Transgenderism and reproduction

Understanding the Strengths and Limitations of Online Oocyte Cryopreservation Calculators

Between 2010 and 2016, elective oocyte cryopreservation (OC) increased in use by 880% in the United States; however, there have been increasing reports of regret among patients after elective OC. There is a growing need for individualized counseling on the timing and number of oocytes to cryopreserve for patients to make informed choices and set realistic expectations, but currently available tools seem to be insufficient. The purpose of this review is to describe the OC calculators currently available online, identify sources of regret, and illustrate the need for unified counseling tools for improved patient care and education. OC calculators were identified via Google search. Only calculators that cite scientific literature were included in the review. Calculators for in vitro fertilization or embryo transfer were excluded. Thirteen OC calculators were found; however, only six cited literature supporting the calculator's design. When entering the same hypothetical patient parameters for age and number of oocytes cryopreserved, the calculators provided drastically different probabilities of live births. The lack of cohesive online educational materials creates confusion and stress for patients considering OC, leading to unrealistic expectations and increased feelings of regret thereafter. Physicians need tools to provide comprehensive guidance to patients seeking to cryopreserve oocytes.

Parenting intentions in transgender and gender-nonconforming adults

OBJECTIVE

To assess parenting intentions, knowledge and attitudes regarding fertility preservation, and barriers to achieving parenthood in an adult transgender population.

METHODS

This was a multi-center online cross-sectional study conducted at three university-affiliated and 15 community-affiliated clinics within a major US city. Inclusion criteria included being aged 18 years and older and self-identification as transgender, gender non-conforming or non-binary. Eighty respondents completed a 36-question survey regarding their transition and plans to achieve parenthood. We compared demographic characteristics to plan for transition using Chi-Square analysis. We compared options to achieve parenthood to plans for transition using ANOVA, Spearman's rho correlation coefficient, and a Kruskal Wallis H test.

RESULTS

The mean desire to become a parent was 59.9 on a scale of 1-100. There was no significant association between plan for gonadectomy and reduced preference for the use of autologous gametes for parenting [H(2) = 1.309, P = 0.520]. The desire to have children was correlated with an increasing willingness to pause cross-sex hormones (r_s  = 0.40, P < 0.01). Cost was identified as the largest barrier to fertility preservation (54.1%).

CONCLUSION

The majority of transgender adults surveyed desire parenthood and this could be correlated with plan for transition including willingness to suspend cross-sex hormones.

Fertility Desire and Motivation Among Individuals with Gender Dysphoria: A Comparative Study

Despite receiving Gender-Affirming Hormone Therapy or Gender-Affirming Surgery, which may adversely impact their fertility, people with Gender Dysphoria (GD) may desire to form families. In this study, we aimed to quantitatively display fertility desire from the perspective of these individuals, despite all the legal challenges they face. The single center, cross-sectional comparative study included individuals with GD and cisgender volunteers. A Sociodemographic Data Form, the Fertility Desire Data Form, the Childbearing Motivations Scale and the Fertility Desire Scale were used. Of the 414 participants, 171 were individuals with GD (110 FtM; 61 MtF) and 243 were cisgender volunteers (142 cis-males; 101 cis-females). While 22% of the people with GD stated that they had regrets about not undergoing fertility preservation, 16% stated that they would like this process if it were legal. People with GD, particularly MtF, want to have children more than cisgenders. Moreover, people with MtF exhibited less negative motivations toward becoming parents, despite having reservations regarding the socioeconomic aspect of parenthood. Our findings indicate that fertility desire in people with GD is not less in comparison to cisgender people. Healthcare professionals should not forget to offer fertility preservation options as part of clinical practice before Gender-Affirming Therapy.

SIGIS-SIAMS-SIE position statement of gender affirming hormonal treatment in transgender and non-binary people

PURPOSE

Gender Incongruence (GI) is a marked and persistent incongruence between an individual's experienced and the assigned gender at birth. In the recent years, there has been a considerable evolution and change in attitude as regards to gender nonconforming people.

METHODS

According to the Italian Society of Gender, Identity and Health (SIGIS), the Italian Society of Andrology and Sexual Medicine (SIAMS) and the Italian Society of Endocrinology (SIE) rules, a team of experts on the topic has been nominated by a SIGIS-SIAMS-SIE Guideline Board on the basis of their recognized clinical and research expertise in the field, and coordinated by a senior author, has prepared this Position statement. Later on, the present manuscript has been submitted to the Journal of Endocrinological Investigation for the normal process of international peer reviewing after a first internal revision process made by the SIGIS-SIAMS-SIE Guideline Board.

RESULTS

In the present document by the SIGIS-SIAMS-SIE group, we propose experts opinions concerning the psychological functioning, gender affirming hormonal treatment, safety concerns, emerging issues in transgender healthcare (sexual health, fertility issues, elderly trans people), and an Italian law overview aimed to improve gender non-conforming people care.

CONCLUSION

In this Position statement, we propose experts opinions concerning the psychological functioning of transgender people, the gender-affirming hormonal treatment (full/partial masculinization in assigned female at birth trans people, full/partial feminization and de-masculinization in assigned male at birth trans people), the emerging issues in transgender health care aimed to improve patient care. We have also included an overview of Italian law about gender affirming surgery and registry rectification.

