Working with a leading fertility clinic in Toronto can provide you with access to a wider range of treatment options in addition to standard reproductive medicine services like in-vitro fertilization, or IVF. One option that your physician may recommend is blastocyst transfer which requires the sophisticated laboratory setting of an advanced reproduction institute like ReproMed.
A day 3 embryo is one where it has been fertilized in the lab and grown for 3 days. A good quality day 3 embryo is far enough along the developmental stage to implant into the uterus. This is ideal as it allows the embryo to grow in the uterus, its natural environment. If a patient has a limited number of embryos to work with, a day 3 transfer will often be the best choice to proceed with a transfer. In some cases, it may be beneficial to culture the embryos further to day 5 (blastocyst) and then transfer.
Culturing to Day 5
If the patient has a large number of fertilized embryos to work with, the embryologist may allow for continued culturing of embryos in the lab to the blastocyst stage. The embryos that make it to day 5 are typically the best quality and become the ideal ones to use in a transfer. In this scenario, since the embryologist will now know the best quality embryo, a choice can be made to transfer a single embryo (the best quality) to avoid multiple pregnancies. Such a scenario is only considered when there are larger pool of embryos to work with. It would be very unfortunate to culture to day 5 with a limited number of embryos and have none develop to this stage. Such a scenario would leave no embryos to transfer.
Following Failed Implantation in a Previous IVF Cycle
If you have undergone unsuccessful IVF cycles, it is natural to feel frustrated and take on a negative attitude about your reproductive care. However, it is possible to learn from failed IVF cycles and make adjustments as your next cycle approaches. If you produced high-quality day 3 embryos in a previous cycle, but these failed to implant, a blastocyst transfer may boost the likelihood of successful implantation. The embryologist may culture existing frozen day 3 embryos to day 5 to ensure they have grown to their full potential before transferring.
