Fertility Counseling for Transgender Adolescents: A Review

[Beyond NICE: Updated Systematic Review on the Current Evidence of Using Puberty Blocking Pharmacological Agents and Cross-Sex-Hormones in Minors with Gender Dysphoria]

Beyond NICE: Updated Systematic Review on the Current Evidence of Using Puberty Blocking Pharmacological Agents and Cross-Sex-Hormones in Minors with Gender Dysphoria Abstract: Objective: The suppression of physiological puberty using puberty-blocking pharmacological agents (PB) and prescribing cross-sex hormones (CSH) to minors with gender dysphoria (GD) is a current matter of discussion, and in some cases, PB and CSH are used in clinical practice for this particular population. Two systematic reviews (one on PB, one on CSH treatment) by the British National Institute for Clinical Excellence (NICE) from 2020 indicated no clear clinical benefit of such treatments regarding critical outcome variables. In particular, these two systematic NICE reviews on the use of PB and CSH in minors with GD detected no clear improvements of GD symptoms. Moreover, the overall scientific quality of the available evidence, as discussed within the above-mentioned two NICE reviews, was classified as "very low certainty" regarding modified GRADE criteria. Method: The present systematic review presents an updated literature search on this particular topic (use of PB and CSH in minors with GD) following NICE principles and PICO criteria for all relevant new original research studies published since the release of the two above-mentioned NICE reviews (updated literature search period was July 2020-August 2023). Results: The newly conducted literature search revealed no newly published original studies targeting NICE-defined critical and important outcomes and the related use of PB in minors with GD following PICO criteria. For CSH treatment, we found two new studies that met PICO criteria, but these particular two studies had low participant numbers, yielded no significant additional clear evidence for specific and clearly beneficial effects of CSH in minors with GD, and could be classified as "low certainty" tfollowing modified GRADE criteria. Conclusions: The currently available studies on the use of PB and CSH in minors with GD have significant conceptual and methodological flaws. The available evidence on the use of PB and CSH in minors with GD is very limited and based on only a few studies with small numbers, and these studies have problematic methodology and quality. There also is a lack of adequate and meaningful long-term studies. Current evidence doesn't suggest that GD symptoms and mental health significantly improve when PB or CSH are used in minors with GD. Psychotherapeutic interventions to address and reduce the experienced burden can become relevant in children and adolescents with GD. If the decision to use PB and/or CSH is made on an individual case-by-case basis and after a complete and thorough mental health assessment, potential treatment of possibly co-occurring mental health problems as well as after a thoroughly conducted and carefully executed individual risk-benefit evaluation, doing so as part of clinical studies or research projects, as currently done in England, can be of value in terms of generation of new research data.

Fertility preservation discussions, referral and follow-up in male-to-female and female-to-male adolescent transgender patients

The number of patients seeking transgender healthcare is growing, and there is a potential impact of gender-affirming therapies on fertility. The use of fertility preservation (FP), particularly among transgender adolescents, has been limited. We aimed to examine differences in FP counselling, referral and utilisation between male-to-female (MtF) and female-to-male (FtM) transgender adolescents. A retrospective review of the medical records of patients ages 12-17 seen at an academic medical centre between 2012 and 2017 with a diagnosis of gender dysphoria was conducted. A total of 22 MtF and 45 FtM adolescents were included. The counselling on the potential fertility impact of gender-affirming therapy was documented in 55%, and of those counselled, 73% were counselled before receiving medication. There was no significant difference between the timing of counselling for MtF versus FtM adolescents. Of patients with documented reproductive wishes, 77% reported either desire for adopted children or no desire for biological children. Among patients offered FP referral, 2 (22.2%) MtF and 3 (12.5%) FtM patients accepted; both MtF patients cryopreserved sperm. While most adolescents were counselled on the fertility impact of gender-affirming therapy, there is room for improvement as 45% of patients had no documented counselling. The rate of transgender adolescents pursuing FP consultation and gamete cryopreservation was low, consistent with prior studies in this population.

