Abstract STUDY QUESTION What is the fertility preservation (FP) utilization rate among transgender and gender diverse (TGD) patients at the Transgender and Intersex Specialty Care Clinic (TISCC) within the Mayo Clinic? SUMMARY ANSWER The rate of utilization of FP services by TGD patients at Mayo Clinic’s TISCC was determined to be 6.62%. WHAT IS KNOWN ALREADY TGD patients encounter several barriers when pursuing FP, which may contribute to a lower utilization rate of these services. These barriers include financial constraints and lack of insurance coverage, as well as societal and healthcare provider attitudes; TGD individuals face discrimination or lack of understanding, making it uncomfortable or difficult to discuss FP options. Additionally, there continues to be a lack of inclusive policies and support within healthcare systems that can further impede access to FP services for TGD individuals. STUDY DESIGN, SIZE, DURATION The study was executed in two phases. In the first phase, a retrospective cohort study was completed with TGD patients who provided electronic health record (EHR) research authorization from Mayo Clinic’s TISCC in Rochester, MN between 1 January 2015 and 30 July 2021. Search terms related to FP were used to determine the FP utilization rate among this patient population. In the second phase of the study, two sets of patients, (i) patients who were included in the cohort study in Phase 1, and (ii) members of JASMYN, a community organization specializing in care and wellness coordination for Lesbian, Gay, Bisexual, and Transgender (LGBT) teens and young adults in North Florida. Individuals were invited to participate in a qualitative interview exploring their cumulative healthcare experiences accessing gender-affirming care. Interviews were conducted from January 2023 to June 2023. Interviews examined participants’ perceptions of FP options, motivations for pursuing FP, and barriers to accessing both gender and fertility care. When applicable, participants also discussed their experiences pursuing FP and reflected on their satisfaction with their fertility and family planning decisions. PARTICIPANTS/MATERIALS, SETTING, METHODS In phase 1, a total of N = 1189 patients sought care from Mayo Clinic’s TISCC in Rochester, MN. Out of these patients, N = 589 patients provided research authorization and were included in the retrospective cohort study. The study team assessed whether FP terms were mentioned in each patient’s EHR, and whether patients scheduled and attended appointments with either the Department of Reproductive Endocrinology or the Department of Urology. FP search terms included sperm cryopreservation, sperm extraction, sperm aspiration, testicular tissue cryopreservation, oocyte cryopreservation, embryo cryopreservation, and ovarian tissue cryopreservation. In phase 2, N = 36 participants were interviewed, with N = 25 participants recruited from Mayo Clinic’s TISCC in Rochester, MN, and N = 11 participants recruited from JASMYN in Jacksonville, FL. Participants recruited from the Mayo Clinic participated in a video-call-based interview and those enrolled from JASMYN were interviewed in person. MAIN RESULTS AND THE ROLE OF CHANCE The study team observed a 6.62% utilization rate of FP services among N = 589 patients (median age: 28 years; age range: 8–78 years) included in the retrospective cohort study. N = 39 patients completed FP, with N = 14 receiving these services at other institutions before seeking care with the TISCC at Mayo Clinic. N = 25 patients pursued FP services within the Mayo Clinic. Patients with testes were more likely to complete FP via sperm cryopreservation when compared to the utilization of egg cryopreservation among patients with ovaries. Participants who completed an interview in Phase 2 (median age 27 years; age range: 22–80 years) reflected on their decision on whether to preserve their fertility and what factors influenced these decisions, and how their satisfaction with this decision has changed over their lifespan. The major themes reported here include the desire for biological children, planning gender care around fertility desires, conversations about FP options, physical and psychosocial barriers to pursuing FP, reflections on personal FP decisions, and reflections on having to make decisions about FP at a young age. LIMITATIONS, REASONS FOR CAUTION All participants who completed an interview have done so voluntarily; as such, there is a possibility of selection and recall bias. WIDER IMPLICATIONS OF THE FINDINGS Findings suggest that there is a need for more structured conversations around FP when TGD patients seek medical and surgical gender-affirming care. Accessibility, including financial barriers and limited insurance coverage, continues to limit the utilization of FP services among TGD patients. Increased affordability through insurance coverage may additionally improve FP utilization.

