Response of the human testis to long-term estrogen treatment: morphology of Sertoli cells, Leydig cells and spermatogonial stem cells

Patient education and counselling of fertility preservation for transgender and gender diverse people: A scoping review

Objectives

To examine patient education, counselling practices, decision aids, and education resources related to fertility preservation for transgender and gender diverse (TGD) youth and young adults.

Methods

A scoping review was conducted using a comprehensive literature search (Ovid MEDLINE, PubMed Medline, OVID Embase, Ovid PsychoINFO, and Cochrane Central Register of Controlled Trials) conducted from 1806 to October 21, 2022. Inclusion criteria involved abstracts and articles on patient education, counselling, decision aids or education resources regarding fertility preservation for TGD youth and adults.

Results

Of 1,228 identified articles and abstracts, only six articles met inclusion criteria. Three key themes were identified: (1) patient education and counselling practices (n = 4), with majority of patients receiving fertility preservation counselling at their respective centres; (2) decision aids and strategies for clinicians on fertility preservation for TGD individuals (n = 2) and; (3) patient education resources (n = 1). There was a paucity of literature on decision aids and patient education resources.

Conclusions

This study highlights the need to further develop and evaluate decision aids for healthcare providers and patient education resources, including eLearning modules, around fertility preservation for TGD individuals.

A Mouse Model to Investigate the Impact of Gender Affirming Hormone Therapy with Estradiol on Reproduction

Gender-affirming hormone therapy (GAHT) can help transgender and/or gender diverse (TGD) individuals achieve emobidment goals that align with their transition needs. Clinical evidence from estradiol (E)-GAHT patients indicate widespread changes in tissues sensitive to E and testosterone (T), particularly in the reproductive system. Notably, E-GAHTs effects on hormones and reproduction vary greatly between patients. With the goal of informing clinical research and practice for TGD individuals taking E, this study examines intact male mice implanted with capsules containing one of three different E doses (low 1.25 mg; mid 2.5 mg; high 5 mg), or a blank control capsule. All E-GAHT doses suppress T and follicle stimulating hormone levels while elevating E levels. Only the high E-GAHT dose significantly supresses luteinizing hormone levels. All E-GAHT doses affect epididymis tubule size similarly while seminiferous tubule morphology and bladder weight changes are dose-dependent. E-GAHT does not alter the presence of mature sperm, though E-exposed sperm have altered motility. These data represent the first evidence that mouse models offer an effective tool to understand E-GAHTs impact on reproductive health and the dose-dependent effects of this model permit examinations of diverse patient outcomes.

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.

Reproductive and Fertility Knowledge and Attitudes Among Transgender and Gender-Expansive Youth: A Replication and Extension

Purpose

This study sought to replicate and expand a previous pilot investigation of reproductive knowledge, attitudes toward fertility and parenthood, and sources of information on these topics among transgender and gender-expansive (TGE) youth.

Methods

The Yale Pediatric Gender Program (YPGP) Reproductive Knowledge and Experiences Survey (YPGP-RKES) was administered to 70 TGE adolescents receiving care at an interdisciplinary clinic providing gender-affirming health care at an academic medical center. Data gathered included sources of information on reproduction and fertility, concerns about future parenthood and reproduction, and interest in different types of parenthood.

Results

Over a third (39.1%) of participants reported it was important to them to have a child one day, while only a small proportion (23.2%) reported an interest in biological parenthood. A plurality of participants (37.3%) reported at least one concern about future fertility. The number of reproductive concerns did not differ by age or treatment (puberty blockers or gender-affirming hormones vs. no treatment) status. With respect to needs for more information and sources of information, most (56.5%) participants received information about fertility issues before this study, with the most cited source of information being online research.

Conclusions

The current study replicated and extended previous findings on the reproductive attitudes and knowledge of TGE adolescents. Understanding the informational needs and priorities of adolescent TGE patients presenting for medical treatment will allow providers to give more robust patient education. This will, in turn, facilitate patients' ability to provide fully informed consent for treatment that aligns with their fertility and reproductive priorities and goals.

Fertility preservation and realignment in transgender women

Medical care for transgender people is multi-faceted and attention to individual reproductive aspirations and planning are an essential, yet often overlooked aspect of care. Given the impact of hormonal therapy and other gender affirmation procedures on reproductive function, extensive counselling and consideration of fertility preservation is recommended prior to their commencement. This review article explores the reproductive aspirations of transgender women and considers the current disparity between stated desires regarding utilisation of fertility preservation services. Current fertility preservation options and prospective treatments currently showing promise in the research arena are explored.

Associations between seminal plasma triclosan and low sperm quality: A case-control study

OBJECTIVE

Triclosan (TCS), a novel endocrine disrupter, has induced widespread human exposure due to its widespread use in personal care products. Environmental TCS exposure was suggested to be associated with human semen quality. However, little is known about seminal plasma TCS concentration and the risk of low sperm quality. This case-control study is established to examine the relationship between seminal plasma TCS and the risk of low sperm quality.

