Erectile Dysfunction among People Who Use Ketamine and Poly-Drugs

A non-latex condom has no influence on male physiological sexual arousal

Background/Objective

Men do not use external condoms for several reasons, which can result in public health problems. One of these is related to Condom-Associated Erectile Problems. This study aimed to examine the sexual arousal response of heterosexual men when using an external condom made of synthetic resin type AT-10.

Method

A total of 82 Colombian young men (Mage = 23.17 years, SD = 3.04, age range = 18-30) participated in this experimental study. Two random groups (experimental and control; n = 41 each) were compared. The experimental group used condoms, whereas the control group did not. Fit and feel condom perceptions, initial erectile scores, age, and substance use were controlled for. Erection was measured while viewing a sexual video by using penile plethysmography and subjective arousal.

Results

The results, obtained from comparing the experimental group (using pre-erection condoms) with the control group (not using condoms), revealed no significant difference in both subjective and physiological sexual arousal. This suggests that pre-erection condoms do not have an effect on the erectile response.

Discussion

More research is needed in this area to provide treatment and clinical interventions or sexual and reproductive education to mitigate the occurrence of sexual dysfunction, unplanned pregnancies, or sexually transmitted infections. Also, research addresses public health issues related to the prevention and/or intervention of sexual risk behaviors and sexual dysfunctions, highlighting their significance in sexual education and clinical practice.

Substance abuse and male sexual dysfunction: what lies beneath?

INTRODUCTION

Substance abuse has become a worldwide health problem, leading to numerous consequences such as social problems among family members, abnormal behavior, adverse health effects, and psychological problems as well as economic consequences.

OBJECTIVES

We sought to assess the relationship between substance abuse and male sexual health.

METHODS

A search was carried out in the following databases: PubMed, MeSH (Medical Subject Headings), Science Direct, Scopus, Cochrane Library, EMBASE, CINAHL, Academic Search Complete, and the Egyptian Knowledge Bank. The following keywords were used to assess the outcomes for relevant associations: illicit drugs, addiction, substance abuse, sexual health, erectile dysfunction, ejaculatory disorders, impotence, orgasm disorders, and sexual performance.

RESULTS

The initial literature search identified a total of 148 articles in all searched databases. After removal of duplicate studies and application of inclusion/exclusion criteria, 75 reported studies were retained for review, including 38 case-control studies and 37 cross-sectional studies. These articles were classified into the following categories according to the type of abused substance addressed: cannabis/marihuana, 16 articles; opioids, 13 articles; heroin, 11 articles; cocaine, 5 articles; tramadol, 6 articles; ketamine, 2 articles; ecstasy, 4 articles; amphetamine, 2 articles; khat, 7 articles; androgen anabolic steroids, 2 articles; and polydrugs, 7 articles. Most of these recruited articles demonstrated a negative impact of the addressed substance on male sexual health, with variable levels.

CONCLUSION

Substance abuse has negative impacts on male sexual health that should be addressed. More studies conducted with proper methodological and statistical approaches, including logistic regression analysis, are needed to predict the effects of specific substances, considering the rapidly growing effects of non-substance-use disorders on male sexual health.

Abnormal fractional Amplitude of Low-Frequency Fluctuation in chronic ketamine users

BACKGROUND

Ketamine has become a major substance of abuse worldwide. Nevertheless, The long-term effects of ketamine use on intrinsic spontaneous neural activity remain unknown.

OBJECTIVES

In the present study, rs-fMRI was used to explore whether chronic ketamine use changes the intrinsic spontaneous neural activity, and whether the intrinsic spontaneous neural activity changes in chronic ketamine users(CKUs) are associated with cognitive impairments observed in chronic ketamine users.

METHODS

28 CKUs and 30 healthy controls(HC) were enrolled. The fractional amplitude of low-frequency fluctuations (fALFF) was measured to evaluate the intrinsic spontaneous neural activity in multiple brain regions. Cognitive alterations were assessed using MATRICS Consensus Cognitive Battery (MCCB).

RESULTS

CKUs showed higher fALFF in the right parahippocampal gyrus(PHG), right anterior cingulate cortex(ACC), left cerebellar vermis, left posterior cingulate cortex(PCC), bilateral caudate, and lower fALFF in the right middle occipital gyrus(MOG), left cuneus, right precuneus. The fALFF in the right PHG, left cerebellar vermis, bilateral caudate, right ACC of CKUs presented a negative correlation with the average quantity of ketamine use/day(g) and estimated total ketamine consumption. The fALFF in left PCC had a negative correlation with the average quantity of ketamine use/day(g). Speed of processing on MCCB presented a negative correlation with the fALFF in the right MOG.

CONCLUSION

Our study found abnormal fALFF in multiple brain areas in CKUs, which indicated the changes of intrinsic spontaneous neural activity in multiple brain areas. The changes of fALFF were associated with the severity of ketamine use and cognitive impairment in CKUs.

A Scoping Review of the Prevalence and Correlates of Sexual Dysfunction in Adults With Substance use Disorders

BACKGROUND

Substance use may affect sexual functioning in both men and women. Comorbid sexual dysfunction adds to the clinical burden of substance use disorders (SUD).