Introduction: Underrepresented in family medicine (URiFM) physicians hold 14.42% of US family medicine faculty positions. Scholarship is critical to academic advancement. We explored family medicine department chairs’ racial allyship, their identification of scholarship barriers faced by URiFM faculty, and the existence of initiatives to increase scholarship. Methods: We used the 2022 Council of Academic Family Medicine Educational Research Alliance (CERA) Department Chair survey to examine the percentage of chair-perceived URiFM departmental faculty members and their scholarly productivity and chair-perceived barriers to productivity and initiatives. We measured chairs’ racial allyship. We calculated descriptive statistics, weighted means, and used regression to identify whether chair characteristics or allyship scores were associated with support of URiFM faculty scholarship initiatives and identification of the minority tax. Results: One hundred nine chairs completed the survey (response rate 48.4%); 13.76% identified as URiFM; 6.4% reported they perceived more than 50% of their faculty were URiFM; 90.8% of chairs did not report programs supporting URiFM scholarship; and 44.9% described URiFM faculty scholarly output as minimal or none. Department chairs’ mean allyship score was 2.59 (SD = 0.80) out of 5. Chairs ranked lack of research skills and lack of funding for protected time higher than the minority tax from a list of scholarship barriers. We found no association between chair allyship scores, chair characteristics, total department full-time equivalents, and the existence of a URiFM faculty scholarly support program. Discussion: Despite chairs reporting low URiFM faculty scholarly output, few departments have a dedicated support program. Chair allyship scores were not associated with identification of scholarship barriers or existence of scholarship programs.

Abstract Background Medical chaperones are authorized individuals present during physical examinations involving the genitals, breasts/chest, or anal areas. The use of medical chaperones may provide an opportunity to improve transgender and gender diverse (TGD) patients’ experiences with sensitive examinations. Aim To examine TGD adult patients’ preferences and comfort for having a medical chaperone and whether TGD-specific characteristics, social anxiety symptoms, and feelings of medical mistrust are associated with preference for having a medical chaperone present during a sensitive physical examination. Methods This study used a cross-sectional survey that randomly sampled adult patients from a gender clinic in the Midwest region of the U.S. A total of 420 surveys were mailed. Sixty-two surveys were returned undeliverable, 358 reached recipients; 151 were returned (42.1% response rate). The survey included items related to demographics, gender-related anatomical dysphoria, social anxiety symptoms, feelings of medical mistrust, and preference and comfort towards medical chaperones. Results Among 149 respondents, 74 (49.7%) reported comfort for the idea of having a medical chaperone present during a sensitive physical examination, 50 (33.6%) reported neutral comfort, and 25 (16.8%) reported discomfort. Among 147 respondents, 89 (60.5%) endorsed a preference for a female medical chaperone. We found no associations between gender-related anatomical dysphoria or social anxiety symptoms and comfort for having a medical chaperone, or the gender preference for a medical chaperone. Medical mistrust was associated with lower comfort with having a medical chaperone present during a sensitive physical examination. Clinical Implications Routinely offering medical chaperones, especially female chaperones, is like to be generally acceptable to most TGD patients. These findings may inform clinic policies on providing medical chaperones during sensitive examinations. Strengths and Limitations This study is the first to examine TGD preferences for medical chaperones. Findings are limited by a single site, homogeneous sample, cross-sectional design, and reliance on hypothetical rather than observed examinations. Conclusion TGD adults report comfort with the concept of having a medical chaperone during sensitive examinations and most would prefer the chaperone to be female. Preference for having a medical chaperone present during a sensitive physical exam is not likely influenced by gender dysphoria or social anxiety.

