Androgen receptor expression in the cervix of androgen-treated female-to-male transsexuals: association with morphology and chain-specific keratin expression

Effect of testosterone therapy on migraine frequency and disability in two transgender patients: a case report

With an increasing number of patients seeking gender-affirming hormone therapy (GAHT), the clinical impact of testosterone treatments on headache needs to be determined. Our case report looks at the potential effect of testosterone on migraine among transgender patients. We present two transmasculine patients who used masculinising hormone therapy with testosterone. Both patients described their headache as moderate-to-severe pain with features that fulfilled the criteria for chronic migraine without aura. Following GAHT, one patient improved in both frequency and intensity of headache symptoms while the other noted improvement in headache intensity alone. Our report postulates that testosterone therapy may have a positive impact on headaches in individuals participating in GAHT, highlighting the need for further research on the role of testosterone therapy on headache in transmasculine individuals.

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

CONTEXT.—

Transgender men and transmasculine persons experience a discordance between the female sex they were assigned at birth and their gender. They may choose to take hormone therapy and/or undergo surgery to masculinize the body. Understanding the common (and less common) histologic changes present in patients taking masculinizing hormones will empower pathologists to better serve this unique patient population.

OBJECTIVE.—

To summarize histologic findings in surgical pathology specimens from persons taking masculinizing hormones as a part of gender transition.

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 men from January 1946 to January 2021.

CONCLUSIONS.—

Publication in this area has markedly increased in the last 2 decades. However, most of the studies identified were descriptive and case reports describing changes seen in specimens removed as a part of masculinizing surgical procedures. Benign histologic findings include stromal hyalinization and epithelial atrophy in the breast, polycystic ovarian syndrome-like changes in the ovary, and transitional cell metaplasia in the cervix. The most commonly reported neoplastic finding was adenocarcinoma of the breast, with rare cases of ovarian, endometrial, cervical, vaginal, pituitary, pancreatic, and cardiovascular neoplasia also reported. Ongoing research in this area is needed to better characterize the histologic findings in persons taking masculinizing hormones to provide a deeper understanding of the effect of these treatments on different tissues and facilitate better patient management.

Characteristic findings of cervical Papanicolaou tests from transgender patients on androgen therapy: Challenges in detecting dysplasia

INTRODUCTION

The characteristic features of Papanicolaou (Pap) tests collected from female-to-male (FTM) transgender patients on androgen therapy have not been well defined in the literature. FTM transgender patients require cervical cancer screening with the same recommended frequency as cis-gender females. Dysplasia remains challenging to differentiate from atrophy. Without pertinent history, the atrophic findings in younger transgender patients can be misinterpreted as high-grade dysplasia.

METHODS

A review of all cervical Pap tests of transgender patients receiving androgen therapy (2010-2017) was performed. Bethesda diagnosis, cytomorphological features, HPV testing and cervical biopsy results were reviewed.

RESULTS

Eleven transgender patients receiving androgen therapy were identified with 23 cervical Pap tests, 11 HPV tests and five cervical biopsies performed. A review of the Pap tests demonstrated: 57% negative for intraepithelial lesion; 13% unsatisfactory; 13% atypical squamous cells of undetermined significance; 13% atypical squamous cells - cannot exclude high-grade squamous intraepithelial lesion; and 4% high-grade squamous intraepithelial lesion. The rates of abnormal tests were higher than our age-matched cis-gender atrophic cohort rates of unsatisfactory (0.5%), atypical squamous cells of undetermined significance (7%), atypical squamous cells-cannot exclude high-grade squamous intraepithelial lesion (0%) and high-grade squamous intraepithelial lesion (0.5%). The cytological findings from liquid-based preparations included dispersed and clustered parabasal-type cells, scattered degenerated cells, smooth evenly dispersed chromatin, and occasional mild nuclear enlargement and irregularity. Dysplastic cells had larger nuclei, hyperchromatic clumped chromatin, and more irregular nuclear contours.

CONCLUSIONS

The evaluation of dysplasia can be challenging on Pap tests from transgender patients on androgen therapy. The cohort evaluated had higher rates of unsatisfactory and abnormal Pap tests. Pathologists should be familiar with the distinctive cytomorphological changes in the Pap tests from patients on androgen therapy to evaluate them appropriately.

