Abstract Introduction: Cannabis is commonly used for its medicinal and therapeutic benefits and is also widely used as a recreational drug. Cannabis use has been increasing in Canada, including among Canadian women of reproductive age. Post-legalization, further increases in cannabis use are expected due to increased availability and lowered perceptions of harm. Although cannabinoids are well known for their effects on the central and peripheral nervous systems, endocannabinoid receptors have also been characterized throughout the female reproductive tract. Cannabinoids may affect many aspects of female reproductive health, including fertility, pregnancy outcomes with neonatal implications, and menopause. Purpose: To provide a comprehensive review of trends...

Abstract With legalisation of cannabis for both medicinal and recreational use expanding to more world nations, grasping its effects on the human body is vital. The microbiome is critical to human health and disease, and accumulating data suggests that it is influenced by a variety of external variables, including marijuana/cannabis and cannabinoids. We therefore conducted a comprehensive assessment of the literature to analyse cannabis and cannabinoid effects on the human microbiota. We searched PubMed, Embase and Cochrane Library CENTRAL databases for studies involving the use of marijuana, medical cannabis, cannabinoids and cannabinoid-like lipid mediators on microbiota, across all clinical conditions. Nine studies were identified:...

Abstract Background The growing international movement legislating medical marijuana has brought renewed interest to the role of marijuana smoking on fertility potential. Although studies have identified that sperm quality can be compromised by marijuana use, little focus has been placed specifically on those trying to conceive. In this study, we aimed to clarify the impact of marijuana use in semen quality in men being investigated for assisted reproduction. Materials and methods We conducted a cross-sectional study at a university-based facility in Jamaica. Routine semen analyses were performed on 229 men ages 23–72 years who were new clients. Logistic regression analyses were performed in order to...

Abstract Objective: Type-2 diabetes (T2D) is a multifactorial disease that occurs as a result of impaired insulin secretion and increased glucose. Researchers emphasize that oxidative stress prevention and improvement strategies are important in the general treatment of T2D. It is reported that delta-9-tetrahydrocannabinol (THC), a component of the cannabis plant, has positive effects against oxidative stress and inflammation. Therefore, this study explored the inhibitory effects of THC on oxidative damage of testis in type-2 diabetic rats. Materials and Methods: Adult Spraque-Dawley rats were separated into 4 groups. In the control group, physiological saline was given intraperitoneally. In the T2D model group (T2DM), streptozotocin (STZ)...

Introduction Scientific research on the effects of marijuana on sexual functioning in women, including libido, arousal, orgasm, and satisfaction, is limited. Aim To evaluate women’s perceptions of the effect of marijuana use before sexual activity. Methods A cross-sectional design, from March 2016–February 2017, within a single, academic, obstetrics and gynecology practice, was performed. Patients were given a questionnaire at their visit and asked to complete it anonymously and place it in a locked box after their visit. Main Outcome Measures The primary outcome was satisfaction in the sexual domains of drive, orgasm, lubrication, dyspareunia, and overall sexual experience. The secondary outcome was the effect...

Endocannabinoids act as a major neuromodulatory system in a variety of physiological and behavioral functions. Three major lines of evidence suggest that the endocannabinoid system interacts with gonadal hormones. First, the endocannabinoid system is implicated in behaviors and physiological functions that are known to be regulated in part by gonadal hormones. Second, receptors and metabolic enzymes of the endocannabinoid system are localized extensively on structures in the hypothalamic-pituitary-gonadal axis. Third, changes in levels of gonadal hormones alter endocannabinoid signaling. Here we reviewed and summarized the current evidence regarding the interaction between the endocannabinoid system and androgens, estrogens, and progesterone. Overall, it appears that bidirectional...
