In thisstudy, we systematically compared the effects of BPM and BPA on thereproductive neuroendocrine system of female mice during puberty.Five-week-old female ICR mice were exposed to BPM and BPA at dosesof 1 μg/kg bw/day, 50 μg/kg bw/day, and 1 mg/kg bw/dayfor 14 days. Both chemicals induced comparable adverse reproductiveoutcomes at 50 μg/kg bw/day and 1 mg/kg bw/day, including reduceduterine weight, disrupted estrous cyclicity, depletion of primordialfollicles, and increased follicle atresia. However, BPM and BPA haddivergent effects on molecular and hormonal end points. BPM exposuresignificantly elevated ovarian <em>Cyp19a1</em> expression,as well as serum estradiol (E2), follicle-stimulating hormone (FSH),and luteinizing hormone (LH) levels, whereas BPA did not significantlyalter any of these parameters. Mechanistically, BPM acts as an ERantagonist, reducing functional E2–ER complexes and creatinga perceived “E2 signaling deficiency”. This triggerscompensatory upregulation of ovarian ERs and steroidogenic genes (<em>Star</em>, <em>Cyp19a1</em>, and <em>Hsd17b1</em>), leading to enhanced E2 synthesis. The resulting hyperestrogenismexerts positive feedback on hypothalamic GnRH neurons, driving sustainedgonadotropin secretion and creating a self-sustaining high-E2 loopthat disrupts estrous cyclicity and follicle dynamics. In contrast,BPA, as a weak ER agonist, partially substitutes for endogenous E2at ERs, preventing the perception of E2 deficiency. Consequently,no compensatory steroidogenic activation occurs, and hormone levelsremain unchanged. Despite these distinct mechanisms, both compoundsimpair female reproductive function. Importantly, BPM exerted morepronounced endocrine disturbances than BPA, raising concerns regardingits use as a safer alternative.
