Hugh Jackman is spearheading a new campaign to raise awareness for testicular cancer by grabbing his genitals in a new online video.

The X-Men star posed with pals at the gym for the #feelingnuts viral campaign to encourage men to get their privates checked for the disease.

Like the summer's (14) IceBucketChallenge, which was launched to raise awareness about Als, those taking part in the new initiative must nominate pals to grab their gonads too.

Jackman challenged Ricky Gervais and Neil Patrick Harris. William Shatner has also posted a photo of himself grabbing his junk.
