Question by Mother of twin boys: What is the difference in success rates of 3 day transfer vs 5 day transfer of IVF embryos?
We did 3 day transfer and I’m reading everywhere that day 5 is better. I am 27 year old female with PCOS in my first IVF cycle. We have been having trouble getting pregnant because my husband works out of town and timing was off.

You will get some here who say a 3 day transfer is best and some who say a 5 day transfer is best. My clinic finds that your odds increase 10% when doing a 5dt. Every RE will tell you different when it comes to transfer days. Some clinics argue there is no difference if all things are they same between the groups who do 3 and 5dt (Age, embryo quality, number fertilized). This article explains “Under natural conditions, the embryo remains in the Fallopian tube until the fifth day of development (blastocyst stage). The uterine environment on day 3 is not the same as the fallopian tubes. When sequential culture systems are employed to grow the embryos to the blastocyst stage, the conditions in the laboratory more closely resemble the Fallopian tubes. Therefore, the embryos are better off in the lab for day 4-5 of development.”

On another forum I belong to I know some who would never consider doing a 5dt and say they believe that the sooner you get the embryos back to you, the better. Those who do a 3dt get pregnant all the time!

You are young! You’ve got some great quality embryos transferred back to you! Things are looking good!!!
