[PMID: 38929646 PMCID: PMC11205111 DOI: 10.3390/life14060662] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/16/2024] [Revised: 05/11/2024] [Accepted: 05/21/2024] [Indexed: 06/28/2024] Open
Abstract
The secondary sex ratio (SSR), indicating the ratio of male to female live births, has garnered considerable attention within the realms of reproductive biology and public health. Numerous factors have been posited as potential trendsetters of the SSR. Given the extensive research on the impact of daily behaviors and habits on individuals' reproductive health, there is a plausible suggestion that lifestyle choices may also influence the SSR. By synthesizing the existing literature on the current research field, this comprehensive review indicates that an elevated SSR has been associated with an increased intake of fatty acids and monosaccharides, proper nutrition, higher educational levels, financial prosperity, and favorable housing conditions. On the other hand, a decreased SSR may be linked to undernutrition, socioeconomic disparities, and psychological distress, aligning with the Trivers-Willard hypothesis. Occupational factors, smoking habits, and cultural beliefs could also contribute to trends in the SSR. Our review underscores the significance of considering the aforementioned factors in studies examining the SSR and emphasizes the necessity for further research to unravel the mechanisms underpinning these connections. A more profound comprehension of SSR alterations due to lifestyle holds the potential to adequately develop public health interventions and healthcare strategies to enhance reproductive health and overall well-being.

Wang B, Zhang H, Zhang X, Wang J, Wang H, Jiang J. Association between urinary concentrations of polycyclic aromatic hydrocarbons and risk of endometriosis in the NHANES 2003-2006. ENVIRONMENTAL SCIENCE AND POLLUTION RESEARCH INTERNATIONAL 2023; 30:117715-117728. [PMID: 37872335 DOI: 10.1007/s11356-023-30545-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/17/2023] [Accepted: 10/13/2023] [Indexed: 10/25/2023]
Abstract
To explore the association between exposure to polycyclic aromatic hydrocarbons (PAHs) and endometriosis risk. Data were obtained from the 2003-2006 National Health and Nutrition Examination Survey database. Urinary concentrations of PAHs were divided into quartiles, and weighted multivariate logistic regression, restricted cubic spline, and subgroup analyses were performed. An extreme gradient boosting (XGBoost) algorithm was used to screen the most important PAHs. After multivariable adjustments, 9-fluorene, 1-phenanthrene, 2-phenanthrene, and 4-phenanthrene exposure were significantly associated with a risk of endometriosis. Specifically, compared with the reference group, the odds ratios (ORs) of endometriosis for the fourth quartile were 3.52 (95% confidence interval (CI): 1.15, 10.77), 3.10 (95% CI: 1.37, 6.97), 4.86 (95% CI: 1.93, 12.21), and 2.67 (95% CI: 1.02, 7.01) for 9-fluorene, 1-phenanthrene, 2-phenanthrene, and 4-phenanthrene, respectively. In terms of continuous exposure, each one-standard-deviation increase in the urinary concentration of 9-fluorene, 1-phenanthrene, 2-phenanthrene, and 4-phenanthrene was independently associated with a 66% (OR: 1.66, 95% CI: 1.15, 2.40), 62% (OR:1.62, 95% CI: 1.19, 2.20), 68% (OR: 1.68, 95% CI: 1.24, 2.28), and 56% (OR: 1.56, 95% CI: 1.11, 2.19) increase in the risk of endometriosis, respectively, in the fully adjusted model. A significant association between the urinary concentration of 9-fluorene and the risk of endometriosis was also observed in participants who had a high body-mass index (≥25 kg/m2), with a corresponding OR of 2.61 (95% CI: 1.37, 5.00; P for interaction = 0.006). Our findings show that high urinary concentrations of PAHs were associated with a high risk of endometriosis in participants and that the urinary concentration of 9-fluorene was related with a high susceptibility of endometriosis in participants with overweight.

Abstract
OBJECTIVE Currently, the association between smoking, alcohol, and coffee intake and the risk of ovarian cancer (OC) remains conflicting. In this study, we used a two-sample mendelian randomization (MR) method to evaluate the association of smoking, drinking and coffee consumption with the risk of OC and prognosis. METHODS Five risk factors related to lifestyles (cigarettes per day, smoking initiation, smoking cessation, alcohol consumption and coffee consumption) were chosen from the Genome-Wide Association Study, and 28, 105, 10, 36 and 36 single-nucleotide polymorphisms (SNPs) were obtained as instrumental variables (IVs). Outcome variables were achieved from the Ovarian Cancer Association Consortium. Inverse-variance-weighted method was mainly used to compute odds ratios (OR) and 95% confidence intervals (Cl). RESULTS The two-sample MR analysis supported the causal association of genetically predicted smoking initiation (OR: 1.15 per SD, 95%CI: 1.02-1.29, P = 0.027) and coffee consumption (OR: 1.40 per 50% increase, 95%CI: 1.02-1.93, P = 0.040) with the risk of OC, but not cigarettes per day, smoking cessation, and alcohol consumption. Subgroup analysis based on histological subtypes revealed a positive genetical predictive association between coffee consumption and endometrioid OC (OR: 3.01, 95%CI: 1.50-6.04, P = 0.002). Several smoking initiation-related SNPs (rs7585579, rs7929518, rs2378662, rs10001365, rs11078713, rs7929518, and rs62098013), and coffee consumption-related SNPs (rs4410790, and rs1057868) were all associated with overall survival and cancer-specific survival in OC. CONCLUSION Our findings provide the evidence for a favorable causal association of genetically predicted smoking initiation and coffee consumption with OC risk, and coffee consumption is linked to a greater risk of endometrioid OC.

