Embryo freezing

Embryo freezing preserves embryos not transferred in the current cycle, or all embryos in a freeze-all plan, so that later transfers can be done without repeating stimulation and egg collection. Not every embryo is suitable for freezing; the laboratory freezes those meeting its quality criteria. Storage requires written consent and ongoing fees.
