The Comparison of Gender Dysphoria, Body Image Satisfaction and Quality of Life Between Treatment-Naive Transgender Males With and Without Polycystic Ovary Syndrome.

The prevalence of polycystic ovary syndrome (PCOS) among trans men has been reported as higher than among the cisgender population, which varies between 14.4% and 58%. In this cross-sectional study, we aimed to evaluate the association of oligo-anovulation and/or features of hyperandrogenism with the scores on the Utrecht Gender Dysphoria Scale (UGDS), the Body Image Scale (BIS), and the Short Form-36 Health Survey (SF-36) in treatment-naive trans men with PCOS seeking help for gender transition. The study sample consisted of trans men who were diagnosed with gender dysphoria (GD) between December 2019 and November 2020. To assess body dissatisfaction and psychological functioning, the UGDS, BIS, and SF-36 were administered to all transgender individuals as part of the routine assessment procedure. A total of 49 treatment-naive trans men were included in our study; 38.8% (n=19) of the participants were diagnosed with PCOS using the Rotterdam 2003 criteria. The scores of UGDS and BIS were significantly lower in the PCOS group compared with the non-PCOS group (p<0.001 and p=0.003, respectively). Among the eight parameters within SF-36, general health, emotional role, and vitality scores were significantly higher in the PCOS group (p=0.031, p=0.015, and p=0.006, respectively). Our study is the first study that demonstrates significantly lower GD, higher body image satisfaction and quality of life in trans men with PCOS compared with those without PCOS. Our findings are promising for larger prospective cohort studies to develop a consensus on the management of PCOS in trans men.

Integrating transwomen athletes into elite competition: The case of elite archery and shooting.

The inclusion of transwomen into elite female sport has been brought into question recently with World Rugby banning transwomen from the elite female competition, aiming to prioritise safety over fairness and inclusion, citing the size, force and power-producing advantages conferred to transwomen. The same question is being asked of all Olympic sports including non-contact sports such as archery and shooting. As both these Olympic sports are the polar opposite to the contact sport of rugby in terms of the need to consider the safety of athletes, the IF of both archery and shooting should consider the other elements when deciding the integration of trans individuals in their sports. Studies on non-athletic transwomen have reported muscle mass and strength loss in the range of 5-10% after 1 year of their transition, with these differences no longer apparent after 2 years. Therefore, based on the current scientific literature, it would be justified for meaningful competition and to prioritise fairness, that transwomen be permitted to compete in elite archery after 2 years of GAT. Similarly, it would be justified in terms of shooting to prioritise inclusion and allow transwomen after 1 year of GAT given that the only negligible advantage that transwomen may have is superior visuospatial coordination. The impact of this considered integration of transwomen in elite sports such as archery and shooting could be monitored and lessons learned for other sports, especially where there are no safety concerns from contact with an opponent.

Integrating Transwomen and Female Athletes with Differences of Sex Development (DSD) into Elite Competition: The FIMS 2021 Consensus Statement.

Sport is historically designated by the binary categorization of male and female that conflicts with modern society. Sport's governing bodies should consider reviewing rules determining the eligibility of athletes in the female category as there may be lasting advantages of previously high testosterone concentrations for transwomen athletes and currently high testosterone concentrations in differences in sex development (DSD) athletes. The use of serum testosterone concentrations to regulate the inclusion of such athletes into the elite female category is currently the objective biomarker that is supported by most available scientific literature, but it has limitations due to the lack of sports performance data before, during or after testosterone suppression. Innovative research studies are needed to identify other biomarkers of testosterone sensitivity/responsiveness, including molecular tools to determine the functional status of androgen receptors. The scientific community also needs to conduct longitudinal studies with specific control groups to generate the biological and sports performance data for individual sports to inform the fair inclusion or exclusion of these athletes. Eligibility of each athlete to a sport-specific policy needs to be based on peer-reviewed scientific evidence made available to policymakers from all scientific communities. However, even the most evidence-based regulations are unlikely to eliminate all differences in performance between cisgender women with and without DSD and transwomen athletes. Any remaining advantage held by transwomen or DSD women could be considered as part of the athlete's unique makeup.

Cardiovascular disease in transgendered people: A review of the literature and discussion of risk.

