Frozen Embryo Transfer, FET Cycles After IVF

Not very sexy, but it works

Storage tank for frozen IVF embryos
After the embryos are frozen in the controlled-rate
freezer in special straws, they are immersed
and stored in liquid nitrogen in this tank.
Liquid nitrogen is -196ºC (or -320ºF). That's cold...

When the couple is ready to use their frozen embryos we thaw them and transfer them back to her uterus.
