Ethical considerations regarding penis transplantation surgery in transgender men-an empirical ethics study.

Background: The ongoing quest to surgically create the (nearly) ideal neophallus in transgender men has led to the continuous development of transgender medicine and the proposed introduction of penis transplantation. However, both technical and ethical issues arise when developing this treatment. Aim: We sought to extract ethical considerations among different stakeholder groups regarding penile transplantation surgery in transgender men and to define preliminary clinical recommendations. Methods: Three semistructured focus groups, consisting of different stakeholders, were organized to participate in discussions of ethical considerations retrieved from the ethics literature of transplantation and transgender medicine. Analysis of the results was performed according to empirical ethics. Outcomes: Study outcomes were the identification of qualitative themes describing ethical considerations pertaining to penile transplantation in transgender men. Results: Nineteen people participated in this qualitative study. The main domains that emerged included arguments in favor of and arguments against penile transplantation. Although the participants expressed positive attitudes toward developing this care, with acknowledgement of the current limitations stakeholders of all groups were reluctant to endorse the introduction of penile transplantation for transgender men at this point. Clinical Implications: Under the present circumstances, all groups expressed both a wide variety of ethical considerations as well as a tendency to prefer developing alternative treatment options or improving the results of currently available treatments in relation to penile transplantation for transgender men. Strengths and Limitations: This study was the first (empirical) study to focus on this topic and included a diversity of stakeholder perspectives. Limitations included the hypothetical nature of the discussion as well as the clinical setting in which the topic has been studied. Conclusion: Introducing penile transplantation for transgender men, under the current circumstances, comes with a wide range of ethical considerations, which deal with personal identity, autonomy, medical risks, risk for transgender support and donor willingness, and issues regarding equality. Despite the present hesitancy to use penile transplantation, should the technical side of this treatment option develop, further research in the ethical field of penile transplantation for transgender men is recommended.

HIV Prevalence and High-Risk Subgroup Identification in Transgender Women Who Undergo Primary Vaginoplasty in the Netherlands.

Purpose: Worldwide, transgender women (TGW) bear a high HIV burden. Limited data are available on HIV prevalence and risk factors among TGW in western European countries. Our aim is to assess the prevalence of TGW living with HIV who underwent primary vaginoplasty in an academic reference hospital and to identify high-risk subgroups. Methods: All TGW who underwent primary vaginoplasty between January 2000 and September 2019 at our institution were identified. A retrospective chart study was conducted, recording the medical history, age at vaginoplasty, region of birth, use of medication, injecting drug use, history of pubertal suppression, HIV status, and sexual preference at time of surgical intake. High-risk subgroups were identified using logistic regression analysis. Results: Between January 2000 and September 2019, a total of 950 TGW underwent primary vaginoplasty, of whom 31 (3.3%) individuals were known to live with HIV. Prevalence of HIV was higher in TGW born outside of Europe (20/145, 13.8%) than among those born in Europe (11/805, 1.4%), p<0.001. In addition, having a sexual preference toward men was significantly associated with HIV. None of the TGW living with HIV had a history of puberty suppression. Conclusion: The HIV prevalence in our study population is higher than the reported HIV prevalence in cisgender population in the Netherlands but lower than reported in previous studies in TGW. Further studies should investigate the need and feasibility of routine HIV testing of TGW in Western countries.

Triangular Flap Extension to Create a Meatal Appearance in Phalloplasty Without Urethral Lengthening.

OBJECTIVE: To describe an easy-to-perform surgical refinement to create a meatal appearance in phalloplasty without urethral lengthening by using a triangular flap extension. METHODS: Transgender men undergoing phalloplasty without urethral lengthening are candidate for this flap extension. A triangular flap is drawn at the distal part of the flap. When the flap is raised, this triangle is raised with the flap and subsequently folded in the tip of the neophallus, thus creating a neomeatal appearance. RESULTS: We present this easy-to-perform technique, our experience and postoperative results. Two pitfalls of this technique are: (1) when it is insufficiently trimmed and thinned, it adds too much bulk to the phallic top and (2) when it is insufficiently vascularized, wound healing problems will occur; especially since the neophallus will swell in the immediate postoperative phase. CONCLUSION: Using a triangular flap extension is an easy method to create a neomeatal appearance.

