This reduction is exacerbated after surgery. Nevertheless, oocyte quality does not seem to be compromised in these patients. When embryos of good quality are obtained, in vitro fertilization outcomes are generally satisfactory. Oocyte cryopreservation may represent a fertility preservation option for women with planned and/or prior surgery, as it enables the collection of oocytes in advance. Given the diverse manifestations of endometriosis, which vary by type, age, and ovarian reserve, the decision to pursue oocyte cryopreservation should be weighed individually. Moreover, the potential benefits of this approach on future fertility must be carefully considered. Considering current guidelines, the most appropriate candidates for oocyte cryopreservation among women with endometriosis are: patients with bilateral endometriomas, typically larger than 3 cm; those with prior surgery for unilateral endometrioma who exhibit ipsilateral or contralateral recurrence; and those with unilateral endometrioma on a single ovary. However, the size criteria for endometrioma warrant further discussion. Conversely, oocyte cryopreservation is inadvisable for patients: with unilateral endometrioma smaller than 3 cm and good ovarian reserve; who have undergone surgery for bilateral endometriomas, regardless of recurrence; and who have diminished ovarian reserve. While consensus indicates that decisions regarding diminished ovarian reserve should be individualized, fertility preservation should often be considered for patients with serum anti-Müllerian hormone levels below 0.5 ng/mL.

Therefore, several recent studies have concentrated on the preservation and restoration of fertility to enhance the quality of life for affected individuals. It is currently recommended to biobank the tissue extracted from testicular biopsies to provide a later source of spermatogonial stem cells (SSCs). Another successful approach has been the in vitro production of haploid male germ cells. The capacity of SSCs to transform into sperm, as in testicular tissue transplantation, SSC therapy, and in vitro or ex vivo spermatogenesis, makes them ideal candidates for in vivo fertility restoration. The transplantation of SSCs or testicular tissue to regenerate spermatogenesis and create embryos has been achieved in nonhuman mammal species. Although the outcomes of human trials have yet to be released, this method may soon be approved for clinical use in humans. Furthermore, regenerative medicine techniques that develop tissue or cells on organic or synthetic scaffolds enriched with bioactive molecules have also gained traction.

These benefits were also evident after sperm freezing (p<0.05). Although chromatin abnormalities increased following vitrification, the treatment groups showed better outcomes (p<0.05). The tubular diameter, epithelium height, and luminal diameters remained unchanged with age. The tissue antioxidant capacity was greater in the groups receiving the high doses of vitamin E. Additionally, significant increases in inhibitor of DNA binding protein-4 (Id4) and GDNF family receptor alpha-1 (Gfra1) expression were observed in the higher vitamin E dosage groups, and promyelocytic leukemia zinc finger protein (Plzf) expression was notably present in the 400 mg/kg treatment group compared to the control group (p<0.05).</p><p><strong>Conclusion: </strong>Antioxidant supplementation might enhance reproductive outcomes in aging males. The observed effects included improved sperm cryo-resistance, which is advantageous for future applications such as sperm freezing or fertility preservation.</p>","PeriodicalId":46409,"journal":{"name":"Clinical and Experimental Reproductive Medicine-CERM","volume":" ","pages":"213-224"},"PeriodicalIF":1.8,"publicationDate":"2024-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11372309/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141296912","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
