This highlights the subtle differences in mechanism that functional selectivity is capable of creating, and which may be missed in many widely used assays of receptor function

Epigenetic modifications, including hypomethylation of ER and aromatase promoters, further sustain this estrogen-driven phenotype, with endocrine-disrupting chemicals (EDCs) such as dioxins and phthalates potentially exacerbating these epigenetic alterations ( Progesterone resistance, characterized by impaired progesterone receptor (PR) signaling despite bioavailable progesterone, perpetuates ectopic lesion survival and contributes to infertility ( The interplay of estrogen dominance and progesterone resistance disrupts endometrial homeostasis, directly impacting fertility
OS and mitochondrial dysfunction are associated with aberrant nuclear and cytoplasmic maturation, and the increased incidence of aneuploidy in advanced maternal age results from ROS-induced DNA damage, loss of chromosome integrity, SAC dysfunction, and telomere shortening
