Some patients, especially those on long-term or high-dose B12 treatment, may develop complications like: 1

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
