Blastocyst Stage Transfer
Blastocyst Transfer is a new important technique developed for IVF that maximizes pregnancy rates while minimizing risks.
An 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. IHR offers blastocyst culture to infertile couples undergoing IVF or ICSI who wish to avail themselves of its potential benefits.
IHR's expertise in blastocyst stage transfer lies in our willingness and ability to individualize our approach to best suit each and every one of our patients.

In blastocyst stage transfer, developing embryos are allowed to grow undisturbed to blastocyst stage in the laboratory. Every embryo usually hatches after it has reached the blastocyst stage. Good quality embryos reach this point usually on day five after fertilization, though some may take until day six. IHR routinely performs embryo transfers on the third day. In select cases, we will culture embryos to blastocyst stage before transferring them into the uterus.
Blastocyst transfers can increase the chance of pregnancy per embryo, while decreasing the risk of multiple pregnancies. We may find that only one blastocyst need be transferred in order to achieve an acceptable pregnancy rate. However, we also anticipate that individual clinical circumstances may lead us to recommend transfer of more than two blastocysts. Therefore, the final decision regarding the number of embryos transferred will remain a joint decision between the patient and physician on the day of transfer.
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. Consequently, blastocyst culture makes it possible to select the best one or two blastocysts vs. three or four early embryos to transfer back to the mother. This reduces the occurrence of potentially risky multiple births. IHR constantly strive to improve IVF success rates through the steady refinements of clinical and laboratory techniques. Clinical blastocyst culture and transfer is the next important step in that evolution.
Embryos transferred at the blastocyst stage have made it through key growth processes and typically offer a greater chance of implanting. Without compromising pregnancy rates, we need only return 1 or 2 blastocysts to the mother instead of the typical 3 to 4 early embryos. In fact, pregnancy rates in the group using blastocyst transfer may even be higher because the uterine lining is more receptive to the advanced embryos. In addition, if there are more than two available at the time of transfer, the remaining blastocysts may be cryopreserved for future use.
A significant benefit of blastocyst culture and transfer is the reduction of high order multiple births that can result from in vitro fertilization. This means that various obstetrical complications that may arise from multiple pregnancies can be minimized. It is especially important in helping patients avoid having to make the difficult personal and ethical decisions regarding selective reduction.
Perhaps less known is our work with individuals and couples who are considering assisted reproduction, but who are uncertain of their next step. We encourage anyone, before they make a decision, to consult with us. Currently, we are offering a FREE Blastocyst Stage Transfer E-Mail Consultation.
