Cryopreservation

Cryopreserving or freezing embryos

Cryopreserving or freezing embryos

Although several embryos are generally obtained after classic ovarian stimulation following the retrieval of eggs, a single embryo at a time is transferred to the uterus in women under 37 years of age. However, it’s possible to freeze the extra embryos for use in the future. Transferring a frozen embryo is much simpler since it’s not necessary to extract eggs. This transfer is generally achieved in a menstrual cycle that is nearly natural or stimulated.
