Low dose of propyl-pyrazole-triol, an agonist of estrogen receptor alpha, administration stimulates the Coolidge effect in fadrozole-treated male rats.

Estrogen receptor (ER) α is involved in male sexual function. Here, we aim to investigate how ERα activation influences sexual satiety and the Coolidge effect (i.e., when a rat, that has reached sexual satiety, experiences an increased arousal after exposure to a novel sexual partner) in estrogen-deprived male rats. Male rats (8 per group) were treated daily for 29 days with either saline (Control group) or fadrozole dissolved in saline (1 mg/kg/day) 1 h before mating. On Days 13 and 29, rats treated with fadrozole received either no additional treatment (fadrozole group) or a single injection of propyl-pyrazole-triol (ERα-agonist group, dissolved in sesame oil, 1 mg/kg). Rats mated until reaching sexual satiety on Days 13 and 29. In these sessions, the Control group displayed higher frequency of intromission and ejaculation than the other groups. The ERα-agonist group mounted more frequently but reached sexual satiety sooner than the Control group. On Day 29, when exposed to a new sexual partner, the fadrozole-treated rats were less likely to display intromission than the other groups, or ejaculation than the Control group, or mounting than the ERα-agonist group. The Control group showed more ejaculatory behavior and shorter ejaculation latency than the other groups. Body weights, testosterone levels, estradiol levels, and ERα-immunoreactive cell counts in brain regions for sexual behavior were comparable between groups after 29 days of treatments. Our data suggest that estrogen helps regulate sexual satiety and the Coolidge effect in male rats.

Reasons for why Medical Students Prefer Specific Sleep Management Strategies.

OBJECTIVES: Insomnia symptoms are common among medical students. This study explored the perspectives of medical students about which sleep management strategies to use. METHODS: Medical students responded to an online survey on their thoughts about the use of various sleep management strategies. RESULTS: Of the 828 respondents, 568 (69%) provided responses to questions about the most preferred strategies and 450 (54%) provided responses about their least preferred strategies. About 48.5% felt their insomnia symptoms were too mild to see a clinician and 23.9% did not think their symptoms warranted sleep medication. Over 40% of students could not avoid work before sleep, have consistent sleep/wake times, or engage in regular exercise because of their busy and inconsistent schedules. Approximately 40-60% could not improve their sleep environment (e.g. better heating and bed) because of the associated costs. Over 80% reported an inability to change their pre-sleep habits (e.g. using electronics close to bedtime, using bed for activities other than sleep or sex). Half of the students disliked relaxation techniques or felt they would not help. Around 30-50% did not believe that changing caffeine and/or alcohol intake would affect their sleep. CONCLUSIONS: Medical students may benefit from additional sleep education. Clinicians may need to discuss which strategies individual students prefer and modify their recommendations accordingly.

Choosing Castration: A Thematic Analysis of the Perceived Pros and Cons of Genital Injuries and Ablation by Men Who Voluntarily Sought Castration.

Some men elect castration voluntarily without any clear medical reason. Here we aim to document their perception of genital ablation and injuries to better understand their motivations for castration. Participants completed an online survey with open-ended questions related to their perspectives on castration, genital ablation, and genital injuries. Thematic analyses were performed on the responses to these questions. Responses were obtained from 208 male castrated individuals (51.9 ± 16.0 years old). Among these, 154 were physically castrated, 36 chemically castrated, and 18 nullified (had testicles and penis removed). The majority learned about castration from media (55.8%) or animal castration (23.4%). The circumstances when they first wanted to be castrated varied greatly. Most (46.3%) wished to achieve an idealized self motivated by gender dysphoria, body integrity dysphoria, or wanting to be conspicuously non-sexual. The top themes we identified related to the respondents' perceptions of the pros of genital ablation were physical appearance, psychological benefit (i.e., a "eunuch calm"), and being non-sexual. Conversely, themes related to the cons they saw in having no genitals ranged from no disadvantages to loss of sexual/reproductive capability. Some perceived performing genital injury as a step toward ultimate castration or nullification. The respondents similarly varied in whether they saw any loss in having non-functional testicles. Perceptions in this regard appeared to differ depending on whether the respondents were taking supplemental androgens post-castration. Motivations for castration vary greatly between individuals. Clinicians need to understand men's diverse perceptions on castration in order to provide appropriate care for individuals with strong castration desire.

Sleep Management Strategies Among Medical Students At the University of Otago.