Non-binary reproduction: Stories of conception, pregnancy, and birth

Background: Many non-binary individuals AFAB (assigned female at birth) seek gestational parenthood. However, the limited available literature is often focused on trans men and overlooks the conception, pregnancy, and birth experiences of non-binary parents. Aims: The study aimed to capture the unique reproduction narratives of non-binary people AFAB. Methods: Five non-binary individuals volunteered to participate in this study. Data were collected using largely unstructured, in-depth, tape-recorded interviews. Thematic analysis of the verbatim transcripts and tape recordings yielded a chronological, cohesive narrative for each participant. Four participants reviewed their narrative and confirmed that their story was accurately represented. The individual narratives were then woven into one collective narrative, and common themes across the participants' stories were identified. Results: Before conception, most participants considered how to balance their medical and social transitions with their reproductive goals. Conception was relatively easy and straightforward for the four participants who used their partner's sperm. The gendered nature of, and language surrounding, pregnancy greatly impacted participant's reproductive experiences, leading to feelings of isolation and loneliness, difficulties finding maternity clothes and gender dysphoria. Participants desired gender-affirming care and reported mostly positive experiences with their healthcare providers. Their gender identity influenced their experiences of parenthood, as well as the decisions they made regarding the disclosure of their gender identity to others, their gender presentation, chestfeeding, and parental designations. Discussion: The cisnormative and heteronormative scripts that surround pregnancy shaped the reproductive narratives of those who participated in this research. The findings reinforce the importance of inclusive, gender-affirming healthcare and social support services.

Functional ovarian reserve in transgender men receiving testosterone therapy: evidence for preserved anti-Müllerian hormone and antral follicle count under prolonged treatment

STUDY QUESTION

Is the functional ovarian reserve in transgender men affected by testosterone therapy?

SUMMARY ANSWER

Serum anti-Müllerian Hormone (AMH) levels slightly decrease during testosterone treatment but remain within the normal range, suggesting preserved follicular ovarian reserve.

WHAT IS KNOWN ALREADY

Few small studies have investigated the impact of gender-affirming treatment on reproduction in transgender men. Conflicting results were reached concerning ovarian morphology and AMH levels in this context.

STUDY DESIGN, SIZE, DURATION

The study consisted of two arms. The first arm was a prospective pilot study, which enrolled 56 transgender men (median age 22.5 [interquartile range (IQR)-19-27.7] years), 27 of whom had polycystic ovary syndrome (PCOS), prior to the initiation of gender-affirming testosterone therapy. A structured assessment was conducted prior to, and at 3 and 12 months after treatment initiation. The second arm was a cross-sectional study that comprised 47 transgender men (median age 24 [IQR-20-31] years) who received testosterone for a median duration of 35 [IQR 13-62] months. The main outcome measures were serum AMH and antral follicle count (AFC) as indices of ovarian follicular reserve.

PARTICIPANTS/MATERIALS, SETTING, METHODS

The study was conducted at a tertiary center for transgender health. Gender-affirming therapy was administered according to standard practice. AFC was determined by pelvic (abdominal or transvaginal) ultrasound and blood collection for measurements of AMH, testosterone, estradiol, LH and FSH was performed at the designated time-points.

MAIN RESULTS AND THE ROLE OF CHANCE

Prospective arm for the entire group we observed a decrease of 0.71 ng/ml in AMH levels between baseline and 12 months (P = 0.01). When expressed in age-specific percentiles, AMH went from the 47.37th to the 40.25th percentile at 12 months (P < 0.001). In a sub-group analysis, a decline of 9.52 points in age-specific percentile was seen in subjects with PCOS (P < 0.001), while no changes were detected in the non-PCOS group. Testosterone treatment did not affect AFC over time in the entire cohort. In the sub-group analysis, a mean decrease of 5.0 follicles was detected between baseline and the 12 months assessment (P = 0.047) only in subjects with PCOS. In the cross-sectional study, AMH inversely correlated with age but not with treatment duration. Notably AMH did not deviate from the 50th age-specific percentile. Finally, four men fathered biological children after being under testosterone treatment for up to 12 years.

LIMITATIONS, REASONS FOR CAUTION

The limited sample size of the pilot study should be kept in mind. An additional limitation is the lack of a control group in the prospective study, as each participant served as his own control. Also, roughly 40% of the ultrasound examinations were performed transabdominally, potentially affecting the accuracy of the AFC measurements.As study participants were quite young, our reassuring data may not apply to older transgender men, either because of an age-related decline in ovarian reserve or to possible long-term effects of testosterone therapy. Furthermore, the chances for fertility preservation may be more limited in subjects with PCOS.

WIDER IMPLICATIONS OF THE FINDINGS

This is an additional contribution to the emerging evidence that prolonged testosterone treatment may not be a major obstacle to later fertility potential in transgender men desirous of having children. Larger confirmatory studies, and particularly more with reproductive outcome data, are needed for evidence-based fertility counseling prior to treatment initiation in these subjects.

Serum and intratesticular inhibin B, AMH, and spermatogonial numbers in trans women at gender-confirming surgery: An observational study

BACKGROUND

Anti-Müllerian hormone and inhibin B are produced by Sertoli cells. Anti-Müllerian hormone secretion indicates an immature Sertoli cell state. Inhibin B serves as a marker of male fertility. Identification of markers reflecting the presence of germ cells is of particular relevance in trans persons undergoing gender-affirming hormone therapy in order to offer individualized fertility preservation methods.

OBJECTIVES

Serum and intratesticular inhibin B and anti-Müllerian hormone values were assessed and related to clinical features, laboratory values, and germ cell numbers.

MATERIALS AND METHODS

Twenty-two trans women from three clinics were included. As gender-affirming hormone therapy, 10-12.5 mg of cyproterone acetate plus estrogens were administered. Height, weight, age, medication, and treatment duration were inquired by questionnaires. Serum luteinizing hormone, follicle-stimulating hormone, testosterone, and estradiol were measured by immuno-assays. Serum and intratesticular inhibin B and anti-Müllerian hormone were measured by commercially available ELISAs. Spermatogonia were quantified as spermatogonia per cubic millimeter testicular tissue applying a morphometric analysis of two independent testicular cross-sections per individual after MAGEA4 immunostaining.

