Cervical cerclage before blastocyst transfer in patients having cryopreserved embryo transfer

Cervical cerclage can be performed before blastocyst transfer in patients with cervical insufficiency who undergo cryopreserved ET. The procedure is especially relevant to patients in whom the cervical os is dilated and the distal cervical segment is short. Transfer of a single, high-quality blastocyst can result in pregnancy and birth.
