Many doctors are in a hurry to transfer embryos back into the uterus on day 2 or day 3 and they tell the patient that the uterus is the best incubator for an embryo and that rather than keep the embryos out in the IVF laboratory incubator it’s better to put them back in the uterus because the human body is the right place for the embryo to be and the chances of implanting will be better if they put the uterus back into the uterus rather than keep the embryo in the lab because they don’t want to take a chance and they tell the patient that this is the right way of increasing the chance of achieving a pregnancy but the truth is that they’re lying to the patient because the right place for a day 2 or a day 3 embryo is not the uterus.
The right place for a day 2 or 3 embryo is actually the fallopian tube, but we do not have the technology to transfer embryos back into the fallopian tube, which is why we’re forced to put them in the uterus. Now, when you put a day 2 or day 3 embryo in the uterus, that’s really not the optimal place for it to be, which is why the failure rates of day 2 and day 3 transfers are so high because, physiologically, a day 2 or day 3 embryo belongs in the fallopian tube and it only reaches the uterus on day 5, by which time it’s called a blastocyst.
This is why good laboratories all over the world will routinely grow embryos to a day 5 stage in the IVF laboratory before putting it back in the uterus so that they know that their IVF laboratory is good enough to provide the best possible environment for these embryos and this is why the success rate is so high because they create a large number of good quality blastocysts and they’re very open and transparent with their patients because they’re so proud of their IVF skills that they happily share photographs of the embryos which they’ve created with their patients and this increases the patient’s confidence and trust levels in the doctors because they know that they’ve received good quality treatment.
However, a lot of doctors are very unsure about the quality of their IVF lab, which is why they want to dump embryos back into the uterus as quickly as possible and will often routinely do this on days 2 or 3, but because they know that the success rate of embryo implantation is much lower when you put back day 2 or day 3 embryos, they will then routinely transfer 3 or even 4 embryos at one time to increase the chances of at least one embryo implanting.
This is a very hit or miss random shot method of doing IVF and it has a very high failure rate simply because so many of these embryos fail to implant because they didn’t belong to the uterus in the first place and what’s even worse is many of these patients end up with twins or triplets simply because the doctor puts so many embryos back so irresponsibly which means not only do they have a very high miscarriage rate they also have a very high prematurity rate and they end up with no live babies at all but IVF doctors really don’t care because once they put the embryo back and the patient is then left to her fate whether or not she gets pregnant and if she does get pregnant they take the credit irrespective whether that pregnancy ends up resulting in a live birth or not and this is why patients need to be assertive and speak up and not allow doctors to transfer embryos on day 2 or day 3 but to insist that they grow them to day 5 and provide them with photographs because you have to mimic normal human physiology to maximize success rates and the good news is that IVF laboratory conditions and culture media have become so good these days that good labs can routinely do this even if you just have a single egg and a single embryo and this is in your best interests.
Of course, for doctors who put them back on day 2 or day 3 and the cycle fails, instead of accepting responsibility for the fact that the embryo didn’t implant because they followed poor quality IVF practices, they blame the patient for the failure and then tell the patient that in the next cycle they will have to use donor eggs or donor sperm or some such rubbish, which is just adding insult to injury. The only way to protect yourself from these bad doctors who take you for a ride is by being well-informed and insisting that they provide documentation and share information with you proactively, and you should do this even before you pay your consultation fees!
You can learn a lot about the doctor by checking out their website and asking the receptionist a simple question: Do you do only Day 5 (blastocyst) transfers and provide embryo photos routinely to all your patients?
