Live imaging of ovulation in action reveals three distinct phases in mice

Human ovulation incidentally caught during laparoscopic hysterectomy procedure in 2008:

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

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.
