Andrology of male-to-female transsexuals: influence of cross-sex hormone therapy on testicular function

Fertility concerns of the transgender patient

Transgender individuals who undergo gender-affirming medical or surgical therapies are at risk for infertility. Suppression of puberty with gonadotropin-releasing hormone agonist analogs (GnRHa) in the pediatric transgender patient can pause the maturation of germ cells, and thus, affect fertility potential. Testosterone therapy in transgender men can suppress ovulation and alter ovarian histology, while estrogen therapy in transgender women can lead to impaired spermatogenesis and testicular atrophy. The effect of hormone therapy on fertility is potentially reversible, but the extent is unclear. Gender-affirming surgery (GAS) that includes hysterectomy and oophorectomy in transmen or orchiectomy in transwomen results in permanent sterility. It is recommended that clinicians counsel transgender patients on fertility preservation (FP) options prior to initiation of gender-affirming therapy. Transmen can choose to undergo cryopreservation of oocytes or embryos, which requires hormonal stimulation for egg retrieval. Uterus preservation allows transmen to gestate if desired. For transwomen, the option for FP is cryopreservation of sperm either through masturbation or testicular sperm extraction. Experimental and future options may include cryopreservation and in vitro maturation of ovarian or testicular tissue, which could provide prepubertal transgender youth an option for FP since they lack mature gametes. Successful uterus transplantation with subsequent live birth is a new medical breakthrough for cisgender women with uterus factor infertility. Although it has not yet been performed in transgender women, uterus transplantation is a potential solution for those who wish to get pregnant. The transgender population faces many barriers to care, such as provider discrimination, lack of information, legal barriers, scarcity of fertility centers, financial burden, and emotional cost. Further research is necessary to investigate the feasibility of experimental FP options, provide better evidence-based information to clinicians and transgender patients alike, and to improve access to and quality of reproductive services for the transgender population.

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.

Health care provider perceptions of fertility preservation barriers and challenges with transgender patients and families: qualitative responses to an international survey

PURPOSE

To examine provider perceptions of practice behaviors and barriers related to fertility counseling, fertility preservation, and family building among transgender patients.

METHODS

Participants were medical and mental health professionals who treat adult and youth transgender patients. Recruitment occurred online and in person, via professional listservs for transgender professionals, conferences, and gender clinics. From August-November 2017, 110 participants representing nine countries responded to four open-ended questions included on a survey related to provider practice behaviors and perceived barriers to fertility counseling, fertility preservation, and family building with transgender patients. Thematic coding analysis was used to identify themes.

RESULTS

Multiple themes were identified including the following: access and cost issues; urgency for gender-affirming treatment; patient maturity and inability to make future-oriented decisions; and provider-related challenges pertaining to knowledge, role, and general lack of information in the nascent field of transgender reproductive health.

CONCLUSION(S)

This study yielded insights into practice behaviors, challenges, and perceived barriers to fertility counseling with transgender individuals and can serve as a basis for intervention development to optimize clinical practices with this population.

Optimizing HIV prevention and care for transgender adults

: Transgender women have recently been acknowledged as a unique and important risk group in HIV research and care. Although transgender men also face specific problems related to HIV infection, less is known about the risk behaviours and HIV prevalence of this important population. This article highlights key issues relating to the epidemiology, prevention, treatment and management of complications of HIV infection in transgender adults living with HIV, and explores future areas for HIV-related research, with the ultimate goal of improving healthcare provision and quality of life for transgender persons worldwide.

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.
