The developmental capacity of bovine embryos produced in vitro (IVP) is often reduced due to suboptimal culture conditions, inducing oxidative and endoplastmatic reticulum (ER) stress. Tauroursodeoxycholic acid (TUDCA), a chemical chaperone, has shown potential to improve embryo developmental potential sustainably. However, its mechanistic effects remain unclear. This study investigated the impact of 200 μM TUDCA supplementation during in vitro culture on embryonic development, cryotolerance, gene expression, and mitochondrial bioenergetic activity. While cleavage and day 7 blastocyst rates were unaffected, TUDCA significantly increased blastocyst formation on days 8 and 9. Cryo-survival assessments revealed enhanced re-expansion and hatching rates in day 7 blastocysts post-thaw. Gene expression analysis demonstrated significantly reduced expression of oxidative stress (NFE2L2, SOD2, PRDX1) and an ER stress marker (ATF4), with no changes in BAX or HSPA5 expression. Extracellular flux analysis revealed significantly lower basal respiration, ATP-linked respiration, and maximum respiratory capacity in TUDCA-treated embryos, suggesting a metabolically quieter phenotype. These findings support the "quiet embryo" hypothesis and suggest that TUDCA promotes a more balanced mitochondrial bioenergetic profile, ultimately enhancing embryo quality and resilience under in vitro conditions.
