       | 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
