Trial Details


What is the research question being addressed?

Does autologous transfer of mitochondria derived from adipose stem cells into oocytes enhance oocyte quality and subsequent embryo development compared to standard intracytoplasmic sperm injection in patients with repeated IVF failure?

Intervention(s) planned

Study setting: The trial is conducted at Embryology laboratory at Wish Fertility Hospital under standard QA/QC protocols.

Method of randomization: In this pilot trial, randomization is performed at the oocyte level within each stimulation cycle. Sibling MII oocytes from the same patient are allocated as evenly as possible (approximately 1:1 ratio) between the intervention (Mito-ICSI) and control (standard ICSI) groups. Allocation is performed manually according to a pre-defined randomization schedule.

Intervention: Sibling MII oocytes will be randomly allocated to experimental (Mito-ICSI) or intracytoplasmic sperm injection (ICSI). Autologous mitochondria are isolated from patient’s adipose-derived stem cells under standard operating procedure (SOP) conditions. Co-injection is performed during ICSI with ~2-5 pL (according to diameter and length of injecting pipet) suspension per oocyte; control arm receives identical ICSI without mitochondria. Viable blastocysts from both groups will be biopsied for preimplantation genetic testing for aneuploidy.

Embryos from both arms may be generated. Transfer will follow standard morphology/kinetics and/or Preimplantation Genetic Testing for Aneuploidies (PGT-A) criteria, blinded to allocation. PGT-A allows retrospective tracking of embryo origin (Mito-ICSI vs control) for analysis.


Inclusion criteria

o Agree to participate to the study o 27-39 years old o Having at least three previous failed IVF trial o Agree to collect biopsies for Preimplantation Genetic Testing for Aneuploidy (PGTA) analysis o Agree to have single blastocyst transfer (recommended) o No major uterine or ovarian abnormalities o Agree to have all embryos frozen o Agree to collect adipose tissues from subcutaneous liposuction o BMI level level <26kg/m2


Exclusion criteria

o Ovarian endometriosis with Chocolate cysts (American Fertility Society-AFS type 3 and 4 ) o Any medical contraindication oocyte retrieval or subsequent procedures o Severe sperm abnormalities o <5 million/mL motile sperm o Uterine structural anomalies o Polycystic ovaries o Premature ovarian failure



Primary outcome(s)

1.

Transferable embryo rate per zygote on day 3 Rate of blastocyst development on day 5 and 6. Day 3 embryos are evaluated using Veeck’s morphological criteria to determine quality and transferability. Day 5-6 blastocysts are assessed using the Gardner grading system for expansion, inner cell mass, and trophectoderm quality. Furthermore, all embryos are cultured in a time-lapse incubator, which provides morphokinetic data and an additional objective scoring system. These combined assessments are standard practice in ART laboratories and provide validated outcome measures for embryo quality.
