Hypoxia-inducible factors, HIF-1α and HIF-2α, act as master regulators of these processes by sensing oxygen tension and orchestrating cellular responses in metabolism, angiogenesis, immune regulation, and tissue remodeling.

Embryonic HIF-1α is primarily involved in early embryonic development, whereas embryonic HIF-2α is required for later developmental stages.
Pathological hypoxia or aberrant HIF signaling drives pregnancy disorders including preeclampsia, fetal growth restriction, recurrent pregnancy loss, and heavy menstrual bleeding.
HIF-1α and HIF-2α have distinct spatial and temporal functions across reproductive stages.
Mouse genetics demonstrate that disruption of either HIF-1α or HIF-2α causes non-redundant defects in reproductive success, including failed implantation, placental insufficiency, and fetal lethality.
Maternal HIF-2α regulates epithelial breakdown, trophoblast invasion, implantation mechanics, and vesicle-mediated trafficking.
HIF-1α and HIF-2α act as master regulators of early pregnancy-associated processes by sensing oxygen tension and orchestrating metabolism, angiogenesis, immune regulation, and tissue remodeling.
Defining distinct HIF-1α and HIF-2α roles supports development of therapies targeting hypoxia-responsive pathways in infertility and obstetric disease.