How Sensitive Is the Neophallus? Postphalloplasty Experienced and Objective Sensitivity in Transmasculine Persons.

INTRODUCTION: Tactile and erogenous sensitivity of the neophallus after phalloplasty is assumed to affect the sexual well-being of transmasculine persons and, ultimately, their quality of life. The experienced and objective sensation of the neophallus and their association are largely unknown. AIM: This study evaluated experienced tactile and erotic sensation of the neophallus in transmasculine persons and investigated how this was related to objective tactile sensitivity. METHODS: Between August 2017 and January 2020, 59 transmasculine persons who underwent phalloplasty were recruited to participate in a prospective follow-up study. Tactile sensitivity of the neophallus and donor-site was measured (Semmes-Weinstein Monofilament test) and compared, and participants were asked to fill out a questionnaire about experienced sensation of the neophallus and sexual wellbeing. MAIN OUTCOME MEASURES: Experienced and objective sensation of the neophallus were measured by using a questionnaire and Semmes-Weinstein Monofilament scores. RESULTS: Neophallic tactile sensitivity was significantly reduced compared to the donor-site (n = 44), with the proximal part being more sensitive than the distal part (median follow-up of 1.8 years, range 1.0-7.2)). Sensitivity of the neophallus was not significantly associated with the surgical flap used, yet increased significantly with follow-up time. The questionnaire was completed by 26 participants of which 24 (92.3%) experienced (some degree of) tactile sensitivity in their neophallus. Erogenous sensation was experienced by 23 (88.5%). Experienced and objectified tactile sensitivity were not significantly correlated (Spearmans's rho = 0.23, P = .26). Answers to open-ended questions showed that results often do not match expectations. CONCLUSION: Tactile sensation of the neophallus was reduced in most transmasculine persons and improved slowly over time. A significant association between subjective and objective measures could not be detected. Although experienced sensitivity varied between individuals, the vast majority reported to have tactile and erotic sensitivity in the neophallus.Transmasculine persons should be informed that sensitivity of the neophallus will likely be reduced.

Gender-Confirming Vulvoplasty in Transgender Women in the Netherlands: Incidence, Motivation Analysis, and Surgical Outcomes.

BACKGROUND: Penile inversion vaginoplasty is the surgical gold standard for genital gender-affirmative surgery in transgender women. However, there is an increase of attention for gender-confirming vulvoplasty (GCV), in which no neovaginal cavity is created. AIM: To describe underlying motives and surgical outcomes of GCV in transgender women. METHODS: All transgender women who underwent GCV were retrospectively identified from a departmental database. A retrospective chart study was conducted, recording underlying motives, demographics, perioperative complications, and reoperations. OUTCOMES: Underlying motives and perioperative complication rate. RESULTS: In the period January 1990 to January 2020, 17 transgender women underwent GCV at our center. Most women reported that their motivation to undergo GCV was because they had no wish for postoperative neovaginal penetration (n = 10, 59%). This was due to a sexual preference toward women without the wish for neovaginal penetrative intercourse (n = 6, 35%) or due to a negative sexual experience in the past (n = 4, 24%). Some women desired vaginoplasty with neovaginal cavity creation but were ineligible for this because of their medical history (n = 4, 24%), for example, due to locoregional radiotherapy. The median clinical follow-up was 34 months (range 3-190). The postoperative course was uncomplicated in 11 (65%) women. Postoperative complications comprised the following: meatal stenosis (n = 2, for which surgical correction), remnant corpus spongiosum tissue (n = 1, for which surgical correction), minor wound dehiscence (n = 3, for which conservative management), and postoperative urinary tract infection (n = 1, successfully treated with oral antibiotics). One woman, who developed meatal stenosis, had a history of radiotherapy because of rectal carcinoma and needed 2 surgical procedures under general anesthesia to correct this. Information on self-reported satisfaction was available for 12 women. All were satisfied with the postoperative result and they graded their neovagina an 8.2 ± 0.9 out of 10. CLINICAL IMPLICATIONS: GCV may be added to the surgical repertoire of the gender surgeon. Transgender women with a desire for genital gender-affirmative surgery should be counseled on surgical options and its (dis)advantages. STRENGTHS & LIMITATIONS: Strengths of this study comprise that it is from a high-volume center. A weakness of this study is the retrospective design. The absence of a self-reported outcome measure validated for the transgender persons is a well-known problem. CONCLUSION: An increase is observed in transgender women who opt for GCV; however, the absolute number undergoing this surgery remains small in our center. Postoperative complications do occur but are generally minor and treatable. van der Sluis WB, Steensma TD, Timmermans FW, et al.