Puberty Assessment and Consideration of Gonadotropin-Releasing Hormone Agonists in Transgender and Gender-Diverse Youth

Transgender and gender-diverse (TGD) youth may pursue gender-affirming medical therapy in the form of gonadotropin-releasing hormone analogues (GnRHa), or "puberty blockers," if pubertal changes result in the development or worsening of gender dysphoria. GnRHa monotherapy can allow TGD youth to explore gender without the distress of unwanted secondary sexual characteristics. However, given the potential effects of GnRHa on growth, skeletal development, neurodevelopment, fertility, and future surgical outcomes, it is critical to accurately assess pubertal status to facilitate fully informed conversations with TGD youth and families about risks, benefits, and unknown consequences of GnRHa monotherapy. The focus of this discussion will be on the approach to puberty assessment in TGD youth as well as the different effects of GnRHa monotherapy that may be important to TGD youth and their families.

Fertility treatment outcomes in transgender men with a history of testosterone therapy

Objective

To evaluate fertility treatment outcomes among transgender (TG) men with a history of gender-affirming hormone therapy with exogenous testosterone.

Design

Descriptive, retrospective cohort study.

Patients

Transgender men with a history of gender-affirming hormone therapy with exogenous testosterone underwent fertility treatments, including embryo cryopreservation, in vitro fertilization (IVF), co-IVF, oocyte cryopreservation, and intrauterine insemination (IUI), between 2013 and 2021.

Intervention

Gender-affirming hormone therapy with testosterone.

Main Outcome Measures

Live births (LBs), number of frozen embryos, and number of frozen oocytes. Other outcome measures included total gonadotropin used, peak estradiol levels, oocytes retrieved, oocyte maturity rate, fertilization rate, and embryo grade.

Results

A total of 77 TG men self-presented or were referred to care at a single academic fertility center, of which 46 (59.7%) TG men underwent fertility preservation and/or family-building counseling, with 16 (20.8%) patients proceeding to fertility treatment. Of those patients who underwent treatment, 11 (68.8%) had a history of gender-affirming hormone therapy with exogenous testosterone use. Cohort 1 included IVF (n = 1), co-IVF (n = 1), embryo cryopreservation (n = 2), cohort 2 included oocyte cryopreservation (n = 4), and cohort 3 included IUI (n = 3). In cohort 1, both the patients who underwent IVF and the patients who underwent co-IVF achieved LBs. All embryo cryopreservation cycles froze three or more embryos. In cohort 2, the average number of frozen mature oocytes was 19.3 ± 16.2 (range 6-43). All patients who underwent IUI cycles achieved LB.

Conclusion

In this study, no correlation existed between patient age, time on or off gender-affirming hormone therapy with exogenous testosterone, total gonadotropin used, and number of oocytes retrieved. All patients who completed IVF or embryo cryopreservation produced high-quality blastocytes, and this is the first study to show successful IUI cycles in patients with a history of gender-affirming hormone therapy with exogenous testosterone. This study demonstrates that TG men who have used gender-affirming hormone therapy previously can successfully undergo fertility treatments to attain oocyte and embryo cryopreservation, pregnancy, and LBs.

Gender-Affirming Surgery in Adolescents and Young Adults: A Review of Ethical and Surgical Considerations

BACKGROUND

The number of transgender adolescents seeking gender-affirming surgery (GAS) in increasing. Surgical care of the adolescent transgender patient is associated with several unique technical, legal, and ethical factors. The authors present a review of the current literature on gender-affirming surgery for individuals under the age of legal majority and propose directions for future research.

METHODS

A scoping review of recent literature was performed to assess evidence on gender-affirming surgery in individuals under the age of legal majority. Articles were included that examined either ethical or technical factors unique to pediatric GAS. Study characteristics and conclusions were analyzed in conjunction with expert opinion.

RESULTS

Twelve articles were identified that met inclusion criteria. Ten of these articles discussed ethical challenges in adolescent GAS, seven discussed legal challenges, and five discussed technical challenges. Ethical discussions focused on the principles of beneficence, nonmaleficence, and autonomy. Legal discussions centered on informed consent and insurance coverage. Technical discussions focused on the effects of puberty blockade on natal tissue.