STUDY DESIGN

One hundred men with low sperm quality as cases and one hundred normal men as controls were recruited a fertility clinic in Shijiazhuang, China, during 2018-2019. Seminal plasma TCS concentration was determined using an ultrahigh-performance liquid chromatography-tandem mass spectrometer (UPLC-MS/MS). Sperm concentration, sperm count, sperm motility and sperm progressive motility were evaluated according to World Health Organization (WHO) guidelines to assess the sperm quality. We used the Mann-Whitney rank-sum test and Kruskal-Wallis test to assess the differences of seminal plasma TCS concentration between the cases and the controls. In addition, logistic regression analysis was used to estimate the associations between seminal plasma TCS concentrations and low sperm quality risk adjusting for age, body mass index (BMI), abstinence time, smoking, and drinking RESULTS AND CONCLUSIONS: The level of seminal plasma TCS was observed slightly but not significantly higher in the case group than the control group. We also observed significant association between seminal plasma TCS concentrations and semen parameters in both control and case groups. Moreover, the seminal plasma TCS levels at the fourth quartile were found to be more likely to exhibit low sperm quality risk with increased adjusted odds ratios of 2.36 (95% confidence interval 1.03-5.39) compared to the first quartile. Our results reveal that seminal plasma TCS concentration was positively associated with low sperm quality risk.

Successful restoration of spermatogenesis following gender-affirming hormone therapy in transgender women

Increasing numbers of transgender individuals are presenting for gender-affirming medical care. For trans women, gender-affirming hormone therapy (GAHT) promotes feminization but also inhibits spermatogenesis. There is a common untested assumption that this inhibition is permanent, resulting in infertility. In this longitudinal study, we report the recovery of viable spermatozoa in nine trans women who stopped GAHT for reproductive purposes. Our preliminary findings suggest that the negative impact of GAHT on spermatogenesis can be reversed, casting doubt on previous claims that GAHT in trans women inevitably leads to permanent infertility. Larger studies are needed to confirm our findings, which have implications not only for fertility counseling and the reproductive options of transgender individuals but also efforts to restrict access to GAHT based on fertility grounds.

Préservation de la fertilité chez les personnes transgenres

La majorité des personnes transgenres envisage de fonder une famille, mais leur fertilité peut être altérée par l’affirmation du genre. L’hormonothérapie peut affecter durablement la production de gamètes, notamment chez les femmes trans. La chirurgie de réassignation sexuelle entraîne une stérilité définitive. En France, des réseaux de professionnels de santé se sont organisés. Ils recommandent l’accès à la préservation de la fertilité dans le cadre de la transidentité. Cependant, le recueil de gamètes reste souvent difficile en raison de l’incongruence hormonale pour les femmes trans, ou du caractère invasif de la procédure pour les hommes trans. De futures études permettront de statuer sur l’utilisation des gamètes autoconservés.

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 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.

Histological study on the influence of puberty suppression and hormonal treatment on developing germ cells in transgender women

STUDY QUESTION

Can transgender women cryopreserve germ cells obtained from their orchiectomy specimen for fertility preservation, after having used puberty suppression and/or hormonal treatment?

SUMMARY ANSWER

In the vast majority of transgender women, there were still immature germ cells present in the orchiectomy specimen, and in 4.7% of transgender women—who all initiated medical treatment in Tanner stage 4 or higher—mature spermatozoa were found, which would enable cryopreservation of spermatozoa or testicular tissue after having used puberty suppression and/or hormonal treatment.

WHAT IS KNOWN ALREADY

Gender affirming treatment (i.e. puberty suppression, hormonal treatment, and subsequent orchiectomy) impairs reproductive function in transgender women. Although semen cryopreservation is generally offered during the transition process, this option is not feasible for all transgender women (e.g. due to incomplete spermatogenesis when initiating treatment in early puberty, in case of inability to masturbate, or when temporary cessation of hormonal treatment is too disruptive). Harvesting mature spermatozoa, or testicular tissue harboring immature germ cells, from orchiectomy specimens obtained during genital gender-affirming surgery (gGAS) might give this group a chance of having biological children later in life. Previous studies on spermatogenesis in orchiectomy specimens showed conflicting results, ranging from complete absence of germ cells to full spermatogenesis, and did not involve transgender women who initiated medical treatment in early- or late puberty.

STUDY DESIGN, SIZE, DURATION

Histological and immunohistochemical analyses were performed on orchiectomy specimens from 214 transgender women who underwent gGAS between 2006 and 2018. Six subgroups were identified, depending on pubertal stage at initiation of medical treatment (Tanner stage 2-3, Tanner stage 4-5, adult), and whether hormonal treatment was continued or temporarily stopped prior to gGAS in each of these groups.

PARTICIPANTS/MATERIALS, SETTING, METHODS

All transgender women used a combination of estrogens and testosterone suppressing therapy. Orchiectomy specimen sections were stained with Mayer’s hematoxylin and eosin and histologically analyzed to assess the Johnsen score and the ratio of most advanced germ cell types in at least 50 seminiferous tubular cross-sections. Subsequently, immunohistochemistry was used to validate these findings using spermatogonia, spermatocytes or spermatids markers (MAGE-A3/A4, γH2AX, Acrosin, respectively). Possibilities for fertility preservation were defined as: preservation of spermatozoa, preservation of spermatogonial stem cells or no possibilities (in case no germ cells were found). Outcomes were compared between subgroups and logistic regression analyses were used to assess the association between the duration of hormonal treatment and the possibilities for fertility preservation.

