A close-up of a cervix is not what you'd expect to see on the telly on a Sunday night, but there it was in living, breathing colour.
It was a little disconcerting, so I went back to Late Night With Conan O'Brien on CNBC (Sundays, 9.45pm) who was interviewing Queen Latifah, via a few seconds with the Girls Of The Playboy Mansion (E! Entertainment, Sunday double bill from 9.30pm).
It was about all I could handle of Holly, Kendra and whoever the other one is, with their fake blonde hair and fake boobs.
But eventually, after Conan had finished with The Simpsons creator Matt Groening - who named Homer after his dad, and his son after Homer, poor kid - I ended up back on Discovery for the tail end of The Orgasmatron.
The programme was about a doctor who had invented a device that would help women to achieve orgasm.
Apparently a trip to Adult World is not the solution for everyone. There are millions of women who never feel the earth move for serious medical reasons, and not just because their boyfriends couldn't be bothered to stop to ask for directions.
Three of them took part in the experiment, which involved an electrode being placed in the spine.
The precise positioning followed by an electronic pulse would then produce the desired result, virtually on demand, via a handheld device.
That was the theory, anyway.
The first woman was found to have a blockage in that part of her spine, which prevented the correct placement of the electrode, and tragically, there was no hope for her.
Woman number two was the winner and went on to have a fabulous couple of days (or hours, it wasn't exactly clear) with her husband, emerging flushed and grinning from ear to ear.
It might be worth adding that these were all rather elderly people, and definitely not of the porn star variety. They fell into the same category of picturing your parents having sex. It's not an image you want to live with, but I was very happy for her nonetheless.
The third woman had moderate success, but what got me was that at the end of the experiment, they took the electrodes out of all of them - even the one on whom it had been a resounding success. I thought that was rather cruel.
She remained upbeat, saying that at least she had had the experience. All the husbands look dutiful and supportive, and slightly panicked. And so they should. At least one of them has a lot to live up to.