OBJECTIVES: We aim to investigate factors which might affect the sleep of medical students, and how they currently manage their sleep. METHODS: An online survey was sent to medical students at the University of Otago. RESULTS: After adjusting for gender, ethnicity and age, depressive symptoms (Mild: odds ratio (OR) = 6.3; Moderate: OR = 18.1; Severe: OR = 15.6), and sleep hygiene (OR = 1.07) were associated with insomnia symptoms. Commonly endorsed strategies for sleep management by students were undertaking regular exercise (80.1%), having consistent sleep-wake time (71.3%), and limiting caffeine intake (70.3%). Few were willing to see a clinician (23.4%) or take medication (22.3%). Participants with insomnia symptoms were more likely to prefer limiting their alcohol intake (OR = 1.8), limiting daytime naps (OR = 1.5), seeing clinicians (OR = 1.9), and taking sleep medication (OR = 4.0), but less likely to prefer avoiding intense work (OR = .71) or minimizing using electronics (OR = .60) close to bedtime than those without insomnia symptoms. High sleep self-efficacy was associated with lower odds for having insomnia symptoms (OR = .74 (.70, .77)). CONCLUSIONS: Increased awareness and greater resources are needed to support the sleep health of medical students.

The relationship between sleep hygiene, mood, and insomnia symptoms in men with prostate cancer.

PURPOSE: Insomnia symptoms are commonly experienced by men after prostate cancer (PCa) treatment. Here we explored how sleep hygiene behaviours and psychological symptoms are associated with insomnia symptoms in PCa patients. METHODS: An online survey was posted on social media and sent to mailing lists of PCa and general cancer organisations. The survey collected information on demographic, sleep hygiene, and psychological symptoms using validated questionnaires. RESULTS: Data from 142 participants were compared based on the absence (age = 68.3 ± 8.9 years) and presence (age = 66.6 ± 9.0 years) of insomnia symptoms. Participants with insomnia symptoms had significantly higher levels of anxiety, depression, fatigue, and sleepiness as well as poorer sleep hygiene than those without insomnia symptoms. Control variables (age, number of comorbidities, and BMI) accounted for 11.9% of the variance in insomnia symptoms. Including treatment history contributed to an additional 1.6% of the variance in insomnia symptoms. Adding sleepiness, fatigue, anxiety, and depressive symptoms to the model explained an additional 44.6% of the variance in insomnia symptoms. Furthermore, including the sleep hygiene item 'I think, plan, or worry when I am in bed' and 'I sleep in an uncomfortable bedroom' explained an additional 3.6% of the variance in insomnia symptoms. CONCLUSIONS: Poor sleep hygiene, fatigue, sleepiness, anxiety, and depressive symptoms were all associated with worse insomnia symptoms in PCa patients. Improving sleep hygiene and treating psychological conditions may potentially help prevent and/or alleviate insomnia symptoms in PCa patients.

Paraphilic Sexual Attraction to Males Without Genitals Is Associated with Traumatic Childhood Experience, Body Image, and Thoughts/Behaviors Related to Genital Ablation.

In rare cases, some male individuals are sexually attracted to men who have their genitals removed. We investigate here if paraphilic attraction to men without genitals was associated with childhood experience, body image, and thoughts/behaviors related to body modification. An online survey, consisting of both validated questionnaires and questions developed by our team, was launched on the Eunuch Archive and MTurk websites. Out of 875 participants, 48.5 and 32.2% reported being attracted to males without testicles or without a penis, respectively; 49.7 and 31.0% felt they would themselves be attractive without testicles and without a penis, respectively. In terms of body modification, many reported having tattoos (19.0%) and piercings (26.1%). About half (48.3%) had played as children with male action figures without genitals, i.e., GI Joe, and Ken dolls. Additionally, some participants reported having: (1) witnessed animal castration (23.7%); (2) having been threatened with castration during their childhood (11.9%); (3) receiving genital injuries inflicted by others (11.0%); (4) pretending to be castrated (60.2%); (5) thinking of self-castration (54.2%); or (6) injuring their own penis (23.4%). Having received genital injuries inflicted by others was associated with attraction to males without testicles (OR = 1.997, p < .05), but not for attraction to males without a penis. Paraphilic attraction to males without genitals (i.e., castrated or penectomized) was associated with feeling attractive without genitals, having pretended to be castrated, considering self-castration, and having injured one's own penis. In conclusion, paraphilic attraction to males without genitals may be associated with traumatic early life events, body image, and desire for one's own genital ablation.

