Objective: To investigate the population size of transgender women (TGW) in Tianjin and analyze the characteristics of their sexual behaviors to provide a basis for AIDS prevention and control. Methods: To estimate the population size of TGW in Tianjin using the capture-recapture method. At the same time, an anonymous questionnaire was collected to conduct a multi-factor logistic analysis of the TGW population's sexual behavior. Results: A total of 213 TGW were investigated. Tianjin's estimated TGW population size was 599 (95%CI: 407-792). Multivariate logistic analysis of the use of condoms consistently showed that compared with TGW without regular sex partners, those with regular sex partners had a lower proportion of consistent condom use (aOR=0.44, 95%CI: 0.23-0.82) and had received HIV tests in the last year were more likely to adhere to condom use than those who had not been tested (aOR=2.73, 95%CI: 1.06-6.99). Conclusion: It is necessary to strengthen HIV mobilization testing among the TGW population and their regular sexual partners to improve condom use.

Objective To investigate the rate and correlates of receiving human immunodeficiency virus(HIV) serostatus disclosure from their most recent male sexual partners among men who have sex with men(MSM) aged 50 and above. Methods With a geosocial networking application,we recruited participants through online convenience sampling to collect the demographic variables,behavioral information,receiving HIV serostatus disclosure,etc.Univariate and multivariate analyses were performed to interpret the associated factors of receiving HIV serostatus disclosure. Results Overall,38.4%(398/1037) of participants received HIV serostatus disclosure from their most recent male sexual partners.The multivariable analysis demonstrated that the following populations were less likely to receive HIV serostatus disclosure from their most recent male sexual partners:participants with junior high school degree or below(OR=0.660,95%CI=0.473-0.922, P=0.015) compared to those with senior high school degree or above;participants unemployed(OR=0.537,95%CI=0.322-0.896, P=0.017) and employed(OR=0.663,95%CI=0.466-0.944, P=0.022) compared to those retired;participants without knowledge about HIV or acquired immune deficiency syndrome(AIDS) compared to those with knowledge about HIV/AIDS(OR=0.636,95%CI=0.466-0.868, P=0.004);participants having ≥2 male sexual partners in the last year(OR=0.433,95%CI=0.320-0.586, P<0.001) compared to those having none or one male sexual partner;participants never been tested for HIV(OR=0.544,95%CI=0.403-0.734, P<0.001) compared to those ever been tested for HIV;participants ever been diagnosed to have sexually transmitted infection(STI)(OR=0.472,95%CI=0.349-0.637, P<0.001) compared to those never diagnosed to have STI;and participants with higher level of HIV stigma(OR=0.742,95%CI=0.604-0.912, P=0.005). Conclusions Our findings indicated that the MSM aged 50 and above had low possibility of receiving HIV serostatus disclosure from the most recent male sexual partners.Education,employment status,number of sexual partners,HIV/AIDS-related knowledge,HIV testing behaviors,STI infection history,and HIV stigma contributed to this result.

OBJECTIVES: The epidemic of acquired immune deficiency syndrome (AIDS) among men who have sex with men (MSM) is severe in China. And MSM has now become a key population for the infection and transmission of AIDS. At present, the bottleneck of AIDS prevention and control among MSM population is low rate of continuous condom use and high incidence of unsafe sexual behavior. Inductive summarization of the literature revealed that the most critical reason for low rate of continuous condom use among the MSM population was condom-related stigma. Although many studies mentioned condom-related stigma among MSM populations, there has been no any definition of MSM-related condom stigma and no measurement for it. Therefore, the paper aims to explore barriers to condom use among MSM, then construct the conceptual and operational definition of "MSM-related condom stigma" through Meta synthesis and concept synthesis, and provide a new perspective for AIDS prevention and control among MSM. METHODS: Based on evidence-based method, "PICoS" framework and Meta-synthesis was used to include the literatures. Then, we used synthesized qualitative evidence from included studies to construct the concept and operational definition of MSM-related condom stigma by the means of thematic analysis and concept synthesis. RESULTS: According to the results of the concept synthesis, MSM-related condom stigma refers to any taboos or misbeliefs about condom use or feeling ashamed or embarrassed to talk about using condoms which perceived by individuals at the individual, interpersonal, and social levels.It was demonstrated through 4 sub-themes at operational level: a symbol of distrust, a symbol of HIV/sexual transmitted infections (STIs) prevention, a symbol of an embarrassing topic, and a symbol of violating the traditional cognition of sexual intercourse. According to the Social-ecological Model (SEM), a symbol of distrust refers to that the MSM population believes that not using condoms represents mutual trust between sexual partners, while using condoms is difficult to express intimacy, trust and loyalty between sexual partners. A symbol of HIV/STIs prevention at the interpersonal level refers to that the MSM population believes that condom use is a "symbol" for the prevention or infection of AIDS; on the one hand, if someone proposes to use condoms, he may be considered infected with HIV or have unsafe sex experiences, thus, making it difficult to propose condom use; on the other hand, if they believe that sexual partners are "AIDS free" (often a wrong perception, such as sexual partners may have the risk of AIDS infection although they do not have AIDS), it is considered that condom use is completely unnecessary. The environmental level includes a symbol of an embarrassing topic and a symbol of violating the traditional cognition of sexual intercourse. A symbol of an embarrassing topic refers to the MSM population feels shame about topics related to sexual behavior and is embarrassed to carry/buy/propose condom use or be ashamed to engage in conversations about whether to use condoms during sexual behavior. And a symbol of violating the traditional cognition of sexual intercourse: The MSM population have limitations in their perception of "sex" or "sexual behavior" and believe that real sex (behavior) is unobstructed contact between the bodies and exchange between all body fluids. CONCLUSIONS The concept of MSM-related condom stigma is proposed for the first time, and its operational definition is given. The concept includes 3 levels and 4 dimensions. It is helpful to understand MSM people's attitude and cognition towards condoms, and adds indicators with cultural sensitivity and behavioral sensitivity to the behavioral intervention for AIDS in the future.

