Clinical Trial Summary

Assessing whether Preimplantation Genetic Testing for Aneuploidy (PGT-A) can increase the ongoing pregnancy rate per transferred embryo and can decrease the time to pregnancy and miscarriage rate in patients with Recurrent Implantation Failure (RIF)

Recruitment information / eligibility

• Status: Recruiting
• Enrollment: 100
• Est. completion date: December 1, 2023
• Est. primary completion date: December 1, 2022
• Accepts healthy volunteers: No
• Gender: Female
• Age group: 18 Years to 40 Years

Eligibility

Inclusion Criteria:

• Women with recurrent implantation failure (previous transfer of least 4 good quality embryos in at least 3 fresh or frozen cycles)

• BMI < 35

• Normal hysteroscopy

Exclusion Criteria:

• thin endometrium in previous cycles (<6mm), endometriosis ASRM score III-IV, premature ovarian failure (POF, Bologna criteria), abnormal karyotype, donor oocytes or embryos, PGT-M

Related Conditions & MeSH terms

• Aneuploidy
• Recurrent Implantation Failure

Intervention

Procedure:
• PGT-A
ovarian stimulation, oocyte aspiration, embryo culture until the blastocyst stage (day 5/6), TE biopsy, vitrification of all embryos in the blastocyst stage, PGT-A by NGS and finally embryo transfer of genetically normal embryos in cumulative frozen-thawed embryo transfer cycles
• Control
ovarian stimulation, oocyte aspiration, embryo culture until the blastocyst stage, fresh embryo transfer of the morphologically best embryo on day 5/6, vitrification of supernumerary embryos and embryo transfer in cumulative frozen-thawed embryo transfer cycles if not pregnant from the fresh cycle.