Female-to-male patients have high prevalence of unsatisfactory Paps compared to non-transgender females: implications for cervical cancer screening

BACKGROUND

Little is known about whether and how screening for cancers of natal reproductive structures, including cervical cancer, in female-to-male (FTM) transgender individuals differs from cancer screening among non-transgender females.

OBJECTIVE

To investigate anecdotal reports from clinicians of high rates of inadequate Papanicolaou (Pap) tests among transgender men.

DESIGN

Results of Pap tests performed on 233 FTM and 3,625 female patients at an urban community health center between 2006 and 2012 were extracted from an electronic medical record.

KEY RESULTS

Compared to female patients, FTM patients were more likely to have an inadequate Pap, with prevalence of inadequate samples 8.3 times higher among tests of FTM patients (10.8% vs. 1.3% of tests). FTM patients had over ten times higher odds of having an inadequate Pap after adjusting for age, race, and body mass index (AOR = 10.77, 95% CI = 6.83, 16.83). When years on testosterone therapy was added to the model, the relationship between transgender identity and Pap inadequacy was attenuated, but remained strongly associated (AOR = 6.01, 95% CI = 3.00, 11.50), and time on testosterone was also associated (AOR = 1.19, 95% CI 1.04, 1.36). FTM patients were more likely than females to have had multiple inadequate tests, and had longer latency to follow-up testing.

CONCLUSIONS

The high unsatisfactory sample prevalence among FTM patients is likely due to a combination of physical changes induced by testosterone therapy and provider/patient discomfort with the exam. Clinicians should receive training in increasing comfort for FTM patients during the exam. FTM patients should be alerted that high rates of inadequate screening may require follow-up testing. Alternatives to repeated Pap testing, such as cytologic reprocessing of inadequate samples or primary human papillomavirus (HPV) DNA screening, should be studied for efficacy and acceptability among FTM patients.

Androgens in pregnancy: roles in parturition

BACKGROUND

Understanding the physiology of pregnancy enables effective management of pregnancy complications that could otherwise be life threatening for both mother and fetus. A functional uterus (i) retains the fetus in utero during pregnancy without initiating stretch-induced contractions and (ii) is able to dilate the cervix and contract the myometrium at term to deliver the fetus. The onset of labour is associated with successful cervical remodelling and contraction of myometrium, arising from concomitant activation of uterine immune and endocrine systems. A large body of evidence suggests that actions of local steroid hormones may drive changes occurring in the uterine microenvironment at term. Although there have been a number of studies considering the potential role(s) played by progesterone and estrogen at the time of parturition, the bio-availability and effects of androgens during pregnancy have received less scrutiny. The aim of this review is to highlight potential roles of androgens in the biology of pregnancy and parturition.

METHODS

A review of published literature was performed to address (i) androgen concentrations, including biosynthesis and clearance, in maternal and fetal compartments throughout gestation, (ii) associations of androgen concentrations with adverse pregnancy outcomes, (iii) the role of androgens in the physiology of cervical remodelling and finally (iv) the role of androgens in the physiology of myometrial function including any impact on contractility.

RESULTS

Some, but not all, androgens increase throughout gestation in maternal circulation. The effects of this increase are not fully understood; however, evidence suggests that increased androgens might regulate key processes during pregnancy and parturition. For example, androgens are believed to be critical for cervical remodelling at term, in particular cervical ripening, via regulation of cervical collagen fibril organization. Additionally, a number of studies highlight potential roles for androgens in myometrial relaxation via non-genomic, AR-independent pathways critical for the pregnancy reaching term. Understanding of the molecular events leading to myometrial relaxation is an important step towards development of novel targeted tocolytic drugs.

CONCLUSIONS

The increase in androgen levels throughout gestation is likely to be important for establishment and maintenance of pregnancy and initiation of parturition. Further investigation of the underlying mechanisms of androgen action on cervical remodelling and myometrial contractility is needed. The insights gained may facilitate the development of new therapeutic approaches to manage pregnancy complications such as preterm birth.