CONCLUSIONS

Surgical care of the adolescent transgender patient involves important ethical, legal, and technical considerations that must be addressed by the clinical team. As the population of individuals seeking GAS after puberty blockade increases, future research is needed describing functional and psychosocial outcomes in these individuals.

Impaired in vitro fertilization outcomes following testosterone treatment improve with washout in a mouse model of gender-affirming hormone treatment

BACKGROUND

The impact of gender-affirming testosterone on fertility is poorly understood, with ovarian histopathologic studies showing variable results, some with a detrimental effect on reproductive capacity and uncertain reversibility. Assisted reproductive outcome data are restricted to small case series that lack the ability to inform clinical practice guidelines and limit fertility preservation counseling for transgender and nonbinary individuals.

OBJECTIVE

This study aimed to determine the impact of current testosterone and testosterone washout on in vitro fertilization outcomes in a mouse model for gender-affirming hormone treatment. We hypothesized that current or previous testosterone treatment would not affect in vitro fertilization outcomes.

STUDY DESIGN

C57BL/6N female mice (n=120) were assigned to 4 treatment groups: (1) current control, (2) current testosterone, (3) control washout, and (4) testosterone washout. Testosterone implants remained in situ for 6 or 12 weeks, representing the short- and long-term treatment arms, respectively. Current treatment groups underwent ovarian stimulation with implants in place, and washout treatment groups were explanted and had ovarian stimulation after 2 weeks. Oocytes were collected, fertilized, and cultured in vitro, with one arm continuing to the blastocyst stage and the other having transfer of cleavage-stage embryos. Statistical analysis was performed using GraphPad Prism, version 9.0 and R statistical software, version 4.1.2, with statistical significance defined by P<.05.

RESULTS

Current long-term testosterone treatment impaired in vitro fertilization outcomes, with fewer mature oocytes retrieved (13.7±5.1 [standard deviation] vs 28.6±7.8 [standard deviation]; P<.0001) leading to fewer cleavage-stage embryos (12.1±5.1 vs 26.5±8.2; P<.0001) and blastocysts (10.0±3.2 vs 25.0±6.5; P<.0001). There was recovery of in vitro fertilization outcomes following washout in the short-term treatment cohort, with incomplete reversibility in the long-term cohort. Testosterone did not negatively affect maturity, fertilization, or blastulation rates.

CONCLUSION

In a mouse model of gender-affirming hormone treatment, testosterone negatively affected oocyte yield without affecting oocyte quality. Our findings suggest that testosterone reversibility is duration-dependent. These results demonstrate the feasibility of in vitro fertilization without testosterone discontinuation while supporting a washout period for optimization of mature oocyte yield.

Sperm parameters in Israeli transgender women before and after cryopreservation

BACKGROUND

The application of fertility preservation, initially intended for oncological patients prior to gonadotoxic treatment, has extended in recent years to transgender and gender-non-conforming individuals undergoing therapy for gender compatibility.

OBJECTIVES

To examine semen quality and survival in transgender women pursuing semen cryopreservation in the presence or absence of gender-affirming hormonal medication.

MATERIALS AND METHODS

In this retrospective cohort study, we reviewed data of 74 consecutive transgender women presenting for semen cryopreservation at a single center between 2000 and 2019. Semen parameters before and after cryopreservation were compared to a control group composed of 100 consecutive sperm bank donor candidates. A subgroup analysis of subjects who had used gender-affirming hormonal treatment was also performed.

RESULTS

Compared to the control group, transgender women had lower total sperm count (144.0 vs. 54.5 million, respectively, p < 0.001), lower sperm motility percentage (65.0% vs. 51.0%, respectively, p < 0.001), and lower total motile sperm count (94.0 vs. 27.0 million, respectively, p < 0.001). Values were further decreased in transgender women who had received hormonal treatment before sperm cryopreservation. Post-thawing motility rate remained lower in the transgender group compared to the control group (20.0% vs. 45.0%, respectively, p < 0.001), and the total motile count remained lower as well (2.7 vs. 9.0 million, respectively, p < 0.001). Following sperm cryopreservation, the post-thaw decreases in total motile sperm count were higher in the transgender group compared with the control group (91.5% vs. 90.0%). Further subdivision in the transgender group showed that the decrease in total motile sperm count was lower for transgender women who did not use gender-affirming hormonal treatment compared to those who did (-89.7% vs. -92.6%, respectively, p < 0.01).