Objective: To identify the status and determinants of sharing personal HIV information with sexual partners among men who have sex with men (MSM) meeting their casual sexual partners on the internet. Methods: A cross-sectional study was conducted in five cities (Hangzhou, Ningbo, Wenzhou, Taizhou and Shaoxing) in Zhejiang province. The recruitment was enrolled by MSM social organization and in voluntary counseling and testing clinics, with a sample size of 793. A self-designed network questionnaire collected essential characteristics, HIV knowledge, sexual behavior, and sharing personal HIV status. SPSS 20.0 software was used for statistical analysis. Results: Among 767 MSM enrolled 302 MSM who reported finding casual sexual partners on the internet were enrolled in the analysis. MSM reported finding casual partners on the internet only, finding sexual partners online and in places were 62.6% (189/302) and 37.4% (113/302), respectively. Among those reporting web-based sexual behavior in the last six months, 54.6% (165/302) informed their partners of their HIV status, 49.2% (146/297) inquired about HIV status, and 42.9% (82/191) knew HIV status before sex intercourse, 75.8% (113/149) reported consistent condom use with HIV negative partners. The multivariable logistic regression analysis showed that related factors of inconsistent inquired HIV status of partners included 25-34 years old (aOR=2.17, 95%CI: 1.20-3.91), >2 partners on the internet in the last six months (aOR=2.13, 95%CI: 1.27-3.57), low-risk perception of HIV infection with online partners (aOR=1.96, 95%CI:1.14-3.35), numbers of HIV testing >1 times (aOR=0.38, 95%CI: 0.22-0.66). Conclusions: The willingness to know the HIV status of partners among MSM who met sexual partners on the internet was high but with a low rate of knowing their sex partner's HIV status in Zhejiang province. However, the successful implementation proportion was low. Therefore, it is necessary to pay attention to people who are elderly, with less conscience about the risk of the sex partners on the internet, have more sex partners, and have received few HIV tests. In addition, peer education was needed to promote related intervention programs.

OBJECTIVES: To explore the Impact of community subculture of men who have sex with men (MSM) on the occurrence of high-risk sexual behavior based on the health belief model. METHODS: A qualitative research method was used to conduct in-depth interviews with 17 MSM by one-to-one and half-structured way, and thematic analysis was used to analyze the data. RESULTS: There were several factors for high-risk sexual behavior in MSM subculture, such as trust, subjective assessment for partner or personal health status, the role in inserting, awareness of HIV infection among partners, perception of HIV and homosexual discrimination, difficulty in maintaining a fixed partner, family responsibility,and so on. Self-efficacy also affected MSM's high-risk sexual behavior. CONCLUSIONS High-risk sexual behavior in MSM population is influenced by individual, group, and intra-circle subculture. Cognitive bias for HIV infection in MSMs can be intervened by constructing a preventive intervention model for high-risk sexual behavior.

Background: Sexuality remains to be a sensitive issue in the Philippines, but it encompasses real problems that stroke patients and their partners continue to face. Sexual dysfunction, an under-recognized complication post-stroke, is caused by an interplay of physical, emotional, cognitive, and language impairments, in combination with psychosocial factors. Objectives: This study aimed to determine changes in sexual functioning (libido, coital frequency, sexual arousal, and sexual satisfaction) among stroke out-patients at the Philippine General Hospital and their sexual partners. Methods: This cross-sectional study involved patients (≥30 years old with 1 stroke episode), and their partners. Through individual interviews and questionnaires, data were gathered on general attitude toward sex, ability to address sexual issues with partner, fear of recurrence of stroke, unwillingness to participate in coitus, risk of depression, and level of happiness. Results: Twenty-nine patients and 23 partners participated. There was a statistically significant decrease in coital frequency post-stroke among patients (p<0.001) and partners (p<0.05). Majority reported lower level of libido, sexual arousal, and sexual satisfaction post-stroke. Participants unable to discuss sexual issues with partner were more likely to report sexual dissatisfaction (p<0.05). Those with higher scores on Zung’s depression scale were likely to be sexually dissatisfied (p<0.05). Level of happiness was moderately correlated with sexual satisfaction (r=0.51). Conclusion Sexual life of couples affected by stroke is commonly overlooked. There was a decline in libido, coital frequency, arousal, and sexual satisfaction among stroke patients and partners at the Philippine General Hospital.

