REPRODUCTIVE HEALTH IN TRANS AND GENDER DIVERSE PATIENTS: Mind the gap: a nationwide audit of LGBTQ+ inclusion in fertility care providers in the United Kingdom.

In brief: We describe a first-of-its-kind audit of LGBTQ+ inclusivity in fertility care providers across the United Kingdom. Despite efforts being made to improve LGBTQ+ inclusion in fertility care, our results paint a picture of widespread gaps in clinical and cultural expertise alongside significant barriers to LGBTQ+ inclusion. Abstract: LGBTQ+ patients comprise one of the fastest-growing user demographics in fertility care, yet they remain under-represented in fertility research, practice, and discourse. Existing studies have revealed significant systemic barriers, including cisheteronormativity, discrimination, and gaps in clinical expertise. In this article, we present a checklist of measures that clinics can take to improve LGBTQ+ inclusion in fertility care, co-created with members of the LGBTQ+ community. This checklist focuses on three key areas: cultural competence, clinical considerations, and online presence. The cultural competence criteria encompass inclusive communication practices, a broad understanding of LGBTQ+ healthcare needs, and knowledge of treatment options suitable for LGBTQ+ individuals. Clinical considerations include awareness of alternative examination and gamete collection techniques for transgender and gender diverse patients, the existence of specific clinical pathways for LGBTQ+ patients, and sensitivity to the psychological aspects of fertility care unique to this demographic. The online presence criteria evaluate provider websites for the use of inclusive language and the availability of LGBTQ+-relevant information. The checklist was used as the foundation for an audit of fertility care providers across the UK in early 2024. Our audit identified a widespread lack of LGBTQ+ inclusion, particularly for transgender and gender diverse patients, highlighting deficiencies in clinical knowledge and cultural competence. Our work calls attention to the need for further efforts to understand the barriers to inclusive and competent LGBTQ+ fertility care from both healthcare provider and patient perspectives.

Perivitelline threads associated with fragments in human cleavage stage embryos observed through time-lapse microscopy.

Perivitelline threads (PVT) are defined as thin filaments that extend across the perivitelline space connecting the zona pellucida with the oolemma or, in some cases, blastomere membrane. This is the first report of PVT in human embryos. Time-lapse imagery from 525 blastocysts with either tested ploidy, known implantation status, or both, were reviewed for the presence of PVT, the cell stage when PVT were first observed, association with fragmentation, ploidy or implantation potential; PVT were observed in most embryos (404/525 [77%]). The euploidy rate was similar in embryos with PVT (61/152 [40%]) and without PVT (17/35 [49%]). Implantation rates were also similar in embryos with PVT (64/259 [25%]) and without PVT (25/90 [28%]). In the embryos in which PVT were observed, 98% (396/404) developed at the two-cell stage. In most embryos (384/404 [95%]), PVT were observed to directly pull fragments from the embryo. Fragmentation occurred significantly less frequently in embryos without PVT compared with PVT (81/121 [67%] versus 388/404 [96%]; P < 0.001). These data suggest an association between PVT and fragmentation. This study is limited in that PVT were not characterized so their nature and origin remain unknown and to be determined in future studies.
