May celebrated the birth of Kalea with the Fisk family at Saddleback Memorial Medical Center in Laguna Hills. She was the 10,000th baby delivered by the 68-year-old OB-GYN.
"It's unbelievable. It's hard to believe that it is actually possible," May said.
Over the past 43 years, May has delivered on average one baby every 38 hours. He admits he doesn't remember every single delivery, but he remembers the first.
"The first one I remember literally like it was yesterday. I was a medical student. It was Nov. 16, 1968 and a little baby boy," May said.
Over the past 40 years, May has seen many changes in his field. Two of the biggest include fathers being allowed into the delivery room and epidurals.
"Epidural anesthesia is a life saver for a significant number of people. That doesn't mean people don't' do it naturally, but there are always options, and the epidural anesthesia has made labor much more of a joy," May said.
As for how long May plans to keep delivering babies, he says he'll be here through 2015.
"It is a good job," May said. "It's a happy job."
