In the comments that followed this Robert Stacy McCain piece on contemporary feminism, McCain and Roxeanne de Luca found themselves talking about the pole vault, an event that hasn’t been always open to women. “The powers that be,” said de Luca, “told us that it was bad for our uteruses.” McCain, not too surprisingly, called for an investigation into this claim once he gets an NIH grant, possibly to steal a march on noted amateur gynecologist Andrew Sullivan.
I, of course, have no idea as to whether this is true or not, but I am reasonably certain it’s not a factor as regards external appearance:
Mary Sauer is an American pole-vaulter; she appeared unclothed in the September Playboy  “Women of the Olympics” pictorial. I of course had checked out the fine print, and had found this little gem:
“I’m afraid of heights. But when I pole-vault I can’t tell how high in the air I am. I’ll go driving down the freeway and see an overpass sign that reads CLEARANCE 14 FEET, 10 INCHES, and I think, Wow, I’ve jumped over that.”
She continued to vault through 2007, at which time she was in her early thirties; I rather suspect that if something horrible had happened to her internal workings, we’d have heard about it.
