Erectile function in circumcised and uncircumcised men in Lusaka, Zambia: A cross-sectional study

Responses of Five Different Artificial Intelligence Chatbots to the Top Searched Queries About Erectile Dysfunction: A Comparative Analysis

The aim of the study is to evaluate and compare the quality and readability of responses generated by five different artificial intelligence (AI) chatbots-ChatGPT, Bard, Bing, Ernie, and Copilot-to the top searched queries of erectile dysfunction (ED). Google Trends was used to identify ED-related relevant phrases. Each AI chatbot received a specific sequence of 25 frequently searched terms as input. Responses were evaluated using DISCERN, Ensuring Quality Information for Patients (EQIP), and Flesch-Kincaid Grade Level (FKGL) and Reading Ease (FKRE) metrics. The top three most frequently searched phrases were "erectile dysfunction cause", "how to erectile dysfunction," and "erectile dysfunction treatment." Zimbabwe, Zambia, and Ghana exhibited the highest level of interest in ED. None of the AI chatbots achieved the necessary degree of readability. However, Bard exhibited significantly higher FKRE and FKGL ratings (p = 0.001), and Copilot achieved better EQIP and DISCERN ratings than the other chatbots (p = 0.001). Bard exhibited the simplest linguistic framework and posed the least challenge in terms of readability and comprehension, and Copilot's text quality on ED was superior to the other chatbots. As new chatbots are introduced, their understandability and text quality increase, providing better guidance to patients.

Male Circumcision Due to Phimosis as the Procedure That Is Not Only Relieving Clinical Symptoms of Phimosis But Also Improves the Quality of Sexual Life

INTRODUCTION

Male circumcision is recognized as the most effective method of phimosis treatment. Analyzing the literature, the information about the influence of male circumcision due to phimosis for patients' subjective symptoms such as itching, burning, penile pain, pain during intercourse, and quality of sexual life is insufficient.

AIM

To investigate the effect of male circumcision due to phimosis to patients' subjective symptoms, including erectile function and satisfaction with their genitals.

METHODS

The single-center prospective study began in January 2018 and ended in January 2020. Sixty-nine male, adult patients, who were qualified for circumcision due to phimosis, were included in the study.

MAIN OUTCOMES MEASURES

The study outcomes were obtained using questionnaires such as visual analog scale 0-10 for itching, burning, penile pain, and penile pain during intercourse; International Index of Erectile Function (IIEF-5) and Male Genital Self Image Scale 7 (MGSIS-7) to assess the changes in patients sexual functioning.

RESULTS

Before the circumcision of the 69 patients included in the study, 59 patients (86%) reported some subjective symptoms of phimosis. The most frequent and most severe complaint was pain during intercourse, then itching and burning of the penis. Penile pain at rest was the least frequent. After 3 months from circumcision, subjective symptoms almost completely disappeared. All of 69 patients declared to have a sexual partner. 3 months after circumcision, all patients achieved significant improvement in both obtaining and maintaining an erection based on IIEF-5 score. Their sexual intercourse was more satisfying for them. All patients suffering from phimosis were embarrassed about their genitals before surgery. 3 months after circumcision, satisfaction with genital self-image increased significantly.

CONCLUSION

Male circumcision due to phimosis is not only relieving the clinical symptoms of phimosis, but it also improves the quality of sexual life. Czajkowski M, Czajkowska K, Zarańska K, et al.

The Contrasting Evidence Concerning the Effect of Male Circumcision on Sexual Function, Sensation, and Pleasure: A Systematic Review

INTRODUCTION

Active debate concerns whether male circumcision (MC) affects sexual function, penile sensation, or sexual pleasure.

AIM

To perform a systematic review examining the effect of MC on these parameters.

METHODS

PRISMA-compliant searches of PubMed, EMBASE, the Cochrane Library, and Google Scholar were performed, with "circumcision" used together with appropriate search terms. Articles meeting the inclusion criteria were rated for quality by the Scottish Intercollegiate Guidelines Network system.

MAIN OUTCOME MEASURE

Evidence rated by quality.

