Abstract
RATIONALE Sexuality is a central aspect of being human that encompasses many facets. Cannabis, a widely used psychoactive substance, has been associated with various effects on sexuality. The relationship between cannabis and sexuality is complex and multifaceted, involving physiological, psychological, and social factors. OBJECTIVES This review aims to provide an overview of the current literature on the effects of cannabis on several sexual functions, including sexual desire, arousal, orgasm, and sexual satisfaction. It also discusses the potential mechanisms underlying these effects, as well as the impact of dose and frequency of use. RESULTS This review has revealed a complex relationship between cannabis dosage and its influence on sexuality. It appears that the frequency of cannabis use in humans has been associated with the frequency of sexual activities. Individuals who use cannabis more frequently tend to report higher levels of sexual activity. Moreover, there is a notable gender difference in how cannabis affects sexuality. In addition, we found lower doses of cannabis to be linked to heightened sexual desire and enjoyment, whereas higher doses may lead to a decrease in sexual desire and performance. CONCLUSIONS Overall, the association between cannabis and sexuality is complex and warrants further research to better understand the psychological and neurological mechanisms that underlie the effect of cannabis on these sexuality functions and its implications for sexual health. To advance in this endeavor, a crucial step is establishing a precise measurement of dosage in human studies.

[PMID: 38834872 DOI: 10.1038/s41443-024-00925-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/01/2024] [Revised: 05/22/2024] [Accepted: 05/31/2024] [Indexed: 06/06/2024]
Abstract
Previous study has highlighted an association between cannabis use (CU) and an increased risk of erectile dysfunction (ED), potentially due to indirect effects on sex hormonal balance. However, the evidence remains controversial, and the causal relationship is unclear. This study utilized genome-wide association study (GWAS) data to investigate the causal relationships between cannabis use disorder (CUD), lifetime cannabis use (LCU), and ED, as well as levels of sex hormones including estradiol (E2), bioavailable testosterone (BT), follicle-stimulating hormone (FSH), and luteinizing hormone (LH) through Mendelian randomization (MR) analysis. The primary method of analysis was the inverse variance weighted (IVW) method. Data from the FinnGen and UK Biobank were used for replication and meta-analysis. The results indicated no causal relationship between genetically predicted CUD (OR = 0.97, 95% CI 0.87-1.10, P = 0.66) and LCU (OR = 1.13, 95% CI 0.84-1.50, P = 0.42) with the risk of ED. The meta-analysis provided consistent evidence (P > 0.05). No causal relationships were found between CUD and LCU with E2(CUD: β = 0.00, 95% CI 0.00-0.01, P = 0.37; LCU: β = 0.00, 95% CI -0.02-0.01, P = 0.62), BT (CUD: β = 0.00, 95% CI -0.03-0.02, P = 0.90; LCU: β = 0.02, 95% CI -0.04-0.09, P = 0.46), FSH (CUD: β = 0.01, 95% CI -0.18-0.20, P = 0.92; LCU: β = 0.01, 95% CI -0.44-0.47, P = 0.95), and LH (CUD: β = 0.01, 95% CI -0.18-0.21, P = 0.90; LCU: β = 0.13, 95% CI -0.22-0.49, P = 0.46). Sensitivity analyses detected no evidence of horizontal pleiotropy or heterogeneity, ensuring the robustness of the results. In conclusion, this MR analysis did not provide evidence supporting a causal relationship between CU and ED or sex hormone levels.

Abstract
The prevalence of substance use globally is rising and is highest among men of reproductive age. In Africa, and South and Central America, cannabis use disorder is most prevalent and in Eastern and South-Eastern Europe, Central America, Canada and the USA, opioid use disorder predominates. Substance use might be contributing to the ongoing global decline in male fertility, and emerging evidence has linked paternal substance use with short-term and long-term adverse effects on offspring development and outcomes. This trend is concerning given that substance use is increasing, including during the COVID-19 pandemic. Preclinical studies have shown that male preconception substance use can influence offspring brain development and neurobehaviour through epigenetic mechanisms. Additionally, human studies investigating paternal health behaviours during the prenatal period suggest that paternal tobacco, opioid, cannabis and alcohol use is associated with reduced offspring mental health, in particular hyperactivity and attention-deficit hyperactivity disorder. The potential effects of paternal substance use are areas in which to focus public health efforts and health-care provider counselling of couples or individuals interested in conceiving.