The First Experience of Using the Pedicled Labia Minora Flap for Urethral Lengthening in Transgender Men Undergoing Anterolateral Thigh and Superficial Circumflex Iliac Artery Perforator Flap Phalloplasty: A Multicenter Study on Clinical Outcomes.

OBJECTIVE: To describe the novel surgical technique of urethral lengthening in anterolateral thigh and superficial circumflex iliac artery perforator flap phalloplasty with a pedicled labia minora flap (PLMF) and report on the clinical outcomes. METHODS: Between March 2014 and August 2018, 16 transgender men underwent phalloplasty with a PLMF for urethral lengthening at the Amsterdam UMC (VU university), the Netherlands and the Belgrade University Hospital, Serbia. Patient demographics, surgical characteristics, neourethra characteristics, intra- and postoperative complications, pre-and postoperative voiding evaluation, and the length of hospital stay were retrospectively identified from chart reviews. RESULTS: The mean neourethral length was 16.8 ± 2.3 cm, and the pars pendulans 11.7 ± 2.2 cm. The neomeatus was localized on top of the neophallus in 12 (75%) patients. No intraoperative complications occurred. Urethral fistula formation occurred in 4 (25%) patients and strictures in 6 (37.5%) patients. In 3 (18.7%) patients a (temporary) perineostomy had to be performed. Voiding from a standing position was possible in 9 (56.3%) patients. CONCLUSION: The PLMF for urethral reconstruction, both pars fixa and pars pendulans, in phalloplasty is a feasible surgical technique in transgender men undergoing anterolateral thigh or superficial circumflex iliac artery perforator flap phalloplasty with sufficient labia minora tissue.

Genital Gender-Affirming Surgery in Transgender Men in The Netherlands from 1989 to 2018: The Evolution of Surgical Care.

BACKGROUND: The number of individuals with gender identity incongruence seeking treatment, including genital gender-affirming surgery, has increased over the past decade. Surgical techniques for genital gender-affirming surgery in transgender men have evolved considerably. The aim of this study was to present an overview of the evolution of genital gender-affirming surgery for transgender men in a single, high-volume center. METHODS: The authors performed a retrospective analysis of medical records of all transgender men who underwent genital gender-affirming surgery from January of 1989 to January of 2018 at their institution. Subject demographics, type of surgery, and surgical techniques were recorded. RESULTS: Over time, four hundred transgender men underwent genital gender-affirming surgery. Metoidioplasty was performed in 222 patients (56 percent) and phalloplasty in 178 patients (44 percent). Before 2010, the majority of patients underwent metoidioplasty, whereas since 2010, phalloplasty has been performed in most patients. Of 400 patients, 332 (83 percent) underwent urethral lengthening. The option to undergo genital surgery without urethral lengthening was offered from 2004. Since then, 68 (34 percent) patients chose to undergo genital gender-affirming surgery without urethral lengthening. The choice of surgical options for genital gender-affirming surgery in transgender men has grown from five in 1989 to 12 techniques currently. The variety and combination of flaps used for phalloplasty has increased over time. Conversely, the use of some flaps has been abandoned, whereas other flaps have reemerged. CONCLUSIONS: Genital gender-affirming surgery has developed over time in line with reconstructive surgical innovations. Despite technical advancements, there is no one ideal technique, and every technique has specific advantages and disadvantages. With the increase in surgical options, shared decision-making and a shift from surgeon-centered toward more patient-centered care are required.

The Surgical Techniques and Outcomes of Secondary Phalloplasty After Metoidioplasty in Transgender Men: An International, Multi-Center Case Series.

