Human ovulation caught on tape

Surgeons who were performing a partial hysterectomy witnessed a spontaneous ovulation and were lucky enough to have a camera to record the event. The pictures (I wish there was a video), will be published in the journal "Fertility and Sterility". Surprisingly, the ovulation was not an "explosive" event as it is assumed to be, but rather a 15 minute long and smooth release of the egg...

Wow that's cool. I had no idea eggs were that damn huge.

Is it really surprising that eggs don't explode out of the ovary?

So, is this the first time its been witnessed and recorded in humans?

Kevin Z: Apparantly it's the first time it's been captured with such clarity (according to the article, previous pictures were fuzzy)

Well it's been observed by ultrasound, but to take pictures is quite invasive and to time it right is hard, so to my knowledge it had never been photographed before.

As for the "non-explosive" nature of ovulation, it is surprising when you consider that the follicle is under tremendous pressure from the antral fluid. You would expect once the ovarian wall breaches (from the proteases digesting it) that the fluid and the egg would be expelled quickly.

Also Bayman, the egg appears big in part because it is surrounded by multiple layers of cumulus cells and extra cellular matrix. That stuff will come apart during the fertilization process. That being said it is the largest cell in the body (some might dispute that it is the neuron), and visible to the naked eye.

As for the "non-explosive" characteristics regarding ovulation, it can be unexpected the fact that the hair follicle is create-store-cards usually underneath remarkable strain through the antral fluid. You should count on if the ovarian wall breaches (from the particular proteases digesting it) the fluid and the ovum could be expelled speedily.