RESULTS

Patients with high inhibin B levels presented with a higher number of spermatogonia (*p < 0.05). Furthermore, mean serum inhibin B was associated with low age (*p < 0.05), low follicle-stimulating hormone (*p < 0.05), and low testosterone (*p < 0.05). Serum anti-Müllerian hormone, however, was not related to spermatogonial numbers. It correlated with high testosterone (*p < 0.05) and high follicle-stimulating hormone (*p < 0.05) only. High intratesticular inhibin B was accompanied by high luteinizing hormone (*p < 0.05), high follicle-stimulating hormone (**p < 0.01), and high testosterone levels (**p < 0.01). Higher the intratesticular anti-Müllerian hormone levels, the longer gender-affirming hormone therapy was administered (*p < 0.05).

DISCUSSION AND CONCLUSION

Serum inhibin B levels indicate the presence of spermatogonia, whereas anti-Müllerian hormone seems not to be a reliable marker concerning germ cell abundance.

Low feasibility of in vitro matured oocytes originating from cumulus complexes found during ovarian tissue preparation at the moment of gender confirmation surgery and during testosterone treatment for fertility preservation in transgender men

OBJECTIVE

To study the feasibility of in vitro maturation of ovarian tissue oocytes for fertility preservation in transgender men on testosterone treatment.

DESIGN

Cross-sectional study SETTING: University hospital PATIENT(S): Eighty-three transgender men enrolled from November 2015 to January 2019 INTERVENTION(S): In vitro maturation of cumulus-oocyte complexes (COCs) harvested at the time of gender confirmation surgery, and fertilization through intracytoplasmic sperm injection.

MAIN OUTCOME MEASURE(S)

In vitro maturation, fertilization, and blastulation rates; comparison of morphokinetics with vitrified-warmed oocytes; and analysis of the genetic profiles of embryos.

SECONDARY OUTCOMES

association between serum hormone levels; COCs' morphologic characteristics, and vitrification rate.

RESULT(S)

All participants were on testosterone treatment for a median of 83 (64[Quartile 1]; 113.2[Quartile 2]) weeks. A total of 1,903 COCs (mean per participant, 23 ± 15.8) were collected. The in vitro maturation rate was 23.8%, vitrification rate was 21.5%, and survival rate after warming was 72.6% (n = 151). Intracytoplasmic sperm injection was performed in 139 oocytes. The rate of normal fertilized oocytes was 34.5%, and 25 (52.1%) embryos reached day 3. One blastocyst was achieved on day 5. Aberrant cleavage patterns and early embryo arrest were observed in 22 (45.8%) and 44 (91.7%) zygotes, respectively. Compared with vitrified-warmed donor oocytes, a delay was observed in pronuclei disappearance, t2 (time to reach 2 cell stage) timings, and CC1 (the duration of the 1st cell cycle) and SS3 (synchronization of cleavage pattern (calculated as t8-t5) time intervals. A normal genetic pattern was seen in 42% embryos. The proportion of vitrified oocytes was negatively associated with progesterone (odds ratio, 0.76) and positively associated with antimüllerian hormone serum levels (odds ratio, 1.23). The highest vitrification rate was achieved by the morphologic characteristic 344 at day 0 and by 433 at day 2.

CONCLUSION(S)

Ovarian tissue oocytes matured in vitro show low developmental capacity in transgender men, when collected under testosterone treatment.

Endocrine Management of Transgender Adults: A Clinical Approach

The attention to transgender medicine has changed over the last decade and the interest is most likely going to increase in the future due to the fact that gender-affirming treatments are now being requested by an increasing number of transgender people. Even if gender-affirming hormone therapy (GAHT) is based on a multidisciplinary approach, this review is going to focus on the procedures adopted by the endocrinologist in an out-clinic setting once an adult patient is referred by another specialist for ‘gender affirming’ therapy. Before commencing this latter treatment, several background information on unmet needs regarding medical and surgical outcomes should be investigated. We summarized our endocrinological clinical and therapeutic approaches to adult transgender individuals before and during GAHT based on a non-systematic review. Moreover, the possible relationships between GAHT, gender-related pharmacology, and COVID-19 are also reported.

Pediatric Research and Health Care for Transgender and Gender Diverse Adolescents and Young Adults: Improving (Biopsychosocial) Health Outcomes

Adolescent and young adult (AYA) transgender health care and research have expanded rapidly in the United States and abroad, but the effects of gender-affirming social, hormonal, or surgical care on overall health remain unclear. Gender diverse identities, also termed nonbinary, have often been neglected in favor of (male/female) binary identities, even in the context of transgender health care and research. No high quality studies have assessed how gender-affirming medical care impact health inequities in transgender and gender diverse (TG/GD) adults, much less in AYAs, despite the fact that that TG/GD adults have higher than average morbidity and mortality across a host of health concerns, from human immunodeficiency virus infection to thromboembolism, and that reported depression with suicidal ideation is >10 times higher in TG/GD adults than in the general population. TG/GD youth have related but different needs from TG/GD adults. TG/GD AYA are embedded in family and schools, where stigma may be difficult to escape; mental health during adolescence has areas of increased risk as well as resilience; and the effects of early hormonal and surgical interventions on long-term health are insufficiently studied. Because of this, an inclusive and proactive approach to addressing the needs of TG/GD AYA by pediatric clinicians, researchers, and educators is particularly crucial. This article focuses on what is known and unknown about clinical practice, research, and education related to TG/GD health. We highlight the role of gender affirmation by clinicians as they care and advocate for TG/GD AYAs; the potential challenges of hormonal treatment for peripubertal youth; and short- and long-term effects on physical and reproductive health of medical or surgical interventions. We also discuss how social context influences knowledge gaps and the health-relevant risks faced by TG/GD AYA. The challenges are formidable, but opportunities await: high priority research questions to explore, educational gaps to be filled, and advocacy that needs the voices of pediatricians to promote policies to facilitate positive health outcomes for TG/GD AYA.

