Introduction: Incidence rates for cancer among adolescent and young adults (AYA) have increased 30% since 1970. Declines in mortality underscore the importance of discussing fertility preservation (FP) options prior to receiving gonadotoxic treatments. National guidelines outline FP options including oocyte (OC), embryo (EC), and ovarian tissue cryopreservation (OTC) for female AYA patients. Significant progress has led to changes in FP practices, initially limited to EC. Subsequently, OC was deemed non-experimental in 2013, followed by OTC in 2020. Despite these advancements and guideline recommendations, the availability and utilization of FP services vary.
Areas Covered: Rapid review methodologies were employed to classify trends in female AYAs utilization of FP cryopreservation options following guideline updates. FP options reviewed include OC, EC, and OTC. Additionally, the review examined if aspects of the decision-making process relevant to FP were present.
Expert Opinion: Ten articles met inclusion criteria. Results suggest that the declassification of OTC has not necessarily increased its use and OC and EC appear to be most frequently used. The factors associated with decision making appear to have remained consistent with financial constraints having the most impact, followed by partner status and concerns about recurrence.

Background: To assess the effectiveness of tumor biomarkers in distinguishing epithelial ovarian tumors (EOTs) and guiding clinical decisions across each Ovarian-Adnexal Reporting and Data System (O-RADS) MRI risk category, the aim is to prevent unnecessary surgeries for benign lesions, avoid delays in treating malignancies, and benefit individuals requiring fertility preservation or those intolerant to over-extensive surgery.
Methods: A total of 54 benign, 104 borderline, and 203 malignant EOTs (BeEOTs, BEOTs and MEOTs) were enrolled and retrospectively assigned risk scores. The role of tumor biomarkers in diagnosing and managing EOTs within each risk category was evaluated by combining receiver operating characteristic (ROC) curves with clinicopathological characteristics.

Purpose: This study is to evaluate duration of oocyte cryostorage and association with thaw survival, fertilization, blastulation, ploidy rates, and pregnancy outcomes in patients seeking fertility preservation.
Methods: Retrospective cohort study to evaluate clinical outcomes in patients who underwent fertility preservation from 2011 to 2023 via oocyte vitrification for non-oncologic indications. Primary outcome was thaw survival rate.

Ovarian tissue cryopreservation and transplantation has emerged as a promising fertility preservation technique for individuals facing premature ovarian insufficiency due to various medical conditions or treatments. Xenotransplantation, involving the transplantation of ovarian tissue into animal hosts, has played a pivotal role in refining ovarian tissue cryopreservation and transplantation techniques and addressing key challenges. This review provides a comprehensive overview of the current landscape of ovarian tissue xenotransplantation research, focusing on its applications in investigating ovarian biology, optimizing ovarian tissue cryopreservation and transplantation protocols, and assessing safety concerns.

Background: Mate-pair sequencing detects both balanced and unbalanced structural variants (SVs) and simultaneously informs in relation to both genomic location and orientation of SVs for enhanced variant classification and clinical interpretation, while chromosomal microarray analysis (CMA) only reports deletion/duplication. Herein, we evaluated its diagnostic utility in a prospective back-to-back prenatal comparative study with CMA.
Methods: From October 2021 to September 2023, 426 fetuses with ultrasound anomalies were prospectively recruited for mate-pair sequencing and CMA in parallel for prenatal genetic diagnosis.
