Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Cleavage stage-thin endometrial
Patients transferred with cleavage stage embryo, with endometrial thickness ≤7mm on the day of HCG (human chorionic gonadotropin) administration for fresh cycles, or on the day starting to use progesterone for frozen thawed cycles.
Embryo transfer
For fresh cycles, embryos were transferred 3-5 days after oocyte retrieval; For frozen thawed cycles, embryos were transferred 3-5 days after starting to use progesterone based on the stage of cryopreservation.
Cleavage stage-medium endometrial
Patients transferred with cleavage stage embryo, with endometrial thickness 8-13mm on the day of HCG (human chorionic gonadotropin) administration for fresh cycles, or on the day starting to use progesterone for frozen thawed cycles.
Embryo transfer
For fresh cycles, embryos were transferred 3-5 days after oocyte retrieval; For frozen thawed cycles, embryos were transferred 3-5 days after starting to use progesterone based on the stage of cryopreservation.
Cleavage stage-thick endometrial
Patients transferred with cleavage stage embryo, with endometrial thickness ≥14mm on the day of HCG (human chorionic gonadotropin) administration for fresh cycles, or on the day starting to use progesterone for frozen thawed cycles.
Embryo transfer
For fresh cycles, embryos were transferred 3-5 days after oocyte retrieval; For frozen thawed cycles, embryos were transferred 3-5 days after starting to use progesterone based on the stage of cryopreservation.
Blastocyst stage-thin endometrial
Patients transferred with blastocyst stage embryo, with endometrial thickness ≤7mm on the day of HCG (human chorionic gonadotropin) administration for fresh cycles, or on the day starting to use progesterone for frozen thawed cycles.