MAIN RESULTS AND THE ROLE OF CHANCE

Mature spermatozoa were encountered in 4.7% of orchiectomy specimens, all from transgender women who had initiated medical treatment in Tanner stage 4 or higher. In 88.3% of the study sample orchiectomy specimens only contained immature germ cells (round spermatids, spermatocytes or spermatogonia, as most advanced germ cell type). In 7.0%, a complete absence of germ cells was observed, all these samples were from transgender women who had initiated medical treatment in adulthood. Cessation of hormonal treatment prior to gGAS did not affect the presence of germ cells or their maturation stage, nor was there an effect of the duration of hormonal treatment prior to gGAS.

LIMITATIONS, REASONS FOR CAUTION

Since data on serum hormone levels on the day of gGAS were not available, we were unable to verify if the transgender women who were asked to temporarily stop hormonal treatment 4 weeks prior to surgery actually did so, and if people with full spermatogenesis were compliant to treatment.

WIDER IMPLICATIONS OF THE FINDINGS

There may still be options for fertility preservation in orchiectomy specimens obtained during gGAS since a small percentage of transgender women had full spermatogenesis, which could enable cryopreservation of mature spermatozoa via a testicular sperm extraction procedure. Furthermore, the vast majority still had immature germ cells, which could enable cryopreservation of testicular tissue harboring spermatogonial stem cells. If maturation techniques like in vitro spermatogenesis become available in the future, harvesting germ cells from orchiectomy specimens might be a promising option for those who are otherwise unable to have biological children.

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.

Incidence of testicular cancer in trans women using gender-affirming hormonal treatment: a nationwide cohort study

Objective

To assess the incidence of testicular cancer in trans women (male sex assigned at birth, female gender identity) using gender‐affirming hormonal treatment.

Patients and Methods

Data of trans women starting hormonal treatment at our gender identity clinic between 1972 and 2017 were linked to the national pathology database to obtain testicular cancer diagnoses. The standardised incidence ratio (SIR) was calculated using the number of observed testicular cancer cases in our cohort and the number of expected cases based on age‐specific Dutch incidence rates. Subgroup analyses were performed in testicular tissues sent for histopathological analysis at the time of bilateral orchidectomy, and when follow‐up exceeded 5 years.

Results

The cohort consisted of 3026 trans women with a median follow‐up time of 2.3 interquartile range (IQR) (1.6–3.7) years. Two testicular cancer cases were identified whilst 2.4 cases were expected (SIR 0.8, 95% confidence interval 0.1–2.8). In addition, one testicular cancer case was encountered in an orchidectomy specimen (0.1%). In the 523 trans women with a follow‐up time of >5 years (median [IQR] 8.9 [6.4–13.9] years), no testicular cancer was observed.

Conclusion

Testicular cancer risk in trans women is similar to the risk in cis men. The testicular cancer cases occurred within the first 5 years after commencing hormonal treatment, and the percentage of cases encountered at the time of bilateral orchidectomy was low. As no testicular cancer was observed in trans women with a long follow‐up period, long‐term hormonal treatment does not seem to increase testicular cancer risk.

Take the T out, put the T in: Gender-affirming hormones in youth

BACKGROUND

An increasing number of adolescents are seeking gender care at clinics and hospital programs, and requesting gender-affirming hormonal treatment. The interventions can either include suppression of testosterone and introduction of estrogen, or suppression of estrogen and introduction of testosterone.

AIMS

This review article focuses on the psychosocial experiences of youth who have completed their endogenous puberty and are now requesting one of these two forms of gender-affirming hormonal treatment. We investigate the comparative profiles of these two subgroups of transgender/gender-expansive youth.

MATERIALS AND METHODS

Review of research data, established standards of care and practice guidelines, and clinical observations.

RESULTS

Differences and similarities are noted and discussed in several realms: gender-related experiences prior to receiving hormonal treatment; the relationship between the physical changes and psychological experiences that accompany the introduction of testosterone or suppression of testosterone with replacement with estrogen; the intrapersonal and interpersonal implications of the treatment; considerations of fertility preservation for future family building; the role of the family in the decision-making process prior to starting a course of hormone therapy; and the capacity of youth to make informed decisions about these partially irreversible medical interventions.

DISCUSSION

Medical providers who offer gender-affirming hormonal care to youth should work with the family and allied professionals to assure that the youth's gender health is enhanced, barriers to care are removed, and mental health risks are reduced, whether the T is coming out or going in.

CONCLUSION

The cohort of youth who come to medical providers after completing puberty, and request gender-affirming hormones in the form of increases or reductions in T have a great deal in common, and also extensive variation among them.

Characterisation of testicular function and spermatogenesis in transgender women

STUDY QUESTION

Does gender-affirming treatment prevent full spermatogenesis in transgender women (TW)?

SUMMARY ANSWER

Adequate hormonal therapy (HT) leads to complete suppression of spermatogenesis in most TW, if serum testosterone levels within female reference ranges are obtained.

WHAT IS KNOWN ALREADY

Gender-affirming treatment in transgender individuals may involve gender-affirming HT. The effects on spermatogenesis in TW remain unclear. In order to add information from a referral centre for transgender care, we wish to compare results of earlier studies with our population of TW who received a standard hormone treatment.

STUDY DESIGN, SIZE, DURATION

This was a prospective cohort study part of the European Network for the Investigation of Gender Incongruence (ENIGI), conducted between 15 February 2010 and 30 September 2015. There were 162 TW were included in the ENIGI study at the Ghent University Hospital in Belgium. Participants are included in ENIGI when they first start HT, and follow-up visits occur over the next 3 years.