DISCUSSION AND CONCLUSION

Sperm parameters in transgender women are poor compared to candidates for sperm donation representing the general population. Specimens collected after discontinuation of gender-affirming hormone treatments were further impaired. Moreover, post-thawing sperm total motile count, motility, and overall sperm survival were reduced in transgender women.

Fertility preservation for transgender children and young people in paediatric healthcare: a systematic review of ethical considerations

BACKGROUND

While fertility preservation is recommended practice for paediatric oncology patients, it is increasingly being considered for transgender children and young people in paediatric care. This raises ethical issues for clinicians, particularly around consent and shared decision-making in this new area of healthcare.

METHODS

A systematic review of normative literature was conducted across four databases in June 2020 to capture ethical considerations related to fertility counselling and preservation in paediatric transgender healthcare. The text of included publications was analysed inductively, guided by the Qualitative Analysis Guide of Leuven.

RESULTS

Twenty-four publications were identified for inclusion. Four key ethical considerations emerged from this literature: access to fertility preservation, conscientious objection, decision-making capacity of children and young people, and shared decision-making.

CONCLUSION

In the identified literature, there is consensus that transgender children and young people should not be refused access to fertility preservation services solely due to their gender identity, and that clinicians with conscientious objections to fertility preservation for this group have an obligation to refer on to willing providers. Factors that create ethical complexity in this area of paediatric care include the child's age, mental health, and parents' views.

Fertility Preservation and Reproductive Potential in Transgender and Gender Fluid Population

The gender diverse and transgender community is a minor patient group that is encountered with increasing frequency in the clinical setting, attributed to the improved awareness and access to medical facilities. Partial impairment to permanent elimination of fertility potential and outcomes depending on the treatment modality usually is a result of gender-affirming therapy, which includes both hormone therapy and surgical intervention. Although seldom conducted in the clinical field, transgender patients should be counseled on their fertility preservation options prior to medical and surgical gender transition. There is relatively limited data and clinical information regarding fertility preservation for transgender individuals. Current treatment regimens are based on protocols from fertility preservation after oncological treatments. Major barriers for the transgender population exist due to the lack of information provided and clinical narrative that is not familiar to the physician or health care provider, although there are various options for fertility preservation. A deeper understanding of this clinical agenda and the mandatory processes will ultimately result in a much more comprehensive and specific care for transgender individuals who are in great need for fertility counseling or treatment options that concern fertility preservation. In this review, current clinical approaches will be summarized and fertility preservation options along with ongoing and future clinical trials in fertility preservation for transgender individuals will be thoroughly reviewed.

Fertility preservation in transgender men and the need for uniform, comprehensive counseling

Objective

To review the literature to assess best practices for counseling transgender men who desire gender-affirming surgery on fertility preservation options.

Design

A scoping review of articles published through July 2021.

Setting

None.

Patient(s)

Articles published in Cochrane, Web of Science, PubMed, Science Direct, SCOPUS, and Psychinfo.

Intervention(s)

None.

Main Outcome Measure(s)

Papers discussing transgender men, fertility preservation (FP), and FP counseling.

Result(s)

The primary search yielded 1,067 publications. After assessing eligibility and evaluating with a quality assessment tool, 25 articles remained, including 8 reviews, 5 surveys, 4 consensus studies, 3 retrospective studies, 3 committee opinions, and 2 guidelines. Publications highlighted the importance of including the following topics during counseling: (1) FP and family building options; (2) FP outcomes; (3) effects of testosterone therapy on fertility; (4) contraception counseling; (5) attitudes toward family building; (6) consequences of transgender parenting; and (7) barriers to success.

Conclusion(s)

Currently, there is a lack of standardization for comprehensive counseling about FP for transgender men. Standardized approaches can facilitate conversation between physicians and transgender men and ensure patients are making informed decisions regarding pelvic surgery and future family building plans.

