dying prematurely by 25%, and with 5 million participants, with more getting involved every autumn, that percentage is only set to grow.

Since they started out 13 years ago, the charity has funded more than 1,200 men’s health projects around the world. And their vision? They say it’s “to have an everlasting impact on the face of men's health”.