INTRODUCTION: Some transgender men express the wish to undergo genital gender-affirming surgery. Metoidioplasty and phalloplasty are procedures that are performed to construct a neophallus. Genital gender-affirming surgery contributes to physical well-being, but dissatisfaction with the surgical results may occur. Disadvantages of metoidioplasty are the relatively small neophallus, the inability to have penetrative sex, and often difficulty with voiding while standing. Therefore, some transgender men opt to undergo a secondary phalloplasty after metoidioplasty. Literature on secondary phalloplasty is scarce. AIM: Explore the reasons for secondary phalloplasty, describe the surgical techniques, and report on the clinical outcomes. METHODS: Transgender men who underwent secondary phalloplasty after metoidioplasty were retrospectively identified in 8 gender surgery clinics (Amsterdam, Belgrade, Bordeaux, Austin, Ghent, Helsinki, Miami, and Montreal). Preoperative consultation, patient motivation for secondary phalloplasty, surgical technique, perioperative characteristics, complications, and clinical outcomes were recorded. MAIN OUTCOME MEASURE: The main outcome measures were surgical techniques, patient motivation, and outcomes of secondary phalloplasty after metoidioplasty in transgender men. RESULTS: Eighty-three patients were identified. The median follow-up was 7.5 years (range 0.8-39). Indicated reasons to undergo secondary phalloplasty were to have a larger phallus (n = 32; 38.6%), to be able to have penetrative sexual intercourse (n = 25; 30.1%), have had metoidioplasty performed as a first step toward phalloplasty (n = 17; 20.5%), and to void while standing (n = 15; 18.1%). Each center had preferential techniques for phalloplasty. A wide variety of surgical techniques were used to perform secondary phalloplasty. Intraoperative complications (revision of microvascular anastomosis) occurred in 3 patients (5.5%) undergoing free flap phalloplasty. Total flap failure occurred in 1 patient (1.2%). Urethral fistulas occurred in 23 patients (30.3%) and strictures in 27 patients (35.6%). CLINICAL IMPLICATIONS: A secondary phalloplasty is a suitable option for patients who previously underwent metoidioplasty. STRENGTHS & LIMITATIONS: This is the first study to report on secondary phalloplasty in collaboration with 8 specialized gender clinics. The main limitation was the retrospective design. CONCLUSION: In high-volume centers specialized in gender affirming surgery, a secondary phalloplasty in transgender men can be performed after metoidioplasty with complication rates similar to primary phalloplasty.

A Retrospective Cohort Study on Surgical Outcomes of Penile Prosthesis Implantation Surgery in Transgender Men After Phalloplasty.

OBJECTIVES: To assess surgical outcomes of penile prosthesis implantation in transgender men who underwent phalloplasty. PATIENTS AND METHODS: Transgender men who underwent penile prosthesis implantation after phalloplasty between January 1989 and September 2018 were retrospectively identified. A chart study was performed recording patient demographics, perioperative complications, and reoperations. RESULTS: A total of 32 patients were identified: 22 underwent free radial forearm flap, 5 anterolateral thigh, 4 anterolateral thigh/free radial forearm flap, and 1 fibular flap phalloplasty. The median age at prosthesis implantation was 36 (range 21-59) years, the mean BMI 25.9 ± 4.0 kg/m2. At first implantation, 16 inflatable (AMS Dynaflex (n = 13), AMS Ambicor (n = 3)) and 16 malleable (Coloplast genesis (n = 14), AMS Spectra (n = 2)) prostheses were placed. Of these, 5 (16%) were removed/replaced because of infection, 2 (6%) because of leakage, 2 because of extrusion, 2 because of dislocation, 2 because of dysfunction, and 1 (3%) because of pain. The postoperative course was completely uneventful in 10 (31.3%) patients. Of all implanted prostheses, including revision procedures (n = 45), 21 (44%) were surgically replaced or removed. CONCLUSION: Prosthesis explantation, replacement, or revision surgery occurs frequently after penile prosthesis implantation. Patients need to be well-informed preoperatively on these complication rates.