Access to fertility preservation for trans and non-binary people in Aotearoa New Zealand

There is a growing need for healthcare professionals to discuss fertility preservation options with trans and non-binary people before commencing medical transition as part of informed consent-based models of care. In this article, we adapt the Five-A framework of healthcare access to examine fertility preservation information and services. To do so, we present an analysis of data from Counting Ourselves, the first comprehensive national survey in Aotearoa New Zealand of trans and non-binary people's health and the first study exploring their access to cryopreservation information and services. Among 419 participants who had received gender-affirming hormones or surgery, 33.7% received information about options for fertility preservation and 15.8% accessed fertility preservation services. Findings from the study indicate the need for greater understanding of trans and non-binary people's desire for genetically related children, and what type of information and form of delivery would be most helpful to ensure equitable outcomes in relation to decision-making around fertility and future family-building.

Puberty Suppression in Transgender and Gender-Diverse Adolescents: Timely Care for Optimal Outcomes

In this perspective, we argue that pubertal suppression with gonadotropin-releasing hormone analogues is a safe reversible intervention that should be made available to transgender and gender-diverse youth starting at early puberty. Recent data suggest puberty suppression is generally initiated among individuals once puberty has significantly progressed, thus reducing the effectiveness of the intervention. Delays and barriers to such care may systematically introduce permanent avoidable disadvantages for this vulnerable and marginalized group.

Fertility preservation in transgender and non-binary adolescents and young adults

Although 37.5–51% of transgender adults state they would’ve considered freezing gametes before gender-affirming therapy if offered and 24–25.8% of transgender adolescents express interest in having biological children, less than 5% of transgender adolescents have opted for fertility preservation. We sought to assess fertility preservation utilization in our multidisciplinary adolescent gender clinic. We also aimed to identify fertility preservation utilization and interest among non-binary adolescents and young adults. A retrospective review was conducted of patients seen in the Stanford Pediatric & Adolescent Gender Clinic from October 2015 through March 2019 who were >10 years of age at initial visit. All individuals with documented discussion of fertility preservation were offered referral for formal fertility preservation consultation but only 24% of patients accepted. Only 6.8% of individuals subsequently underwent fertility preservation (n = 9). Transfeminine adolescents are more likely to pursue fertility preservation than transmasculine adolescents (p = 0.01). The rate of fertility preservation in non-binary adolescents did not significantly differ from those in transfeminine adolescents (p = 1.00) or transmasculine adolescents (p = 0.31). Although only one non-binary individual underwent fertility preservation, several more expressed interest with 36% accepting referral (n = 4) and 27% being seen in consultation (n = 3). Despite offering fertility preservation with designated members of a gender clinic team, utilization remains low in transgender adolescents. Additionally, non-binary adolescents and their families are interested in fertility preservation and referrals should be offered to these individuals. Further studies and advocacy are required to continue to address fertility needs of transgender adolescents.

Fertility preservation and fertility treatment in transgender adolescents and adults in a Swedish region, 2013-2018

STUDY QUESTION

In a transgender population referred for fertility consultation, which factors influence the decision to cryopreserve oocytes and sperm?

SUMMARY ANSWER

Previous hormonal treatment, gender affirmation surgery and sexual orientation were associated with the decision to undergo fertility preservation and transgender women underwent fertility preservation more frequently than transgender men.

WHAT IS KNOWN ALREADY

It is well-known internationally that fertility preservation and fertility treatment are increasingly requested by transgender men and women. Factors affecting their decisions as well as treatment differences between transgender women and transgender men have been reported, but many studies have had low participation rates and small sample sizes.

STUDY DESIGN, SIZE, DURATION

This retrospective cohort study, conducted during 2013–2018, included 78 transgender women (assigned male at birth and referred for sperm cryopreservation) and 164 transgender men (assigned female at birth referred for oocyte cryopreservation).

PARTICIPANTS/MATERIALS, SETTING, METHODS

In 2013, the previous requirement for sterilization before completion of a legal gender change was removed in Sweden. All fertile-aged transgender men and transgender women referred to a tertiary care centre for consultation concerning fertility preservation, fertility treatment or hysterectomy were identified from administrative systems. Demographic, medical and treatment data were extracted from electronic medical records and from an ART database. Logistic regression was applied to analyse factors affecting the decision to cryopreserve gametes among transgender men and transgender women.

