Randomized, double blind, placebo controlled clinical study to assess efficacy and safety of NRL/MW/201901 in subjects suffering from erectile dysfunction

Sex is an integral part of a well-being. Sexual satisfaction is the most important component of the quality of life. In management of ED overall sexual potential and quality of life needs to be taken care of as a holistic approach to management. The aim of the study was to clinically validate effect of NRL/MW/201901 a polyhedral Nutraceutical product in ED. The clinical efficacy of NRL/MW/201901 in patients suffering from erectile dysfunction was evaluated by assessing Quality of Erection Questionnaire and sexual encounter profile with Intra-vaginal ejaculation latency time, serum testosterone and anthropometric analysis etc. NRL/MW/201901 was effective in increasing erection function, orgasmic function, intercourse satisfaction, overall satisfaction and sexual desire. There is marked increase in number of sexual encounters in NRL/MW/201901 treated group. Serum levels of testosterone were increased after treatment of NRL/MW/201901 than in placebo group. It was evident from the anthropometric analysis of the subjects that there was significant increase in resting metabolism and % skeletal muscle content in NRL/MW/201901 treated group. There were no evident adverse events related to drug. Thus it could be concluded that NRL/MW/201901 is safe and effective in the treatment of mild to moderate erectile dysfunction.

Proven prevention tools for addressing STI epidemics

The ongoing rise of sexually transmitted infections (STIs) poses a global public health challenge and the risk of acquiring one of these infections depends upon sexual practices, the number of sexual encounters and the location of that individual within the sexual network. Commercial sex workers (CSWs) have potentially a pivotal role in the transmission of STIs; however, a new study presented in this journal describes markers of risk but no increase in infections amongst men who pay for sex (MPS). This commentary highlights some of the growing evidence regarding STI prevention and the value of using these tools to protect CSWs, their clients and by extension the sexual partners of MPS.

Influence of Progesterone on Sexual Performance in Male Rats

It has been documented that copulatory experience can alter or improve sexual performance in male rats. However, the hormonal basis and the number of sexual encounters needed for a rat to acquire sufficient performance remains unclear. The aim of this study was to examine whether levels of testosterone and progesterone are associated with sexual performance in male rats. Adult male Wistar Hannover rats were exposed to a receptive female for 15 minutes every other day for 9 days for acquiring sexual experience. After training protocol, rats were scored as low or high sexual performers. Hormonal levels (testosterone and progesterone) were evaluated in both trained and non-trained control groups. Our results showed that a 9-day training period was not sufficient for some male rats to acquire a good level of sexual performance. While 42.5% of the rats displayed excellent sexual performance during the training sessions, 17.5% showed adequate performance, 7.5% had low sexual activity, and 32.5% of the rats did not display any sexual behaviors whatsoever. Additionally, after 4 days of training, rats with excellent/adequate performance showed a significant decrease in ejaculation latency relative to the first day of training. The rats with low or no sexual activity had lower progesterone levels relative to those displaying the highest sexual performance after 9 days of training. Testosterone, in turn, was also significantly reduced in animals with low/no sexual performance compared with excellent/adequate rats. In conclusion, progesterone may be a limiting factor to promoting sexual performance in male rats.

Australian men's sexual practices in saunas, sex clubs and other male sex on premises venues

Sex on premises venues (SOPVs) where men have sex with men have been implicated in the spread of sexually transmissible infections, but few studies have described men's sexual encounters in SOPVs, particularly the degree to which men from different backgrounds engage in risky sexual practices. Interviewer administered surveys were conducted with 186 Australian men who have sex with men (MSM) within 48 h of visiting an SOPV. They reported their sexual practices, the characteristics of their partners and other circumstances surrounding their sexual encounters. All analyses were based on the number of sexual encounters (n = 430). Oral sex was the most common practice, occurring in 74.9% of encounters, followed by massage, frottage or kissing (53.7%), solo or mutual masturbation (36.3%), and anal sex (32.1%). Multivariate analyses revealed age as a significant factor for having protected anal sex (P = 0.001), insertive anal sex (P = 0.004) and receptive anal sex (P < 0.001). These practices were more frequent in encounters among younger men, while masturbation (P = 0.03) was more frequent among older men. When men's sexual partners were affected by alcohol, encounters were less likely to involve unprotected anal intercourse (P = 0.006) and more likely to involve massage, frottage or kissing (P = 0.009). Men disclosed their HIV status in only 7.7% of encounters. With the likelihood of risky sexual practices varying according to background, results from this study should be used to guide interventions aiming to promote safer sex in SOPVs.