PARTICIPANTS/MATERIALS, SETTING METHODS

The study included 97 TW who initiated HT with cyproterone acetate (CPA) plus oestrogens and proceeded with gonadectomy at the Ghent University Hospital. Testicular tissue retrieved during gonadectomy was processed and stained for four different germ cell markers by the Biology of the Testis lab at the Vrije Universiteit Brussel. Subsequent immunohistochemical staining was performed for melanoma-associated antigen A4 (MAGE-A4, marker for spermatogonia and early spermatocytes), boule homologue, RNA-binding protein (BOLL, marker for secondary spermatocytes and round spermatids), cAMP-responsive element modulator (CREM, marker for round spermatids) and acrosin (marker for acrosome visualization). Serum levels of sex steroids were measured prior to surgery.

MAIN RESULTS AND THE ROLE OF CHANCE

Suppressed testosterone levels (<50 ng/dl) were found in 92% of the participants prior to surgery. The mean time between initiation of HT and surgery was 685 days. In 88% (85/97) of the sections, MAGE-A4 staining was positive. Further staining could not reveal complete spermatogenesis in any participant.

LIMITATIONS, REASONS FOR CAUTION

Testicular function of the participants prior to initiation of HT was not assessed, although all participants presented with cisgender male serum testosterone values before initiation of HT. The current study only reports on people using CPA at a fixed dose and may therefore not be applicable to all TW.

WIDER IMPLICATIONS OF THE FINDINGS

HT leads to complete suppression of spermatogenesis in most TW, if serum testosterone levels within female reference ranges are obtained. Serum testosterone levels are associated with the sperm maturation rate. It is important to discuss sperm preservation before the start of hormone therapy. If serum testosterone levels remain higher, spermatogenesis may still occur.

STUDY FUNDING/COMPETING INTEREST(S)

D.V.S. is a post-doctoral fellow of the Fonds Wetenschappelijk Onderzoek (FWO; 12M2819N). Processing of the testis specimens was funded by the Biology of The Testes (BITE) research group (Department of Reproduction, Genetics and Regenerative medicine at Vrije Universiteit Brussel (VUB)). There are no competing interests.

Histologic Findings in Surgical Pathology Specimens From Individuals Taking Feminizing Hormone Therapy for the Purpose of Gender Transition: A Systematic Scoping Review

CONTEXT.—

Transgender women experience health disparities in all areas of medicine. Within surgical pathology, knowledge gaps relating to the concepts of transgender care exist. Medical transition for transgender women and transfeminine persons may involve hormone therapy and/or surgery to feminize the body. Understanding the common histologic changes in specimens from feminizing surgeries, as well as other specimens from patients on feminizing hormone therapy, will aid surgical pathologists in providing better care to this unique patient population.

OBJECTIVE.—

To summarize histologic findings in surgical pathology specimens from transgender women taking feminizing hormones.

DATA SOURCES.—

A systematic review of the OVID Medline and PubMed databases was performed to identify all studies describing histologic findings in surgical pathology specimens from transgender women from 1946 to 2019.

CONCLUSIONS.—

Much of the literature to date describing histologic findings in transgender women comes from the examination of genitourinary specimens removed during feminizing surgeries. Common benign changes associated with feminizing hormone therapy include the development of acini and lobules in the breast, testicular tubular changes, and squamous metaplasia of the prostate and urethra. Neoplastic cases include breast adenocarcinoma and fibroepithelial lesions, testicular germ cell tumors, prostatic adenocarcinoma, anal squamous cell carcinoma, pituitary adenomas, and meningiomas. Additional studies assessing the findings in other organ systems as well as population-based studies assessing rates of neoplasia are needed. However, future research relies on engagement within the surgical pathology community as well as collaboration with clinicians and patients to achieve optimal results.

Adolescent Transgender Females Present Impaired Semen Quality That Is Suitable for Intracytoplasmic Sperm Injection Even Before Initiating Gender-Affirming Hormone Treatment

The present study aimed to determine the semen quality and cryopreservation outcomes among adolescent transgender females at the time of fertility preservation (FP) before initiating gender-affirming hormone (GAH) treatment. This retrospective cohort study included 26 adolescent transgender females who underwent FP in our Fertility Institute between 06/2013 and 10/2020. Pre-freezing semen parameters were compared to WHO 2010 reference values. Post-thaw semen parameters were used to determine the adequate assisted reproductive technology (ART). A multivariate linear regression analysis was performed to assess the impact of medical and lifestyle factors on semen quality. The mean age at which adolescent transgender females underwent FP was 16.2 ± 1.38 years. The median values of all semen parameters in our study group were significantly lower compared to the WHO data, including volume (1.46 mL vs 3.2 mL, respectively, P = 0.001 ), sperm concentration (28 × 10⁶/mL vs 64 × 10⁶/mL, P < 0.001), total sperm number (28.2 × 10⁶ vs 196 × 10⁶, P < 0.001), total motility (51.6% vs 62%, P < 0.001), and normal morphology (2% vs 14%, P < 0.001). The frequency of semen abnormalities was teratozoospermia 72%, hypospermia 52%, oligozoospermia 28%, and azoospermia 4%. The median post-thaw total motile count was 0.17 × 10⁶/vial, and the quality was adequate only for ICSI in 87.7% of the thawed semen samples. No correlation was found between selected medical and lifestyle factors and poor semen parameters. Semen quality is strongly reduced among adolescent transgender females before hormone therapy and their stored sperm samples are suitable for intracytoplasmic sperm injection (ICSI) rather than conventional IVF/intrauterine insemination (IUI).

