Ongoing pregnancy rates in in vitro fertilization are not dependent on the physician performing the embryo transfer.
OBJECTIVE
To analyze the influence of the factor of the physician performing the ET with a standardized procedure on the ongoing pregnancy rates in an IVF-ET program.


METHODS
Prospective observational study.


METHODS
Tertiary university hospital.


METHODS
Subfertile women with an IVF indication.


METHODS
None.


METHODS
Ongoing pregnancy.


RESULTS
Six physicians performed 977 ETs. Ongoing pregnancy rates ranged from 19.1% to 29.0%, with an average rate of 23.1%. Logistic regression analysis revealed that physician is not a statistically significant variable. Differences between the pregnancy rates achieved by the physicians are within the limits of random variation.


CONCLUSIONS
The probability of success in IVF is not dependent on the physician, provided the transfer procedure is standardized.