This review examines the impact of gender affirming hormone therapy used in the transgendered and non-binary populations on cardiovascular outcomes and surrogate markers of cardiovascular health. Current evidence suggests that hormonal therapy for transgendered women decreases or is neutral regarding myocardial infarction risk. There is an increased incidence of venous thromboembolism (VTE), but newer studies suggest that the risk is significantly lower than previously described. For transgendered men, there appears to be an adverse effect on lipid parameters but this does not translate into an increased risk of cardiovascular disease above that of general male population. In all transgendered people, risk factor interventions such as smoking cessation, weight management and treatment of co-morbid conditions are important in optimising cardiovascular health. The effect of gender affirming hormonal therapy in transgendered people is difficult to interpret due to the variety of hormone regimens used, the relative brevity of the periods of observation and the influence of confounding factors such as the historical use of less physiological, oestrogens such as conjugated equine oestrogen and ethinylestradiol which are more pro-thrombotic than the 17ß oestradiol that is used in modern practice.

The Fluidity of Gender and Implications for the Biology of Inclusion for Transgender and Intersex Athletes.

One of the most contentious issues in modern day sport arises when sports are divided into male and female categories. The International Association of Athletics Federations' (IAAF) previous policy regulating intersex athletes was suspended by the Court of Arbitration for Sport (CAS), resulting in a new policy. The challenge faced by the governing body of athletics is to formulate a policy that upholds both international law and the Olympic charter that stipulates athletes compete without discrimination of any kind. Implementation of the policy has been delayed until after a verdict, expected no later than March 26, 2019, in the Semenya versus IAAF trial in the Court of Arbitration for Sport. If the policy is enacted, it will restrict athletes from competing in the female athletics category with specific differences of sex development (DSD) in races from 400 m up to the mile in international level competitions unless they lower their natural testosterone (T) levels below 5 nmol·L. To thoroughly assess this new IAAF policy, one needs to appreciate its legal, sociological, and scientific underpinnings but also the history of previous policies attempting to define precisely how athletes should be divided into male and female categories. We previously proposed a system to deal with gender variant athletes that relied on a determination of an "athlete/athletic gender." The concept of "athlete gender" was presented to multiple audiences, and the resulting survey is included. A large majority of participants (71% of 153) who answered the survey agreed with the idea of an athlete gender. This position also was accompanied by the request for more studies (20% of those who agreed) and concern over the process of hormone monitoring (32% of those who agreed) to avoid doping misuse. The primary argument of those participating in the survey that disagreed with the position (23% of 153) was that biological differences between males and females remained even after the transition (47% of opposing comments). Mixed gender/sex competitions provide unique opportunities for athletes to compete against one another outside of the traditional male/female divide and pave the way for a more flexible approach for dealing with gender variant athletes.

Non-binary or genderqueer genders.

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

A review of the physical and metabolic effects of cross-sex hormonal therapy in the treatment of gender dysphoria.

This review focuses on the effect that cross-gender sex steroid therapy has on metabolic and hormonal parameters. There is an emphasis on those changes that result in significant clinical effects such as the positive effects of the development of secondary sexual characteristics and negative effects such as haemostatic effects and thromboembolism in transwomen or dyslipidaemia in transmen. There is also a description of the current hormonal regimens used at the largest UK gender identity clinic. The overall safety of these treatments in the context of long-term outcome data is reviewed.

Kallmann syndrome patient with gender dysphoria, multiple sclerosis, and thrombophilia.

One of the challenging issues in patients with complex problems is that the various diseases and their treatment can influence each other and present unusual hurdles in management. We investigated one such complex case. A 34-year-old XY male presented with azoospermia, detected on semen analysis for pre-orchidectomy sperm banking. He had a 20-year history of gender dysphoria and bilateral breast swelling. The patient suffered a deep vein thrombosis at the age of 19 years. Examination confirmed clinical features of Kallmann syndrome including unilateral cryptorchidism, micropenis, congenital anosmia, and bimanual synkinesis (mirror movements), with reduced serum testosterone and normal gonadotropin levels demonstrating hypogonadotropic hypogonadism. MRI showed missing olfactory bulbs. Osteopenia and reduced vitamin D levels of 21 nmol/L were identified. He was found to harbor a heterozygous factor-V-Leiden mutation. The genetic basis of Kallmann syndrome remains unknown: his screening tests were negative for mutations in CHD7, FGF8, FGFR1, GNRH1, GNRHR, HS6ST1, KAL1, KISS1R, KISS1, NELF, PROK2, PROKR2, TAC3, and TACR3. The patient initially declined testosterone therapy with a view to undergo gender reassignment. Over the next 2 years, the patient experienced recurrent episodes of weakness and paresthesia, associated with classical MRI appearances of multiple sclerosis-related demyelination in the spinal cord and brain. Although it was difficult to elucidate an association between the patient's gender dysphoria and untreated congenital hypogonadism, his desire to become female together with his co-existing thrombophilia, presented challenges to the administration of hormone treatment. Furthermore, we have considered an association between multiple sclerosis and hypogonadotropic hypogonadism.

Identification of hypothalamic nuclei involved in the orexigenic effect of melanin-concentrating hormone.

