Egg Freezing Test Process Service

It is possible to cryopreserve sperm and embryo at -196º C in liquid N2 by computerized slow cooling method. Subsequent cryothaw cycles treatment becomes cost effective and patient does not require undergoing active cycle management. Embryos and sperms can be kept cryopreserved for years.Recently developed vitrification technique uses rapid cooling of embryo. A. Embryo B. Semen C. Oocyte A. Cryopreservation and Vitrification of Embryo Egg retrieval under ultrasound guidance and subsequent fertilization and embryo culture are carried out according to our current procedures. If there happens to be a surplus of embryos following selection for fresh transfer (usually between one to four embryos are transferred to the uterus), then embryos of sufficient quality may be considered for cryostorage. While embryos can be frozen at any preimplantation stage between one-cell (one day old) to the blastocyst stage (5-6 days old). In certain cases where all embryos need to be frozen without a fresh transfer (e.g., when a woman may be at risk from ovarian hyperstimulation that might be complicated by pregnancy), we generally freeze all embryos the day after egg collection at the one-cell stage.