RESULTS

Searches identified 46 publications containing original data, as well as 4 systematic reviews (2 with meta-analyses), plus 29 critiques of various studies and 15 author replies, which together comprised a total of 94 publications. There was overall consistency in conclusions arising from high- and moderate-quality survey data in randomized clinical trials, systematic reviews and meta-analyses, physiological studies, large longitudinal studies, and cohort studies in diverse populations. Those studies found MC has no or minimal adverse effect on sexual function, sensation, or pleasure, with some finding improvements. A consensus from physiological and histological studies was that the glans and underside of the shaft, not the foreskin, are involved in neurological pathways mediating erogenous sensation. In contrast to the higher quality evidence, data supporting adverse effects of MC on function, sensation, or pleasure were found to be of low quality, as explained in critiques of those studies.

CONCLUSION

The consensus of the highest quality literature is that MC has minimal or no adverse effect, and in some studies, it has benefits on sexual functions, sensation, satisfaction, and pleasure for males circumcised neonatally or in adulthood.

Medical Male Circumcision Is Associated With Improvements in Pain During Intercourse and Sexual Satisfaction in Kenya

Background

Two cohort studies using data from randomized controlled trials in Africa offer the best evidence to date on the effects of voluntary medical male circumcision (VMMC) on male sexual function and satisfaction, suggesting no significant impairments in sexual function or satisfaction and some improvements in sexual function after male circumcision.

Aim

To assess the effects of VMMC on sexual function and satisfaction in a large population-based cohort of men circumcised as adults and uncircumcised controls in Kenya.

Methods

Sexual function and satisfaction of young (median age = 20 years) sexually active men (1,509 newly circumcised men and 1,524 age-matched uncircumcised controls after 5% loss to follow-up) were assessed at baseline and 6, 12, 18, and 24 months, with data collected in 2008 to 2012. Self-reported data on lack of sexual interest or pleasure, difficulty getting or maintaining erections, orgasm difficulties, premature ejaculation, pain during intercourse, and satisfaction with sexual intercourse were analyzed with mixed-effect models to detect differences between circumcised and uncircumcised men and changes over time.

Outcomes

Changes over time in sexual interest, desire and pleasure, erectile and ejaculatory function, and pain during intercourse (dyspareunia) in circumcised and uncircumcised men; group differences in time trends; satisfaction with sexual performance; and enjoyment of sex before and after circumcision.

Results

Sexual dysfunctions decreased in the two study groups from 17% to 54% at baseline to 11% to 44% at 24 months (P < .001), except dyspareunia, which decreased only in circumcised men (P < .001). Sexual satisfaction outcomes increased in the two study groups from 34% to 82% at baseline to 66% to 93% at 24 months (P < .001), with greater improvements in circumcised men (P < .001). On average, 97% of circumcised men were satisfied with sexual intercourse and 92% rated sex as more enjoyable or no different after circumcision compared with before circumcision.

Clinical Translation

Results are applicable to VMMC programs seeking to increase the acceptability of male circumcision as part of comprehensive HIV prevention.

Strengths and Limitations

Large-scale population-based longitudinal data restricted to sexually active individuals and adjusted for differences in baseline levels of outcomes and potential confounders are used. The questionnaire used, although not a standardized survey instrument, includes all major domains of male sexual function and satisfaction used in the most common standardized tools.

Conclusions

Results are consistent with large cohort studies of VMMC using data from randomized controlled trials and indicate that VMMC has no significant detrimental effect or might have beneficial effects on male sexual function and satisfaction for the great majority of men circumcised as adults.

Circumcision and its effects in Africa

Male circumcision is one of the most commonly performed procedures in Africa, with a wide variation between the different regions on the practice. This is because circumcision is often done for religious and cultural or traditional reasons, which includes being part of rituals or rite of passage to adulthood. There had been few medical indications for the procedure until the human immunodeficiency virus (HIV)/acquired immune deficiency syndrome (AIDS) pandemic, which is prevalent in many of the countries in the region. Evidence from randomized controlled trials conducted in the continent had shown that male circumcision could be instrumental to reducing the transmission of HIV/AIDS in heterosexual couples in high disease prevalent and low circumcision prevalent areas. This had led to the roll-out of large population-based adult male circumcisions as well as the development of tools to facilitate the procedure. Circumcision, however, is not without complications and the incidence appears related to the age of the patient, where the procedure was done, technique used and level of proficiency of the practitioners. This article reviews the practice of circumcision in Africa and highlights the impact of the procedure on the continent.
