Allison Penn, 31, and her husband, Tom, 46, had tried to have a baby for four years before they decided on in-vitro fertilization. What happened next blew everyone away–Allison defied one-in-200 million odds to give birth to identical triplets!

Logan, Eli and Collin Penn were born Wednesday at North Shore University Hospital on Long Island (where Jennifer Lopez delivered her twins) in an event so rare that an obstetrician estimated it might happen just once in 200 million births. Allison was impregnated with just one embryo through IVF, said Dr. Victor Klein, who delivered the boys. He said that one embryo split in half, and then one half of that split again, he said.

"This is the first one we're aware of in the literature in the country in which they only put back one embryo" and a woman gave birth to triplets, said Klein. He added that identical triplets are born at a rate between one in 60,000 and one in 200 million, depending on the research.

Allison and Tom had tried to have children since they got married about four years ago. "When it took us so long to get pregnant, I just assumed we were going to have one, and that would probably be it," she said. "So I thought one would be good."

"Everything we had done was to have one baby," Tom points out. "Anybody who says God doesn't have a sense of humor - everything we did was just for having one baby, and now we have three."

Congratulations, you guys! You hit the trifecta! Best of luck to you and your record-breaking sons!