A transgender man, a cisgender woman, and assisted reproductive technologies: a Brazilian case report

Transgender men are individuals who identify as men but were assigned female at birth. Gender-affirming medications include testosterone hormone therapy, known for its diverse effects throughout the body, which include endometrial atrophy and the induction of amenorrhea by suppressing ovulation, without however affecting the ovarian follicle pool. This paper reports the first case in Brazil involving a transgender man and a cisgender woman attempting to form a family. A 34-year-old transgender man and a 28-year-old woman came to our assisted reproduction service. He had been on testosterone for two years. At their initial consultation, testosterone therapy was discontinued. Controlled ovarian stimulation for the transgender man was achieved using a combination of recombinant gonadotropins FSH and LH. Pituitary blockage was performed using a GnRH antagonist protocol. Twenty follicles were aspirated and 16 oocytes were retrieved, 12 of which mature. They were inseminated with donor semen. On the fifth day of development, one high quality blastocyst was transferred to the cisgender woman, resulting in an ongoing pregnancy. Five supernumerary embryos were cryopreserved. Controlled ovarian stimulation with high quality oocytes, high quality embryos, and clinical pregnancy are possible for transgender men, even with a history of testosterone use.

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.

Markers of vitality in ovaries of transmen after long-term androgen treatment: a prospective cohort study

BACKGROUND

Gender-affirming hormone therapy has been hypothesized to reduce the patient's reproductive potential in transmen, although the exact long-term effects on future fertility are unknown.

METHODS

In this prospective cohort study we aimed to evaluate ovaries of 20 transmen by using hormone serum levels, histomorphological analysis and fluorescence activated cells sorting (FACS) analysis - in order to assess the amount of vital cells.

RESULTS

The median total number of follicles per field of view was 39 (IQR 12-122). Of all follicles (n = 1661), the vast majority was primordial (n = 1505, 90.6%), followed by primary (n = 76, 4.6%), abnormal (n = 63, 3.8%) and secondary follicles (n = 17, 1.0%). FACS analysis was available for 13 samples (65.0%) and the median frequency of vital cells was 87.5% (IQR, 77.7-95.4%). Both a higher age (p = 0.032) and a lower BMI (p = 0.003) were significantly associated with a higher frequency of vital cells.

CONCLUSION

The majority of ovarian cells after long-term androgen treatment were vital in FACS analysis and histomorphological evaluation revealed a normal cortical follicle distribution. These results are currently exploratory, but might be promising for issues on fertility preservation.

TRIAL REGISTRATION

The study was approved by the ethics committee of the Medical University of Vienna (EK 2240/2016) and was retrospectively registered in the Current Controlled Trials Register (registration number NCT03649087 , date of registration: 28.08.2018).

Ethical issues involving fertility preservation for transgender youth

PURPOSE

To investigate ethical issues associated with fertility preservation (FP) in transgender youth based on reports of patients and their parents.

METHODS

Our qualitative study involved in-person interviews with 54 subjects (35 patients and 19 parents). Interviews were audio recorded, transcribed, and verified. Each subject completed a demographic questionnaire, and each patient's medical chart was reviewed for additional information. We analyzed the data using inductive thematic content analysis.

RESULTS

Themes that emerged included a range of desires and ambivalence about having genetically related children, variability in understanding the potentially irreversible impact of gender affirming hormones (GAHs) on fertility, use of adoption, and the impact of age on decision-making. Subjects (patients and parents) noted barriers to FP, such as cost and insurance coverage. Several parents expressed concern that their transgender children may have future regret about not attempting FP. Both transgender youth and their parents felt FP was an important precaution.

CONCLUSIONS

Our study took advantage of the richness of personal narratives to identify ongoing ethical issues associated with fertility preservation in transgender youth. Transgender youth and their parents did not fully understand the process of FP, especially regarding the effects of GAHs, had fears that FP could reactivate gender dysphoria, and noted barriers to FP, such as cost, highlighting economic disparity and lack of justice. These findings highlight ethical issues involving the adequacy of informed consent and economic injustice in access to FP despite expressed interest in the topic.

Fertility Counseling for Transgender Adolescents: A Review

International guidelines in transgender health recommend fertility counseling before the commencement of puberty suppression, estrogen, or testosterone, given the potential for these treatments to impair fertility. However, these recommendations provide little actual guidance to clinicians. Consequently, differences in knowledge and attitudes may lead to clinicians adopting different approaches and goals in the fertility counseling they provide. This review draws attention to the disparity between the rates of desire for genetic parenthood among transgender individuals and the actual rates of fertility preservation (FP) and examines different factors in fertility counseling that affect clinical practice and contribute to this disparity. These factors include how a lack of strong evidence-for the effects of hormone therapy on future fertility and success rates of some FP options-impacts upon counseling, transgender peoples' experiences of fertility counseling and preservation, consideration of a young person's developmental stage and the roles of parents and clinicians in the decision-making process, considerations shaping transgender adolescents' decisions to preserve fertility, and access barriers to FP. In doing so, this review highlights the complexities and issues that clinicians must consider when providing fertility counseling to transgender adolescents and-in part-helps to address the lack of detailed clinical guidelines in this area.

