In this study, we provided new evidence identifying multinucleated cysts as precursors for oocyte differentiation. Within these cysts, organelles migrate and aggregate to form Balbiani body (B‐body) and establish early cellular polarity. Concurrently, excess nuclei are expelled, enabling cyst‐to‐oocyte differentiation. The microfilament‐myosin II plays

Psychological stress activates the sympathetic–adrenal axis, elevating norepinephrine (NE) and suppressing reproductive hormones, thereby impairing male reproduction. Excess NE overactivates and desensitizes β‐adrenergic receptors (β‐ARs), triggering Sertoli cell ferroptosis and disrupting spermatogenesis.

This study demonstrates that patients with PCOS exhibit altered gut microbial profiles, and FMT from PCOS patients induces PCOS‐like symptoms in mice. Specifically, gut dysbiosis reduces 3‐HAA levels in the context of PCOS. Administration of 3‐HAA to mice alleviates PCOS by promoting de novo NAD+ synthesis.

ABSTRACT Climate change significantly impacts aquaculture by altering key water‐quality parameters such as temperature, dissolved oxygen, pH, ammonia, and turbidity—factors essential for effective brood fish management and seed production. This review critically examines how these environmental changes affect broodstock physiology, spawning performance,
