Transfer Strategy in an Oocyte Donation Programme

June 28, 2021 updated by: Elisabet Clua Obrado, Institut Universitari Dexeus

Pilot Study of the Best Transfer Strategy in an Oocyte Donation Programme: an Intention to Treat Randomized Controlled Trial

It has been previously shown that although the activation of the embryonic genome can begin as early as two days of initiation of the embryonic development (D2), it is expressed on day 3 (D3). Without this activation, the embryo can not continue its development. Therefore, it has been suggested that extended culture to blastocyst stage could be an option to identify and better select embryos that have been able to carry out this activation. The purpose of this study is to compare cumulative pregnancy and live birth rates following transfer of cleavage embryos or blastocysts.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Blastocyst-stage embryo transfer strategy
Intra-uterine transfer of blastocist if in cleavage embryo stage the oocyte recipient has a mínimum of 3 availables embryos with at least one of good quality to transfer and also the inta-uterine transfer of cleavage embryo (day 3) when the recipient doesn't have the previous criteria.
Active Comparator: Cleavage-stage embryo transfer strategy
Inta-uterine transferring of cleavage embryo transfer (day 3 of develpment) in oocyte recipients

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description

Total number of births considering fresh and frozen thawed embryos transferred
at 12 months after a embryo transfer (time considered enough in order to do a minimum of one frozen-thawed cycle if pregnancy is not achieved with the fresh cycle

Secondary Outcome Measures

Outcome Measure
Measure Description

Cumulative pregnancy rate
Time Frame: at 12 months after a embryo transfer (time considered enough in order to do a minimum of one frozen-thawed cycle if pregnancy is not achieved with the fresh cycle
Total number of pregnancies confirmed by ultrasound 6 weeks after embryo transfer including fresh and thawed embryos.
at 12 months after a embryo transfer (time considered enough in order to do a minimum of one frozen-thawed cycle if pregnancy is not achieved with the fresh cycle