Attitudes and experiences of health care professionals when caring for transgender men undergoing fertility preservation by egg freezing: a qualitative study

Background:

As gender-affirming treatment may have a negative impact on fertility, reproductive health counseling to patients seeking medical or surgical gender-affirming treatment should be provided, including the option to undergo fertility preservation (FP). Experiences of transgender men undergoing FP treatments aimed at oocyte freezing have reported a negative impact of the treatments on gender dysphoria. No previous studies have investigated the experiences of health care professionals’ (HCP) when caring for transgender men undergoing such treatments.

Aim:

The aim of this study was to investigate HCP’s attitudes and experiences when meeting transgender men undergoing FP through oocyte freezing.

Methods:

Individual interviews were conducted in 2016 with 13 HCPs working at a Reproductive Medicine clinic in Sweden. Data were analyzed by thematic content analysis.

Results:

The main theme found, How to maintain professionalism, showed that HCPs experienced important challenges to their professionalism when their preconceived opinions and values about gender and transgender were confronted.

Discussion:

Our findings demonstrate the need of continuous efforts on assessing learning needs as well as addressing preconceived opinions and values of HCP. By gaining knowledge and self-confidence in the care of transgender individuals undergoing FP, a professional care for transgender people can be achieved and a safe environment can be established for the patients. This in turn may alleviate some of the distress that may arise when transgender men undergo FP.

Impact of Exogenous Testosterone on Reproduction in Transgender Men

Studies show that a subset of transgender men desire children; however, there is a paucity of literature on the effect of gender-affirming testosterone therapy on reproductive function. In this manuscript, we will review the process of gender-affirming hormone therapy for transgender men and what is known about ovarian and uterine consequences of testosterone exposure in transgender men; draw parallels with existing animal models of androgen exposure; summarize the existing literature on parenting experiences and desires in transgender people; discuss considerations for assisted reproductive technologies and fertility preservation; and identify gaps in the literature and opportunities for further research.

Parental desire and fertility preservation in assigned male at birth transgender people living in Belgium

Introduction: Transgender people who chose to proceed with gender affirming hormonal and/or surgical therapy, may face reduced options for fulfilling their parental desire in the future. The ideas and concerns of adult transgender people regarding fertility preservation and parental desire have never been reported in a large, non-clinical sample of assigned male at birth (AMAB) transgender people. Methods: A web-based survey on fertility and parenthood in (binary and non-binary) transgender people was conducted in Belgium. AMAB people were selected for this analysis. Results: We included 254 AMAB persons, of which 196 (77.2%) self-identified as transgender women (TW), 14 (5.5%) as cross-dressers and 44 (17.3%) as gender non-binary (GNB) people. Fifty-five (21.6%) respondents had a current/future parental desire, parental desire was already fulfilled in 81 (31.9%) and not present in 57 people (22.4%) (other: 19.2%). TW were more likely to express a parental desire, compared to GNB people and cross-dressers (P = 0.004). In total, 196 AMAB people previously sought medical assistance, of which 30 (15.3%) considered the loss of fertility due to the transitioning process undesirable. The majority (68.2%) did not want fertility preservation (FP). Fourteen people (9.8%) had proceeded with FP. The main reasons not to proceed with FP included not feeling the need (70; 68.0%), not desiring a genetic link with (future) child(ren) (20; 19.4%) and having to postpone hormone treatment (15; 14.6%). TW were more likely to have a parental desire and to have cryopreserved or to consider cryopreserving gametes, compared to GNB people. Conclusion: Parental desire and FP use were lower in the current non-clinical sample than in previous research on clinical samples. This can possibly be explained by the barriers transgender people face when considering fertility options, including postponing hormone therapy. Also, GNB persons have different needs for gender affirming treatment and FP.

Health considerations for transgender women and remaining unknowns: a narrative review

Transgender (trans) women (TW) were assigned male at birth but have a female gender identity or gender expression. The literature on management and health outcomes of TW has grown recently with more publication of research. This has coincided with increasing awareness of gender diversity as communities around the world identify and address health disparities among trans people. In this narrative review, we aim to comprehensively summarize health considerations for TW and identify TW-related research areas that will provide answers to remaining unknowns surrounding TW's health. We cover up-to-date information on: (1) feminizing gender-affirming hormone therapy (GAHT); (2) benefits associated with GAHT, particularly quality of life, mental health, breast development and bone health; (3) potential risks associated with GAHT, including cardiovascular disease and infertility; and (4) other health considerations like HIV/AIDS, breast cancer, other tumours, voice therapy, dermatology, the brain and cognition, and aging. Although equally deserving of mention, feminizing gender-affirming surgery, paediatric and adolescent populations, and gender nonbinary individuals are beyond the scope of this review. While much of the data we discuss come from Europe, the creation of a United States transgender cohort has already contributed important retrospective data that are also summarized here. Much remains to be determined regarding health considerations for TW. Patients and providers will benefit from larger and longer prospective studies involving TW, particularly regarding the effects of aging, race and ethnicity, type of hormonal treatment (e.g. different oestrogens, anti-androgens) and routes of administration (e.g. oral, parenteral, transdermal) on all the topics we address.

Fertility Preservation in Male to Female Transgender Patients

Gender dysphoria, or the incongruence between gender identification and sex assigned at birth with associated discomfort or distress, manifests in transgender patients, whose multifaceted care includes puberty suppression, cross-sex hormonal therapy, and gender-affirming surgery. Discussion of fertility preservation (FP) is paramount because many treatments compromise future fertility, and although transgender patients demonstrate desire for children, use of FP remains low for a plethora of reasons. In transgender women, established FP options include ejaculated sperm cryopreservation, electroejaculation, or testicular sperm extraction. Further research is needed regarding reproductive health and FP in transgender patients.