Awareness, knowledge, and psycho-emotional aspect of infertility among women seeking fertility assistance at a tertiary care hospital in Chhattisgarh, a cross-sectional study. JOURNAL OF EDUCATION AND HEALTH PROMOTION 2023; 12:3. [PMID: 37034877 PMCID: PMC10079196 DOI: 10.4103/jehp.jehp_581_22] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 04/22/2022] [Accepted: 07/21/2022] [Indexed: 06/19/2023]
Abstract
BACKGROUND The lack of fundamental knowledge and awareness about the biological process of reproduction is low worldwide but has reportedly higher incidence rates in under-developed countries. Infertility can have a tremendous effect on a woman's psychological and social well-being, pushing her toward mental stress, anxiety, depression self-blame, self-isolation, feeling of worthlessness, and lack of interest in life. The present study was conducted to determine the level of knowledge and awareness regarding factors affecting fertility and also to ascertain the emotional status of females visiting the Obstetrics and Gynecology out-patient department for fertility assistance. MATERIALS AND METHODS A cross-sectional study was performed by using a questionnaire which had two parts; the first part had questions about awareness and knowledge of the subject of infertility, and the second part had 12 questions that assessed the psychological and emotional status of the participants, and it also explored prevailing myths about infertility based on a validated questionnaire. RESULTS There was a significant difference in mean knowledge score; those who were more educated had better knowledge of various aspects of infertility. The overall adequacy for knowledge and awareness revealed that only 62 (47.7%) of the participants had adequate knowledge (score >6) regarding female infertility. The mean score for knowledge among all the respondents was 6.61 ± 1.48. The overall emotional and psychological score suggested that 30 (23%) of the respondents were disturbed because of stress because of infertility. CONCLUSION Infertility can have a serious impact on the psychological well-being of females, and social pressure and stigma associated with childlessness can further worsen the physical and emotional well-being of couples, which needs to be addressed before starting treatment of infertility for a better response to treatment. The limited knowledge and prevailing mis-conceptions regarding infertility need to be sincerely dealt with to complement the medical treatment of infertility.

[PMID: 36478891 PMCID: PMC9720145 DOI: 10.3389/frph.2022.1037379] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/05/2022] [Accepted: 10/17/2022] [Indexed: 07/30/2023] Open
Abstract
Exposures to heavy metals and metalloids have been associated with decreased fecundity and fertility in couples conceiving via assisted reproduction. Heavy metals and metalloids can alter the homeostasis of critical hormones controlling sexual maturation by binding to critical hormones and receptors. This may disrupt the time course of sexual maturation directly or indirectly affecting reproductive competence in males and females. The present review aims to provide a summarized overview of associations between heavy metal exposure, reproductive concerns, and IVF outcomes. A systematic review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) in Google Scholar, Scopus, EMBASE and PubMed databases. Initial search produced 1,351 articles from which 30 articles were eligible to be included in the systematic review. From our results, 16 articles reported associations between selected heavy metals and IVF outcomes, while 14 articles summarized the role of heavy metals in reproductive concerns. For the studies on IVF outcomes, different human samples were examined for heavy metals. Heavy metals and metalloids (Pb, Hg, Cd, Cr, Mn, As) correlated negatively with oocyte fertilization/pregnancy rates in hair, follicular fluid, serum, urine and seminal plasma samples, while Cd and Hg in whole blood samples showed no associations. For the studies on reproductive concerns, high levels of heavy metals/metalloids were implicated in the following conditions: infertility (Cd, Pb, Ba, U), spontaneous abortion/miscarriage (Pb, Cd, Sb), congenital heart disease (Al, Mg, Cd), PCOS (As, Cd, Hg, Pb), endometriosis (Pb) and uterine leiomyomata (Hg). Taken together, the results of our study suggest that the impact of heavy metals and metalloids exposure on reproductive health may contribute to the failure rates of in vitro fertilization.

Abstract
The consumption of energy drinks is common among adolescents and young adults. The possible effects (mainly behavioral and reproductive) of ingestion in this population remain unknown. For this reason, this study aimed to evaluate the behavioral and reproductive effects of energy drinks and their main constituents (caffeine and taurine), as well as their combinations with alcohol, via a binge drinking protocol in male and female Wistar rats during puberty. In this study, 100 male and 100 female rats were treated with a binge drinking protocol 3 days a week over 4 weeks from postnatal day (PND) 28 to PND 60, which included 10 mL/kg by oral gavage of distilled water, energy drink, caffeine (3.2 mg/kg), taurine (40 mg/kg), and their combinations with alcohol (2 g/kg). The animals were evaluated by behavioral tests from PND 56 to PND 60 (open field, plus maze and object recognition) and reproductive parameters (estrous cycle regularity, weight of sexual organs, oocyte quality, spermatid and sperm count, sperm morphology and testosterone level). Locomotor activity was increased in females in the groups combined with alcohol (except alcohol + caffeine) and in the caffeine group. Long-term memory was increased in males in the caffeine and taurine groups even when combined with alcohol. The combination of energy drinks and alcohol did not have significant effects on the reproductive parameters of either sex of rats during puberty. We concluded that energy drinks (and their main constituents) and alcohol combinations did not cause alterations in reproductive profiles, and locomotor activity and long-term memory were increased in females and males, respectively.

