Proceedings of the Working Group Session on Fertility Preservation for Individuals with Gender and Sex Diversity

Children and adolescents with gender and sex diversity include (1) gender-nonconforming and transgender individuals for whom gender identity or expression are incongruent with birth-assigned sex (heretofore, transgender) and (2) individuals who have differences in sex development (DSD). Although these are largely disparate groups, there is overlap in the medical expertise necessary to care for individuals with both gender and sex diversity. In addition, both groups face potential infertility or sterility as a result of desired medical and surgical therapies. The Ann and Robert H. Lurie Children's Hospital of Chicago (Lurie Children's) gender and sex development program (GSDP) provides specialized multidisciplinary care for both transgender and DSD patients. In response to patient concerns that recommended medical treatments have the potential to affect fertility, the Lurie Children's GSDP team partnered with experts from the Oncofertility Consortium at Northwestern University to expand fertility preservation options to gender and sex diverse youth. This article summarizes the results of a meeting of experts across this field at the annual Oncofertility Consortium conference with thoughts on next steps toward a unified protocol for this patient group.Peer Reviewedhttps://deepblue.lib.umich.edu/bitstream/2027.42/140296/1/trgh.2016.0008.pd

Prevention of Growth Failure in Turner Syndrome: Long-Term Results of Early Growth Hormone Treatment in the “Toddler Turner” Cohort

Introduction: In the randomized “Toddler Turner” study, girls who received growth hormone (GH) starting at ages 9 months to 4 years (early-treated [ET] group) had marked catch-up growth and were 1.6 ± 0.6 SD taller than untreated (early-untreated [EUT]) control girls after 2 years. However, whether the early catch-up growth would result in greater near-adult height (NAH) was unknown. Therefore, this extension study examined the long-term effects of toddler-age GH treatment on height, pubertal development, and safety parameters. Methods: Toddler Turner study participants were invited to enroll in a 10-year observational extension study for annual assessments of growth, pubertal status, and safety during long-term GH treatment to NAH for both ET and EUT groups. Results: The ET group was taller than the EUT group at all time points from preschool to maturity and was significantly taller at the onset of puberty (p = 0.016), however, the difference was not significant at NAH. For the full cohort (ET + EUT combined, n = 50) mean (± SD) NAH was 151.2 ± 7.1 cm at age 15.0 ± 1.3 years. NAH standard deviation score (SDS) was within the normal range (>−2.0) for 76% of ET and 60% of EUT subjects (68% overall) and correlated strongly with height SDS at GH start (r = 0.78; p < 0.01), which in turn had a modest inverse correlation with age at GH start (i.e., height SDS declined with increasing age in untreated girls [r = −0.30; p = 0.016]). No new safety concerns arose. Conclusion: Although the ET group was taller throughout, height SDS at NAH was not significantly different between groups due to catch-down growth of ET girls during lapses in GH treatment after the Toddler study and similar long-term GH exposure overall. Early initiation of GH by age 6 years, followed by uninterrupted treatment during childhood, can prevent ongoing growth failure and enable attainment of height within the normal range during childhood, adolescence, and adulthood

A View from the Past Into our Collective Future: The Oncofertility Consortium Vision Statement

Today, male and female adult and pediatric cancer patients, individuals transitioning between gender identities, and other individuals facing health extending but fertility limiting treatments can look forward to a fertile future. This is, in part, due to the work of members associated with the Oncofertility Consortium. The Oncofertility Consortium is an international, interdisciplinary initiative originally designed to explore the urgent unmet need associated with the reproductive future of cancer survivors. As the strategies for fertility management were invented, developed or applied, the individuals for who the program offered hope, similarly expanded. As a community of practice, Consortium participants share information in an open and rapid manner to addresses the complex health care and quality-of-life issues of cancer, transgender and other patients. To ensure that the organization remains contemporary to the needs of the community, the field designed a fully inclusive mechanism for strategic planning and here present the findings of this process. This interprofessional network of medical specialists, scientists, and scholars in the law, medical ethics, religious studies and other disciplines associated with human interventions, explore the relationships between health, disease, survivorship, treatment, gender and reproductive longevity. The goals are to continually integrate the best science in the service of the needs of patients and build a community of care that is ready for the challenges of the field in the future

Can the external masculinization score predict the success of genetic testing in 46,XY DSD?

Genetic testing is judiciously applied to individuals with Disorders of Sex Development (DSD) and so it is necessary to identify those most likely to benefit from such testing. We hypothesized that the external masculinization score (EMS) is inversely associated with the likelihood of finding a pathogenic genetic variant. Patients with 46,XY DSD from a single institution evaluated from 1994-2014 were included. Results of advanced cytogenetic and gene sequencing tests were recorded. An EMS score (range 0-12) was assigned to each patient according to the team's initial external genitalia physical examination. During 1994-2011, 44 (40%) patients with 46,XY DSD were evaluated and underwent genetic testing beyond initial karyotype; 23% (10/44) had a genetic diagnosis made by gene sequencing or array. The median EMS score of those with an identified pathogenic variant was significantly different from those in whom no confirmed genetic cause was identified [median 3 (95% CI, 2-6) versus 6 (95% CI, 5-7), respectively (p = 0.02)], but limited to diagnoses of complete or partial androgen insensitivity (8/10) or 5-reductase deficiency (2/10). In the modern cohort (2012-2014), the difference in median EMS in whom a genetic cause was or was not identified approached significance (p = 0.05, median 3 (95% CI, 0-7) versus 7 (95% CI, 6-9), respectively). When all patients from 1994-2014 are pooled, the EMS is significantly different amongst those with compared to those without a genetic cause (median EMS 3 vs. 6, p &lt; 0.02). We conclude that an EMS of 3 or less may indicate a higher likelihood of identifying a genetic cause of 46,XY DSD and justify genetic screening, especially when androgen insensitivity is suspected

Growth Hormone Treatment Does Not Affect Incidences of Middle Ear Disease or Hearing Loss in Infants and Toddlers with Turner Syndrome

No randomized, controlled, prospective study has evaluated the effect of growth hormone (GH) on the rates of middle ear (ME) disease and hearing loss in girls with Turner syndrome (TS)

Gender destinies: assigning gender in Disorders of Sex Development-Intersex clinics.

Based on audio recordings of consultations in three U.S. paediatric multidisciplinary Disorders of Sex Development‐Intersex clinics, we examine the process of gender assignment of children with “atypical” genitalia. Rather than fully determined by the presence of biological sex traits, the gender assignment discussion hinges on how clinician and parent collaboratively imagine different aspects of what constitutes being a gendered person. They orient towards the potential for sexual intimacy, fertility, gender dysphoria, stigma, and gonadal cancer risk. While these futures remain inherently uncertain, clinicians and parents plan to mobilise gender socialisation and medical interventions to render their choice of gender a self‐fulfilling prophecy. Gender destinies capture that the child always had a specific, innate gender awaiting discovery, and presumes a project for medical and social monitoring, intervention, correction, and optimisation.Peer Reviewedhttps://deepblue.lib.umich.edu/bitstream/2027.42/153282/1/shil12974.pdfhttps://deepblue.lib.umich.edu/bitstream/2027.42/153282/2/shil12974_am.pd
