Egg? and embryo? freezing
Cryopreservation allows medical professionals to store eggs, sperm? and embryos. This is commonly performed as part of the IVF cycle, since often many embryos are produced, and they need to be stored. The freezing of the eggs, sperm or embryos is now quite successful, in particular for sperm and embryos.
Scientists at the COGI conference discussed how this technique could also have positive effects on the IVF cycles for patients with PCOS. It would allow the stimulation cycle and the re-implantation? cycle to be separated. On one cycle the woman would have the ovarian stimulation, but the embryos are immediately frozen and re-introduced the following cycle when her hormones are more in control.
