A tissue-clearing technique, CUBIC (Clear, Unobstructed Body Imaging Cocktails), was a suitable method for ovaries clearing, and a 3D method for oocyte counting was validated with accuracy of 105.22% ± 3.48%. By this method, GnRHa was also found to protect the loss of oocyte number (597 ± 28 vs. 222 ± 15, &lt;i&gt;p&lt;/i&gt; &lt; 0.0001), which may be mediated by upregulated anti-Müllerian hormone (AMH) levels inhibiting primordial follicle development approved by in vitro culture of ovaries. GnRHa also increased the number of retrieved oocytes in CTX mice (19.4 ± 2.1 vs. 15.0 ± 1.6, &lt;i&gt;p&lt;/i&gt; &lt; 0.0001) and developmental ability of oocytes (65.0 ± 4.6 vs. 48.1 ± 4.2 for blastocyst, &lt;i&gt;p&lt;/i&gt; &lt; 0.0001). RNA sequencing revealed GnRHa pretreatment downregulated pathways of exogenous drug metabolism, oxidative stress and cytochrome P450, validated by detection of adenosine triphosphate (ATP), MDA and ROS levels. The up-expression of &lt;i&gt;Cox17&lt;/i&gt; (cytochrome c oxidase copper chaperone 17) after GnRHa pretreatment was confirmed by PCR and microinjection of si&lt;i&gt;Co","PeriodicalId":50729,"journal":{"name":"Bjog-An International Journal of Obstetrics and Gynaecology","volume":"132 S2","pages":"107-119"},"PeriodicalIF":4.7,"publicationDate":"2025-02-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143460334","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