Transfeminine Hormone Therapy

Transgender women often seek hormone therapy to attain feminine physical features congruent with their gender identity. The aim of feminizing hormone therapy (FHT) is to provide suppression of endogenous testosterone and to maintain estradiol levels within the normal female range. Overall, FHT is safe if provided under supervision of an experienced health care provider and has been shown to improve quality of life. Data on care of transgender women are scarce and high-quality evidence-based recommendations are lacking. This article aims to review the published literature on FHT and provide guidance to clinicians caring for transgender women.

Options for Fertility Treatments for Trans Women in Germany

Fertility preservation in trans women is a crucial but thus far neglected component in the gender confirming treatment in Germany. It is difficult for trans women to access reproductive health care because centers offering treatment, psychological guidance, gender confirming surgery, as well as reproductive health services are scarce in Germany. Legal, social, or financial issues as well as individual patient comorbidities prevent trans women from receiving appropriate counselling. This review provides an overview on options of fertility preservation in trans women. We consider recent publications on testicular regression at the time of gender confirming surgery demonstrating presence of sperm or at least spermatogonia in the majority of tissues. This may open options for cryopreservation of sperm or testicular stem cells in trans women even at the final stage of transition. Hence, standardized urological procedures (i.e., sperm cryopreservation after masturbation or sperm extraction from the testicular tissue) and experimental approaches (cryopreservation of testicular tissue with undifferentiated spermatogonia) can be offered best at the initiation but also during the gender confirming process. However, counselling early in the gender confirming process increases the chances of fertility preservation because gender confirming hormone therapy has an impact on spermatogenesis.

Endocrinology of Transgender Medicine

Gender-affirming treatment of transgender people requires a multidisciplinary approach in which endocrinologists play a crucial role. The aim of this paper is to review recent data on hormonal treatment of this population and its effect on physical, psychological, and mental health. The Endocrine Society guidelines for transgender women include estrogens in combination with androgen-lowering medications. Feminizing treatment with estrogens and antiandrogens has desired physical changes, such as enhanced breast growth, reduction of facial and body hair growth, and fat redistribution in a female pattern. Possible side effects should be discussed with patients, particularly those at risk for venous thromboembolism. The Endocrine Society guidelines for transgender men include testosterone therapy for virilization with deepening of the voice, cessation of menses, and increases of muscle mass and facial and body hair. Owing to the lack of evidence, treatment of gender nonbinary people should be individualized. Young people may receive pubertal suspension, consisting of GnRH analogs, later followed by sex steroids. Options for fertility preservation should be discussed before any hormonal intervention. Morbidity and cardiovascular risk with cross-sex hormones is unchanged among transgender men and unclear among transgender women. Sex steroid-related malignancies can occur but are rare. Mental health problems such as depression and anxiety have been found to reduce considerably following hormonal treatment. Future studies should aim to explore the long-term outcome of hormonal treatment in transgender people and provide evidence as to the effect of gender-affirming treatment in the nonbinary population.

Queering abortion rights: notes from Argentina

In recent years, there have been calls in activist spaces to 'queer' abortion rights advocacy, to incorporate non-normative notions of gender identity and sexuality into abortion struggles and services. Argentina provides an interesting site in which to examine these developments, since there is a longstanding movement for abortion rights in a context of illegal abortion and a recent ground-breaking Gender Identity Law that recognises key trans rights. In this paper, we analyse public documents from the abortion rights movement's main coalition - the National Campaign for the Right to Legal, Safe and Free Abortion - alongside interviews with 19 Campaign activists to examine shifts and tensions in contemporary abortion rights activism. We trace the incorporation of trans-inclusive language into the newly proposed abortion rights bill and conclude by pointing to contextual factors that may limit or enhance the further queering of abortion rights.

Sperm cryopreservation of transgender individuals: trends and findings in the past decade

OBJECTIVES

Awareness and acceptance of transgenderism have increased in the last two decades. There is limited literature regarding the incidence and semen characteristics of transwomen banking spermatozoa. We sought to assess the incidence of sperm cryopreservation of transgender individuals compared with the cisgender population in the last 10 years. Semen parameters were also compared between the two groups.

MATERIALS AND METHODS

We performed a retrospective analysis of sperm cryopreservation performed at a single center from 2006 through 2016. Using available data on indications for banking and prior hormonal therapy status, we isolated healthy transgender and cisgender cohorts for semen parameter comparison. Linear regression was used to compare the incidence trends. Semen parameters were compared using the generalized estimating equations method. The rates of semen parameter abnormality of each group were compared using chi-square test. Semen parameter abnormalities were defined using WHO 2010 reference values.

RESULTS

We analyzed 194 transgender samples and 2327 cisgender samples for a total of 84 unique transgender sperm bankers and 1398 unique cisgender sperm bankers. The number of transgender sperm bankers increased relative to cisgender sperm bankers from 2006 to 2016. Following exclusion of cisgender sperm bankers with health issues that might impact semen quality and transgender sperm bankers with known prior hormonal therapy, we compared the semen parameters of 141 healthy cisgender sperm bankers and 78 healthy transgender sperm bankers. The transgender sperm bankers demonstrated lower sperm concentration, total motile sperm count, and post-thaw sperm parameters. The transgender sperm bankers also demonstrated a higher incidence of oligozoospermia.

CONCLUSIONS

This is the largest report to date on the incidence of transgender sperm cryopreservation and comparison of semen characteristics with cisgender sperm bankers. The data reveal an increased incidence of transgender sperm banking as well as poorer semen parameters of transgender individuals compared with cisgender controls.