The hypothalamic neuropeptide melanin-concentrating hormone (MCH) increases feeding when injected intracerebroventricularly in rats. To identify the hypothalamic nuclei responsible for the orexigenic effect, we injected the peptide into discrete hypothalamic nuclei known to express the MCH receptor, MCH1R. MCH (0.6 nmol) elicited a rapid and significant increase in feeding in satiated rats following injection into the arcuate nucleus (0-1 h: 421 +/- 60%; P < 0.01). An elevation in feeding was also observed following injection into the paraventricular nucleus, which was sustained up to 4 h post injection (0-4 h: 218 +/- 29%; P < 0.01). A significant increase in feeding during this time period was also observed following injection into the dorsomedial nucleus (0-4 h: 155 +/- 12%; P < 0.05). No significant alteration in feeding was observed following injection into the supraoptic nucleus, lateral hypothalamic area, medial preoptic area, anterior hypothalamic area, or ventromedial nucleus of the hypothalamus. To identify the neurotransmitters that may be potentially involved in this effect, we examined their release from hypothalamic explants in vitro following exogenous MCH administration. MCH (1 micro M) increased the release of the orexigenic neurotransmitters neuropeptide Y (37.8 +/- 6.0 fmol/explant vs. basal 30.2 +/- 4.3 fmol/explant; P < 0.05) and agouti-related peptide (4.1 +/- 0.6 fmol/explant vs. basal 2.4 +/- 0.2 fmol/explant; P < 0.05) and decreased the release of the anorectic neurotransmitters alpha-MSH (41.7 +/- 6.8 fmol/explant vs. basal 65.9 +/- 11.0 fmol/explant; P < 0.01) and cocaine- and amphetamine-regulated transcript (112.3 +/- 12.4 fmol/explant vs. basal 167.4 +/- 13.0 fmol/explant; P < 0.001). These studies suggest that the orexigenic effect of MCH may be mediated via activation or inhibition of these feeding circuits within the arcuate nucleus and paraventricular nucleus of the hypothalamus.

The hypothalamic mechanisms of the hypophysiotropic action of ghrelin.

Ghrelin is an endogenous ligand for the growth hormone secretagogue (GHS) receptor, expressed in the hypothalamus and pituitary. Ghrelin, like synthetic GHSs, stimulates food intake and growth hormone (GH) release following systemic or intracerebroventricular administration. In addition to GH stimulation, ghrelin and synthetic GHSs are reported to stimulate the hypothalamo-pituitary-adrenal (HPA) axis in vivo. The aims of this study were to elucidate the hypothalamic mechanisms of the hypophysiotropic actions of ghrelin in vitro and to assess the relative contribution of hypothalamic and systemic actions of ghrelin on the HPA axis in vivo. Ghrelin (100 and 1,000 nM) stimulated significant release of GH-releasing hormone (GHRH) from hypothalamic explants (100 nM: 39.4 +/- 8.3 vs. basal 18.3 +/- 3.5 fmol/explant, n = 49, p < 0.05) but did not affect either basal or 28 mM KCl-stimulated somatostatin release. Ghrelin (10, 100 and 1,000 nM) stimulated the release of both corticotropin-releasing hormone (CRH) (100 nM: 6.0 +/- 0.8 vs. basal 4.2 +/- 0.5 pmol/explant, n = 49, p < 0.05) and arginine vasopressin (AVP) (100 nM: 49.2 +/- 5.9 vs. basal 35.0 +/- 3.3 fmol/explant, n = 48, p < 0.05), whilst ghrelin (100 and 1,000 nM) also stimulated the release of neuropeptide Y (NPY) (100 nM: 111.4 +/- 25.0 vs. basal 54.4 +/- 9.0 fmol/explant, n = 26, p < 0.05) from hypothalamic explants in vitro. The HPA axis was stimulated in vivo following acute intracerebroventricular administration of ghrelin 2 nmol [adrenocorticotropic hormone (ACTH) 38.2 +/- 3.9 vs. saline 18.2 +/- 2.0 pg/ml, p < 0.01; corticosterone 310.1 +/- 32.8 ng/ml vs. saline 167.4 +/- 40.7 ng/ml, p < 0.05], but not following intraperitoneal administration of ghrelin 30 nmol, suggesting a hypothalamic site of action. These data suggest that the mechanisms of GH and ACTH regulation by ghrelin may include hypothalamic release of GHRH, CRH, AVP and NPY.

Prolactin-releasing peptide releases corticotropin-releasing hormone and increases plasma adrenocorticotropin via the paraventricular nucleus of the hypothalamus.