Cross-sex hormone administration changes pain in transsexual women and men

Chronic pain is gender-related, since there is a clear predominance of one sex with respect to the other in most pain syndromes. Gonadal hormones are known to affect the occurrence and incidence of pain. Transsexuals receive cross-sex hormones to develop and maintain somatic characteristics of the opposite sex: male to female transsexuals (MtF) are administered estrogens and anti-androgens, while female to male transsexuals (FtM) are administered androgens. Hence, these subjects represent a model to study the relationship between sex hormones and pain. Questionnaires dealing with sociodemographic data and pain (occurrence, frequency, duration, intensity, location and associated symptoms) were administered to both MtF and FtM transsexuals under hormone treatment for sex reassignment for at least 1 year. Forty-seven MtF and 26 FtM completed the questionnaires. Fourteen of the 47 MtF (29.8%) reported painful conditions, which in 11 subjects were not present before the beginning of hormone treatment. Pain consisted mainly of headaches and breast and musculoskeletal pain. Five subjects suffered from more than one pain condition. Sixteen of the 26 FtM (61.5%) reported pain. In 11 subjects, the pain was present before the beginning of hormone intake, and in 6 of them it improved after testosterone administration. These data suggest that marked changes in sex hormones affect the occurrence of pain in a high percentage of humans but not in all of them. Whether these effects are due to peripheral or central actions of sex steroids is unknown.

Ectopic Prostatic Tissue in the Uterine Cervix and Vagina

Prostatic tissue has rarely been described in the lower female genital tract. We describe 6 cases of ectopic prostatic tissue: 5 involving the cervix and 1 the vagina. The latter is the first reported example of benign prostatic tissue in the vagina. The age of the patients ranged from 21 to 65 years; and in all cases, the prostatic tissue was located within the cervical or vaginal stroma without involvement of the surface. In all cases, there were both glandular and squamous elements, which varied in prominence. In some cases, the squamous elements predominated to such an extent that the underlying glandular component was easily overlooked. In the glandular areas, a double cell layer of luminal and basal cells was focally apparent. There was little cytologic atypia or mitotic activity. Immunohistochemically, 3 of 6 cases were positive with prostate specific antigen (PSA) and all 6 cases marked with prostatic acid phosphatase (PSAP). In some of the positive cases, staining was focal. Positive staining with prostatic markers was confined to the glandular elements with no staining of the squamous areas. Immunohistochemical staining with the high molecular weight cytokeratin 34betaE12 highlighted the basal cell layer, which often extended into the center of the cellular islands, reminiscent of basal cell hyperplasia involving the prostate gland. All cases tested were CD10 positive (largely restricted to the basal cell layer), alpha-methylacyl-CoA racemase positive, and p16 negative. Estrogen receptor (ER) and progesterone receptor (PR) were negative in the glandular areas, but ER was positive in the squamous elements in all cases and PR was positive in 1 case. All cases tested were androgen receptor positive and exhibited a low MIB-1 proliferation index with only scattered positive nuclei. The presence of ectopic prostatic tissue in the lower female genital tract may be more common than is appreciated. Once the possibility is considered, the diagnosis is easily confirmed using immunohistochemistry, although staining with prostatic markers may be focal and PSA may be negative. Ectopic prostatic tissue in the lower female genital tract is almost certainly a benign condition, based on the morphology, including the presence of a double cell layer, although follow-up of larger numbers of cases is required. Possible theories of histogenesis include a developmental anomaly, metaplasia of preexisting endocervical glands, and derivation from mesonephric remnants.

Roles of androgens in the development, growth, and carcinogenesis of the mammary gland

Androgens influence the development and growth of the mammary gland in women. Treatment of animals and cultured cells with androgens has either inhibitory or stimulatory effects on the proliferation of mammary epithelia and cancer cells; the mechanisms for these dual functions are still not very clear and are discussed in this review. Epidemiological data suggest that, similar to increased estrogens, elevated androgens in serum may be associated with the development of breast cancer. Experiments in rodents have also shown that simultaneous treatment of androgen and estrogen synergizes for mammary gland carcinogenesis. Similar synergistic effects of both hormones have been observed for carcinogenesis of the uterine myometrium of female animals and for carcinogenesis of the prostate and deferens of males. There are also clinical and experimental indications for a possible association of elevated levels of both androgens and estrogens with the development of ovarian and endometrial cancers. A hypothesis is thus proposed that concomitant elevation in both androgens and estrogens may confer a greater risk for tumorigenesis of the mammary gland, and probably other female reproductive tissues than an elevation of each hormone alone.
