 | | The blastocyst culture conditions do not improve the health or viability of an individual embryo which is not otherwise able to develop for 5 days in vitro and then implant; rather it allows embryos capable of sustained growth to continue in culture and reach their maximum inherent capability. | | | The ability to grow embryos for five days to the blastocyst stage of development in the laboratory, rather than the traditional three days, allows clinicians to determine with greater certainty which embryos are really the "best" in terms of their potential for implantation. | | | The Infertility and IVF Center’s experience in Blastocyst Culture. |

| | Blastocyst Stage Embryo Transfer |
| | Blastocyst culture and embryo transfer is a new and emerging technology for human assisted reproductive medicine. | | | As a consequence of a single blastocyst transfer, the overall pregnancy rate may then be no greater than that which we already experience with the transfer of three to four embryos on day two or three after egg retrieval. | | | The primary risk of attempting blastocyst transfer is that some embryos will die in the laboratory. |

| | IN VITRO FERTILIZATION AND EMBRYO TRANSFER |
| | Blastocyst transfer is probably not advantageous for patients who develop few eggs or embryos. | | | However, with blastocyst transfer, only two or three embryos are transferred, practically eliminating the possibility of triplets or greater. | | | When that happens, single blastocyst transfers will be considered the norm, and IVF will likely be considered the first-line infertility treatment. |

| | Therefore, a blastocyst has a higher probability of developing into a baby after transfer to the patient. | | | Our experience with blastocyst transfer has changed the way that we counsel patients with strong concerns about multiple pregnancies. | | | As a result, enhanced or equally successful pregnancy with blastocyst transfer is achieved with fewer embryos and a reduced incidence of multiple births. |

| | Morhological Scoring of Human Embryos and It's Relevance to Blastocyst Transfer |
| | By determining how the quality of blastocysts formed on day-five/six during extended culture is related to their morphology as previously assessed on day-three, it is possible to use blastocyst formation as a measure of potential viability. | | | Earlier stage assessment of embryonic morphology at the cleavage stage or even the pronucleate (1-cell stage) have their place, but can never be superior to later stage assessment assuming culture conditions are optimal. | | | Regardless of the relative environmental merits of in vivo or vitro development, it is understood that approximately 120 hours (day-five) into development the healthy human embryo should be at the blastocyst stage. |

| | There is no law that prohibits fertility clinics from tossing the no-longer-needed blastocysts into the trash. | | | (I say why not—since there are so many blastocysts out there.) What if there are problems with the pregnancy and the birth does not occur? | | | But one does not have to push Bush and DeLay too far to the logical extreme to ask a rather practical though difficult question: Well, guys, what should be done with these blastocysts? |

| | • Blastocyst transfer however involves extending the period that the embryos are cultured in the laboratory to 5 or 6 days. | | | • Blastocyst culture has become a very valuable tool in our treatment armoury. | | | • It is possible that you may not have an embryo transfer at all – about 20% of the patients we have treated to date with blastocyst culture have not reached embryo transfer. |

| | By this reasoning, the blastocyst is morally just like a person, endowed with the same basic human rights. | | | Many believe that life begins the moment the egg and sperm fuse to form the first cell. | | | There are also stem cell researchers who believe ensoulment occurs quite early, but later than the blastocyst stage. |

| | There are several benefits to doing a blastocyst transfer over a traditional 2-3 day transfer. | | | Embryos were transferred on day 2 or 3 not because it was optimum, but because it was their only choice. | | | A five-day-old embryo is called a blastocyst, and there is something magically different about a blastocyst than from any other stage preceding it. |

| | By using these more developed embryos, we are able to identify those that are most likely to result in a successful pregnancy. | | | Initial studies published by Dr. David Gardner of the Colorado Center showed that a blastocyst transfer increased the implantation rate per embryo from 21% to 46%. | | | In blastocyst transfer, infertile women are implanted with embryos that have matured for five days (to the blastocyst stage). |

| | This stage in the developing embryo is the blastocyst, and lasts approximately until the implantation in the uterus. | | | The syncytiotrophoblast implants the blastocyst in the epithelium of the uterus by forming finger-like projections called villi that make their way into the uterus, and spaces called lacunae that fill up with the mother's blood. | | | In: trophoblast cells which eventually form the placenta, and inner cell mass (also called embryoblast) of undifferentiated cells which are a source of embryonic stem cells. |

| | Blastocyst Transfer |
| | Blastocyst transfers are not appropriate for all patients undergoing IVF. | | | Women who fall into these categories are encouraged to have their embryos transferred after the usual three days of development because blastocysts do not respond to embryo freezing as well as earlier stage embryos. | | | Similar to the concept of using HIP embryos, blastocysts are “healthier” and have more ability to continue to grow and divide. |

| | Blastocyst Transfer |
| | With further refinement, it may be possible to transfer only one or two blastocysts, which again avoids the complications imposed by multifetal pregnancy. | | | However, new information about the physiologic requirements of developing embryos has led to the production of nutrient media which allows embryonic development to progress to the blastocyst stage. | | | This advanced stage of development is associated with a high rate of implantation and subsequent pregnancy. |

| | In a cyclical process of hormonal stimulation, the ovary is induced to continue producing progesterone while human chorionic gonadotropin (hCG) is released by the trophoblast cells of the implanting blastocyst. | | | Endometrial glands in the uterus enlarge in response to the blastocyst and the implantation site becomes swollen with new capillaries. | | | The trophoblast cells secretes an enzyme which erodes the epithelial uterine lining and creates an implantation site for the blastocyst. |

| | What are embryonic stem cells? [Stem Cell Information] |
| | The blastocyst includes three structures: the trophoblast, which is the layer of cells that surrounds the blastocyst; the blastocoel, which is the hollow cavity inside the blastocyst; and the inner cell mass, which is a group of approximately 30 cells at one end of the blastocoel. | | | The embryos from which human embryonic stem cells are derived are typically four or five days old and are a hollow microscopic ball of cells called the blastocyst. | | | They are not derived from eggs fertilized in a woman's body. |

| | Once the cavity appears, the morula becomes a hollow ball of cells called a "blastocyst." Within the blastocyst, cells in one region group together to form an inner cell mass that eventually becomes the embryo. |

| | The presence of the blastocyst indicates that two cell types are forming: the embryoblast (inner cell mass on the inside of the blastocele), and the trophoblast (the cells on the outside of the blastocele). | | | With the appearance of the cavity in the center, the entire structure is now called a blastocyst. | | | Cells flatten and compact on the inside of the cavity while the zona pellucida remains the same size. |