Background and Objectives: Faculty members who are underrepresented in medicine (URM) may benefit from mentorship that is designed specifically to meet their unique needs and is focused on improving their career pathways in academic medicine. The Underrepresented in Medicine Mentorship Program (URM-MP) is an academic society-based mentorship program that pairs early career URM faculty with mid- to late-career faculty specifically trained to address URM issues. Methods: During the first 3 years of the program, mentors received web-based training on addressing oppression and marginalization of URM faculty in academic medicine. Mentor and mentee pairs met monthly for 1 year and received support from program leaders through web-based check-in meetings twice per year. Pre- and postassessment data were collected from mentees to help identify their needs and evaluate their experiences. Check-in meetings provided feedback about the program. Results: Fifty-seven URM faculty participated in years 1, 2, and 3. Results of pre- and postsurveys showed that mentees significantly improved their self-perceived effectiveness to enhance their careers, to find resources to perform their jobs, and to navigate the challenges of advancing in academic medicine. Qualitative analyses revealed themes of appreciation for mentors supporting their unique experiences as URM faculty. Check-in feedback further reinforced the relationship aspects of the mentorship as a significant benefit of this program. Conclusions: Society-based mentorship that involves specific training for mentors and fosters trusting mentor-mentee relationships can improve URM faculty’s confidence regarding their ability to succeed in academic medicine.

AbstractObjectiveTransgender and gender‐diverse (TGD) individuals have a gender identity or expression that differs from the sex assigned to them at birth. They are an underserved population who experience health care inequities. Our primary objective was to identify if there are treatment differences between TGD and cisgender lesbian/gay/bisexual/queer (LGBQ) or heterosexual individuals presenting with abdominal pain to the emergency department (ED).MethodsRetrospective observational cohort study of patients ≥12 years of age presenting to 21 EDs within a health care system with a chief complaint of abdominal pain between 2018 and 2022. TGD patients were matched 1:1:1:1 to cisgender LGBQ women and men and cisgender heterosexual women and men, respectively. Propensity score matching covariates included age, ED site, mental health history, and gastrointestinal history. The primary outcome was pain assessment within 60 min of arrival. The secondary outcome was analgesics administered in the ED.ResultsWe identified 300 TGD patients, of whom 300 TGD patients were successfully matched for a total cohort of 1300 patients. The median (IQR) age was 25 (20–32) years and most patients were treated in a community ED (58.2%). There was no difference between groups in pain assessment within 60 min of arrival (59.0% TGD vs. 63.2% non TGD, p = 0.19). There were no differences in the number of times pain was assessed (median [IQR] 2 [1–3] vs. 2 [1–4], p = 0.31) or the severity of pain between groups (5.5 [4–7] vs. 6 [4–7], p = 0.11). TGD patients were more likely to receive nonsteroidal anti‐inflammatory drugs (32.0% vs. 24.9%, p = 0.015) and less likely to receive opioids than non‐TGD patients (24.7% vs. 36.9%, p = <0.001). TGD and nonbinary patients, along with LGBQ cisgender women (24.7%) and heterosexual cisgender women (34%), were less likely to receive opioids than LGBQ cisgender men (54%) and heterosexual cisgender men (42.3%, p < 0.01).ConclusionThere was no difference in frequency of pain assessment, regardless of gender identity or sexual orientation. More cisgender men, compared to TGD and cisgender women, received opioids for their pain.

Abstract Context Transgender and gender diverse (TGD) individuals have greater access to genital surgery (GS) with improved insurance coverage and access to trained surgeons and interdisciplinary gender-affirming providers. Objective To determine perioperative medical and behavioral health outcomes in transfeminine (TF) individuals undergoing GS, with use of a specific gender-affirming hormone therapy (GAHT) algorithm based on individualized risk factor assessment. Methods In this retrospective observational cohort study, we collected preoperative and postoperative data from 183 TF individuals at a single tertiary referral center from 2017 to 2022, grouping patients by those who continued estradiol (Group 1) vs those who had temporarily discontinued estradiol for 2 to 6 weeks preoperatively (Group 2). Data included clinical and biochemical assessment, GAHT regimens, validated behavioral health measures, and postoperative complications. Main outcomes included venous thromboembolism (VTE) incidence, non-VTE postoperative complication incidence, and change in behavioral health assessments. Results The majority of individuals continued estradiol perioperatively (Group 1; 138 [75.4%]). Individuals who temporarily held estradiol preoperatively (Group 2; 45 [24.6%]) were statistically older (P &lt; .01), had higher incidence of cardiometabolic comorbidities (P &lt; .01), and higher Caprini scores (P &lt; .01). Group 1 was statistically more likely to use oral estradiol (P &lt; .01). One episode (0.05%) of VTE occurred (Group 1). There was no significant difference in postoperative complications or behavioral health measures between groups. Conclusion An individualized algorithm for preoperative hormone management for TF GS resulted in perioperative continuation of GAHT for the majority of individuals without significantly increasing the risk for postoperative surgical complications, while maintaining stable behavioral health measures perioperatively.