Abstract
OBJECTIVE There are contradicting reports regarding the relationship between cannabis use and male sexual functions with almost no data about synthetic cannabinoids (SC) and its effect on male sexual functions. This study investigates psychological concerns related to male sexual functions among cannabis and SC users. The research aims to assess different sexual functions and aspects of sexual psychopathology in cannabis and SCs dependent men compared to controls. METHOD Thirty male patients with cannabis dependence, thirty male patients with SCs dependence and thirty matched controls from the outpatient clinic of Kasr Al Ainy hospital, Egypt, were assessed using Structured Clinical Interview for DSM-IV TR Axis I Disorders (SCID-I), International Index of Erectile Function (IIEF), and Sexuality scale. RESULTS The means of IIEF questionnaire in the cannabis and SC group were significant lower than the means of the control group (P < .001) except the orgasmic function in cannabis group (P = .052). In the SCs group, sexual depression was higher and preoccupation lower than the cannabis (P < .020; P < .003, respectively) and control groups (P < .001; P < .001, respectively). The duration and dose of intake of cannabis and SCs correlated significant with sexual esteem, sexual preoccupation and all domains of IIEF. CONCLUSION Cannabis and SC dependence were associated with lower erectile function, sexual desire, intercourse satisfaction and overall satisfaction, and lower orgasmic functions in the SC group than controls. Both groups showed higher sexual depression, lower sexual esteem and sexual preoccupation than controls. SC has a higher negative impact on male sexual functions and psychopathology than cannabis.

Abstract
BACKGROUND Although it has been assumed that chronic cannabis use may have an unfavorable impact on male sexual function and its metabolic correlates, evidence from clinical studies remains inconclusive. OBJECTIVE To investigate the relationship between cannabis use and sexual behavior, anthropometrics and metabolic/vascular profiles in a large series of men evaluated for sexual dysfunction. METHODS A total of 4800 men (mean age 50.8 years) attending an andrology outpatient clinic for sexual dysfunction were studied. Sexual symptoms, hormonal, metabolic, and instrumental (penile color Doppler ultrasound, PCDU) parameters were evaluated according to the reported habitual use of recreational substances (no use, 1-2 joints/week, >2 joints/week, and use of illicit drugs other than cannabis). RESULTS When compared with non-users, cannabis users were younger and exhibited a lower prevalence of comorbidities as well as better PCDU parameters, despite reporting higher alcohol and tobacco consumption. After adjustment for confounders, cannabis use was associated with a greater instability in the couple's relationship and a higher frequency of masturbation. In addition, the group smoking >2 joints/week showed a significantly lower body mass index than both controls and users of substances other than cannabis. Men who reported using recreational drugs (either cannabis or other) exhibited significantly lower levels of both total and low-density lipoprotein cholesterol than non-users. At the PCDU, smoking 1-2 joints/week was associated with significantly higher dynamic peak systolic velocity than both non-drug use and use of >2 joints/week. Prolactin levels were significantly higher in individuals smoking 1-2 joints/week and in those who used substances other than cannabis when compared with controls, whereas no difference in total testosterone levels was observed. DISCUSSION In men with sexual dysfunction, mild cannabis consumption may be associated with a more favorable anthropometric and lipid profile and with a better penile arterial vascular response to intracavernous prostaglandin injection.

Abstract
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.

