I'm no expert on women's sexuality and biology, but this strikes me as highly implausible:

Amber Hartnell did not intend to have an orgasmic birth – it just happened. "Trying to have an orgasmic birth defeats the object," she says, "I just got into this ecstatic state where I had these peaks of orgasm. There were these rolling waves coming through me where I was laughing and crying. I didn't feel like I was having contractions. They were more like rushes. I did not actually experience pain, I experienced intense sensations."

My favorite quote:

Whether you believe in orgasmic birth or not, labour is not so unlike sex, says Christine Grabowska, senior lecturer in midwifery at Thames Valley University.

And eating is not so unlike vomiting, I suppose.  But the experience of them could not be more divergent.

I guess you could put me in the "skeptic" camp on the issue of orgasmic birth.  More to the point, I think there are probably better and less combersome ways to achieve climax.

OTHER BIRTH-RELATED NEWS: 

NASHVILLE – Legislation that would require death certificates be issued for abortions performed in Tennessee has likely failed this session.

The measure sponsored by Rep. Stacey Campfield, a Knoxville Republican, was withdrawn from consideration in the House Health Care Facilities Subcommittee on Wednesday. The companion bill has stalled in the Senate Judiciary Committee since last month.

Currently, each induced termination of pregnancy in Tennessee must be reported to the office of vital records.

Also withdrawn from consideration in the subcommittee was a bill requiring stillborn deaths to be placed in vital records and legislation that would define "inception of human life" to mean "the moment of conception."

AND THIS:  More babies were born in the United States in 2007 than in any other year in American history [NYT].

40% of the births were to unwed mothers, with the greatest rise among white women.  And don't think we're talking about unwed teens.  That number, while not as low as 2005 (the record low), is still near its lowest point.