Abstract
In the recent decade, numerous new psychoactive substances (NPSs) have been added to the illicit drug market. These are synthetized to mimic the effects of classic drugs of abuse (i.e., cannabis, cocaine, etc.), with the purpose of bypassing substance legislations and increasing the pharmacotoxicological effects. To date, research into the acute pharmacological effects of new NPSs is ongoing and necessary in order to provide an appropriate contribution to public health. In fact, multiple examples of NPS-related acute intoxication and mortality have been recorded in the literature. Accordingly, several in vitro and in vivo studies have investigated the pharmacotoxicological profiles of these compounds, revealing that they can cause adverse effects involving various organ systems (i.e., cardiovascular, respiratory effects) and highlighting their potential increased consumption risks. In this sense, NPSs should be regarded as a complex issue that requires continuous monitoring. Moreover, knowledge of long-term NPS effects is lacking. Because genetic and environmental variables may impact NPS responses, epigenetics may aid in understanding the processes behind the harmful events induced by long-term NPS usage. Taken together, “pharmacoepigenomics” may provide a new field of combined study on genetic differences and epigenetic changes in drug reactions that might be predictive in forensic implications.

Abstract
With the ever-increasing consumption of pharmaceutical compounds, their presence in the environment is now an undisputable reality. The majority of these compounds are released into the wild after their therapeutic use, as biotransformation products or in their original form. The presence of this class of compounds in the environment, due to their biological properties, can exert effects on non-target organisms, with adverse consequences. In addition, some bioactive substances, such as stimulants of the central nervous system, are also used by humans as part of their diet. The adverse consequences posed by such chemicals may be permanent or transient, if the exposure to xenobiotics is halted; it is thus of the paramount importance to study effects that result from long-term exposure to toxicants, but also the recovery of organisms previously exposed to such substances, especially if such chemicals may cause some type of addiction. Caffeine (1,3,7-trimethylxanthine) is a naturally occurring alkaloid found in many plants, being one of the most common stimulant/pharmaceutical compounds found in the environment. In addition, it is addictive, and strongly consumed by humans, a factor that contributes also for its continuous presence in the aquatic environment. The aim of this study was to evaluate the effects of environmentally relevant concentrations (0.08; 0.4; 2; 10; and 50 μg/L) of caffeine on behavior and physiological parameters (that are proxies of metabolic traits, such as oxygen uptake and glycogen content), in individuals of the freshwater crustacean species Daphnia magna, of distinct ages, and with or without a recovery period in the absence of caffeine. Regarding behavior, the results indicated that caffeine exposure altered the moved distance of the test organisms, but not according to a coherent pattern; low concentrations of caffeine reduced the movement of exposed daphnids, while higher levels did not have any measurable effect on this parameter. In addition, it was possible to identify subtle withdrawal effects (animals exposed to caffeine during 21 days and kept in uncontaminated media for 2 days). Regarding the other two studied parameters, caffeine exposure did not result in any significant modification in oxygen uptake and glycogen stores/reserves of the test organisms, in animals continuously exposed, or in those subjected to a recovery period, suggesting that despite a behavioral stimulatory effect, this was not followed by any metabolic change, and no addictive effect was possible to infer. The results showed that the presence of caffeine in environmental concentrations can induce mild behavioral effects at low, albeit realistic levels, but not capable of establishing clear biochemical changes.

Abstract
Nutrition and lifestyle have a great impact on reproduction and infertility in humans, as they are essential for certain processes such as implantation, placental growth, angiogenesis, and the transfer of nutrients from the mother to the fetus. The aim of this review is to provide the interconnection between nutrition and reproductive health through the insight of omics approaches (including metabolomics and nutrigenomics). The effect of various macronutrients, micronutrients, and some food‐associated components on male and female reproduction was discussed. Recent research work was collected through database search from 2010 to 2020 to identify eligible studies. Alterations of metabolic pathways in pregnant women were deliberated with an emphasis on different strategies of lifestyle and dietary interventions. Several nutritional methods, which are important for embryonic and child neurological development, nutritional supplements to lactation, and improved gestational length along with birth weight have been emphasized. Considerable advances in omics strategies show potential technological development for improving human reproductive health.

The Relation between Caffeine Consumption and Endometriosis: An Updated Systematic Review and Meta-Analysis. Nutrients 2021; 13:nu13103457. [PMID: 34684458 PMCID: PMC8538723 DOI: 10.3390/nu13103457] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/09/2021] [Revised: 09/19/2021] [Accepted: 09/26/2021] [Indexed: 11/16/2022] Open
Abstract
While the contributing factors leading to endometriosis remain unclear, its clinical heterogeneity suggests a multifactorial causal background. Amongst others, caffeine has been studied extensively during the last decade as a putative contributing factor. In this systematic review and meta-analysis, we provide an overview/critical appraisal of studies that report on the association between caffeine consumption and the presence of endometriosis. In our search strategy, we screened PubMed and Scopus for human studies examining the above association. The main outcome was the relative risk of endometriosis in caffeine users versus women consuming little or no caffeine (<100 mg/day). Subgroup analyses were conducted for different levels of caffeine intake: high (>300 mg/day) or moderate (100–300 mg/day). Ten studies were included in the meta-analysis (five cohort and five case-control studies). No statistically significant association was observed between overall caffeine consumption and risk for endometriosis (RR 1.12, 95% confidence interval (CI) 0.97–1.28, I2 = 70%) when compared to little or no (<100 mg/day) caffeine intake. When stratified according to level of consumption, high intake was associated with increased risk of endometriosis (RR 1.30, 95%CI 1.04–1.63, I2 = 56%), whereas moderate intake did not reach nominal statistical significance (RR 1.18, 95%CI 0.99–1.40, I2 = 37%). In conclusion, caffeine consumption does not appear to be associated with increased risk for endometriosis. However, further research is needed to elucidate the potential dose-dependent link between caffeine and endometriosis or the probable role of caffeine intake as a measurement of other unidentified biases.

