humulene and Infertility--Male

To review the evidence regarding a decrease in worldwide sperm parameters and discuss potential causative factors.. The topic of worldwide decline in sperm parameters is contentious; however, recent high-quality studies have demonstrated that there is indeed a decline in sperm parameters. Several retrospective and basic science studies have shown possible links for this decline in sperm parameters such as obesity, diet, and environmental toxins.. There exist substantial data to suggest a decline in sperm counts over time. Although causative factors have yet to be fully elucidated, potential causes include, increased rates of obesity, poor diet, and exposure to environmental toxins. How this decline in sperm counts reflects fertility has yet to be determined. As such, further studies are necessary to evaluate whether this decline in sperm count correlates with decreased fecundity and how to identify and mitigate potential causative factors.

In the United States of America (USA), cannabis is legal in 28 states for medical purposes and 8 states for recreational use. In 2016, the legal marijuana industry reached nearly $7 billion in sales in the USA alone. Although consumption continues to increase, the medical effects of marijuana remain understudied. Young males comprise the demographic most likely to consume cannabis, and these individuals will be most vulnerable to its short- and long-term consequences.. The purpose of this manuscript is to systematically review the available literature describing the effects of marijuana on male infertility, sexual health, and urologic neoplasms.. A comprehensive literature search was conducted using the Medline and Embase databases through May 2017. In vitro models, animal models, case series, case-control, and cohort designs were included. The Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) statement was utilized to report results.. After exclusions, 91 articles were synthesized for qualitative analysis. Of these manuscripts, 30 pertained to marijuana and male infertility, 36 discussed cannabis and male sexual health/hormones, and 25 explored the relationship between marijuana and urologic neoplasms.. With respect to male factor fertility using semen parameters as a surrogate, cannabinoids likely play an inhibitory role. Data on marijuana and male sexual function are mixed but suggest that marijuana may enhance the subjective experience of sexual intercourse while potentially contributing to ED in a dose-dependent manner. Cannabis has been associated with both increased and decreased risk of malignancy depending upon the target organ. Marijuana exposure seems to be an independent risk factor for testis cancer, data on bladder cancer are conflicting, and the evidence on prostate cancer supports anti-neoplastic effects of cannabinoids.. Studies of the effects of cannabis suggest impact on urologic health and disease. Prospective, long-term studies are necessary for further elucidation of these effects.

In this last century, an increase of men infertility has been registered. It has been suggested that environmental factors could a negative impact over sperm quality. Among these factors, impact of environmental toxicant has been spread by media. In this review of scientific literature, we identify several environmental factors that could impact men fertility in a negative way. These factors are tobacco, marijuana, weight, body mass index, heat, nutritional state, electromagnetic waves and altitude. For each of these factors, the impact over men fertility, their mechanism, as well their influence over the use of Assisted Reproductive Technics are reported.

Marijuana has the highest consumption rate among all of the illicit drugs used in the USA, and its popularity as both a recreational and medicinal drug is increasing especially among men of reproductive age. Male factor infertility is on the increase, and the exposure to the cannabinoid compounds released by marijuana could be a contributing cause. The endocannabinoid system (ECS) is deeply involved in the complex regulation of male reproduction through the endogenous release of endocannabinoids and binding to cannabinoid receptors. Disturbing the delicate balance of the ECS due to marijuana use can negatively impact reproductive potential. Various in vivo and in vitro studies have reported on the empirical role that marijuana plays in disrupting the hypothalamus-pituitary-gonadal axis, spermatogenesis, and sperm function such as motility, capacitation, and the acrosome reaction. In this review, we highlight the latest evidence regarding the effect of marijuana use on male fertility and also provide a detailed insight into the ECS and its significance in the male reproductive system.

Male factor contributes to up to 50% of cases of couples experiencing infertility. Cannabis is one of the most commonly used recreational drugs, and its effects on the reproductive system have been largely debated in the literature.. The aim of this study is to evaluate the effect of recreational cannabis use on total T (tT) levels, gonadal status, and sperm parameters in a cohort of primary infertile non-Finnish, white-European men.. Data of 2074 white-European men visited for primary couple's infertility were analyzed. Lifestyle factors and cannabis use were investigated in all participants. Semen analyses were based on the 2010 World Health Organization reference criteria. Serum hormones were evaluated, and patients were subdivided based on their gonadal status. Health-significant comorbidities were scored with the Charlson Comorbidity Index (CCI). Descriptive statistics and linear regression analyses were used to test the association between cannabis use, sperm parameters, and hormonal levels. Logistic regression analyses tested potential predictors for abnormal sperm parameters and gonadal status.. Of 2074, 225 (10.9%) patients reported cannabis use in their lifetime. Total Testosterone levels were lower in cannabis users compared to nonusers (p = 0.03). In a multivariable linear regression analysis, cannabis use was inversely associated with tT levels (ß = -0.372 ng/ml; p = 0.005) but not with follicle-stimulating hormone nor with luteinizing hormone levels. Conversely, at multivariable logistic regression model cannabis use was not associated with the type of hypogonadism. At multivariable linear regression analysis, cannabis use was inversely associated with sperm morphology (p = 0.007), while not with both sperm concentration and sperm motility. Similarly, at adjusted logistic regression analysis cannabis use resulted associated with teratozoospermia (p = 0.039) but not with oligo-, astheno-, and azoospermia.. Infertile men using cannabis are at higher risk of having lower testosterone levels and altered sperm morphology as compared with nonusers.

Although therapeutic effect of quercetin (Quer) was reported on non-alcoholic fatty liver disease (NAFLD), destructive effects have been shown on male fertility due to its pro-oxidative properties. On the other hand, NAFLD impairs germ cells to produce sperm and leads to male infertility. Herein, a biocompatible and green bigel was designed for Quer delivery to prevent infertility induced by NAFLD as the increasing complications. Bigels were prepared using cottonseed oil/cannabis oil/alginate/ferula gum and optimized by the mixture design method. NAFLD was induced by 58% of dietary calorie as lard and 42 g/l fructose for 16 weeks in Sprague-Dawley rats. So on animals received 2 mg/kg Quer loaded on bigels, free bigels, or free Quer for 45 days as daily gavage. Semen was analyzed, followed by the assessment of DNA integrity. Count, motility, and normal morphology reached the healthy control group at the bigel-Quer-treated one. Moreover, all of these parameters were significantly higher in the bigel-Quer group than the Quer and bigel, alone. The percent of sperms with head and tail abnormality decreased considerably in the bigel-Quer group compared with the Quer, free bigel, and NAFLD groups. Serum testosterone levels significantly increased and reached the healthy control group in the bigel-Quer group. DNA fragmentation of sperm significantly decreased in the bigel-Quer group (p < 0.05). The bigel showed synergistic effects with Quer for treating infertility in rats with NAFLD.