Hormonal Management for Transfeminine Individuals

Transfeminine individuals are treated with estradiol and anti-androgen agents to transition to a more feminine appearance. The physical changes that occur with estradiol therapy include breast development, body fat redistribution, and decreased muscle mass. Transfeminine treatment regimens require monitoring and dose adjustments to achieve appropriate physiologic targets to enhance feminization and decrease risk of adverse outcomes. Adverse effects associated with estradiol use include thromboembolic disease, macroprolactinoma, breast cancer, coronary artery disease, cerebrovascular disease, cholelithiasis, and hypertriglyceridemia. Benefits of hormonal treatment may include both an improvement in quality of life and a decrease in gender dysphoria.

Fertility preservation options in transgender people: A review

Gender affirming procedures adversely affect the reproductive potential of transgender people. Thus, fertility preservation options should be discussed with all transpeople before medical and surgical transition. In transwomen, semen cryopreservation is typically straightforward and widely available at fertility centers. The optimal number of vials frozen depends on their reproductive goals and treatment options, therefore a consultation with a fertility specialist is optimal. Experimental techniques including spermatogonium stem cells (SSC) and testicular tissue preservation are technologies currently under development in prepubertal individuals but are not yet clinically available. In transmen, embryo and/or oocyte cryopreservation is currently the best option for fertility preservation. Embryo cryopreservation requires fertilization of the transman's oocytes with a donor or partner's sperm prior to cryopreservation, but this limits his future options for fertilizing the eggs with another partner or donor. Oocyte cryopreservation offers transmen the opportunity to preserve their fertility without committing to a male partner or sperm donor at the time of cryopreservation. Both techniques however require at least a two-week treatment course, egg retrieval under sedation and considerable cost. Ovarian tissue cryopreservation is a promising experimental method that may be performed at the same time as gender affirming surgery but is offered in only a limited amount of centers worldwide. In select places, this method may be considered for prepubertal children, adolescents, and adults when ovarian stimulation is not possible. Novel methods such as in-vitro activation of primordial follicles, in vitro maturation of immature oocytes and artificial gametes are under development and may hold promise for the future.

Process and Pitfalls of Sperm Cryopreservation

Sperm cryopreservation has been utilized routinely for over 40 years to preserve fertility in men undergoing cancer therapy and allow conception for infertile couples. This article provides a concise and up-to-date review of the literature and covers the latest advances in sperm cryopreservation and its array of clinical indications. Over recent years, the scope of clinical indications used for sperm cryopreservation has expanded widely. Consequently, more patient groups are eligible for sperm freezing, requiring specialist resources and higher running costs. Although sperm cryopreservation prior to cancer therapy is readily available in many countries, referral rates by oncology specialists and levels of patient engagement with cryopreservation services are both reported as low. Furthermore, sperm banking continues to raise ethical issues such whether sperm donation should be anonymous and whether sperm can be utilized posthumously by the surviving partner without consent from the patient. This review focuses on the technological advances and ethical controversies in sperm cryopreservation, and how better understanding of these issues could lead to improved access to fertility preserving treatment for patients.

Fertility treatment for the transgender community: a public opinion study

PURPOSE

The purposes of this study were to evaluate public opinion regarding fertility treatment and gamete cryopreservation for transgender individuals and identify how support varies by demographic characteristics.

METHODS

This is a cross-sectional web-based survey study completed by a representative sample of 1111 US residents aged 18-75 years. Logistic regression was used to calculate odd ratios (ORs) and 95% confidence intervals (CIs) of support for/opposition to fertility treatments for transgender people by demographic characteristics, adjusting a priori for age, gender, race, and having a biological child.

RESULTS

Of 1336 people recruited, 1111 (83.2%) agreed to participate, and 986 (88.7%) completed the survey. Most respondents (76.2%) agreed that "Doctors should be able to help transgender people have biological children." Atheists/agnostics were more likely to be in support (88.5%) than Christian-Protestants (72.4%; OR = 3.10, CI = 1.37-7.02), as were younger respondents, sexual minorities, those divorced/widowed, Democrats, and non-parents. Respondents who did not know a gay person (10.0%; OR = 0.20, CI = 0.09-0.42) or only knew a gay person without children (41.4%; OR = 0.29, CI = 0.17-0.50) were more often opposed than those who knew a gay parent (48.7%). No differences in gender, geography, education, or income were observed. A smaller majority of respondents supported doctors helping transgender minors preserve gametes before transitioning (60.6%) or helping transgender men carry pregnancies (60.1%).

CONCLUSIONS

Most respondents who support assisted and third-party reproduction also support such interventions to help transgender people have children.

Review of the Transgender Literature: Where Do We Go from Here?

Purpose: The “transgender tipping point” has brought transgender social and health issues to the forefront of American culture. However, medical professionals have been lagging in academic research with a transgender-specific focus resulting in significant knowledge gaps in dealing with the care of our transgender patients. The aim of this article is to analyze all published Medline-available transgender-specific articles, identify these knowledge gaps, and direct future research to where it is most needed.

Methods: We surveyed all Medline-available articles up to June 2016 using a combination of medical subject headings and keywords in titles and abstracts. Articles meeting inclusion criteria were reviewed, categorized, and analyzed for content and study design.

Results: In our review of the literature, we identified 2405 articles published from January 1950 to June 2016 that focused on transgender health, primarily in the fields of surgery, mental health, and endocrinology.

Conclusion: Significant knowledge gaps were found across the subspecialties, and there was a lack of prospective robust research and representation of transgender-specific data in the core medical journals. More data and research are needed to bridge the knowledge gaps that currently exist and improve the care of the transgender community.