Abstract
The endocannabinoid system (ECS) plays a key neuromodulatory role in the brain. Main features of endocannabinoids (eCBs) are that they are produced on demand, in response to enhanced neuronal activity, act as retrograde messengers, and participate in the induction of brain plasticity processes. Sexual activity is a motivated behavior and therefore, the mesolimbic dopaminergic system (MSL) plays a central role in the control of its appetitive component (drive to engage in copulation). In turn, copulation activates mesolimbic dopamine neurons and repeated copulation produces the continuous activation of the MSL system. Sustained sexual activity leads to the achievement of sexual satiety, which main outcome is the transient transformation of sexually active male rats into sexually inhibited animals. Thus, 24 h after copulation to satiety, the sexually satiated males exhibit a decreased sexual motivation and do not respond to the presence of a sexually receptive female with sexual activity. Interestingly, blockade of cannabinoid receptor 1 (CB1R) during the copulation to satiety process, interferes with both the appearance of the long-lasting sexual inhibition and the decrease in sexual motivation in the sexually satiated males. This effect is reproduced when blocking CB1R at the ventral tegmental area evidencing the involvement of MSL eCBs in the induction of this sexual inhibitory state. Here we review the available evidence regarding the effects of cannabinoids, including exogenously administered eCBs, on male rodent sexual behavior of both sexually competent animals and rat sub populations spontaneously showing copulatory deficits, considered useful to model some human male sexual dysfunctions. We also include the effects of cannabis preparations on human male sexual activity. Finally, we review the role played by the ECS in the control of male sexual behavior expression with the aid of the sexual satiety phenomenon. Sexual satiety appears as a suitable model for the study of the relationship between eCB signaling, MSL synaptic plasticity and the modulation of male sexual motivation under physiological conditions that might be useful for the understanding of MSL functioning, eCB-mediated plasticity and their relationship with motivational processes.

Abstract
INTRODUCTION Cannabis use is increasing across the United States, yet its short- and long-term effects on sexual function remain controversial. Currently, there is a paucity of studies exploring the relationship between cannabis and men's health. OBJECTIVES To summarize the available literature on cannabis and men's health and provide insight into lay perceptions of this topic. METHODS We performed a qualitative PubMed review of the existing literature on cannabis and men's health according to the PRISMA guidelines. Separately, we analyzed relevant themes in online men's health forums. We utilized a Google cloud-based platform (BigQuery) to extract relevant posts from 5 men's health Reddit forums from August 2018 to August 2019. We conducted a qualitative thematic analysis of the posts and quantitatively analyzed them using natural language processing and a meaning extraction method with principal component analysis. RESULTS Our literature review revealed a mix of animal and human studies demonstrating the negative effects of cannabis on semen parameters and varying effects on erectile function and hormone levels. In our analysis of 372 686 Reddit posts, 1190 (0.3%) included relevant discussion on cannabis and men's health. An overall 272 posts were manually analyzed, showing that online discussions revolve around seeking answers and sharing the effects of cannabis on various aspects of sexual health and quality of life, often with conflicting experiences. Quantitative analysis revealed 1 thematic cluster related to cannabis, insecurity, and mental/physical health. CONCLUSIONS There is a limited number of quality human studies investigating the effects of cannabis on men's health. Men online are uncertain about how cannabis affects their sexual health and seek more information. As the prevalence of cannabis use increases, so does the need for research in this area.

Abstract
Cannabis is the most commonly used federally illegal drug in the United States and world, especially among people of reproductive age. In addition, the potency of cannabis products has increased significantly in the past decade. This is concerning because the available evidence suggests an adverse effect from cannabis exposure on male and female reproductive health. Exposure to cannabinoids may have differential impacts on female reproductive health across a woman's lifespan, from preconception to pregnancy, throughout lactation, and during menopause. Even more, cannabis use has been associated an adverse effect on fetal outcomes, and longer-term offspring health and developmental trajectories. Despite the prevalence of cannabis use, there is limited available evidence regarding its safety, especially in regard to reproductive health, pregnancy and lactation. The biological effects of cannabis are mediated by the endocannabinoid system and studies have reported the presence of cannabinoid receptors in the male and female reproductive tract, on sperm and the placenta, suggesting the endocannabinoid system plays a role in regulating reproduction. Cannabis use can impact male and female fertility and has been associated with altered reproductive hormones, menstrual cyclicity and semen parameters. Use of cannabis in males has also been associated with erectile dysfunction, abnormal spermatogenesis, and testicular atrophy. In females, cannabis use has been associated with infertility and abnormal embryo implantation and development. The main psychoactive component of cannabis, delta-9-tetrahydrocannabinol (THC), can also cross the placenta and has been detected in breastmilk. Maternal cannabis use during pregnancy and lactation has been associated with adverse effects including small for gestational age infants, preterm birth, fetal neurodevelopmental consequences, and impaired offspring sociobehavioral and cognitive development. The prevalence of cannabis use to alleviate menopausal symptoms has also increased despite the limited information on its benefits and safety. As cannabis use is on the rise, it is critical to understand its impact on reproductive health and offspring developmental outcomes. This is an understudied, but timely subject, with much needed information to guide healthcare providers and those interested in conceiving, or that are pregnant and lactating, as well as those at the end of their reproductive time span.