Abstract
PURPOSE OF REVIEW Intrinsic factors, such as age, weight and lifestyle habits, together with extrinsic factors, such as socioeconomic level, must be considered when it comes to reproductive healthcare. Over the last few years, studies that attempt to respond to the participation and interaction of these factors in subfertility have been published; however, some questions remain unanswered. RECENT FINDINGS Although there are little modifiable factors for women, it is possible to influence other factors, such as behavioural or cultural factors in order to minimize fertility problems; however, they are often highly influenced by each other. SUMMARY Advanced age, obesity, sedentary lifestyle, alcohol, tobacco and other compounds, have a clearly negative effect and may extend time-to-pregnancy, although the responsible mechanisms and the magnitude of the detriment that they produce in the reproductive health are yet to be studied. Economic context and new environmental factors are a current challenge for reproductive health too.

Abstract
RATIONALE, AIMS, AND OBJECTIVES Polycystic ovarian syndrome (PCOS) is a serious health problem that affects women of all ages worldwide, including their quality of life (QOL). Interventions on lifestyle modification can be a suitable therapy. This study aimed to evaluate the effect of a PCOS pharmaceutical care service on QOL for women diagnosed with PCOS living in Syria (a country affected by war) and Jordan (non-war-zone country). METHODS PCOS women from both Syria and Jordan with age above 16 years were recruited in the study. Women randomly allocated into active group received an educational intervention by the pharmacist (via oral and written educational module) with special focus on diet and exercise. Women allocated to the control group did not receive the educational intervention. Both groups were followed for 4 months. Women in both groups completed the QOL questionnaire at both baseline and end of study. Multiple-regression analysis was performed to identify factors associated with change in QOL scores across the study. RESULTS PCOS women (n = 118) from both Syria (n = 60) and Jordan (n = 58) were recruited. Unlike control group patients, QOL was significantly improved in the active group at the end of the study for Syrian (102.75 vs 118.50, P < 0.001) and Jordanian women (95.31 vs 112.67, P < 0.001). Study group (active versus control) and difference in anxiety scores across the study were the only independent variables that showed association with the dependent variable, difference in QOL mean scores across the study period. CONCLUSION A pharmacist led intervention on lifestyle modification delivered to PCOS women led to positive effects on QOL scores. The intervention was successful in Syria and Jordan. This highlights the significant role that pharmacists can play in improving the life of women with PCOS whether living in war or non-war-zone countries.

Abstract
BACKGROUND Considerable interest has been gathered on the relevant impact of preventable factors, including incorrect lifestyle and unhealthy habits, on female fertility. Smoking, alcohol and addictive drugs consumption represent a major concern, given the broad range of diseases which might be favored or exacerbated by these dependable attitudes. Despite the well-characterized effects of prenatal exposure on pregnancy outcomes and fetus health, a substantial proportion of women of reproductive age is still concerned with these habits. At present, the impact of smoke, alcohol and addictive drugs on women fertility, and, particularly, the specific targets and underlying mechanisms, are still poorly understood or debated, mainly due to the scarcity of well-designed studies, and to numerous biases. OBJECTIVE The current review will provide a comprehensive overview of clinical and experimental studies in humans and animals addressing the impact of smoke, alcohol and addictive drugs on female fertility, by also embracing effects on ovary, oviduct, and uterus, with particular reference to primary endpoints such as ovarian reserve, steroidogenesis, ovulation and menstrual cycle, oviduct function and uterus receptivity and implantation. A brief focus on polycystic ovary syndrome and endometriosis will be also included. METHODS A Pubmed literature search was performed with selected keywords; articles were individually retrieved by each author. No limitation was set for publication date. Articles in languages other than English were excluded. Additional articles were retrieved from references list of selected manuscripts. RESULTS AND CONCLUSIONS Currently, the most consistent evidences of a detrimental effect of smoke, alcohol and addictive drugs on specific domains of the female reproductive function are provided by experimental studies in animals. Overall, clinical studies suggest that smoking is associated to decreased fertility, although causal inference should be further demonstrated. Studies addressing the effect of alcohol consumption on female fertility provide conflicting results, although the majority reported lack of a correlation. Extremely scarce studies investigated the effects of addictive drugs on female fertility, and the specific actions of selected drugs have been difficult to address, due to multidrug consumption.

Abstract
Cannabinoids comprise a broad group of psychoactive substances that activate endogenous cannabinoid (EC) receptors (ie, CB1 R and CB2 R), altering neurotransmitter release in the brain. The importance of their regulatory role in different biological processes has prompted the development of synthetic cannabinoids (SCs), substantially more potent than tetrahydrocannabinol (THC, the main psychoactive substance of cannabis). Although SCs were primarily designed given their therapeutic applications, their recreational use has become a major public health concern due to several reports of severe intoxications and deaths. SCs have favored increased popularity over recent years due to their intensified psychoactive effects, compared with THC, turning regular cannabis users into SCs. Among cannabinoid users (mainly young people), pregnant women and women of child-bearing potential (WoCBP) comprise particular risk groups, due to the potential onset of neurodevelopment disorders in the offspring (eg, schizophrenia and autism spectrum disorders). Understanding the role played by cannabinoids, and the potential action of emerging SCs in the regulation of the neuronal function, especially during neuronal development, thus assumes critical relevance. Here, we review the mechanistic regulation of neuronal processes, namely during neuronal development, by the endocannabinoid system. Most important, we further develop on the potential of SCs to modulate such mechanisms and subsequently disrupt proper neurodevelopment.