Contraception across transgender

Sexual and reproductive issues are essential elements of well-being in cisgenders as well as for the transgender population. Gender-affirming hormonal treatments (GAHTs) aim to induce phenotypical changes congruent with the desired gender and subsequent reduction of gender dysphoria. While genital surgical procedures including hysterectomy and/or adenectomy cause permanent loss of ability to conceive, GAHT may induce a varying degree of reversible loss of fertility. For these reasons, transgender men and women need to be counseled concerning contraceptive options and potential effects of treatment on reproductive function before initiating GAHT. The literature reports that sexual activity with genital involvement is performed by less than half of transgender persons who have been sexually active with a partner in the past. Testosterone (T) is the most commonly used compound in transmen and usually leads to amenorrhea within 1-12 months from first administration, however cessation of menses does not mean anovulation. Some studies report cases of unintended pregnancies among transgender men under masculinizing therapy, therefore T treatment cannot be considered a contraceptive option. Currently available contraceptive options have pros and cons in transmen and scarce literature exists on their use. The effects of GAHT on fertility in transwomen are even less well known. Prolonged estrogen exposure induces sperm suppression and morphological changes of the spermatozoa, however the degree of resulting pregnancy protection is unclear. Further research to inform the contraceptive counseling in this population is mandatory.

Attitudes Toward Fertility Preservation Among Transgender Youth and Their Parents

PURPOSE

While gender-affirming hormones (GAH) may impact the fertility of transgender and gender diverse (TGGD) youth, few pursue fertility preservation (FP). The objective of this study is to understand youth and parent attitudes toward FP decision-making.

METHODS

This study is a cross-sectional survey of youth and parents in a pediatric, hospital-based gender clinic from April to December 2017. Surveys were administered electronically, containing 34 items for youth and 31 items for parents regarding desire for biological children, willingness to delay GAH for FP, and factors influencing FP decisions.

RESULTS

The mean age of youth (n = 64) was 16.8 years, and 64% assigned female at birth; 46 parents participated. Few youth (20%) and parents (13%) found it important to have biological children or grandchildren, and 3% of youth and 33% of parents would be willing to delay GAH for FP. The most common factor influencing youth FP decision-making was discomfort with a body part they do not identify with (69%), and for the parents, whether it was important to their child (61%). In paired analyses, youth and their parents answered similarly regarding youth desire for biological children and willingness to delay GAH for FP.

CONCLUSIONS

The majority of TGGD youth and parents did not find having biological offspring important and were not willing to delay GAH for FP. Discomfort with reproductive anatomy was a major influencing factor for youth FP decision-making and their child's wishes was a major factor for parents. Future qualitative research is needed to understand TGGD youth and parent attitudes toward FP and to develop shared decision-making tools.

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.

Factors Affecting Fertility Decision-Making Among Transgender Adolescents and Young Adults

PURPOSE

This study aimed to identify factors affecting transgender adolescents' and young adults' (AYA) decisions to pursue fertility preservation (FP).

METHODS

Participants completed a semistructured interview between December 2016 and June 2017 to inform improvements in fertility counseling and the development of a fertility decision aid targeted to transgender youth. Interviews included open-ended questions within the following domains: (1) gender-affirming medical care received, (2) knowledge of gender-affirming hormone effects on fertility and FP options, (3) FP decision-making, and (4) how, when, and what information AYA prefer to receive regarding FP. The interviews were analyzed thematically.

RESULTS

Eighteen transgender AYA (ages 15-24) participated (60% participation rate). The majority was White (61%) and assigned female at birth (67%). Half received specialized FP counseling (50%). Few of the transgender AYA pursued FP (33%). Five key themes reflecting factors affecting transgender AYA's FP decision-making were identified: (1) future parenthood desires, (2) individual experiences of gender dysphoria, (3) family values around biological parenthood, (4) financial considerations, and (5) fertility information provision.

CONCLUSIONS

Transgender AYA consider numerous factors in deciding whether to pursue FP. Although individual desires for and family values around biological parenthood influenced whether AYA pursued specialized FP counseling, individual experiences of gender dysphoria and costs of FP were barriers. AYA also identified shortcomings in fertility counseling with providers, highlighting the need to establish standardized counseling protocols and develop patient decision aids.

Global changes in epigenomes during mouse spermatogenesis: possible relation to germ cell apoptosis

Mammalian spermatogenesis is characterized by disproportionate germ cell apoptosis. The high frequency of apoptosis is considered a safety mechanism that serves to avoid unfavorable transmission of paternal aberrant genetic information to the offspring as well as elimination mechanism for removal of overproduced immature or damaged spermatogenic cells. The molecular mechanisms involved in the induction of germ cell apoptosis include both intrinsic mitochondrial Bcl-2/Bax and extrinsic Fas/FasL pathways. However, little is known about the nuclear trigger of those systems. Recent studies indicate that epigenomes are essential in the regulation of gene expression through remodeling of the chromatin structure, and are genome-like transmission materials that reflect the effects of various environmental factors. In spermatogenesis, epigenetic errors can act as the trigger for elimination of germ cells with abnormal chromatin structure, abnormal gene expression and/or morphological defects (disordered differentiation). In this review, we focus on the relationship between global changes in epigenetic parameters and germ cell apoptosis in mice and other mammals.

