Evaluation of a strategy for difficult embryo transfers from a prospective series of 2,046 transfers.

ABSTRACT:

Objective

To evaluate an embryo transfer strategy for difficult transfers (DiTs).

Design

Prospective, nonrandomized, observational, cohort study.

Setting

A hospital fertility center in France.

Patients

Data were collected on all embryo transfers conducted using the strategy between February 2014 and February 2020.

Interventions

Anatomical characteristics that could cause DiT were identified by transvaginal ultrasound and the catheter was adapted accordingly. Transfer was guided by transvaginal ultrasound. After passage through the cervix, a rest period was introduced to allow any contractions to stop before embryo deposition in the uterus.

Main outcome measures

The primary criterion was the percentage of pregnancies per transfer (P/T) after an eas
