Cryopreservation was once the domain of sci-fi novels and B-rate movies. (Think Encino Man.) Frozen embryos are something of a new ethical frontier in IVF. Because of improved fertility drugs and lab techniques, the average IVF cycle now yields more embryos than it once did. Many of those end up in the freezer, where they keep remarkably well.
It’s increasingly real, as the recent birth of a healthy boy from a frozen embryo created 20 years earlier shows. The birth, which is reported in a study in the online edition of the journal Fertility and Sterility, sets a record. Until now, no embryo frozen for this long has resulted in a live birth. Go science! [popularscience]