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.

Fertility preservation rates among transgender women compared with transgender men receiving comprehensive fertility counselling

RESEARCH QUESTION

What is the fertility preservation rate among transgender women who have received professional fertility counselling compared with transgender men?

DESIGN

This retrospective cohort study included 56 transgender women and 56 transgender men referred for comprehensive fertility counselling at the Gender Clinic of the Tel Aviv Sourasky Medical Center's Fertility Institute between January 2017 and April 2019. Statistical analyses were performed to compare transgender men with transgender women who preserved fertility and transgender people who preserved fertility and those that did not.

RESULTS

The fertility preservation rate of transgender women was significantly higher than that of transgender men (85.7% versus 35.7%, respectively, P < 0.001). The fertility preservation rate among transgender women was associated with being older and not having undergone gender-affirming hormone (GAH) treatment. The fertility preservation rate was higher among adolescent transgender boys compared with adolescent transgender girls (35% versus 6.25%, respectively, P = 0.005). The duration of GAH treatment among the transgender men who preserved fertility was 70 months compared with 18.6 months for transgender women (P = 0.05). All transgender boys opted for oocyte cryopreservation, while half of the transgender men who had not started GAH opted for oocyte cryopreservation, and half of those who had already started on GAH opted for embryo cryopreservation.

CONCLUSIONS

High fertility preservation rates among transgender individuals were found after comprehensive fertility counselling. Fertility preservation rates among adults were higher among transgender women compared with transgender men, while the opposite was found in transgender adolescents.

Vascular and inflammatory effects of estrogen and anti-androgen therapy in the testis and epididymis of male to female transgender adults

The volume of ubiquitous chemicals with estrogenic properties is on the rise and some reports relate the increase in hormonal diseases to these compounds. A morphological and immunohistochemical analysis has been performed on 42 bilateral orchiectomy specimens from adult individuals who underwent gender reassignment surgery after receiving crossed-sex hormone therapy to give insight into vascular, inflammatory and epididymal changes following long-term treatment with estrogens and antiandrogens and raise awareness of the consequences of hormone therapy. The present study confirms previously reported findings in testicular parenchyma and epididymis, such as identification of three histological patterns according to lesion severity and cell dedifferentiation, and reports for the first time vascular and inflammatory lesions (atherosclerosis and vasculitis), both on testicle and epididymis. Cross-sex hormone therapy should be provided in specialized units in order to systematize treatments and ensure adequate follow-up.

Psychosocial challenges and hormonal treatment in gender diverse children and adolescents. A narrative review

Gender dysphoria (GD) in children and adolescents is a condition that is characterized by an incongruence between the assigned and experienced gender. Despite the diversity in clinical presentation, literature demonstrates that GD might lead to poor mental health and high rates of co-occurring psychopathology. Due to the overlap of physical aspects as well as psychological needs in these children, a multidisciplinary approach is highly desirable. The aim of this narrative review is to give an overview of recent literature on several topics relevant in this domain. Guidelines on psychological counseling and hormonal treatment are given and challenging topics subject to controversy are explained. Furthermore, attention is drawn to the risks and protective factors in psychological functioning, including the growing evidence of a frequent co-occurrence with Autism Spectrum Disorder. Finally the psycho-sexual development in these children, the impact on fertility and fertility preservation are discussed.

Spermatogonial Stem Cells in Fish: Characterization, Isolation, Enrichment, and Recent Advances of In Vitro Culture Systems

Spermatogenesis is a continuous and dynamic developmental process, in which a single diploid spermatogonial stem cell (SSC) proliferates and differentiates to form a mature spermatozoon. Herein, we summarize the accumulated knowledge of SSCs and their distribution in the testes of teleosts. We also reviewed the primary endocrine and paracrine influence on spermatogonium self-renewal vs. differentiation in fish. To provide insight into techniques and research related to SSCs, we review available protocols and advances in enriching undifferentiated spermatogonia based on their unique physiochemical and biochemical properties, such as size, density, and differential expression of specific surface markers. We summarize in vitro germ cell culture conditions developed to maintain proliferation and survival of spermatogonia in selected fish species. In traditional culture systems, sera and feeder cells were considered to be essential for SSC self-renewal, in contrast to recently developed systems with well-defined media and growth factors to induce either SSC self-renewal or differentiation in long-term cultures. The establishment of a germ cell culture contributes to efficient SSC propagation in rare, endangered, or commercially cultured fish species for use in biotechnological manipulation, such as cryopreservation and transplantation. Finally, we discuss organ culture and three-dimensional models for in vitro investigation of fish spermatogenesis.

[Preservation of fertility in transgender people]

Young transgender people increasingly seek medical help to assist them in their gender transition with hormone therapy and/or sex reassignment surgery. However, these treatments limit fertility and may make them irreversibly infertile. Studies show that the transgender population wishes to have biological children and, to help them achieve this desire for parenthood, there are techniques for preserving fertility, such as cryopreservation of gametes, embryos and ovarian or testicular tissue. However, alongside these techniques, there are ethical issues and several challenges before, during and after these procedures, that may lead young transgender people to reject these methods of preserving fertility. In conclusion, health professionals should be informed about all these dynamics between gender transition therapies and their impact on fertility, in order to better guide these individuals in their decision.