Intracerebroventricular (ICV) injection of prolactin-releasing peptide (PrRP) is known to increase plasma adrenocorticotropin (ACTH) and cause c-fos expression in the hypothalamic paraventricular nucleus (PVN). We hypothesize that this is the site at which PrRP acts to increase plasma ACTH. We have used ICV injection and direct intranuclear injection of PrRP into the PVN to investigate the sites important in the stimulation of ACTH release in vivo. To investigate the mechanism of action by which PrRP increases ACTH, we have used primary culture of pituitary cells and measured neuropeptide release from in vitro hypothalamic incubations. ICV administration of PrRP increased plasma ACTH 10 min post-injection (PrRP 5 nmol 81.0 +/- 23.5 pg/ml vs. saline 16.8 +/- 14.1 pg/ml, p < 0.05). Intra-PVN injection of PrRP increased ACTH 5 min post-injection (PrRP 1 nmol 22.9 +/- 5.0 pg/ml vs. saline 10.3 +/- 1.4 pg/ml, p < 0.05). This effect continued until 40 min post-injection (PrRP 1 nmol 9.9 +/- 1.5 pg/ml vs. saline 6.2 +/- 0.5 pg/ml, p < 0.05). In vitro PrRP (1-100 nmol/l) did not effect basal or corticotropin-releasing hormone (CRH)-stimulated ACTH release from dispersed anterior pituitary cells. PrRP increased hypothalamic release of CRH (PrRP 100 nmol/l 1.4 +/- 0.2 nmol/explant vs. the basal 1.1 +/- 0.2 nmol/explant, p < 0.05) but not arginine vasopressin. PrRP also stimulated neuropeptide Y release (PrRP 100 nmol/l 56.5 +/- 11.8 pmol/explant vs. basal 24.0 +/- 1.9 pmol/explant, p < 0.01), a neuropeptide known to stimulate the hypothalamo-pituitary-adrenal axis. Our data suggest that in vitro PrRP does not have a direct action on the corticotrope but increases plasma ACTH via the PVN and this effect involves the release of hypothalamic neuropeptides including CRH and neuropeptide Y.

The hypothalamic melanocortin system stimulates the hypothalamo-pituitary-adrenal axis in vitro and in vivo in male rats.

alpha-Melanocyte-stimulating hormone (alpha-MSH) is an agonist, and agouti-related protein (Agrp) an endogenous antagonist at the melanocortin 3 and 4 receptors which are found in the central nervous system (CNS). We have examined the effect of alpha-MSH and Agrp on the hypothalamo-pituitary-adrenal (HPA) axis in vitro and in vivo in male rats. Intraparaventricular nuclear (iPVN) injection of [Nle(4),D-Phe(7)]-alpha-MSH (NDP-MSH) (a long-acting alpha-MSH analogue) increased plasma adrenocorticotropic hormone (ACTH) (10 min post-injection: 25.0 +/- 3.9 vs. saline 10.9 +/- 2.0, p < 0.05) and plasma corticosterone (10 min post-injection: 174.1 +/- 14.2 vs. saline 124.7 +/- 16.3 ng/ml, p < 0.05). iPVN injection of Agrp(83-132) increased plasma ACTH (24.2 +/- 4.0 vs. saline 10.1 +/- 1.0 pg/ml, p < 0.01). The combination of NDP-MSH and Agrp(83-132) administered iPVN significantly increased plasma ACTH (10 min post-injection: 21.3 +/- 3.8 vs. 10.9 +/- 2.0, p < 0.05) and plasma corticosterone (10 min post-injection: 169.0 +/- 15.1 vs. saline 124.7 +/- 16.3 ng/ml, p < 0.05), but there was no additive effect. Hypothalamic explants treated with alpha-MSH (100 nM) resulted in a 159 +/- 23% increase in corticotropin-releasing hormone (CRH) release (p < 0.01) and 175 +/- 12% increase in arginine vasopressin (AVP) release (p < 0.001) compared to basal. Agrp(83-132) (100 nM) administered to hypothalamic explants resulted in a 161 +/- 20% increase in CRH (p < 0.01) and 174 +/- 13% increase in AVP release (p < 0.001) compared to basal. Hypothalamic explants treated with the combination of alpha-MSH and Agrp(83-132) (100 nM) resulted in a 179 +/- 31% increase in CRH release (p < 0.01) and 130 +/- 9% increase in AVP release (p < 0.01) compared to basal, but there was no additive effect. This is the first report that both alpha-MSH and Agrp(83-132) stimulate the HPA axis. The combination of alpha-MSH and Agrp(83-132) has no additive effect in vitro and in vivo in male rats. These results suggest that there may be another receptor independent of the known melanocortin receptors at which Agrp is acting.