Oestrogen and anti-androgen therapy for transgender women

Transgender women experience lifelong gender dysphoria due to a gender assignment at birth that is incongruent with their gender identity. They often seek hormone therapy, with or without surgery, to improve their gender dysphoria and to better align their physical and psychological features with a more feminine gender role. Some of the desired physical changes from oestrogen and anti-androgen therapy include decreased body and facial hair, decreased muscle mass, breast growth, and redistribution of fat. Overall the risks of treatment are low, but include thromboembolism, the risk of which depends on the dose and route of oestrogen administration. Other associated conditions commonly seen in transgender women include increased risks of depression and osteoporosis. The risk of hormone-sensitive cancer seems to be low in transgender women, with no increased risk of breast cancer compared with women and no increase in prostate cancer when compared with men. The evidence base for the care of transgender women is limited by the paucity of high-quality research, and long-term longitudinal studies are needed to inform future guidelines.

Non-binary or genderqueer genders

Some people have a gender which is neither male nor female and may identify as both male and female at one time, as different genders at different times, as no gender at all, or dispute the very idea of only two genders. The umbrella terms for such genders are 'genderqueer' or 'non-binary' genders. Such gender identities outside of the binary of female and male are increasingly being recognized in legal, medical and psychological systems and diagnostic classifications in line with the emerging presence and advocacy of these groups of people. Population-based studies show a small percentage--but a sizable proportion in terms of raw numbers--of people who identify as non-binary. While such genders have been extant historically and globally, they remain marginalized, and as such--while not being disorders or pathological in themselves--people with such genders remain at risk of victimization and of minority or marginalization stress as a result of discrimination. This paper therefore reviews the limited literature on this field and considers ways in which (mental) health professionals may assist the people with genderqueer and non-binary gender identities and/or expressions they may see in their practice. Treatment options and associated risks are discussed.

Fertility options in transgender people

Hormonal and surgical treatments for transgender people have a devastating effect on the possibility for these patients to reproduce. Additionally, transgender people tend to start sex reassignment treatment at a young age, when reproductive wishes are not yet clearly defined nor fulfilled. The most recent Standards of Care of the World Professional Association for Transgender Health recommend clearly informing patients regarding their future reproductive options prior to initiation of treatment. This review gives an overview of the current knowledge and state-of-the-art techniques in the field of fertility preservation for transgender people. Where genital reconstructive surgery definitely results in sterility, hormone therapy on the other hand also has an important, but partially reversible impact on fertility. The current fertility preservation options for trans men are embryo cryopreservation, oocyte cryopreservation and ovarian tissue cryopreservation. For trans women, sperm cryopreservation, surgical sperm extraction and testicular tissue cryopreservation are possible. Although certain fertility preservation techniques could be applicable in a standardized manner based on clear biological criteria, the technique that eventually will be performed should be the preferred choice of the patient after extended explanation of all possible options.

Prevalence of Pregnancy Involvement Among Canadian Transgender Youth and its Relation to Mental Health, Sexual Health, and Gender Identity

While little research has been conducted into the reproductive experiences of transgender people, available evidence suggests that like cisgender people, most transgender people endorse a desire for these experiences. This study explores the pregnancy experiences and related health factors among transgender and gender-diverse 14-25 year olds using a national Canadian sample (N = 923). Results indicated that 26 (5%) transgender youth reported a pregnancy experience in the past and the prevalence among 14-18 year olds was comparable to population-based estimates using the same question in the British Columbia Adolescent Health Survey. Transgender youth with a history of pregnancy involvement reported a diverse range of gender identities, and this group did not differ from the remainder of the sample on general mental health, social supports, and living in felt gender. This group did report over six times greater likelihood of having been diagnosed with a sexually transmitted infection by a doctor (19%), but did they not differ in reported contraception use during last sexual intercourse. These findings suggest that pregnancy involvement is an issue that should not be overlooked by health professionals working with transgender youth and that this group has particular sexual health needs.

Fertility-related research needs among women at the margins

Fertility-related research encompasses fertility intentions, preconception care, research amongst pregnant women, and post-partum outcomes of mothers and children. However, some women remain under-represented within this domain of study. Women frequently missing within fertility-related research include those who are already the most vulnerable to health disparities, including female sex workers, lesbian, gay, bisexual, and transgender women, women living with HIV, and women who use drugs. Yet characterization of the needs of these women is important, given their unique fertility-related concerns, including risks and barriers to care emanating from social stigmas and discrimination. This synthesis provides an overview of fertility-related evidence, highlighting where there are clear research gaps among marginalized women and the potential implications of these data shortfalls. Overall, research among marginalized women to date has addressed pregnancy prevention and in some cases fertility intentions, but the majority of studies have focused on post-conception pregnancy safety and the well-being of the child. However, among female sex workers specifically, data on pregnancy safety and the well-being of the child are largely unavailable. Within each marginalized group, preconception care and effectiveness of conception methods are consistently understudied. Ultimately, the absence of epidemiologic, clinical and programmatic evidence limits the availability and quality of reproductive health services for all women and prevents social action to address these gaps.

Toward a broader conceptualization of trans women's sexual health

Research on the sexual health of trans women (male-to-female spectrum transgender people), has focused primarily on sexual response and satisfaction after initiating hormone treatment or undergoing genital surgery, or on HIV-related sexual risk among trans women sexually active with cisgender (cis, i.e., non-trans) men. Given that these situations are not representative of the majority of trans women at most points in the lifecourse, a broader discussion is needed to provide sex educators, therapists, clinicians, and researchers, as well as trans women and their partners, with information needed to promote sexual health. Drawing on the theoretical constructs of cisnormativity and cissexism, as well as previously published and new data from Trans PULSE, a community-based study of trans health in Ontario, we discuss the social context and sexual realities of trans women's lives.
