If cervical stenosis is discovered at ET, and facilities or expertise were not available for immediate remedial action (such as TMET), then it is far better to postpone the transfer than persist with a difficult procedure. If the attempted transfer was performed on day 2 or 3 post–oocyte retrieval, then it could be postponed till day 5 or 6 [22]. This gives time to implement suitable steps to facilitate ET. Alternatively, the embryos could be cryopreserved for later transfer, allowing plenty of time to prepare. The aim should be an easy transfer, now or later.
