By challenging the accepted positions on practices such as elective egg freezing and gamete donation, it has become evident that the arguments are flawed. First, elective egg freezing does not promote or hinder women's emancipation. It could even be argued that elective egg freezing is a consequence of the successful emancipation of the group of highly educated women who, as a result, can inadvertently no longer find the right partner. Second, openness and donor identifiability are presented as progress in gamete donation. This places undue emphasis on a bionormative ideology that runs counter to the core principles of gamete donation. It attributes great value to genetic relationships rather than focusing on social relationships. However, given the importance that Western societies attach to this ideology, some donor-conceived persons are harmed and their well-being is negatively affected. This, in turn, generates a moral obligation for would-be parents to try to have genetically related children.</div></div>","PeriodicalId":21134,"journal":{"name":"Reproductive biomedicine online","volume":"50 4","pages":"Article 104793"},"PeriodicalIF":3.7,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143863678","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Psychosocial models within positive psychology support the intrinsic benefit and adaptative effect of the action of undergoing IVF on well-being and mental health through the opportunity it affords people to achieve, accept and make meaning of their (un)realized parenthood goals. The PERMA model was used to explore the concept of happiness, with evidence showing that happiness can be achieved in IVF via positive emotions (most investigated), a sense of being engaged, positive relationships, and a sense of meaning and accomplishment. The positive lived experience of IVF can be moderated by individual patient characteristics, and enhanced by positive-focused approaches to care.

While randomized controlled trials (RCT) remain the gold standard for providing evidence and for establishing causality, their limitations, including restricted generalizability and high costs, highlight the need for complementary methodologies. Real-world evidence (RWE), derived from real-world data (RWD) such as electronic health records and assisted reproductive technology (ART) registries, has the potential to bridge the gap between controlled research settings and routine clinical practice, particularly for evaluating long-term and rare outcomes. However, RWE faces considerable challenges, including bias, variability in data quality, and difficulties in establishing causality. This paper explores the role of RWE in ART. Despite its promise, RWE cannot replace RCT, particularly in scenarios where the signal-to-noise ratio is low, such as detecting small effect differences in ovarian stimulation protocols or treatment add-ons. Instead, in most instances, RWE is positioned to complement RCT, supported by emerging regulatory frameworks such as the guidelines of the European Medicine Agency and the European Union's tissue directives, which emphasize the generation of RWE from ART practice to strengthen patient follow-up and safety monitoring. For ART stakeholders, a comprehensive understanding of the strengths and limitations of RWE is essential, as is the target trial emulation framework on RWD, for advancing the field and improving patient outcomes.</div></div>","PeriodicalId":21134,"journal":{"name":"Reproductive biomedicine online","volume":"50 4","pages":"Article 104807"},"PeriodicalIF":3.7,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143863682","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This brief review highlights the key stages in oocyte development, as well as recent findings that continue to inform on how the oocyte is able to maintain function over such a prolonged period. These include minimizing oocyte damage caused by the production of reactive oxygen species, the importance of intercellular communication with the surrounding somatic cells, and the molecular mechanisms that underpin the fidelity of chromosome cohesion and then separation at the resumption of meiosis.

Today, PGT is widely accepted and integrated into fertility care in many countries around the world. Its history, however, has not been without controversy, with debate around its application to the diagnosis of late-onset disorders, conditions with incomplete penetrance and its use for embryo selection based upon human leukocyte antigen status. Nonetheless, PGT has progressively broadened its scope, and the number of embryos undergoing genetic testing continues to grow each year. Preimplantation genetic testing is most often used for the detection of chromosomal abnormalities, assisting in the identification of embryos affected by lethal aneuploidy. This application has generated the greatest debate of all, owing, in part, to difficulties delivering effective embryo testing using earlier methods. In recent years, advances in technology and rigorous validation studies have helped to improve accuracy, although variability among methods underscores the need for greater standardization and transparency. Emerging technologies, such as whole genome sequencing (WGS) and genome editing, hold promise for further advancements but introduce complex ethical, privacy and consent challenges that demand careful consideration, public engagement and thorough clinical research before implementation. Given its current trajectory, it seems likely that the use of PGT will continue to grow, offering reduced reproductive risks and the possibility of enhanced fertility treatment outcomes for ever greater numbers of patients, ultimately becoming an accepted cornerstone of reproductive care.</div></div>","PeriodicalId":21134,"journal":{"name":"Reproductive biomedicine online","volume":"50 4","pages":"Article 104845"},"PeriodicalIF":3.7,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143863693","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
