The Claim
In women with recurrent implantation failure undergoing IVF, a lower percentage of p16-positive senescent cells in the endometrial luminal epithelium (≤12.5%) and glandular epithelium (≤3.2%) is significantly associated with an increased risk of miscarriage, with these thresholds demonstrating 71–74% sensitivity and 71–74% specificity for predicting pregnancy loss.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In women undergoing IVF who have experienced repeated implantation failures, a lower proportion of p16-positive senescent cells in specific endometrial tissues is linked to a higher likelihood of miscarriage, with these cell thresholds correctly identifying pregnancy loss in 71–74% of cases.

When too few aging cells are present in the womb lining during the time when an embryo should implant, the tissue does not produce the right signals to welcome the embryo or prepare for pregnancy. This causes the embryo to fail to attach or be lost early.
What the research says
1 studyStudy: Decreased number of p16-positive senescent cells in human endometrium as a marker of miscarriage
Women who had fewer of these specific aging cells in their womb lining were much more likely to miscarry, and the study found that if the cell count was below certain levels, it could reliably predict who might lose the pregnancy.