PURPOSE: Although the prevalence of erectile dysfunction (ED) can be affected by social changes, this association has not been well evaluated. We aimed to evaluate the prevalence and risk factors of ED through a 10-year-interval web-based survey using the previous database of same group of panels, with same methodology. MATERIALS AND METHODS: We sent e-mails and surveyed the panels registered in the Internet survey agency. RESULTS: In total, 900 participants were recruited in 2016. The age-adjusted overall prevalences of self-reported ED (self-ED) and International Index of Erectile Function-5-assessed ED (IIEF-5-ED; score ≤21) in the 2016 study were 3.2% and 44.8%, respectively, which were lower than the prevalences of 8.1% (p=0.036) and 51.4% (p=0.323), respectively, in the 2006 study. The risk factors of IIEF-5-ED in their 20s and 30s in 2016 were psycho-social factors such as depression, low frequency of conversation about sex with sexual partner. The risk factors of IIEF-5-ED in their 40s to 60s in 2016 were organic factors, such as hypertension, diabetes mellitus, smoking, alcohol use, and self-reported premature ejaculation. CONCLUSIONS: Although the age-adjusted overall prevalence of self-ED has decreased during a decade, there was no difference in the age-adjusted overall prevalence of IIEF-5-ED. Psycho-social support may be important for young men with ED and overall healthcare can be helpful for elderly men with ED.

The increase in life expectancy has caused attention to be focused on quality of life in the elderly. Sexual health is an important part of physical health and quality of life, and poor health is associated with both a decline in sexual activity with age and sexual dysfunction. Herein, we review the topics of sexual function, sexual activity, the prevalence rate of sexual dysfunction and its risk factors, changes in sexuality-related attitudes, the relationship between sexual health and physical health, and the effects of sexual health on quality of life in the elderly. Sexual activity is associated with physical health, and is also an important component of enjoying life. Sexual activities include sexual intercourse and physical intimacy, which are indicators of sexual health in the elderly. Good physical health, stable sexual partners, and regular sexual activity are important for maintaining sexual health in old age Therefore, sexual health needs to be considered as part of the management of geriatric patients.

ObjectiveHuman papilloma virus (HPV) is a necessary cause of cervical cancer and is also closely related to penile cancer, oropharyngeal cancer, and anal cancer in males. However, few studies are reported on male HPV. This study aimed to investigate HPV infection of the external genitalia in men whose female partners have cervical HPV infection.

METHODSWe collected the relevant data on the male outpatients whose partners had cervical HPV infection in our Department of Urology and Andrology from August to December 2016. We obtained samples with nylon swabs from the glans penis, corona, inner layer of the prepuce and penile body and detected different types of HPV infection using the Hybribio HPV typing kit, PCR and membrane hybridization.

RESULTSValid data were collected from 140 males, which showed 83.5% of HPV infection of the external genitalia, including 60 cases of HPV6 (43.2%), 27 cases of HPV16 (19.4%), 14 cases of HPV39 (10.1%), 13 cases of HPV18 (9.4%), 13 cases of HPV58 (9.4%), and 13 cases of HPV52 (9.4%). Redundant prepuce was found in 75.5% of the males, but there was no statistically significant difference in the incidence rate of HPV infection between the normal and redundant prepuce groups (P > 0.05).

CONCLUSIONSMen who have the female partners with positive cervical HPV are at high risk of HPV infection and therefore need to be screened and treated so as to reduce HPV infection in both sexes.

Premature ejaculation (PE) is a most common type of ejaculatory dysfunction, which has significant adverse effects on the life quality of the patients and their partners. Medication is currently the first choice for PE and psycho-behavior therapy is sometimes used as an adjuvant means. It is reported in a number of studies that medication alone or combined with psycho-behavior therapy has a great short-term efficacy and a very low risk of side effects. Conservative therapies for PE, however, have some obvious disadvantages such as easy recurrence after drug withdrawal, ineffectiveness in some cases, and so on. Thus, clinicians in China and abroad have developed and tried various surgical methods for the treatment of PE, most of which are reportedly safe and effective. However, International Society for Sexual Medicine guidelines for the diagnosis and treatment of PE recommended against surgical methods because of possible permanent loss of sexual function and insufficient reliable data, though without support from evidence or relevant literature. Although controversial, surgical treatment remains an effective and feasible strategy for refractory PE that does not respond to any conservative therapies. This review summarizes a variety of surgical techniques for PE, along with their basic principles, indications, effects and safety.