Fertility Preservation Outcomes in Adolescent and Young Adult Feminizing Transgender Patients

BACKGROUND

Fertility preservation enables patients undergoing gonadotoxic therapies to retain the potential for biological children and now has broader implications in the care of transgender individuals. Multiple medical societies recommend counseling on fertility preservation before initiating therapy for gender dysphoria; however, outcome data pre- and posttreatment are limited in feminizing transgender adolescents and young adults.

METHODS

The University of Pittsburgh Institutional Research Board approved this study. Data were collected retrospectively on transgender patients seeking fertility preservation between 2015 and 2018, including age at initial consultation and semen analysis parameters.

RESULTS

Eleven feminizing transgender patients accepted a referral for fertility preservation during this time; consultation occurred at median age 19 (range 16-24 years). Ten patients attempted and completed at least 1 semen collection. Eight patients cryopreserved semen before initiating treatment. Of those patients, all exhibited low morphology with otherwise normal median semen analysis parameters. In 1 patient who discontinued leuprolide acetate to attempt fertility preservation, transient azoospermia of 5 months' duration was demonstrated with subsequent recovery of spermatogenesis. In a patient who had previously been treated with spironolactone and estradiol, semen analysis revealed persistent azoospermia for the 4 months leading up to orchiectomy after discontinuation of both medications.

CONCLUSIONS

Semen cryopreservation is a viable method of fertility preservation in adolescent and young adult transgender individuals and can be considered in patients who have already initiated therapy for gender dysphoria. Further research is needed to determine the optimal length of time these therapies should be discontinued to facilitate successful semen cryopreservation.

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.

Fertility desires and reproductive needs of transgender people: Challenges and considerations for clinical practice

The majority of transgender and gender nonconforming persons seeking medical care are of reproductive age. Hormonal treatment and sex reassignment surgery, which are used in the management of gender dysphoria, compromise fertility potential. Children and adolescents with gender dysphoria have specific treatment regimens starting with puberty-blocking medications. According to international guidelines, fertility preservation should be discussed before any hormonal treatment, although our knowledge on the reproductive needs of transgender and gender nonconforming persons is limited. Recently, some data have emerged on fertility management in some centres for the adult population with gender dysphoria. The goal of this review was to summarize the available evidence on the fertility desires and parental roles of transgender and gender nonconforming people. In light of newly emerging societal challenges, we aim to provide some considerations for clinical practice and suggest further areas of research.

Fertility Considerations in Transgender Persons

Hormonal therapy and gender-affirming surgeries in transgender people have known deleterious impacts on future fertility using one's own gametes. This review focuses on fertility preservation, including the effects of medical hormone treatment on fertility, available and experimental options of fertility preservation in transgender adults, including sperm cryopreservation for transwomen and oocyte cryopreservation for transmen, and options for prepubertal transgender adolescents, including testicular and ovarian tissue cryopreservation. Transgender patients continue to face barriers and receive infrequent counseling regarding fertility preservation. Physicians should ideally counsel and discuss fertility preservation options before transgender patients undergo hormone therapy of gender-affirmation surgery.

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.

Knowledge, Practice Behaviors, and Perceived Barriers to Fertility Care Among Providers of Transgender Healthcare

PURPOSE

Transgender individuals may experience impaired fertility due to gender-affirming hormonal interventions (e.g., pubertal suppression treatment and/or exogenous hormones). Clinical practice guidelines recommend providers discuss fertility implications and options for fertility preservation. The goal of this study was to examine fertility knowledge, practice behaviors, and perceived barriers to fertility care among multidisciplinary providers who care for transgender pediatric and/or adult patients.

METHODS

A 46-item survey was distributed to relevant listservs and at conferences with a focus on transgender health.

RESULTS

Two hundred two providers completed the survey: (1) physicians (n = 87), (2) psychologists (n = 51), (3) Master (MA)-level mental health providers (n = 39), and (4) nonphysician healthcare providers, comprising advanced practice nurses, registered nurses, and physician assistants (n = 25). Overall knowledge was high (M = 3.64, SD = 1.61). Significant differences were identified in knowledge by provider type (p <.001) but not patient age group (p = .693). Physicians had significantly greater knowledge than MA-level mental health providers (p = .005). Variables associated with fertility discussion included provider-related barriers [b = -.42, p < .001], and perceived patient-related barriers, including perceptions that patients are unwilling to delay treatment [b = .12, p = .011] or are unable to afford fertility preservation (FP) [b = .12, p = .029].

CONCLUSIONS

While overall fertility-related knowledge was high, there was variability in domains of knowledge, as well as provider practice behaviors related to fertility counseling and referral for FP. Findings related to perceived barriers to fertility counseling and fertility preservation warrant further investigation; qualitative studies may be particularly helpful in understanding how specific provider- and patient-related barriers impact counseling and referral for fertility-related care.