Hormones and visual attention to sexual stimuli in older men: an exploratory investigation.

BACKGROUND: Testosterone is associated with sexual desire and performance in men, but little is known about cognitive mechanisms underlying this relationship. Even less is known about the influence of estradiol, despite its production from testosterone, and high receptor density in brain regions related to male sexual behavior. METHOD: We used eye-tracking to compare men's visual attention to images of fully clothed (i.e. neutral) and minimally clothed (i.e. sexy) models in three groups: androgen-deprived (n = 6) and not androgen-deprived with prostate cancer (n = 11), and healthy controls (n = 7). We also assessed effects of serum testosterone, estradiol, and sex hormone-binding globulin levels. RESULTS: We found no group effect for fixations to sexy compared to neutral images, and no influence of testosterone on either total fixations, or proportion of fixations to sexy images. In contrast, we found that sex hormone binding globulin positively predicted total fixations, and estradiol positively predicted proportion of total fixations on sexy images--regardless of androgen treatment status. CONCLUSION: Our results suggest that visual attention to sexual stimuli in men may be significantly affected by hormones. This has potential implications for clinical populations that experience sexual side effects, such as prostate cancer patients on androgen deprivation therapy.

The Association between Insomnia and Orgasmic Difficulty for Prostate Cancer Patients - Implication to Sex Therapy.

Sexual dysfunction and insomnia are common side effects of prostate cancer (PCa) treatment, but the link between these symptoms has not been explored. We explore here the association between various sexual parameters and insomnia symptoms in PCa patients. Data were collected via an online survey with recruitment through various PCa organizations. One hundred and forty two patients (age = 67.3 ± 8.9 years) completed the survey. The majority were in a relationship (84.6%), of Caucasian ethnicity (83.1%), and 33% had previously received androgen deprivation therapy (ADT). Control variables-age, number of comorbidities, past ADT use, body mass index, depression, anxiety, fatigue and daytime sleepiness-explained 58.2% of the variance for insomnia symptoms. Including orgasm difficulty in the models accounted for an additional 2.1% in the variance in insomnia symptoms. Conversely, the control variables listed above together with insomnia symptoms predicted 37.7% of the overall variance in orgasm difficulty in PCa patients. These data suggest that sexual rehabilitation programs for PCa patients should assess insomnia symptoms, and therapies to improve sexual function or sleep quality may be beneficial in both functions given the relationship between sleep and orgasm functions in this population.

Sexual Function After Voluntary Castration.

Some genetic males undergo voluntary castration, with and without hormonal supplementation. Here, we investigate the sexual function of 163 such individuals (average age = 52 ± 16-years-old). Specifically, we explored how hormonal, social, and psychological factors play a role in their sexual function. In this study, 47% identified their gender as "eunuch", and 36% identified their gender as "man." Furthermore, 64% were in a relationship (80% with a woman), and 28% had a strong attraction for both sexes (Kinsey 2-4). We found that castrated individuals with androgen supplementation have higher sexual function than those without any hormone supplementation. Individuals with anxiety symptoms reported better sexual parameters (better orgasm satisfaction, easier to achieve an erection and an orgasm) than those without anxiety symptoms. Among those low in anxiety, individuals without hormone supplementation had a weaker sex drive and more difficulty in getting sexually aroused than those on supplemental estrogen or androgen. Hierarchical multiple regressions indicated that control variables (i.e., age, depressive symptoms, time since castration, type of hormone supplementation) accounted for 13-30% of the variances in sexual parameters. Including sexual guilt in the models predicted 4-8% additional variances in all sexual parameters except for ease in getting and maintaining an erection. Adding in participants' sexual trauma scores accounted for an additional 3.7% in the strength of their reported sex drive. In conclusion, various factors-hormone therapy, anxiety, sexual guilt, and childhood trauma-may influence the sexual outcomes for castrated individuals.

Differences in the Psychological, Sexual, and Childhood Experiences Among Men with Extreme Interests in Voluntary Castration.