Abstract
BACKGROUND Epidemiological evidence remains equivocal on the associations between environmentally relevant levels of per-/polyfluoroalkyl substances (PFASs) and human semen quality. OBJECTIVES We aimed to test whether the potential effects on semen quality could be better observed when seminal PFAS levels were used as an exposure marker compared with serum PFAS levels. METHODS Matched semen and serum samples from 664 adult men were collected from a cross-sectional population in China from 2015 to 2016. Multiple semen parameters were assessed, along with measurement of 16 target PFASs in semen and serum. Partitioning between semen and serum was evaluated by the ratio of matrix-specific PFAS concentrations. Regression model results were expressed as the difference in each semen parameter associated with the per unit increase in the ln-transformed PFAS level after adjusting for confounders. RESULTS Perfluorooctanoate (PFOA), perfluorooctane sulfonate (PFOS), and emerging chlorinated polyfluorinated ether sulfonate (6:2 Cl-PFESA) were detected at their highest concentrations in both semen and serum, with median concentrations of 0.23, 0.10, and 0.06 ng/mL in semen, respectively, and a semen-to-serum ratio of 1.3:3.1. The between-matrix correlations of these PFAS concentrations were high (R=0.70-0.83). Seminal PFOA, PFOS, and 6:2 Cl-PFESA levels were significantly associated with a lower percentage of progressive sperm and higher percentage of DNA fragmentation (false discovery rate-adjusted p-values of<0.05). Associations between serum PFAS levels and semen parameters were generally statistically weaker, except for DNA stainability, which was more strongly associated with serum-based PFASs than with semen-based PFASs. CONCLUSIONS Our results suggest the potential for deleterious effects following exposure to 6:2 Cl-PFESA and other PFASs. Compared with serum PFAS levels, the much clearer association of seminal PFAS levels with semen parameters suggests its advantage in hazard assessment on semen quality, although the potential for confounding might be higher. Exposure measurements in target tissue may be critical in clarifying effects related to PFAS exposure. https://doi.org/10.1289/EHP4431.

Prevalence of anxiety and depression among women with Polycystic Ovary Syndrome living in war versus non-war zone countries: A randomized controlled trial assessing a pharmacist intervention. Res Social Adm Pharm 2019; 16:689-698. [PMID: 31420190 DOI: 10.1016/j.sapharm.2019.08.027] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/19/2018] [Revised: 07/22/2019] [Accepted: 08/08/2019] [Indexed: 11/23/2022]
Abstract
BACKGROUND Polycystic ovary syndrome (PCOS) is a serious health problem. In women experiencing PCOS, there are myriad physical and mental health consequences; anxiety/depression are commonly associated with this condition. Community pharmacists are in a pivotal position to identify and help women diagnosed with PCOS. OBJECTIVES To investigate the prevalence/severity of anxiety/depression among females diagnosed with PCOS living in Syria (a war-zone country) and Jordan (a non-war zone country). Secondly, to evaluate the impact of a pharmaceutical care service delivered by a clinical pharmacist on participants' anxiety/depression severity. METHODS Females, diagnosed with PCOS above the age of 16, were recruited into the study and randomly allocated into either the active or the control group. The active group participants received a PCOS pharmaceutical care service. This service involved the provision of verbal and written educational materials, with a special focus on diet and exercise. The control group participants received only standard counseling. Both groups were followed up for four months. All participants completed the Beck Anxiety Inventory and the Beck Depression Inventory at baseline and follow-up. RESULTS Data from study participants (n = 118) from both Syria (n = 60) and Jordan (n = 58) highlighted a high prevalence of anxiety (Syria = 95% vs. Jordan = 98%) and depression (Syria = 83% vs. Jordan = 65%). At follow-up, active group participants, from both countries, showed significant improvements in anxiety and depression mean scores (anxiety: Syria = 34.97 ± 14.8 vs. 30.47 ± 14.3, p < 0.001; Jordan = 26.93 ± 13.7 vs. 23.37 ± 15.2, p < 0.001; depression: Syria = 26.53 ± 12.6 vs. 22.93 ± 12.2, p < 0.001; Jordan = 17.70 ± 11.0 vs. 15.76 ± 11.1, p = 0.049). No significant improvements were evident for control group participants from either countries. CONCLUSION Prevalence of anxiety/depression for females with PCOS living in Syria and in Jordan is high and calls for special attention by healthcare specialists and policymakers in both countries. Females, who received the PCOS pharmaceutical care service, showed significant improvements in anxiety/depression scores. Improvements were similar in both countries.

