Endometrial Stromal Cell Senescence: A Non‐Negligible Factor in Recurrent Pregnancy Loss

iMetaMed, EarlyView.
As populations age, links between female reproductive aging and infertility are increasingly evident. Cellular senescence, characterized by near‐irreversible cell‐cycle arrest and accumulation of damage, can impair tissue function. In the endometrium, aberrant senescence of endometrial stromal cells (EnSCs) may compromise receptivity, hinder embryo ...
