Men in China participate in childbirth simulation

In honor of Mother's Day, some men in Nanchang City, China were voluntarily hooked up to machines that simulated labor pains ... and their reactions were priceless. Here's ABC:

"Doctors wired 20 men in China to a machine that simulated the pain of childbirth by sending electric shocks to the abdomen for 30 seconds... hello, average labor 12-14 hours, just saying."

Yep ... those men don't look too comfortable.

According to The Huffington Post, the machines replicated childbirth pain on a scale of 50 to 500. One of the men who participated said: "I couldn't stand much of it all. I understand now why my wife screamed for drugs when she was giving birth."

Most of the men didn't even make it through the full 30-second simulation, and as "Good Morning America" anchor Amy Robach pointed out, labor typically lasts quite a bit longer than 30 seconds. One man, however, did what he could to withstand the machine's highest pain level.

According to the Daily Mail, Zhou Nan managed to make it to the 500 mark on the agony scale. "I am the father of triplets and wanted to understand the great pain my wife experienced when she was giving birth. It was horrible. I have nothing but deep admiration for all mothers after this ordeal."

But this isn't the first time men have tried to understand what birthing pains feel like.

In 2012, two Dutch men simulated labor for their show "Guinea Pigs." That didn't go well, either.

Actually, pretty much any time these labor simulations have been done, they've ended with men in the fetal position. After participating in a similar experiment in 2009, Dr. Andrew Rochford said in Bust Magazine:

"Men of the world, you have no idea. Leave it to the women. Forget the whole pain threshold debate. We have nothing. Women win. Men don't. The end."

That was after experiencing so-called labor pains for 3 hours. The organizer of the event in China said: 'This can help people realize how great mothers are.'