Introduction: More than 50% of primary care physicians’ practice involves sedentary desk work. Growing evidence suggests a link between sedentary workplace behaviors and increased morbidity and mortality. Research on the effects of sit-stand desks in the workplace suggests that sit-stand desks reduce sedentary behaviors. This study examined the use and satisfaction of adjustable desks with a height of sit-stand and their association with physical self-care behaviors among family medicine residents. Methods: We conducted a longitudinal cohort survey study at a 9-9-9 family medicine residency after the clinic installed height-adjustable sit-stand desks in January 2020. Standardized questions about the use and satisfaction of adjustable sit-stand desks and physical self-care behaviors were administered in June 2020, December 2020, and December 2021. The survey also included an open text box for feedback. Results: Median time spent standing at the sit-stand desks was 55.0%. The percentage of time standing was similar across June 2020, December 2020, and December 2021. The average satisfaction rate with the desks across all time points was 71.4%. We did not observe significant differences in the proportion of residents’ satisfaction with the adjustable desks over time. Residents who reported standing at the adjustable desk reported increased satisfaction with the desks (Kendall’s τ=.38, P&lt;.001) and with physical self-care behaviors (Kendall’s τ=.25, P&lt;.05). Themes associated with desk dissatisfaction revolved around limited desktop space. Conclusion: Over a nearly 1.5-year period, more than half of family medicine residents reported standing at their adjustable desks and being satisfied with them. Residents who reported standing at adjustable desks also reported increased physical self-care behaviors. Residency programs investing in sit-stand desks may consider options that allow for increased desktop surface space.

Introduction: Transgender and gender diverse individuals may choose to provide their infants with human milk. Lactating transgender men may experience gender dysphoria and desire to initiate or reinitiate gender-affirming testosterone therapy. However, there is limited safety data regarding use of testosterone during lactation. Main Issue: A 30-year-old G2P2 transgender man with gender dysphoria sought to initiate gender-affirming testosterone therapy while lactating. Management: Subcutaneous testosterone was self-administered beginning at 13 months post-partum. We prospectively collected data on circulating testosterone concentrations in parent serum, milk, and infant serum over 5 months until the infant self-weaned. The infant was monitored for growth and development at routine pediatric outpatient appointments. Parent serum testosterone concentrations rose with the initiation of testosterone therapy, reaching therapeutic concentrations by Day 14. Milk testosterone concentrations also increased with a maximum concentration of 35.9 ng/dl when the lactating parent was on a dose of 80 mg subcutaneous testosterone cypionate weekly. The calculated milk/plasma ratio remained under 1.0 and the calculated relative infant dose remained under 1%. The infant had no observable side effects, and his serum testosterone concentrations remained undetectable throughout the study period. Conclusion: This is the first study with data regarding human milk and infant serum testosterone concentrations during the initiation of gender-affirming testosterone therapy in a lactating individual. This evidence can help families and clinicians with decisions regarding lactation and testosterone use.

An estimated 1.4 million transgender adults live in the United States; this equates to approximately 0.6% of the U.S. population (Lane et al., 2018). Clinical focus on gender dysphoria has significantly increased over the past 30 years (MacCarthy, Reisner, Nunn, Perez-Brumer, & Operario, 2015), with burgeoning evidence from across disciplines documenting the positive outcomes associated with gender-affirming interventions. The purpose of this article is to illustrate how RNs optimize psychosocial, hormonal, and surgical gender-affirming care through performing comprehensive assessments, coordinating care, and providing education and health coaching.
