Abstract

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.

Design: Prospective observational study.

Setting: Tertiary university hospital.

Patient(s): Subfertile women with an IVF indication.

Intervention(s): None.

Main outcome measure(s): Ongoing pregnancy.

Result(s): 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.

Conclusion(s): The probability of success in IVF is not dependent on the physician, provided the transfer procedure is standardized.