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 independently predict quantifiable measures of the impact of marijuana use. The main outcome measures were sperm motility, total motile spermatozoa and morphology. RESULTS Overall, 47% of the participants reported marijuana use with 21% of these men reporting recent use. Regression analyses showed that recent use and users of large quantities of marijuana were 2.6 times (aOR = 2.6; 95% CI, 1.0-6.8, p = 0.044) and 4.3 times (aOR = 4.3; 95% CI, 1.1-15.9, p = 0.030) at greater risk of being diagnosed with abnormal motility (asthenozoospermia). Additionally, moderate quantity users were 3.4 times (aOR = 3.4; 95% CI, 1.5-7.9, p = 0.004) more likely to be diagnosed with abnormal morphology (teratozoospermia). DISCUSSION AND CONCLUSION Recent use of marijuana as well as moderate to large quantities had an impact on sperm motility and morphology in men being investigated for infertility. We recommend therefore that men undergoing fertility investigations be routinely asked about their recreational use of marijuana and in particular recent and heavy users counselled to stop.

Abstract
Twelve persistent organic pollutants (POPs) were measured in 11 tissue samples from a pregnant sperm whale stranded on the Huizhou coast of the South China Sea, China, in March 2017. POPs were found to be more concentrated in the irrigated tissues such as placenta, ovary, mammary gland, and liver than the less irrigated tissues such as epidermis. High POP levels detected in the placenta might result in abnormal hormone secretion in the placenta, which would affect the unborn offspring. We hypothesized that ovary is potentially vulnerable to the exposure of higher contaminant levels. The PAH concentrations were higher in the lung than in other tissues, which suggest that PAH levels in the lung were breath-dependent in the sperm whale. The concentrations of POPs except PAHs in the sperm whale blubber were lower than those in the same species in the Northern Hemisphere and were comparable to or lower than those in the same species in the Southern Hemisphere.

Yen CF, Kim MR, Lee CL. Epidemiologic Factors Associated with Endometriosis in East Asia. Gynecol Minim Invasive Ther 2019; 8:4-11. [PMID: 30783582 PMCID: PMC6367920 DOI: 10.4103/gmit.gmit_83_18] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/29/2018] [Revised: 11/15/2018] [Accepted: 11/26/2018] [Indexed: 01/11/2023] Open
Abstract
Aim With a perplexing pathogenesis and an incidence rate of approximately 10% among women of reproductive age, endometriosis affects more women in Asia than in any other continent in the world. This paper reviews the available data on the epidemiology and risk factors associated with endometriosis in East Asia. Methods Included studies were published between January 2000 and December 2016. Articles were required to include East Asian patients with a diagnosis of endometriosis and to study epidemiology, such as the prevalence and/or incidence, associated with inherited, environmental, and/or lifestyle factors. A total of 65 candidate articles were retrieved and 22 were included in the final review. Results Only one study provided an estimate of prevalence (6.8%). Short menstrual cycle, family history of endometriosis, and some genetic polymorphisms are associated with the risk of developing endometriosis. Smoking, lower body mass index, and lower parity associated with increased risk of endometriosis were suggested as modifiable factors. Limitations of this study include the poor quality of data identified, and the language barriers behind the study retrieval. Conclusions Data on the epidemiology of endometriosis in the East Asian populations are limited. The available data that examine potential genetic factors do not unveil whether such factors directly contribute to the increased risk of endometriosis. Further extensive studies on endometriosis in Asian women are required to improve the management of this disease.

Blastocyst-Derived Stem Cell Populations under Stress: Impact of Nutrition and Metabolism on Stem Cell Potency Loss and Miscarriage. Stem Cell Rev Rep 2018; 13:454-464.

Abstract
Data from in vitro and in vivo models suggest that malnutrition and stress trigger adaptive responses, leading to small for gestational age (SGA) blastocysts with fewer cell numbers. These stress responses are initially adaptive, but become maladaptive with increasing stress exposures. The common stress responses of the blastocyst-derived stem cells, pluripotent embryonic and multipotent placental trophoblast stem cells (ESCs and TSCs), are decreased growth and potency, and increased, imbalanced and irreversible differentiation. SGA embryos may fail to produce sufficient antiluteolytic placental hormone to maintain corpus luteum progesterone secretion that provides nutrition at the implantation site. Myriad stress inputs for the stem cells in the embryo can occur in vitro during in vitro fertilization/assisted reproductive technology (IVF/ART) or in vivo. Paradoxically, stresses that diminish stem cell growth lead to a higher level of differentiation simultaneously which further decreases ESC or TSC numbers in an attempt to functionally compensate for fewer cells. In addition, prolonged or strong stress can cause irreversible differentiation. Resultant stem cell depletion is proposed as a cause of miscarriage via a "quiet" death of an ostensibly adaptive response of stem cells instead of a reactive, violent loss of stem cells or their differentiated progenies.

Abstract
This study aimed to assess the association between aryl hydrocarbon receptor (AhR) rs2066853 gene polymorphism with infertile oligoasthenoteratozoospermic (OAT) men and seminal oxidative stress (OS). A total of 170 Egyptian men were allocated according to their semen analysis into fertile normozoospermic controls (n = 50) and infertile OAT men (n = 120). They were subjected to history taking, clinical examination, semen analysis, estimation of seminal glutathione peroxidase (GPx), and malondialdehyde (MDA). AhR rs2066853 gene polymorphism was identified in the blood by PCR-RFLP. Comparing infertile OAT men with fertile controls, AhR rs2066853 genotypes showed decreased prevalence for wild homozygous genotype GG (35.8 vs 56%) and for heterozygous genotype GA (17.5 vs 30%) and an increased prevalence for homozygous genotype AA (46.7 vs 14%). Distribution of alleles of AhR rs2066853 among OAT men compared with fertile men showed decreased prevalence of G allele (44.6 vs 71%) and an increased prevalence of A allele (55.4 vs 29%). Seminal MDA demonstrated significant increase whereas seminal GPx demonstrated significant decrease in cases with AA and GA/AA genotypes compared to cases with GG genotype. It is concluded that there is a significant association between AhR rs2066853 genotype polymorphism with decreased sperm parameters as well as increased seminal oxidative stress in infertile OAT men.

