Firm versus soft embryo transfer catheters under ultrasound guidance: does catheter choice really influence the pregnancy rates?
In contrast to the previously published evidence, under ultrasound guidance, individual catheter choice does not statistically significantly affect the clinical pregnancy rate in a modern clinical IVF practice. This may be as a result of decreasing the incidence of difficult transfers and endometrial injury with ET under ultrasound guidance.