Two core group models for sexual transmission of disease

Models for sexually transmitted disease generally assume that the influence of all individuals is identical in the spread of disease during the period of infection. In this paper, two disease transmission models, which depend on the core group (the group of individuals who are sexually very active) are examined. In the first model, the core group is a subpopulation of susceptibles and in the second model, the core group is a subpopulation of infectives. It is assumed that each core individual comes into sexual contact with an average number of other individuals per unit time. For each model the threshold conditions for an endemic infection are determined. The stability at the uninfected state and the prevalence at the infected state are investigated. The results show that the transmission dynamics of epidemic disease is critically dependent on the effects of small subpopulations with varying levels of sexual activity. Therefore, the average number of sexual encounters of the core group can play an important role in the spread of disease.

Bacterial vaginosis and HIV seroprevalence among female commercial sex workers in Chiang Mai, Thailand

To investigate the relationship between HIV seropositivity and bacterial vaginosis (BV) in a population at high risk for sexual acquisition of HIV. A cross-sectional study was conducted among 144 female commercial sex workers in Chiang Mai, Thailand. The participants were tested for cervical gonorrhea and Chlamydia infection, syphilis, Trichomonas vaginitis, Candida vaginitis, BV, and HIV infection. BV was diagnosed by clinical criteria (pH > 4.5, positive amine test, and presence of clue cells) and using Gram stains. Thirty-three per cent of participants had BV, and 43% were HIV-positive. Using clinical criteria, the association of BV and HIV seropositivity was significant [odds ratio (OR), 2.7; 95% confidence interval (CI), 1.3-5.0]. Although the association between BV and HIV prevalence was not significant using Gram stains alone for diagnosis of BV, an association was found between abnormal vaginal flora and HIV (OR, 2.1; 95% CI, 1.0-4.8). In multiple logistic regression analysis, adjusting for age, number of sexual encounters per week, current condom use, and currently having a sexually transmitted disease (STD), both BV and a history of an STD were independently associated with HIV seropositivity (adjusted OR for BV, 4.0 and 95% CI, 1.7-9.4; adjusted OR for history of an STD, 6.9 and 95% CI, 2.1-22.9). When diagnosed clinically, BV is independently associated with HIV seroprevalence. HIV infection may promote abnormal vaginal flora, or BV may increase susceptibility to sexual transmission of HIV. Alternatively, the association seen here may result from intervening variables; in this case BV may be a marker or a cofactor of HIV transmission.

Heterosexual partnership characteristics of university women.

In order to assess the individual risk of acquiring sexually transmitted diseases (STDs), both characteristics of the partnership and the individual should be considered. Partnership characteristics have been used as risk markers for STD transmission but their distribution has not been well described. Using a self-administered questionnaire, we collected information on the partnership characteristics of the 4 most recent sexual partners of the members of 9 university women's social organizations at the University of Michigan. Respondents were asked to report the setting of the first meeting of partners, the length of the presexual relationship, condom use at the first sexual encounter and the total number of sexual encounters within that partnership. We graphically analyse changes in these partnership characteristics with respect to partnership order. As the number of sexual partners increased the women in this population were more likely to report partnership characteristics associated with an increased risk of acquiring an STD. In addition, partnership characteristics varied with the order of the partnership, implying that no single partnership is representative of all others.

Sexually Transmitted Diseases In Homosexual Men

Due to the number of sexual encounters and variety of practices, men who have homosexual experiences have increased incidence and prevalence rates of many diseases. Diseases that are covered here include hepatitis A and B, syphilis, gonorrhea, condylomata accuminata, herpes simplex, AIDS (acquired immune-deficiency syndrome) and several enteric diseases, namely amebiasis, giardiasis, shigellosis and salmonellosis. An overview of each disease is included along with diagnostic testing and treatment regimens. This report concludes with a system of risk assignment and recommendations for frequency of sexually transmitted disease screening.
