Sperm Cryopreservation — Freeze-Thaw Survival (3D)

A real 3D freeze-thaw survival model: spermatozoa swim inside a cryostraw suspended in a genuine WebGL scene, and the same glycerol-concentration / cooling-rate survival formula as the 2D simulator decides which cells make it through liquid nitrogen and back.

Spermatozoa swim inside a real 3D cryostraw as it moves from collection dish to controlled-rate cooling, liquid-nitrogen vapor and plunge, long-term storage, and rapid thaw. The same survival-fraction math as the 2D simulator — driven by cryoprotectant concentration and cooling rate — decides which cells stay green and motile and which turn grey, now rendered as genuine WebGL geometry you can orbit and zoom.