Symptomatic Neovaginal Candidiasis in Transgender Women After Penile Inversion Vaginoplasty: A Clinical Case Series of Five Consecutive Patients.

Background: Vaginoplasty is performed as gender-affirming surgery in transgender women. While multiple surgical techniques exist for this goal, penile inversion vaginoplasty is performed most frequently. Neovaginal symptoms may impede sexual functioning after surgery. Methods: A total of five consecutive patients with symptoms and positive swabs for neovaginal candida infection were described. Results: All patients presented with white-colored neovaginal discharge and some with neovaginal itching and/or malodor. All were topically treated with miconazole, which resulted in symptom clearance. Follow-up swabs were negative for candida. Conclusions: To our knowledge, this is the first report on (symptomatic) candidiasis of the penile-inverted neovagina.

Dorsal fracture-dislocations of the proximal interphalangeal joint: evaluation of closed reduction and percutaneous Kirschner wire pinning.

BACKGROUND: The purpose of this study is to evaluate the outcome of closed reduction and percutaneous Kirschner wire pinning in acute dorsal fracture-dislocations of the proximal interphalangeal (PIP) joint. METHODS: Eight men and one woman were treated with closed reduction and percutaneous Kirschner wire pinning by one orthopaedic surgeon. The ring finger was injured in six patients, the small finger in two patients and the middle finger in one patient. The mean joint surface involvement was 36 % (range, 26-49 %). The Kirschner wires were removed after an average of 28 days (range, 24-37 days). RESULTS: All patients demonstrated a painless, but fusiform, swollen PIP joint after a mean follow-up of 6.5 months. The average flexion of the PIP joint was 106° (range, 80-110), and the average extension of the PIP joint was 4° short of full extension (range, 10 hyperextension-15 flexion contracture). All patients had a concentrically reduced PIP joint with a healed fracture on radiographs. Two patients had radiographic evidence of degenerative changes, but were asymptomatic. One patient developed a superficial pin track infection, which quickly resolved with a short course of antibiotics, and avascular necrosis affecting one of the condyles of the proximal phalanx. CONCLUSIONS: In agreement with previous studies, closed reduction and percutaneous Kirschner wire pinning in dorsal fracture-dislocations of the PIP joint is a minimally invasive and simple technique which appears to give satisfactory outcomes in the short to intermediate term.

Influence of intraocular pressure on retinal vascular caliber measurements in children.

PURPOSE: To determine whether intraocular pressure (IOP) influences retinal vascular caliber in young children, in order to provide a better understanding of its physiological determinants. DESIGN: Cross-sectional study. METHODS: Three hundred and eighty-six Chinese children seven to nine years of age participated in the Singapore Cohort Study of the Risk factors for Myopia (SCORM). IOP was measured by noncontact tonometry. Retinal vascular calibers were measured from retinal photographs using a computer-based program following standardized protocols. RESULTS: After adjusting for age, gender, body mass index, corneal thickness, spherical equivalent refraction, axial length, and birth weight, mean retinal arteriolar and venular caliber were similar across the distribution of IOP (arteriolar caliber of 155.2 microm, 155.6 microm, 153.8 microm, 154.2 microm, P value for trends, 0.45; and venular caliber of 225.7 microm, 220.6 microm, 224.5 microm, 222.7 microm, P value for trends, 0.53; comparing increasing quartiles of IOP). CONCLUSIONS: Our study provides no evidence that IOP influences retinal vascular caliber in healthy young children.

Blood pressure and retinal arteriolar narrowing in children.

