"I know a couple of us did fertility treatments", nurse Paige Packard said at a news conference Friday.
A baby boom is brewing at a suburban Arizona hospital where 16 intensive care nurses recently discovered they are all pregnant.
"That's how I ended up finding out that everyone was pregnant".
"It's like we had some kind of pact going on". The baby fever is just a happy coincidence.
Rochelle Sherman, who is just over a month away from giving birth, said: "I don't think we realised just how many of us were pregnant until we started a Facebook group".
Some of the patients are noticing that so numerous nurses providing their care are carrying children.

One of the women said she and another nurse discovered they were pregnant, and were surprised to find that many of their colleagues are also expecting.
"I know a couple of us did fertility treatments", Paige Packard, one of the nurses, said at an August 17 news conference, according to CNN.
Another expectant mother, Jolene Garrow, jokingly stated: "We all formulated this plan to have the holidays off!" One patient insisted on touching her belly the night before, she said.
Administrators say they've been planning for months to ensure fill-in staff is available when the time comes.
The hospital has reassured patients there won't be a shortage of staff because the Banner medical centre has a pool of floating nurses to call upon.
"The 16 nurses are from three different critical care units", said Heather Francis, nursing director for various ICU units at Banner.