Some genetic males seek voluntary castration. We designed a survey to compare the psychological, sexual, and childhood experiences for subgroups of men with extreme interest in castration. The survey was posted on the Eunuch Archive, an online platform for individuals interested in the topic. Data from 822 individuals were included in the analyses. Respondents were divided into four groups: Interested (claiming only an interest in castration topics), Fantasy (fantasize about castration sexually, but not desiring castration), Wannabe (considering being castrated in the future), and Castrated (already castrated). More individuals desiring castration (Wannabe and Castrated groups) claimed equal attraction to both sexes than individuals in the Interested group. The Interested group was more religious than the other groups, and the Fantasy group had lower sexual guilt than those with castration desire. All groups had similar psychological well-being and body image acceptance, despite the Castrated group having lower sexual functioning than the others. Childhood trauma was more common in those with castration desire than those without. The Interested group had a lower desire for castration, lower erotic attraction to castration, and pretended to be castrated at a younger age than the others. Childhood trauma and sexual guilt are common, but not limited, predictors for castration desire and erotic attraction to castration, respectively. In conclusion, childhood experiences, as well as psychological and sexual parameters, may vary in different subgroups of males with interests in castration.

Psychosocial Barriers and Enablers for Prostate Cancer Patients in Starting a Relationship.

Single prostate cancer (PCa) patients may face difficulties in starting a new relationship for various reasons. Here, we studied barriers and enablers to starting a relationship for PCa patients and characteristics of patients who were and were not in a relationship. PCa organizations distributed for us a 20-minute online survey, consisting of validated questionnaires (on treatment side effects, loneliness, social provision, and shyness) and questions on factors identified by patients as barriers and enablers to forming a new relationship. Participants were either single [n = 20] or had started a new relationship post-diagnosis [non-single, n = 15]. Three factors-confidence, sexual function, finding the right person-were perceived of as factors that can affect starting a relationship. Fourteen of twenty single patients were confident that they could find a partner and sixteen were comfortable in disclosing their cancer diagnosis to a potential partner. Non-single patients met their partners through various ways, including online dating and social events. They all revealed their cancer status prior to starting the relationship, and most partners reacted well to this disclosure. Single patients were lacking emotional support, more shy, and lonelier than non-single patients. Clinicians need to consider biopsychosocial factors when advising single patients who wish to start a new relationship.

Characteristics of Males Who Obtained a Voluntary Penectomy.

We report here on survey data from 11 genetic males, who had voluntary penectomies without any explicit medical need, yet did not desire testicular ablation. This group was compared to a control group of men who completed the same survey but had no genital ablation. The penectomy group was less likely to identify as male than the control group. They were also more likely to have attempted self-injury to their penis (at a median age of 41.5 years), been attracted to males without penises, and felt that they were more physically attractive without a penis than the controls. Motivations for voluntary penectomy were aesthetics (i.e., a feeling that the penile removal made them more physically attractive) or eroticism (i.e., at least two individuals thought that a penectomy would make them a better submissive sexual partner). In terms of sexual function, the penectomized and control groups reported comparable sexual function, with six penectomized individuals claiming to still be able to get and keep an erection, suggesting possible incomplete penile ablation. In their childhood, penectomized individuals were more likely than the controls to have pretended to be castrated and to have involved the absence of genitals of their toys in their childhood play. We discuss characteristics and sexual outcomes for individuals who have had a voluntary penectomy. A future study with a larger sample size on men who desire penectomies is warranted.

Variation in perceptions of genital ablation between aspiring eunuchs and individuals with paraphilic sexual fantasies.

Background: Although uncommon, some individuals assigned male at birth (AMAB) seek voluntary genital ablative procedures, and others fantasize about it. Aim: To learn more about the views of genital ablation and injuries in those who aspire to be castrated as compared with those who only fantasize about it. Methods: A survey was run on the Eunuch Archive internet community. Content analysis was conducted on the responses of 342 AMAB individuals with castration fantasy but no desire for actual surgery (fantasizers) vs 294 AMAB individuals who expressed a desire for genital ablation (aspiring). Outcomes: Study outcomes were responses to open-ended questions about genital ablations and injury. Results: Aspiring individuals were more likely to perceive a "physical appearance benefit" from orchiectomy, but fewer could recall how they first learned about the procedure. Some reasons that aspiring persons gave for desiring an orchiectomy included "achieving preferred self" and "health reasons." Fantasizers, in contrast, worried about the potential side effects of orchiectomy, and more believed there to be no benefit to it. Clinical Implications: Psychiatrists and other clinicians need to understand their patients' views on genital ablation to properly diagnose and provide the best personalized care. Strengths and Limitations: Strengths include a large sample of respondents. Limitations include the accuracy of the anonymous survey data. Conclusions: This study demonstrates divergent interests on genital ablation among AMAB individuals who have not had an any genital ablation yet have intense interest in the topic.