Retinal arteriolar narrowing is a known response of hypertension and independently predicts cardiovascular mortality in adults. Whether elevated blood pressure leads to retinal arteriolar narrowing in young children is unknown. We examined the relationship of retinal vascular caliber and blood pressure levels in 2 population-based cohorts among children aged 6 to 8 years in Sydney, Australia (1572 children) and Singapore (380 children). Participants had digital retinal photographs and measurement of retinal arteriolar (or small artery) and venular (or small vein) caliber. Children with higher quartiles of blood pressure had significantly narrower retinal arterioles than those with lower blood pressure (retinal arteriolar caliber 162.8, 161.0, 157.8, and 157.1 microm (P for trend<0.001), comparing increasing quartiles of systolic blood pressure in Sydney, and 164.9.5, 164.0, 159.1, and 159.4 microm (P for trend=0.0024 in Singapore). After controlling for age, sex, race, body mass index, refraction, and birth parameters, each 10-mm Hg increase in systolic blood pressure was associated with narrowing of the retinal arterioles by 2.08 microm (95% confidence interval: 1.38 to 2.79; P<0.0001) in Sydney children and 1.43 microm (95% confidence interval: 0.27 to 2.59; P=0.016) in Singapore children. These associations were consistent across age, sex, body mass index, and birth parameters. Retinal venules were not affected by blood pressure. We conclude that higher childhood blood pressure is associated with retinal arteriolar narrowing. Our data provide evidence that the effects of elevated blood pressure may manifest early in life.

Distribution and associations of retinal vascular caliber with ethnicity, gender, and birth parameters in young children.

PURPOSE: To describe the distribution of retinal vascular calibers and their associations with ethnicity, gender, and birth parameters in children. METHODS: This was a school-based cross-sectional study of 768 children aged 7 to 9 years who participated in the Singapore Cohort Study of the Risk Factors for Myopia (SCORM). Participants had retinal photographs taken in 2001. Retinal vascular calibers were measured with computer-based program and summarized as average caliber of arterioles and venules in that eye. Associations of retinal vascular caliber with ethnicity, gender, and various birth factors were analyzed. RESULTS: In this population, the mean retinal arteriolar caliber was 156.4 microm (95% confidence interval [CI], 155.4-157.3) and venular caliber was 225.4 microm (95% CI, 224.1-226.8). The retinal arteriolar caliber was significantly narrower in Chinese (154.9 microm), compared with Malay (158.6 microm) and Indian (158.5 microm) children. Retinal venular caliber was also narrower in Chinese (223.3 microm) compared with Malay (230.8 microm) and Indian (229.0 microm) children. These differences were statistically significant, even after adjustments for age, gender, family income, parental education, body mass index, height, birth weight, axial length, and spherical equivalent (P = 0.05 for arteriolar caliber; P = 0.002 for venular caliber). In multivariate analysis, there were no significant gender differences in retinal vascular caliber. Birth factors, including birth weight, birth length, head circumference, and gestational age, were not significantly associated with changes in either retinal arteriolar or venular caliber. CONCLUSIONS: The results show ethnic variation in retinal vascular caliber in Singaporean children. No association of birth parameters with retinal vascular caliber was found. Because retinal vascular caliber is related to various cardiovascular and ocular diseases, it is possible that ethnic variations in retinal vascular caliber should be taken into consideration in future studies.

BMI and retinal vascular caliber in children.

OBJECTIVE: In adult populations, changes in retinal vascular caliber have been linked with obesity and metabolic syndrome. We examined the association of BMI and weight with retinal vascular caliber in children. RESEARCH METHODS AND PROCEDURES: This was a school-based, cross-sectional study of 768 children, 7 to 9 years old, randomly sampled from the Singapore Cohort Study of the Risk Factors for Myopia. Participants had digital retinal photographs. Retinal vascular caliber was measured using a computer-based program and combined to provide average calibers of arterioles and venules in that eye. Weight and height were measured using standardized protocol. These data were used to calculate BMI. RESULTS: In this population, the mean retinal arteriolar and venular calibers were 156.40 microm [95% confidence interval (CI), 155.44 to 157.36] and 225.43 microm (95% CI, 224.10 to 226.74) respectively. After controlling for age, gender, race, parental monthly income, axial length, birth weight, and birth length, each 3.1 kg/m2 (standard deviation) increase in BMI was associated with a 2.55-microm (95% CI, 1.21 to 3.89; p < 0.001) larger retinal venular caliber. In multivariable analysis, greater weight was also significantly associated with larger retinal venular caliber. BMI and weight were not associated with retinal arteriolar caliber. Height was not significantly associated with retinal arteriolar or venular caliber. DISCUSSION: Greater BMI and weight are associated with larger retinal venular caliber in healthy children.