The Reproductive Health Care of Transgender Young People: A Guide for Primary Care Providers

Primary care providers should have a general understanding of the medical care available to transgender youth throughout childhood and adolescence. Providers and parents should create an affirming environment for young people at every developmental stage, while ensuring thorough and thoughtful evaluations prior to any medical intervention. Transgender teens have unique reproductive health care needs. Transgender boys may seek suppression of menses, and they will need to pay particular attention to pregnancy prevention if they decide to undergo masculinizing hormonal treatment. Transgender girls who undergo feminizing hormonal treatment will also see profound changes to their reproductive and sexual function. Providers should feel comfortable getting detailed sexual histories to properly counsel on and test for sexually transmitted infections. Finally, the effects of medical and surgical transition on a young person's potential for future fertility is a profoundly important concept for both the teen and their parents to understand. [Pediatr Ann. 2019;48(2):e64-e70.].

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.

Attitudes Toward Fertility and Reproductive Health Among Transgender and Gender-Nonconforming Adolescents

PURPOSE

Little is known about the reproductive desires of transgender and gender-nonconforming (TGNC) adolescents who may seek gender-affirming medical care that leads to infertility. The current study addressed this gap by examining attitudes toward fertility and family formation in a diverse sample of TGNC youth.

METHOD

An online survey about sexual/reproductive health in sexual and gender minority (SGM) adolescents ages 14-17 years was conducted from September to October 2016.

RESULTS

A total of 156 TGNC adolescents (M_age = 16.1 years; 83.3% assigned female at birth; 58.3% youth of color) responded. Overall, 70.5% of TGNC adolescents were interested in adoption and 35.9% in biological parenthood; more gender-nonconforming youth (43.8%) than transgender youth (25.8%) expressed interest in biological fertility. Discussions with health-care providers about fertility and reproductive health were uncommon-only 20.5% of youth had discussed fertility in general and only 13.5% had discussed effects of hormones on fertility. However, 60.9% of respondents were interested in learning more about their fertility and family building options. Key themes emerging from qualitative comments included concerns related to fertility/reproductive health (e.g., stigma of SGM parenthood, effect of gender-affirming treatments on fertility), and the need for additional reproductive health information both tailored to their individual experience and for SGM individuals more generally.

DISCUSSION

TGNC adolescents expressed interest in multiple family building options, including adoption and biological parenthood, and identified a need for more information about these options. Thus, clinicians working with adolescents should be aware of the unique fertility and reproductive health needs of TGNC youth.

Spermatogenesis Abnormalities following Hormonal Therapy in Transwomen

Objective

To measure spermatogenesis abnormalities in transwomen at the time of sex reassignment surgery (SRS) and to analyze the association between hormonal therapy duration and infertility severity.

Design

Retrospective study.

Setting

University hospital.

Patients

One-hundred seventy-three transwomen who underwent SRS from January 2000 to December 2015.

Interventions

All orchidectomy specimens were retrospectively reviewed and classified. History of hormonal therapy duration was retrieved from medical records.

Main Outcome Measures

Histological examinations of orchidectomy specimens were performed to assess spermatogenesis.

Results

One-hundred seventy-three orchidectomy specimens were evaluated. Histological examinations showed maturation arrest in 36.4%, hypospermatogenesis in 26%, Sertoli cell-only syndrome in 20.2%, normal spermatogenesis in 11%, and seminiferous tubule hyalinization in 6.4% of the specimens. Spermatogenesis abnormality severity was not associated with the total therapy duration (P = 0.81) or patient age at the time of surgery (P = 0.88). Testicular volumes and sizes were associated with spermatogenesis abnormality severity (P = 0.001 and P = 0.026, right testicle and left testicle, resp.).

Conclusions

Feminizing hormonal treatment leads to reductions in testicular germ cell levels. All transwomen should be warned about this consequence, and gamete preservation should be offered before starting hormonal treatment.

Ethical Considerations in Fertility Preservation for Transgender Youth: A Case Illustration

Increasing numbers of transgender adolescents are presenting for transition-related medical care, including gender-affirming estrogen and testosterone. The decision to transition with hormones has long-term implications, including possible irreversible impairment of future reproductive functioning. The commentary by Hudson, Nahata, Dietz, and Quinn (2017) outlines the importance of fertility counseling for transgender adolescents and young adults as ethical, interdisciplinary practice. Key considerations raised include implementing shared decision-making strategies that account for youths' maturity and individual decisional capacity, evaluating co-occurring psychiatric conditions that could interfere with future-oriented decision-making, and considering benefits and harms of fertility preservation (FP) in the context of a youth's values, identity, and comfort. This report includes two case illustrations of transmasculine youth which highlight how ethical considerations emerge in clinical practice and underscore the nuance and complexity of fertility-related decision-making among transgender adolescents.

Advancing the Practice of Pediatric Psychology with Transgender Youth: State of the Science, Ongoing Controversies, and Future Directions

Growing numbers of transgender and gender-nonconforming (TGNC) youth are presenting for medical and mental health care, and increasingly, pediatric psychologists are being called upon to serve as critical members of interdisciplinary care teams. In this commentary, we present information on TGNC youth in three distinct developmental cohorts: prepubescent TGNC children, peripubertal TGNC youth, and pubertal TGNC adolescents. First, we describe the social, medical, and/or surgical treatments available to each cohort of youth. Next, we address the state of the science related to these treatments. Then, we highlight some of the ongoing controversies related to social, medical and/or surgical interventions that are most relevant to pediatric psychologists and the role they play in gender-affirming care. Finally, we conclude with a call for papers for an upcoming special issue of Clinical Practice in Pediatric Psychology focused on advancing the practice of pediatric psychology in transgender health care.
