Methods: This retrospective case-control study evaluated the effects of breast cancer on the ovarian response and on the oocyte quality. Oncological patients with breast cancer undergoing controlled ovarian stimulation cycles for fertility preservation, and age- and date-matched controls undergoing COH for in vitro fertilization (IVF) for male or tubal factor infertility were included in the study. Two hundred and ninety-four women were enrolled: 105 affected by breast cancer and 189 healthy women in the control group. Both groups were comparable in terms of age, BMI, and AMH value. Maximal estradiol levels on the triggering day, duration of stimulation, total amount of gonadotropins administered, number of oocytes retrieved, rate of metaphase 2 oocyte production, and numbers of immature and dysmorphic oocytes were analyzed. Results: Considering factors influencing the oocyte quality, such as age, BMI, AMH, duration of stimulation, E2 level on the triggering day, total FSH cumulative dose, stage, histotype, BRCA status, and hormone receptors, the univariate and multivariate analyses identified breast cancer as a risk factor for the presence of dysmorphic oocytes. Conclusions: The diagnosis of breast cancer does not seem to be associated with the impairment of the ovarian reserve, but is linked to a worsening oocyte quality.<\/jats:p>","DOI":"10.3390\/cancers14225718","type":"journal-article","created":{"date-parts":[[2022,11,22]],"date-time":"2022-11-22T03:13:41Z","timestamp":1669086821000},"page":"5718","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":12,"title":["Oocyte Quality Assessment in Breast Cancer: Implications for Fertility Preservation"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7525-2550","authenticated-orcid":false,"given":"Cristina","family":"Fabiani","sequence":"first","affiliation":[{"name":"Physiopathology of Reproduction and Andrology Unit, Sandro Pertini Hospital, 00157 Rome, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7266-8355","authenticated-orcid":false,"given":"Antonella","family":"Guarino","sequence":"additional","affiliation":[{"name":"Physiopathology of Reproduction and Andrology Unit, Sandro Pertini Hospital, 00157 Rome, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Caterina","family":"Meneghini","sequence":"additional","affiliation":[{"name":"Physiopathology of Reproduction and Andrology Unit, Sandro Pertini Hospital, 00157 Rome, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2872-4425","authenticated-orcid":false,"given":"Emanuele","family":"Licata","sequence":"additional","affiliation":[{"name":"Physiopathology of Reproduction and Andrology Unit, Sandro Pertini Hospital, 00157 Rome, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2202-9720","authenticated-orcid":false,"given":"Gemma","family":"Paciotti","sequence":"additional","affiliation":[{"name":"Physiopathology of Reproduction and Andrology Unit, Sandro Pertini Hospital, 00157 Rome, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Donatella","family":"Miriello","sequence":"additional","affiliation":[{"name":"Physiopathology of Reproduction and Andrology Unit, Sandro Pertini Hospital, 00157 Rome, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michele Carlo","family":"Schiavi","sequence":"additional","affiliation":[{"name":"Department of Obstetrics and Gynecology, Sandro Pertini Hospital, 00157 Rome, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5652-5875","authenticated-orcid":false,"given":"Vincenzo","family":"Spina","sequence":"additional","affiliation":[{"name":"Protection of Maternal and Child Health Unit, 02100 Rieti, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Roberta","family":"Corno","sequence":"additional","affiliation":[{"name":"Physiopathology of Reproduction and Andrology Unit, Sandro Pertini Hospital, 00157 Rome, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mariagrazia","family":"Gallo","sequence":"additional","affiliation":[{"name":"Physiopathology of Reproduction and Andrology Unit, Sandro Pertini Hospital, 00157 Rome, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rocco","family":"Rago","sequence":"additional","affiliation":[{"name":"Physiopathology of Reproduction and Andrology Unit, Sandro Pertini Hospital, 00157 Rome, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,11,21]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"The ESHRE Guideline Group on Female Fertility Preservation, Anderson, R.A., Amant, F., Braat, D., D\u2019Angelo, A., Chuva de Sousa Lopes, S.M., Demeestere, I., Dwek, S., Frith, L., and Lambertini, M.