MAIN RESULTS AND THE ROLE OF CHANCE

A majority of transgender men (69.5%) and transgender women (82%), wanted to become parents. Fertility preservation was less frequent in transgender men than in transgender women (26.2% versus 75.6%, respectively). No individuals among those primarily referred for hysterectomy opted for cryopreservation of oocytes. Among transgender men, young age, no previous hormonal treatment and stating homosexual orientation were independent factors associated with the decision to cryopreserve oocytes. Among transgender women, the decision to undergo gender affirmation surgery and stating heterosexual orientation were independent factors associated with a decision to refrain from fertility preservation. Fertility treatments, using IUI or IVF with donor sperm, were mainly performed in partners of transgender men. Ten live births were reported in the group of transgender men and two for transgender women.

LIMITATIONS, REASONS FOR CAUTION

The main limitation is the retrospective nature of the study, with missing data for many variables. The short study period and the study population being too young to permit observation of long-term outcomes of fertility preservation and fertility treatments are reasons for caution.

WIDER IMPLICATIONS OF THE FINDINGS

Our results confirm that fertility preservation has been requested by transgender people since the change in Swedish legislation in 2013. Information about aspects of fertility early in the transition process is important, since hormonal and surgical treatments may have a large impact on the decision to undergo fertility preservation. It is important to train fertility clinic staff to identify and handle the specific obstacles, as well as address the need for information and support that transgender people may have when planning for fertility preservation, fertility treatment and pregnancy.

STUDY FUNDING/COMPETING INTEREST(S)

This research was supported by a grant from the Swedish state, under the ALF agreement between the Swedish government and the county councils (ALFGBG-720291), and by Hjalmar Svensson’s Research Foundation. None of the authors has any conflict of interest to declare.

Approach to the Patient: Pharmacological Management of Trans and Gender-Diverse Adolescents

Internationally, increasing numbers of children and adolescents with gender dysphoria are presenting for care. In response, gender-affirming therapeutic interventions that seek to align bodily characteristics with an individual's gender identity are more commonly being used. Depending on a young person's circumstances and goals, hormonal interventions may aim to achieve full pubertal suppression, modulation of endogenous pubertal sex hormone effects, and/or development of secondary sex characteristics congruent with their affirmed gender. This is a relatively novel therapeutic area and, although short-term outcomes are encouraging, longer term data from prospective longitudinal adolescent cohorts are still lacking, which may create clinical and ethical decision-making challenges. Here, we review current treatment options, reported outcomes, and clinical challenges in the pharmacological management of trans and gender-diverse adolescents.

Transgender Medicine and Hormone Therapy: What the Gynecologist Needs to Know

The transgender community comprises individuals with diverse identities in both gender and sexual orientation. Unfortunately, many face discrimination and harassment within our society-including within the medical system. There is an overall lack of provider training in transgender specific health which has led to health disparities and inequities within this population. This chapter aims to elucidate the medical needs unique to transgender and gender nonconforming individuals and thus enable medical providers to meet those needs with competency and compassion.

Predicting successful sperm retrieval in transfeminine adolescents after testicular biopsy

PURPOSE

Increasing numbers of transgender adolescents are receiving gender-affirming treatments (GAT). Given GAT can impair reproductive function, clinical guidelines advise prior counselling regarding fertility preservation (FP). For transgender adults assigned male at birth, FP is usually achieved via a masturbatory sample and sperm cryopreservation. This is less straightforward in transgender adolescents, since they may not be developmentally ready to masturbate and/or masturbation may cause unacceptable gender dysphoria. Testicular biopsy represents an alternative method for sperm retrieval in these adolescents, but for those in early/mid puberty, it is difficult to predict whether sperm will be found. The purpose of this study was therefore to identify factors that predict successful sperm retrieval for cryopreservation via testicular biopsy.

METHODS

A retrospective cohort study was undertaken at a tertiary-referral pediatric gender service. Subjects were included if they'd received a testicular biopsy in association with the commencement of GAT between 2010 and 2019. The primary outcome measure was successful sperm retrieval, and potential predictors included age, testicular volume and serum testosterone, LH and FSH levels.