The Relationship Between Academic Stress, Sleep Quality, and Psychological Wellbeing in Pasifika and New Zealand European Students at the University of Otago.

BACKGROUND: Pasifika students in New Zealand are overrepresented in poor academic outcomes, and their academic challenges may potentially influence their wellbeing. We aim to: 1) compare the academic stress, sleep quality, and psychological wellbeing of Pasifika and New Zealand European (NZE) anatomy students at the University of Otago, and 2) determine if academic stress mediates the association between their psychological wellbeing and sleep quality. METHODS: We launched a brief online survey to Pasifika and NZE students in our department. The survey included basic demographics, Perception of Academic Stress Scale, Pittsburgh Sleep Quality Index, Hospital Anxiety and Depression Scale, a short loneliness scale, a reduced morningness-eveningness scale, and the Epworth Sleepiness Scale. RESULTS: Perceived academic stress were comparable between NZE and Pasifika students, but Pasifika students reported poorer sleep quality than NZE students (t(113) = 14.41, P < .001). In addition, Pasifika students reported more loneliness (t(119) = 8.933, P < .001), less anxiety symptoms (t(120) = 2.469, P = .015), and less of a morning person (t(121) = 2.618, P = .010) than NZE students, but they had comparable depressive symptoms and daytime sleepiness. After controlling for age, ethnicity and gender, we found that academic stress fully mediated the relationship between anxiety or depressive symptoms and poor sleep quality. Furthermore, academic stress partially mediated the relationship between loneliness and poor sleep quality in our cohort. CONCLUSION: Our findings highlight the importance for academic institutions to support students' wellbeing, including ethnic minority students such as Pasifika students in New Zealand.

Does religiosity play a role in anatomy learning? Perspectives from Pasifika students at the University of Otago.

Religion is an important aspect in Pacific cultures and may influence how Pasifika students learn anatomy. Traditional constructs in Pacific cultures, such as tapu (forbidden/taboo) and sacred relationships, and/or Christian values are where spirituality is most commonly perceived among Pacific people. Although Pacific people are not homogenous, tapu is a concept that permeates all of Pacific cultures. Understanding the significance of tapu in Pacific communities will help govern relationships and interactions between male and female students/educators, as well as between the dead (e.g., body donors) and the living (e.g., students/educators). In Pacific communities, breaching tapu can lead to serious repercussions, thus strict adherence to cultural practices is important. Institutions in Aotearoa New Zealand, however, are governed by Western processes and values which are often incompatible with Pasifika worldviews and values. Pacific values, including in education, are holistic in understanding and action, and considers not only the physical but the emotional, mental, and spiritual aspects. The lack of cultural competency and responsiveness from universities continues to be a barrier for Pasifika learners. Supportive action from educators requires appreciation and understanding of Pacific values and practices. Throughout this article, we discuss Pacific perspectives on how religiosity plays a role in anatomy learning for Pasifika students. Key topics discussed here include the Bible, tapu (sacred/taboo), tulou (permission/excuse), va tapu'ia (sacred relationship), nudity, organ donation, and perspectives on working with deceased human bodies. Given the increasing number of Pasifika students enrolled in universities across Aotearoa New Zealand, education institutions should be more culturally-responsive to Pasifika students' needs to enhance their academic success in anatomy education.

Anatomical sciences education needs to promote academic excellence of ethnic minority students-Evidence from Pasifika students at the University of Otago.

The Department of Anatomy at the University of Otago offers anatomical sciences education for various programs, but currently, little information is available on how the academic performance of anatomy students differ based on ethnicities. Here, we aim to determine if there is an ethnic disparity in academic performance among anatomy students at the University of Otago. We conducted a 5-year review of academic performance of New Zealand European (NZE) and Pasifika students in 10 undergraduate anatomy courses, including clinical anatomy, neuroscience, reproduction, cell biology, and biological anthropology. NZE students achieved higher marks than Pasifika students in each academic year for four courses and in 3-4 of 5 academic years for the remaining courses. In eight courses, there were higher proportions of Pasifika students than NZE students who repeated the courses (in 4-5 of 5 academic years for two courses, in 1-2 of 5 academic years for six courses). Multiple regression analyses showed that Pasifika students were more likely to achieve lower marks than NZE students in all courses. Other predictors for academic marks included year of study for five courses, age for three courses, international student status for two courses, major specialization for eight courses, home location for one course, and gender for one course. Data from this research provide evidence that ethnic inequity may exist in anatomical sciences education, and can be used by institutions globally to justify evaluating their anatomy programs, with the aim to better support ethnic minority students who may be struggling academically.