Abstract
The nonspecific PDE inhibitors, particularly the methylxanthines: caffeine, pentoxifylline (PTX), and theophylline, are known to stimulate sperm motility in vitro and have been used to treat sperm prior to insemination. The in vivo effects are less dramatic. A beneficial effect of caffeine, which is a constituent of some medications, remains controversial. Very high doses of caffeine do have negative effects on fertility endpoints in men and experimental species. The specific PDE5 inhibitors, particularly sildenafil and tadalafil, are prescribed for erectile dysfunction, as well as pulmonary hypertension, lower urinary tract symptoms, and premature ejaculation. PDE5 is expressed throughout the contractile tissues of the male reproductive tract, generally increasing contractility. Some PDE5 inhibitors tend to increase circulating testosterone levels somewhat. For short-term exposure consistent with use prior to intercourse, there appears to be minimal effects on semen quality. Several large, randomized controlled trials (RCTs) in healthy men have not found adverse effects of long-term use of these drugs on semen quality. RCTs in infertile men have demonstrated a modest increase in semen quality. Animal studies at human equivalent doses (HED) have produced similar results in young males, but a study in aging male rats found progressive decreases in epididymal sperm quality accompanied by consistent degeneration of the seminal tubules suggesting that studies in older men might be warranted. A concerning study in mice found lower fertilization rates in males treated with HED of sildenafil and mated the next day to untreated females than for control males. Fertility studies in humans are needed.

Abstract
Hypoxis hemerocallidea is used in traditional medicine in South Africa, for the treatment of male reproductive ailments and various chronic illnesses. Despite chronic use, its effects on male reproductive system are unknown. Male Wistar rats were treated orally daily for 28 (n = 18) and 56 days (n = 18). Treatment groups (n = 6/group) per treatment period were as follows: untreated control, 150 mg/kg and 300 mg/kg 70% ethanolic extract of H. hemerocallidea. Sexual behaviour observations were performed on days 17 and 42 of the study. Sperm, biochemical and testicular histopathological studies were carried out. Arousal and libido and serum testosterone increased after 56 days of treatment. There was an increase in epididymal sperm count at both treatment doses, with the 300 mg/kg dose showing a higher sperm count (p < .05) compared to the 150 mg/kg treatment group. The higher 300 mg/kg dose also showed an increase (p < .05) in sperm motility after 56 days of treatment. Histology showed an increase in germinal layer thickness, consistent with the observed increase in sperm count. Testicular oxidative status improved after 56 days of treatment. Results suggest that chronic treatment with H. hemerocallidea may improve male sexual function and fertility parameters and may protect testes from oxidative damage.

Abstract
Background In order to empower infertile individuals and provide high quality patient-centered infertility care,
it is necessary to recognize and meet infertile individuals’ educational needs. This study aims to examine infertility patients’ knowledge
and subsequently their education needs given their attitudinal approach to infertility
education in terms of patients who undergo assisted reproduction treatment. Materials and Methods This descriptive study enrolled 150 subjects by conveni-
ence sampling of all patients who received their first assisted reproductive treatment
between July and September 2015 at a referral fertility clinic, Royan Institute, Tehran, Iran. We used a questionnaire that measured fertility and infertility information
(8 questions) as well as attitude toward education on the causes and treatment of
infertility (5 questions). Chi-square, independent sample t test, and one way ANOVA
analyses were conducted to examine differences by sex. P<0.05 was considered statistically significant. Results Total mean knowledge was 3.08 ± 0.99. Clients’ responses indicated that
the highest mean knowledge scores related to knowledge of factors that affected
pregnancy (3.97 ± 1.11) and infertility treatment (3.97 ± 1.16). The lowest mean
knowledge scores related to knowledge of the natural reproductive cycle (2.96 ±
1.12) and anatomy of the genital organs (2.94 ± 1.16). Most females (92.1%) and
males (83.3%) were of the opinion that infertility education programs should include
causes of infertility and types of treatment associated with diagnostic and laboratory
procedures. No statistically significant difference existed between male and female
participants (P=0.245). Conclusion Most participants in this study expressed awareness of factors that affect
pregnancy and infertility treatment. It is imperative to educate and empower infertile
individuals who seek reproduction treatment in terms of infertility causes and types
of treatment, as well as diagnostic and laboratory procedures to enable them to make
informed decisions about their assisted reproductive procedures.

