Fertility is one of the most important yield traits affecting economic gain in sheep breeding. Anti-Müllerian Hormone (AMH) is widely recognised as a dependable biomarker for assessing ovarian reserves and fertility potential. The aim of this study was to evaluate the dynamics of AMH during different phases of the sexual cycle in Norduz ewes the non-breeding season. Additionally, the study sought to assess the effects of age and body condition score (BCS) on AMH concentrations during these phases. A total of 32 Norduz ewes with a body condition score (BCS) of 3-4.5 and aged between 2 and 4 years were used as animal material in the study. All experimental procedures were carried out outside the breeding season and when the ewes were lactating. In all ewes in anestrus, intravaginal sponges (Esponjavet, 60 mg MAP, Hipra, Turkey) were kept in the vagina for 7 days for estrus synchronisation. Intramuscular injections of PMSG (Oviser, 500 IU, Hipra, Turkey) and PGF2α analog (Gestavet, 50 μg, Hipra, Turkey) were administered 48 h prior to sponge removal. Twenty-four hours after sponge removal, ewes were exposed to the ram for estrus detection. Since 5 ewes did not show estrus, blood samples were collected regularly from animals (n = 27) in which estrus was detected at three different stages: one just before the insertion of vaginal sponges (anestrus), another when heat was detected exposing to the ram (estrus), and the final one 10 days after estrus (diestrus). The serum samples were assessed for the levels of AMH and progesterone through the electrochemiluminessence immunoassay technique (ECLIA). The results of the analyses showed that serum AMH concentration did not vary between anestrus, estrus and diestrus phases of the sexual cycle of Norduz ewes outside the breeding season (p > 0.05). Furthermore, age and BCS had no effect on progesterone and AMH levels in different phases of the sexual cycle (p > 0.05). In conclusion, this study shows that serum AMH levels are constant at any stage of the estrus cycle. This suggests that phenotypic evaluation of ewes can be performed with a single measurement and that AMH is a reproducible and dependable biomarker that can be measured at any stage of the estrus cycle at an arbitrary time point.</p>","PeriodicalId":21035,"journal":{"name":"Reproduction in Domestic Animals","volume":"60 2","pages":"e70010"},"PeriodicalIF":1.6,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11843185/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143468951","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The objective of this study was to build an expertly annotated database of sperm images and to generate an illustrated guide with examples of the different sperm morphology presentations to promote standardisation in dog sperm morphology classification. Semen samples (n = 42) were obtained either from dogs presented for fertility evaluation or from semen doses used for artificial insemination. For image acquisition, wet preparations were prepared and evaluated using phase-contrast optics under 1000× magnification. Selected images were cropped so that only one sperm was included in each file, and a database of 8817 images was created. The images were classified by three veterinarians, specialists in animal reproduction (Diplomates American College of Theriogenologists) according to different criteria. Agreement among evaluators was the criterion used to create a database with reconciled classification. Complete agreement on defect category and morphological classification was observed on 70.2% of the images, and at least two veterinarians agreed on the classification of another 27.4% of the images; therefore, the reconciled database classification was based on the consensus of at least two veterinarians on 97.5% of the images. The percentage of morphologically normal sperm in the reconciled database was 57%, with the primary defect involving the sperm head, midpiece, or tail in 18%, 20%, and 5% of the cases, respectively.

When the total prevalence of specific defects was computed, the reconciled database contained 18% sperm head abnormalities, 22% midpiece abnormalities, and 7% tail abnormalities.

We further found that aging disrupted spindle assembly and chromosome arrangement, impaired actin polymerisation and reduced mitochondrial activity and function. Moreover, aging increased ROS levels; thereafter, DNA damage and apoptosis was induced in the porcine oocytes. Interestingly, treatment with 2.5 μM equol during the aging process significantly mitigated the above-mentioned defective parameters in porcine oocytes and finally improved embryo development rates.
