Lipopolysaccharide (LPS)-induced inflammation is a well-established model of autoimmune POF in rodents. Immunomodulatory treatments involving corticosteroids, frankincense, and targeted secondary antibodies have been hypothesised to mitigate the autoimmune response, reduce anti-ovarian antibody (AOA) levels, and restore ovarian function in an LPS-induced POF rat model. A POF model was established in female albino rats via the intraperitoneal injection of LPS. The rats were then divided into groups that received no treatment (LPS control), dexamethasone (DEX-treated LPS-treated rats), methylprednisolone (MP-treated LPS-treated rats), frankincense (Frankincense-treated LPS-treated rats), or secondary anti-ovarian antibodies (secondary Ab-treated LPS-treated rats) for 3 to 4 weeks. The serum levels of AOA, 17β-oestradiol, follicle-stimulating hormone (FSH), and luteinising hormone (LH) were assayed via commercial enzyme-linked immunosorbent assay (ELISA) kits. Ovarian tissues were examined histopathologically to assess structural damage and recovery. LPS induction successfully created a POF phenotype, as evidenced by significantly elevated AOA levels (<i>P</i> <b> < </b>0.001), reduced 17β-oestradiol (<i>P</i> <b> < </b>0.001), elevated FSH/LH (<i>P</i> <b> < </b>0.001 and <i>P</i> <b> < </b>0.05, respectively), and severe histopathological damage, including follicular atresia. All the treatments restored 17β-oestradiol levels.

MP potently suppressed AOA but paradoxically elevated FSH, without improving ovarian histology. DEX and frankincense showed intermediate efficacy, improving some hormonal and serological markers but failing to achieve full histological restoration. These findings demonstrate that targeted immunotherapy using secondary antibodies is superior to broad immunosuppression or anti-inflammatory treatment for restoring ovarian function in patients with autoimmune POF.

This study evaluated the kinematic structure of the spermatozoan subpopulation in frozen-thawed Holstein and Jersey bull semen doses under different thawing protocols. We used frozen semen doses taken from four bulls of each breed. Nine semen doses were collected from each animal, for a total of 72 cryopreserved doses. Straw thawing was performed at three temperatures (35 °C, 37 °C, and 40 °C) and three times (30 s, 40 s, and 45 s). Sperm kinematic patterns were evaluated using a CASA-mot system (ISAS<sup>®</sup>v1). Sperm kinematic variables for each breed, temperature, and thawing time identified four subpopulations. The analysis revealed an effect of breed and semen thawing protocols (<i>P < </i>0.05) on sperm subpopulation distribution, sperm movement, and swimming patterns. Subpopulation analyses based on semen assessment are needed to further interpret the relevance and effect on fertility.</p>","PeriodicalId":23532,"journal":{"name":"Veterinarni Medicina","volume":"71 1","pages":"1-9"},"PeriodicalIF":0.8,"publicationDate":"2026-01-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12896123/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146202929","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
