Prolonged duration of transfer does not affect outcome in cycles with good embryo quality.

The objective of investigating the impact of the time that embryos remain in the catheter on the outcome of cycles was assessed by measuring the period between loading the catheter and discharging the embryos in 300 transfer cycles. The pregnancy and implantation rates were similar in cycles with good embryo quality regardless of transfer duration.
