Hello Dr. Doyle,
I am a 25 year old healthy soon to be GS with one previous healthy pregnancy. The ED is a 22 year old healthy woman with no previous pregnancies. This is her first time donating. I have agreed with my IPs to do a SET the first time and if the first time fails a DET/2BT. My IPs prefer to have a singleton and if a multiple pregnancy occurs it may be possible that they will choose to reduce.
I have read that transferring two or more embryos does not increase the change of pregnancy. That it only increases the chance of a multiple pregnancy.
Can you confirm this?
This varies from clinic to clinic. In my center (CT Fertility) the likelihood of success with single embryo transfer is 55% with almost no chance of twins ( except for when identical twins happen, which is very rare) while the likelihood of pregnancy following a 2-embryo transfer is 78% with a 40% chance of twins.
