Outside, Abed paces back and forth, his arms crossed behind him, his head bowed.

It is the second time he has had to see his son in a hospital and he is clearly nervous.

He calls his wife back in Bangladesh.

"The surgery will go on all night," he tells her. "Get a megaphone and tell the whole neighborhood to pray for him. It is now in God's hands."

He checks his watch. It's only 9:05 a.m.

Beep, beep, beep.

Inside the OR, Gearhart readies to make the first incision.

What the doctors are hoping is that Okkhoy was left with enough of his own penile tissue, hidden inside his body, that they can pull out.

The tests they did earlier in the week suggest there isn't. But MRIs have been wrong before.

Everything now rests on what Gearhart finds.

"So, let's have a look," he says.

A few short minutes go by.

Gearhart: "I'll tell you, Rick, I'm getting a little more encouraged, you know? I really am."

Redett: "The good thing is, it's sensate too."

Gearhart: "It's sensate, absolutely! The good Lord made this one sensate.... Can we have a ruler? Yeah! Good for him. Good for him!"

Exactly 34 minutes after he walked into the operating room, Gearhart walks out -- and heads straight for the waiting room.

"So we have some wonderful news. Wonderful news," he begins.

In males, part of the penis is held inside the body, tucked up inside the pelvis and attached to the pubic bone. Think of a tree where we only see the part above ground; not the root hidden below.

"After we took all the scar tissue away and after we took all the skin away, we actually found that there is a reasonable amount of penis down, submerged under the skin, under the scar, that's usable," Gearhart says.

"So, therefore, we're not going to have to make him a new penis."

The doctors also found they would be able to move the urethra -- the tube used for urination -- to the tip of Okkhoy's penis. Translation: He will no longer have to relieve himself from the tiny hole the doctors in Bangladesh bore.

"Oh very good news! Very good news!" Abed exclaims.

Abed soon learns there are even more reasons to celebrate.

The penile tissue is "sensate," meaning Okkhoy will be able to have sensations and erections. And the tissue will cause his penis to grow as Okkhoy grows.

Abed can't hold back tears.

"Hey Allah," he sighs with relief, thanking God.

Khan too cries. She's been by the family's side for more than a year now, fighting for Okkhoy.

"All these months, all the worry. All this has borne fruit," she says.

Instead of 10 hours on the operating table, the surgery takes less than three.

Redett's team uses skin from Okkhoy's thigh for the shaft of the penis and tissue from his inner cheek lining to create the glans, or tip.