AIMS

The broad aims were to identify research conduct, types of the available evidence, and research gaps in (i) estimating the incidence, prevalence, type, and severity of sexual dysfunction in adults with SUD; (ii) exploring correlates of sexual dysfunction in SUD.

METHODS

We conducted systematic searches on PubMed, Google Scholar, and Embase for studies published in the English language between August 1954 and November 2020. We included prospective and cross-sectional observational studies that had examined the prevalence or incidence of any sexual dysfunction in adults of either gender with substance use disorders. Review articles and those with an exclusive focus on tobacco use disorders were excluded. The review was registered in PROSPERO.

RESULTS

Our search identified 65 relevant articles, including five prospective studies. All the prospective studies and most of the cross-sectional studies (n = 40) were done among men and subjects with alcohol (n = 20) and opioid (n = 23) use disorders in clinical populations. Substance use and sexual dysfunction were assessed by a wide range of instruments. Prospective studies reported a prevalence of sexual dysfunction at 75% and 61% for alcohol and opioid use disorders, respectively. The prevalence of any sexual dysfunction in cross-sectional studies ranged between 15 and 100 percent. Erectile dysfunction was the most commonly studied and observed sexual dysfunction. Comorbidity and socioeconomic deprivation were consistently associated with a higher occurrence of sexual dysfunctions.

STRENGTHS

We did not limit our review by the type of substances and year of publication. We adhered to the standards of conducting and reporting scoping reviews; hence, our review results should be replicable, transparent, and reliable.

LIMITATIONS

The wide clinical and methodological heterogeneity precluded a systematic review.

CONCLUSION

Research gaps exist in women, non-clinical population, stimulants, and cannabis use disorders, and effect of treatment of SUD in sexual functioning. The quality of evidence is poor.

Behavior-Related Erectile Dysfunction: A Systematic Review and Meta-Analysis

BACKGROUND

Erectile dysfunction (ED) is a common problem among men across the world. It is usually multifactorial in origin. Behavioral factors can be related to the development of ED and related to many other chronic diseases. It impacts not only the sexual function but also the psychology and their overall quality of life.

AIM

To determine the association of the behavior factors in relation to ED and to identify the risk and protective factors.

METHOD

A systematic review search based on Preferred Reporting Items for Systematic Reviews and Meta-Analysis was conducted. The primary databases PubMed, PlosOne, Oxford Academic, SCOPUS, and Ovid were accessed using specific keyword searches. Quality of articles was assessed by using Newcastle-Ottawa Assessment Scale according to the study design.

OUTCOME

Evaluation of the relationship between behavioral factors and ED.

RESULTS

24 studies were identified from the 5 databases which met the predetermined criteria. Overall, the study population include adult male age between 18 and 80 years. The sample size of the studies ranges from 101 to the largest sample size of 51,329. Smoking, alcohol, and drugs usage are found to be risk factors for ED. Meanwhile, dietary intake, physical activity, and intimacy are the protective factors for ED.

CLINICAL IMPLICATION

The findings from this review may aid clinicians to aim for early detection of ED by screening their risk factors and providing early treatment. This can also be used to promote awareness to the community on the sexual health and factors that can affect their sexual function.

STRENGTH & LIMITATION

This study looks at all types of behavioral factors that may affect ED; however, there was a substantial heterogeneity detected across the selected study factors. Furthermore, the lack of PROSPERO registration is also a limitation in this study.

CONCLUSION

Overall, smoking, dietary intake, alcohol consumption, drugs, and physical activities are modifiable risk factors for ED in men. Therefore, it is crucial to promote healthy lifestyle and empower men to prevent ED and early detection of ED for early treatment. Sivaratnam L, Selimin DS, Abd Ghani SR, et al.

Sexual and bladder dysfunction in male ketamine abusers: A large-scale questionnaire study

Purpose

To evaluate the prevalence of lower urinary tract symptoms (LUTS) and erectile dysfunction (ED) in the illicit male ketamine abusers (KA).

Materials and methods

The male street KAs caught by policemen and patients visiting urologic clinics were invited to answer a structured questionnaire including demographic data, illicit drug use related details (duration, frequency, dosage and abstinence status), international prostate symptoms score (IPSS), interstitial cystitis symptoms and problem index (ICSI and ICPI) and International index of erectile function (IIEF-5). Erectile dysfunction was defined as IIEF-5 ≦21.

Results

Finally, we included 1056 participants (993 street, 63 hospital KAs) with a mean age of 27.4 ±6.2 years. ED presented in 30.8% of all KAs. and Hospital KAs were more subject to having ED than street KAs (69.6% vs. 28.0%, p<0.01). Multi-variate analysis revealed that risk factor for male ED were age ≧30 years (OR = 1.765). Subgroup analysis on male street KAs disclosed that abstinence ≧3 months is a protective factor for ED. Lower urinary tract symptoms (ICSI+ICPI ≧12) was prevalent in KAs and multivariate analysis disclosed that significant risk factors for LUTS (ICSI+ICPI ≧12) were age ≧30 years, duration ≧24 months and co-use of other illicit drugs.

Conclusions

Male ED and LUTS were frequently observed in the ketamine abusers. We suggested that street ketamine abuse should be considered in young men presented with ED and LUTS in the clinics.