Exposures to information about castration and emotional trauma before puberty are associated with men's risk of seeking genital ablation as adults.

Background: Little is known about childhood experiences, outcomes, and self-recollections of those men who were voluntarily castrated as adults. Aim: The study sought to determine how learning about castration before and after 13 years of age is associated with differential childhood experiences, outcomes, and self-recollections of those who were voluntarily castrated as adults. Methods: We designed a survey of voluntarily castrated individuals, who learned about castration before and after 13 years of age. Our survey consisted of both validated questionnaires and questions. Data were from 208 individuals. Both descriptive and quantitative statistics were performed. Outcomes: Learning about castration before 13 years of age is associated with more adverse childhood experiences (ACEs) such as being threatened with castration and other forms of emotional, physical, and sexual trauma. Results: As compared with those who learned about castration after 13 years of age, those who knew about castration earlier were more likely to have self-injured their penis (χ2 1 = 5.342, P < 0.05), had thoughts of performing self-castration (χ2 1 = 10.389, P < 0.01), witnessed animal castration (χ2 1 = 10.023, P < 0.01), been threatened with castration as a child (χ2 1 = 21.749, P < 0.001), had childhood physical trauma (χ2 1 = 4.318, P < 0.05), had childhood emotional trauma (χ2 1 = 3.939, P < 0.05), and had childhood sexual trauma (χ2 1 = 5.862, P < 0.05). Clinical Implications: Mental health screening and support should be offered to any men seeking emasculating procedures in line with the World Professional Association of Transgender Health's Standards of Care Version 8. Strengths and Limitations: This study had a large sample size and used a validated questionnaire to evaluate for ACEs. The average age of respondents was above 50 years of age, which may increase recall bias. Conclusion: Understanding how ACEs influence the age when some eunuchs first desire, pretend, and become castrated can help clinicians develop better assessments and treatment protocols for individuals with male-to-eunuch gender dysphoria, and other conditions in which emasculating medical procedures are requested.

Job prospects and career pathways for human anatomy graduates from the University of Otago: Implications for student support and professional development.

The Department of Anatomy (Anatomy) at the University of Otago delivers programs for students in diverse areas, including clinical anatomy, neuroscience, reproduction and biological anthropology. This study explored the experiences of alumni during their study and career pathways post-graduation through an online questionnaire distributed to department alumni. Most of the 190 participants studied anatomy as undergraduates (74.2%) and graduated in the past decade (56.8%). Reasons for taking anatomy included finding the topic interesting, a pathway into professional programs, or a degree requirement. Current employment differed between undergraduate (44.7% currently employed in clinical settings) and postgraduate alumni (26.4% currently employed in research, 19.5% in clinical settings). The main pathways for finding jobs were by direct search (38.6%), completing tertiary education (29.2%), and through social network connections (16.4%). Women alumni were less likely to feel that Anatomy prepared them for their careers than men. Themes related to positive and negative experiences included staff, course material/resources, social events, and peers. Suggestions to improve the departmental "sense of community" included increasing departmental events and resources. Alumni suggested that Anatomy should provide more potential career information, make available recent alumni profiles, and organize career fairs and networking opportunities. Postgraduate alumni were more likely to feel a "sense of belonging" in Anatomy than undergraduate alumni. Findings from this research provide an essential data point in the international evaluation of career prospects of anatomy graduates and provide a road map for other institutions to survey their alumni to obtain local insights.

Scales for Assessing Male Sexual Function are not Entirely Applicable to Gay and Bisexual Men with Prostate Cancer.

Scales designed for assessing male sexual function may not be suitable for men of all sexual orientations. We reviewed frequently used sexual function scales and examined the item content and documentation of validation. These scales predominantly focus on general sexual function and erection. They lack questions on behaviors relevant to men-who-have-sex-with-men (MSM), such as anal sex, masturbation, or sexual activities outside of committed relationships. Additionally, the validation samples rarely mention inclusion of MSM, revealing a clear gap in the clinical evaluation tools available for MSM, who are experiencing sexual dysfunction from prostate cancer treatment side effects.
