Epidemiology of Male Sexual Dysfunction (MSD) in Patients Consulting in Some Health Services in the City of Douala, Cameroon

Sexual dysfunction is a group of diseases, disorders or difficulties experienced by men or women during any stage of normal sexual activity. In Africa in general and Cameroon in particular, statistical data concerning the prevelance and the main causes of male sexual dysfunction are rare due to socio-cultural and religious burdens and sometimes self-medication. The objective of this work was to determine the prevalences, comorbidities and the risk factors of the main sexual dysfunction in some hospitals in city of Douala. Through a descriptive retrospective study carried out from Novembre 2019 to June 2021, sociodemographic parameter, reasons of consultation, risk factors and type of male sexual dysfunction (erectile dysfunction or erectile dysfunction (ED), ejaculation disorders (EjD), libido disorders (LD) and disorders of sexual activity with pain or painful sexual intercourse (PSI)) were collected in the medical files of patients who have made urological consultation between 2016 and 2020 at the Deido District hospital, Laquintinie Douala Hospital and Douala General hospital respectively. At the end of our data collection, out of a total of 24995 consultations, 2743 (10.98%) patients were suffering from at least one male sexual dysfunction. Moreover, sexual disorders were the 2nd reason of urological consultation (13.69%) after urinary disorders (33.85%). Among sexual disorders, erectile (76%) and ejaculatory (20%) disorders were the predominant pathologies recorded with the prevalences of 9.79 et 2.62% respectively, and were mostly represented in patients from [41 - 50] for erectile dysfunction, and [18 - 30] years old for ejaculative dysfunction. In addition, the number of patients with ejaculatory and erectile dysfunctions was more important in patients from [18 - 30] and [31 - 40] years old respectively. Among patients presenting sexual disorders, several risk factors or pathologies were associated with the dysfunction: benign prostatic hyperplasia and metabolic syndrome (in patients over 50 years old);psychosocial problems, infections, and alcohol (in patients under 50 years old). These findings could be useful in the elaboration of therapeutic strategies for the management of the Cameroonian population suffering from sexual dysfunctions.

Erectile dysfunction in nonmuscle-invasive bladder cancer patients before and after transurethral resection(TUR)of bladder tumor in China

The aim of this study was to investigate the incidence of erectile dysfunction(ED)in nonmuscle-invasive bladder cancer(NMIBC)patients before and after transurethral resection(TUR)in China.Clinical data from 165 male patients with NMIBC who received adjuvant intravesical chemotherapy after TUR in Neijiang First People’s Hospital(Neijiang,China)between January 2010 and June 2019 were retrospectively reviewed.The sexual function of these patients was evaluated before and 1.5 years after initial TUR by the International Index of Erectile Function-5(IIEF-5).An age-specific subanalysis was performed among the patients:<45 years old(Group 1,n=19)and≥45 years old(Group 2,n=146).Before and 1.5 years after TUR,the incidence rates of ED in Group 1 were 15.8%and 52.6%,and those in Group 2 were 54.1%and 61.0%,respectively.The difference between groups was statistically significant at the preoperative stage(15.8%vs 54.1%,P=0.002)but not at the postoperative stage(52.6%vs 61.0%,P=0.562).Compared with the preoperative stage,the incidence of ED at the postoperative stage was increased significantly in Group 1(15.8%vs 52.6%,P=0.017)but not in Group 2(54.1%vs 61.0%,P=0.345).In conclusion,the incidence of ED increased in male NMIBC patients under the age of 45 years after TUR in China.These patients should be offered professional counseling during the follow-up period.

Shaping the future of men's sexual health:How artificial intelligence can assist in the management and treatment of erectile dysfunction

Artificial intelligence(AI)is a complex combination of multidisciplinary machines and systems that can replicate human-like cognitive tasks to execute capabilities such as pattern recognition,decision-making,and problem-solving.Dating back to the 2000s,AI has been utilized in the medical field,however the interest in this subject has sharply increased over the past several years.Erectile dysfunction(ED)is an increasingly pervasive issue as men age,affecting up to 150 million men worldwide.In the field of men's health,AI has been employed to assist physicians in the evaluation and management of ED.This article aims to summarize the ways in which AI has been utilized in the management of ED,as well as the considerations that must be made when implementing this technology.AI can be utilized for virtual health assistance to protect patient privacy and increase access to care.Augmented reality can aid surgeons in real-time during operations,as well as be utilized to prepare physicians for situations that they may encounter in the operating room.Pharmaceutical companies can benefit from AI in the interpretation of data,analysis of chemical compounds and in drug development.Additionally,AI can be used to assist patients in post-procedure recovery in the form of rehabilitation and post-treatment monitoring.While the utilization of AI in men's health is an exciting venture,there are tremendous ethical and practical considerations that have limited its use in the management of ED.

Validity of premature ejaculation diagnostic tool and its association with International Index of Erectile Function-15 in Chinese men with evidence-based-defined premature ejaculation

The premature ejaculation diagnostic tool （PEDT） is a brief diagnostic measure to assess premature ejaculation （PE）. However, there is insufficient evidence regarding its validity in the new evidence-based-defined PE. This study was performed to evaluate the validity of PEDT and its association with IIEF-15 in different types of evidence-based-defined PE. From June 2015 to January 2016, a total of 260 men complaining of PE and defined as lifelong PE （LPE）/acquired PE （APE） according to the evidence-based definition from Andrology Clinic of the First Affiliated Hospital of Anhui Medical University, along with 104 male healthy controls without PE from a medical examination center, were enrolled in this study. All individuals completed questionnaires including demographics, medical and sexual history, as well as PEDT and IIEF-15. After statistical analysis, it was found that men with PE reported higher PEDT scores （14.28 ± 3.05） and lower IIEF-15 （41.26 ± 8.20） than men without PE （PEDT： 5.32 ± 3.42, IIEF-15：52.66 ± 6.86, P 〈 0.001 for both）. It was suggested that a score of 〉9 indicated PE in both LPE and APE by sensitivity and specificity analyses （sensitivity： 0.875, 0.913; specificity： 0.865, 0.865, respectively）. In addition, IIEF-15 were higher in men with LPE （42.64 ± 8.11） than APE （39.43 ± 7.84, P 〈 0.001）. After adjusting for age, IIEF-15 was negatively related to PEDT in men with LPE （adjust r = -0.225, P 〈 0.001） and APE （adjust r = -0.378, P 〈 0.001）. In this study, we concluded that PEDT was valid in the diagnosis of evidenced-based-defined PE. Furthermore, IIEF-15 was negatively related to PEDT in men with different types of PE.