Abstract
Objectives. Assessing the effectiveness and tolerability of medical cannabis (MC) treatment on Gilles de la Tourette syndrome (GTS) patients. Methods. We report on an open-label, prospective study on the effect of MC on adult GTS patients. MC mode of use was decided by the treating neurologist and the patient. Δ9-Tetrahydrocannabinol (Δ9-THC) and cannabidiol (CBD) content within MC product and monthly dose were titrated during the study. Following treatment initiation, patients were assessed after 4 and 12 weeks for efficacy, tolerability, and side effects. Results. Eighteen patients entered the study. Baseline Yale Global Tic Severity Scale- (YGTSS) Total (range 0-100) was
. Three patients did not reach the end of follow-up period. The most common mode of administration was smoking (80%). Following twelve weeks of treatment, a significant 38% average reduction (
) of YGTSS-Total and a 20% reduction (
) of Premonitory Urge for Tic Scale (PUTS) were observed. Common side effects were dry mouth (66.7%), fatigue (53.3%), and dizziness (46.7%). Three patients suffered from psychiatric side effects including worsening of obsessive compulsive disorder (stopped treatment), panic attack, and anxiety (resolved with treatment modification). Six patients (40%) reported cognitive side effects regarding time perception, visuospatial disorientation, confusion, slow processing speed, and attention. Conclusions. MC treatment demonstrates good efficacy and tolerability in adult GTS patients. Predilection for smoking rather than using oil drops requires further comparative studies to evaluate the efficacy of each. Cognitive and psychiatric side effects have to be monitored and addressed.

[PMID: 35052235 PMCID: PMC8775629 DOI: 10.3390/healthcare10010071] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/30/2021] [Revised: 12/24/2021] [Accepted: 12/28/2021] [Indexed: 12/03/2022] Open
Abstract
The consumption of cannabis and alcohol results in a variety of effects on the psychic functions of young users. Notwithstanding their widespread and prevalent use, the impact of these drugs on sexual health remains unknown. Thus, the aim of this study is to analyse the influence of alcohol and cannabis consumption on sexual function in young people. An observational study was conducted in 274 participants aged 18–30 years. The following selection tools were used: Alcohol Use Disorders Identification Test, Cannabis Abuse Screening Test (CAST), and Changes in Sexual Functioning Questionnaire Short-Form. Participants who were at high risk of having cannabis-related problems performed better on the CAST concerning sexual function, arousal, and orgasm. Participants at high risk had higher arousal and orgasm scores than those who were not at risk for cannabis problems. Improvements in sexual function were found between people who were at high risk of having alcohol problems and those who were not at risk. Sexual function in young people who use cannabis and alcohol more frequently was shown to be better than in those who do not use either, highlighting the need for more information aimed at the young population.

Abstract
PURPOSE OF REVIEW Recent widespread legalization changes have promoted the availability of marijuana and its increased potency and perceived safety. The limited evidence on reproductive and perinatal outcomes from marijuana exposure is enough to warrant concern and action. The objective of this review is to provide a current and relevant summary of the recent literature surrounding this topic. RECENT FINDINGS The available published studies on the effect of marijuana exposure on reproductive health and pregnancy outcomes are conflicting. Human studies are often observational or retrospective and confounded by self-report and polysubstance use. However, the current, limited evidence suggests that marijuana use adversely affects male and female reproductive health. Additionally, prenatal marijuana exposure has been reported to be associated with an increased risk of preterm birth and small for gestational age infants. SUMMARY With the increasing prevalence of marijuana use, there is an urgent need for evidence-driven recommendations and guidelines for couples interested in conception, affected by infertility or who are expecting. At this time, no amount of marijuana use during conception or pregnancy is known to be well tolerated and the limited available evidence suggests that the safest choice is to abstain.

