Patients will undergo IVF/ICSI procedure, and experience oocyte aspiration, fertilization,blastocyst formation,conventional embryo morphology evaluation and trophectoderm biopsy before blastocyst cryopreservation. Preimplantation genetic screening (PGS) will be performed to select euploid embryo. The patients will go through up to three times of frozen-thawed transfers of euploid blastocysts until ongoing pregnancy or live birth is acquired. Only one euploid blastocyst will be transferred at a time.
Patients will undergo IVF/ICSI procedure, and experience oocyte aspiration, fertilization,blastocyst formation,and conventional embryo morphology evaluation before blastocyst cryopreservation. The patients will go through up to three times of frozen-thawed transfers of good quality blastocysts until ongoing pregnancy or live birth is acquired. Only one good quality blastocyst will be transferred at a time.
