A Chinese martial artist shared video of he and his students taking repeated blows to the groin as means of promoting his unusual form of kung fu.

Master Wei Yaobin, known as the "Iron Crotch Kung Fu Master," appeared in a video alongside some of his students taking strong kicks to the groin, as well as being hit in the privates with objects including bricks and a battering ram.

Wei claims his form of kung fu can help men overcome erectile dysfunction and premature ejaculation.

The master said he previously only taught his form of kung fu, which he has been practicing for 10 years in the city of Luoyang, to family members, but he is now seeking to make his "Iron Crotch" methods more widespread.

"We want it to be more popular and accepted by public," Wei told AsiaOne.

He should try getting shot in the groin a few times and see how he compares to any random philanderer from Arizona.