RESULTS

Of 25 subjects who received a biopsy prior to starting any GAT, 17 had successful sperm retrieval. While age, testosterone, LH and FSH levels showed minimal differences, testicular volume was significantly higher in those with successful sperm retrieval, and a threshold of ≥ 10 mL showed 92% sensitivity and 71% specificity in predicting successful retrieval. An additional 6 patients received a biopsy after starting puberty suppression and before commencement of oestrogen, and one of these individuals had sperm successfully retrieved despite > 2 years of regular puberty suppression.

CONCLUSION

These findings suggest that testicular volume is most useful in predicting successful sperm retrieval following testicular biopsy in transgender adolescents and are likely to be of relevance to other young people undertaking FP, including those with cancer.

Challenges in the care of transgender and gender-diverse youth: an endocrinologist's view

An increasing number of transgender and gender-diverse (TGD) youth (early pubertal through to late adolescent, typically 9-10 through to 18 years of age) are seeking medical services to bring their physical sex characteristics into alignment with their gender identity - their inner sense of self as male or female or somewhere on the gender spectrum. Compelling research has demonstrated the clear mental health - even life-saving - benefits of gender-affirming care, but current clinical practice guidelines and standards of care are based on only several short-term and a few medium-term outcomes studies complemented by expert opinion. Nevertheless, although the relative paucity of outcomes data raises concerns, the stance of not intervening until more is known is not a neutral option, and large observational studies evaluating current models of care are necessary and are now underway. This Review highlights key advances in our understanding of transgender and gender-diverse youth, the challenges of providing gender-affirming care, gaps in knowledge and priorities for research.

Gender Diverse Youth on Fertility and Future Family: A Qualitative Analysis

PURPOSE

Gender-affirming treatment for transgender and nonbinary adolescents has been shown to decrease anxiety, depression, and suicidality, but treatments have medical consequences. Specifically, hormone replacement and pubertal blocking may impact patients' fertility and childbearing capabilities. We interviewed gender diverse adolescents regarding their thoughts on family and fertility.

METHODS

We completed semistructured interviews with 23 gender diverse adolescents recruited from the Seattle Children's Gender Clinic. Interviewees included transfeminine, transmasculine, and nonbinary youth. Interviews were recorded, transcribed, and analyzed using Braun and Clarke's theory of thematic analysis, a flexible framework for qualitative analysis.

RESULTS

Gender diverse adolescents have myriad views on fertility, but four main themes were identified: (1) an interest in future family, including ideas regarding adoption and biological children; (2) barriers to fertility, including cost and procedure-related dysphoria; (3) factors unique to the developmental stage of adolescents, including the age discordance of making fertility decisions as a teenager and parental influence on decision-making; and (4) suggestions for clinicians approaching fertility counseling with adolescents considering hormone therapy.

CONCLUSIONS

Many gender diverse youth asserted an interest in building families, although the process of fertility preservation remains fraught. Relative to other studies, our participants were hopeful, imaginative, and interested in having children. Participants wanted to receive specific counseling on fertility, to receive help navigating the logistics of fertility preservation, and to be listened to when their hopes for children (or no children) were stated. Further research is needed to create care paradigms that address fertility of transgender youth in an affirming, developmentally appropriate manner.

Effective fertility counselling for transgender adolescents: a qualitative study of clinician attitudes and practices

OBJECTIVE

Fertility counselling for trans and gender diverse (TGD) adolescents has many complexities, but there is currently little guidance for clinicians working in this area. This study aimed to identify effective strategies for-and qualities of-fertility counselling for TGD adolescents based on clinicians' experiences.

DESIGN

We conducted qualitative semi-structured individual interviews in 2019 which explored clinician experiences and fertility counselling practices, perspectives of the young person's experience and barriers and facilitators to fertility preservation access. Data were analysed using thematic analysis.

SETTING

This qualitative study examined experiences of clinicians at the Royal Children's Hospital-a tertiary, hospital-based, referral centre and the main provider of paediatric TGD healthcare in Victoria, Australia.

