Separately, a woman at about the same time actually volunteered to undergo a surgery specifically to observe the phenomenon on video, also by laparoscopy.
First of all - very cool that they were able to image this and work out the mechanical mechanism in such detail.
Second - the rupture event looks so violent but iiuc it’s actually highly controlled:
- the rupture site is thinned early in the ovulation process
- the expansion step pulls in fluid to the ovary (builds internal pressure)
- the contraction phase restricts the cell volume (which also builds internal pressure)
- the oocyte is launched out of the cell at a relatively high speed
Human ovulation incidentally caught during laparoscopic hysterectomy procedure in 2008:

I wonder why the video is age-restricted.
There are plenty of videos on YouTube that are clearly sexual in nature and publicly available to people of all ages.
Searching for the video ID (2-VKgdhfNpY) on Google Images returns obvious images of a laparoscopy.

How amazing is life!
And once a mouse is conceived, it goes through 28 Theiler states.

Nature orchestrates things perfectly.
I don't think the article mentions what animals this is about, but I was curious - this is in mice.
Below the first video, it says:
> Images were captured using a combination of confocal and two-photon microscopy, live imaging isolated mouse ovarian follicles.
Dang, thanks. Sloppy on my part!
Inmiced above. Thnaks!
At this point in mice must be a HN in-joke?

This is amazing. Thanks for posting.
I wonder if the title should be amended to clarify this- I feel as though one would assume from the title that this is imagery from humans.