Abstract
INTRODUCTION International studies have suggested that social disruptions caused by the COVID-19 pandemic have led to sexual dysfunction, but the impact on males in the United States is less defined. AIM To examine changes in male sexual function during the COVID-19 pandemic and to evaluate associated demographic variables. METHODS Prepandemic survey data was collected between October 20, 2019 and March 1, 2020 on adult males in the United States. Follow-up survey data collected for comparison during the COVID-19 pandemic between August 1, 2020 and October 10, 2020 included International Index of Erectile Function (IIEF) scores, Patient Health Questionnaire for Depression and Anxiety with 4 items (PHQ-4) scores, and questions regarding sexual frequency. Questions were also asked about mask-wearing habits, job loss, relationship changes, and proximity to individuals who tested positive for COVID-19. MAIN OUTCOME MEASURES Differences in prepandemic and pandemic male sexual function assessed by self-reported IIEF domain scores and sexual frequency RESULTS: Seventy six men completed both prepandemic and pandemic surveys with a mean age of 48.3 years. Overall, there were no differences in either overall IIEF score or any subdomain score when comparing men's pre-pandemic and pandemic survey data. There was an increase in sexual frequency during the pandemic with 45% of men reporting sex ten or more times per month during the pandemic compared to only 25% of men prior to the pandemic (P = .03). Among the subgroup of 36 men who reported a decrease in IIEF, the decrease was an average of 3.97, and significantly associated with higher PHQ-4 depression subscale scores (1.78 vs 1.03, P = .02). CONCLUSION The COVID-19 pandemic is associated with increased sexual frequency and no change in overall sexual function in males in the United States. Interventions intended to promote male sexual health during the COVID-19 pandemic should include a focus on mental health. Chen T, Bhambhvani HP, Kasman AM, et al.

Abstract
Introduction International studies have demonstrated increasing rates of sexual dysfunction amidst the coronavirus disease 2019 (COVID-19) pandemic; however, the impact of the pandemic on female sexual function in the United States is unknown. Aim To assess the impact of the COVID-19 pandemic on female sexual function and frequency in the United States. Methods A pre-pandemic survey containing the Female Sexual Function Index (FSFI) and demographic questions was completed by adult women in the United States from October 20, 2019 and March 1, 2020. The same women were sent a follow-up survey also containing the FSFI, as well as the Patient Health Questionnaire for Depression and Anxiety with 4 items (PHQ-4), and questions pertaining to mask wearing habits, job loss, and relationship changes. Risk for female sexual dysfunction (RFSD) was defined as FSFI < 26.55. Main Outcome Measure Differences in pre-pandemic and intra-pandemic female sexual function, measured by the FSFI, and sexual frequency. Results Ninety-one women were included in this study. Overall FSFI significantly decreased during the pandemic (27.2 vs 28.8, P = .002), with domain-specific decreases in arousal (4.41 vs 4.86, P = .0002), lubrication (4.90 vs 5.22, P = .004), and satisfaction (4.40 vs 4.70, P = .04). There was no change in sexual frequency. Contingency table analysis of RFSD prior to and during the pandemic revealed significantly increased RFSD during the pandemic (P = .002). Women who developed RFSD during the pandemic had higher PHQ-4 anxiety subscale scores (3.74 vs 2.53, P = .01) and depression subscale scores (2.74 vs 1.43, P = .001) than those who did not. Development of FSD was not associated with age, home region, relationship status, mask wearing habits, knowing someone who tested positive for COVID-19, relationship change, or job loss and/or reduction during the pandemic. Conclusion In this population of female cannabis users, risk for sexual dysfunction increased amidst the COVID-19 pandemic and is associated with depression and anxiety symptoms.