PARTICIPANTS

We interviewed 12 clinicians from a range of disciplines (paediatrics, psychology, psychiatry and gynaecology), all of whom were involved with fertility counselling for TGD adolescents.

RESULTS

Based on clinician experiences, we identified five elements that can contribute to an effective approach for fertility counselling for TGD adolescents: a multidisciplinary team approach; shared decision-making between adolescents, their parents and clinicians; specific efforts to facilitate patient engagement; flexible personalised care; and reflective practice.

CONCLUSIONS

Identification of these different elements can inform and hopefully improve future fertility counselling practices for TGD adolescents, but further studies examining TGD adolescents' experiences of fertility counselling are also required.

Fertility Options for the Transgender and Gender Nonbinary Patient

Comprehensive care for transgender and gender nonbinary patients has been a priority established by the World Professional Association for Transgender Health. Because pubertal suppression, gender-affirming hormone therapy, and antiandrogen therapy used alone or in combination during medical transition can affect gonadal function, understanding the effects these treatments have on fertility potential is important for practitioners caring for transgender and gender nonbinary patients. In this review, we outline the impacts of gender-affirming treatments on fertility potential and discuss the counseling and the treatment approach for fertility preservation and/or family building in transgender and gender nonbinary individuals.

Formative development of a fertility decision aid for transgender adolescents and young adults: a multidisciplinary Delphi consensus study

PURPOSE

No educational and decision support tools exist to aid transgender and non-binary (TNB) adolescents and young adults (AYA) in making decisions about fertility preservation in the context of initiating gender-affirming medical care that can impair fertility. This study identified critical content areas and learning objectives to include in a decision aid about fertility preservation targeted for TNB AYA.

METHODS

Delphi methodology was leveraged to engage 80 multidisciplinary experts in reproductive medicine and pediatric transgender health care in a two round consensus building procedure. Proposed content areas rated as "probably keep" or "definitely keep" by 75% of experts were retained. Proposed learning objectives reaching 75% agreement on ratings of importance and priority were also identified.

RESULTS

The Delphi procedure identified five priority content areas (Basic Reproduction; Gender-Affirming Medical Interventions: Impacts on Fertility; Established Fertility Preservation Options; Benefits and Risks of Established Fertility Preservation Procedures; Alternative Pathways to Parenting) and 25 learning objectives to prioritize in a fertility-related decision aid for TNB AYA.

CONCLUSION

A multidisciplinary panel of experts achieved agreement around content areas and learning objectives to incorporate into a decision aid about fertility preservation for TNB AYA.

Ovarian stimulation outcomes among transgender men compared with fertile cisgender women

PURPOSE

To compare assisted reproductive technology (ART) outcomes among transgender men with those of fertile cisgender women.

METHODS

This retrospective cohort study included 12 transgender men, six with no testosterone exposure and six after testosterone treatment, and 12 cisgender women (oocyte donors) who underwent ART in our institution between June 2017 and December 2019. Statistical analyses compared ART data and outcomes between three groups: cisgender women, transgender men without testosterone exposure, and transgender men after testosterone exposure. Comparisons were also made between transgender men with and without testosterone exposure.

RESULTS

The transgender men with no testosterone exposure (23.3 ± 4 years) were significantly younger than the transgender men who had undergone testosterone treatment (30.3 ± 3.8 years; P = 0.012) and the cisgender women (29.1 ± 3.1 years; P = 0.004). The amount of FSH used for ovulation induction (1999 ± 683 mIU/mL) was significantly lower among transgender men without prior testosterone exposure compared with that among cisgender women (3150 ± 487 mIU/mL; P = 0.007). There were no differences in the peak estradiol levels, the number of oocytes retrieved, the number of MII oocytes, and the oocyte maturity rates between the three groups. Five out of six testosterone-treated transgender men underwent embryo cryopreservation, and they all achieved good-quality embryos.

CONCLUSIONS

Transgender men have an excellent response to ovulation stimulation even after long-term exposure to testosterone. Oocyte/embryo cryopreservation is, therefore, a feasible and effective way for them to preserve their fertility for future biological parenting.
