'place embryos'

This was a breakthrough in infertility treatment. The eggs are retreived by vaginal route (Ultra sound guided ovum pickup) and invitro insemination is done with washed sperm in the laboratory. Fertilization is achieved within 24 hours, Day 3 embryo transfer is done and the 4 to 8 cell embryos are carefully placed back in to the uterus

A recent advance in infertility treatment involves growing human embryos in the laboratory to a later "blastocyst" stage before transferring them into the uterus following in vitro fertilization. Advantages of blastocyst transfer: Theoretically, an embryo that dies in the laboratory before it develops into a blastocyst would also not have continued to develop in the uterus. The pregnancy rate per transfer is higher when blastocyst embryos are transferred on day 5 to 7 than when earlier-stage embryos are transferred on day 2 or 3.

Embryo Adoption is a well-established and successful form of assisted conception treatment where both partners are sub fertile. Indication for embryo Adoption * Menopausal and premenopausal woman and sub fertile partner. * Recurrent IVF Failures. Carriers of genetic disease or chromosomal abnormalities. The advantages of embryo Adoption are good use of excess embryos. Also the recipient bears the child and hence the bonding with it is the advantage over adoption. This is relatively a simple procedure, cheaper treatment compared to oocyte donation or IVF and fewer medical complications.

Cryopreservation is a process where sperms and embryos are preserved by cooling to very low temperatures -196 °C for future use.
