There are so many things that can influence whether a perfectly looking embryo actually “sticks”. But have you thought about whether the person doing the actual TRANSFER may have something to do with success rates?
10-year study comparing doctors
A study published in Human Reproduction in February 2020 looked at the success rates after transfer, comparing doctors. They studied the ongoing pregnancy rates (defined as a pregnancy lasting >12 weeks) and checked who performed the transfer. In total, they analyzed 19,824 cycles over a 10-year period. There were 32 doctors who carried out the transfers.
The researchers found that it did indeed matter who performed the transfer. The pregnancy rates ranged from only 8% (the worst performing doctor) to 29% (the best performing doctor). Quite a difference!
In their study, experience (defined as how many times the doctor performed an embryo transfer) didn’t matter much, and they concluded “experience does not assure proficiency for everyone“.
Food for thought?
