Telomere Length in Human Polar Body and Telomere Length in Cumulus Cells: A Clinical Validation Study
NCT04577560 · Status: UNKNOWN · Phase: NA · Type: INTERVENTIONAL · Enrollment: 10
Last updated 2021-06-09
Summary
To investigate whether telomere length (TL) of the first Polar body (PB) correlates with TL in Cumulus cells (CC)
Conditions
- Telomere Length
Interventions
- GENETIC
-
First polar body biopsy in MII oocytes
Since PBs are by-products of the meiotic division of the oocyte and are not required for fertilization and subsequent embryo development, they can be removed to assess exclusively maternal chromosomal information without harming the embryo integrity. As previously described, PB biopsy does not impact the morphokinetic parameters of the embryo development and can be safely applied without the risk of impairing the reproductive potential of the embryo.
