“In some IVF procedures, doctors may wait three days before transferring embryos to the uterus, while a five day transfer is used by others. The advantages and disadvantages may be debated by the scientific community, but understanding the pros and cons of such a procedure is important for infertile couples interested in the in vitro fertilization procedure.
Of course, a fertility specialist should be alongside when making such a decision, as their knowledge and experience is certainly something that couples should take advantage of when making such a decision.
Waiting five days before transferring embryos to the uterus allows the doctor to select the highest quality embryos for transfer. Choosing the best quality embryos for transfer is important for infertile couples, as it gives them a better chance of becoming pregnant.
An embryo that has been allowed to develop for five days is called a blastocyst. These embryos have developed two cell types and a center cavity filled with fluid. For more information about blastocyst embryos, patients should speak to a doctor in the field. In many cases, more educated patients turn out to be more successful patient, so consulting with a physician regarding this procedure may be beneficial to the couple.
One of the advantages of a five day transfer for IVF procedures is that five days is a more natural time for the embryo to make its way into the uterus. Many IVF procedures perform a transfer after two or three days, but embryos of this age are usually found in the fallopian tubes. Transferring after five days instead of two or three may reduce the risk of multiple births as well.
After two or three days, it may be more difficult to determine which embryos will be healthy enough to develop, while culturing embryos for five days will often give doctors a better idea of which embryos will be more likely to develop long-term. Therefore, fewer embryos may be transferred, which decreases the risk of multiple births.
The disadvantages associated with this method are minimal if the clinic performing the procedure is well-equipped and has quality control measures in place. Clinics with less than optimal culture environments may not have the same success rate as proficient clinics, making clinic selection an important task in this procedure.
Less than optimal clinics may have greater success with two or three day transfer methods. Speaking to a medical professional at a proficient clinic is important for couples interested in this procedure.”