Abstract
Sperm count, morphology, and motility have been reported to be predictive of pregnancy, although with equivocal basis prompting some authors to question the prognostic value of semen analysis. To assess the utility of including semen quality data in predicting conception delay or requiring >6 cycles to become pregnant (referred to as conception delay), we utilized novel data-driven analytic techniques in a pre-conception cohort of couples prospectively followed up for time-to-pregnancy. The study cohort comprised 402 (80%) male partners who provided semen samples and had time-to-pregnancy information. Female partners used home pregnancy tests and recorded results in daily journals. Odds ratios (OR), false discovery rates, and 95% confidence intervals (CIs) for conception delay (time-to-pregnancy > 6 cycles) were estimated for 40 semen quality phenotypes comprising 35 semen quality endpoints and 5 closely related fecundity determinants (body mass index, time of contraception, lipids, cotinine and seminal white blood cells). Both traditional and strict sperm phenotype measures were associated with lower odds of conception delay. Specifically, for an increase in percent morphologically normal spermatozoa using traditional methods, we observed a 40% decrease in conception delay (OR = 0.6, 95% CI = 0.50, 0.81; p = 0.0003). Similarly, for an increase in strict criteria, we observed a 30% decrease in odds for conception delay (OR = 0.7, 95% CI = 0.52, 0.83; p = 0.001). On the other hand, an increase in percent coiled tail spermatozoa was associated with a 40% increase in the odds for conception delay (OR = 1.4, 95% CI = 1.12, 1.75; p = 0.003). However, our findings suggest that semen phenotypes have little predictive value of conception delay (area under the curve of 73%). In a multivariate model containing significant semen factors and traditional risk factors (i.e. age, body mass index, cotinine and ever having fathered a pregnancy), there was a modest improvement in prediction of conception delay (16% increase in area under the curve, p < 0.0002).

Abstract
CONTEXT The impact of early life events on testicular function in adulthood is not well understood. OBJECTIVE To study the early influences of fetal growth, exposures to cigarette smoke in utero and cord blood estrogens, and the influences of growth and adiposity in childhood through adolescence; on testicular function in adulthood. DESIGN Male members of the Western Australian Pregnancy Cohort (Raine) were contacted at 20-22 years of age. Of 913 contacted, 423 (56%) agreed to participate; 404 underwent a testicular ultrasound, 365 provided a semen sample, and reproductive hormones were measured (384). Fetal growth measurements (n = 137), umbilical cord estrogen concentrations (n = 128), cord testosterone (T) (n = 125), and child-adulthood growth charts (n = 395) were available. RESULTS Median sperm output for the 18.6% of men exposed in utero to smoking was lower than nonexposed (82.4 × 10(6) vs 123.1 × 10(6); P = .029). Sperm output in adulthood was inversely correlated with cord serum estradiol (P = .019) and estrone (P = .018). The sperm output of men whose cord blood estradiol and estrone were less than 50th percentile vs more than 50th percentile was 191.1 × 10(6) vs 100.5 × 10(6) (P = .002) and 190.0 × 10(6) vs 106.0 × 10(6) (P = .012), respectively. Men with favorable fetal growth patterns in utero were less likely to have total motile sperm counts within the lowest quartile (P = .011), and men born prematurely had reduced serum T levels in adulthood (13.4 vs 16.6nmol/L, P = .024). Consistent height above the 50th percentile for age through childhood was associated with larger adult mean testicular volume (P < .001). Optimal body mass index trajectory through childhood and adolescence was associated with larger testicular volume (P = .009) and higher serum inhibin B (P = .010) and T (P = .003) in adulthood. CONCLUSIONS Exposures to maternal smoking and higher cord blood estrogens at delivery were associated with a reduced sperm output in adulthood. Optimal adult testicular function depends on being born at or above average weight, and maintaining optimal growth and adiposity into adulthood.

Abstract
OBJECTIVE To investigate to what extent alcohol consumption affects female fecundability. DESIGN Prospective cohort study. SETTING Denmark, 1 June 2007 to 5 January 2016. PARTICIPANTS 6120 female Danish residents, aged 21-45 years, in a stable relationship with a male partner, who were trying to conceive and not receiving fertility treatment. MAIN OUTCOME MEASURES Alcohol consumption was self reported as beer (330 mL bottles), red or white wine (120 mL glasses), dessert wine (50 mL glasses), and spirits (20 mL) and categorized in standard servings per week (none, 1-3, 4-7, 8-13, and ≥14). Participants contributed menstrual cycles at risk until the report of pregnancy, start of fertility treatment, loss to follow-up, or end of observation (maximum 12 menstrual cycles). A proportional probability regression model was used to estimate fecundability ratios (cycle specific probability of conception among exposed women divided by that among unexposed women). RESULTS 4210 (69%) participants achieved a pregnancy during follow-up. Median alcohol intake was 2.0 (interquartile range 0-3.5) servings per week. Compared with no alcohol consumption, the adjusted fecundability ratios for alcohol consumption of 1-3, 4-7, 8-13, and 14 or more servings per week were 0.97 (95% confidence interval 0.91 to 1.03), 1.01 (0.93 to 1.10), 1.01 (0.87 to 1.16) and 0.82 (0.60 to 1.12), respectively. Compared with no alcohol intake, the adjusted fecundability ratios for women who consumed only wine (≥3 servings), beer (≥3 servings), or spirits (≥2 servings) were 1.05 (0.91 to1.21), 0.92 (0.65 to 1.29), and 0.85 (0.61 to 1.17), respectively. The data did not distinguish between regular and binge drinking, which may be important if large amounts of alcohol are consumed during the fertile window. CONCLUSION Consumption of less than 14 servings of alcohol per week seemed to have no discernible effect on fertility. No appreciable difference in fecundability was observed by level of consumption of beer and wine.

Why young people's substance use matters for global health. Lancet Psychiatry 2016; 3:265-79.

Abstract
During puberty, when young people are completing their education, transitioning into employment, and forming longer-term intimate relationships, a shift in emotional regulation and an increase in risky behaviour, including substance use, is seen. This Series paper considers the potential effects of alcohol, tobacco, and illicit drug use during this period on: social, psychological, and health outcomes in adolescence and young adulthood; role transitions, and later health and social outcomes of regular substance use initiated in adolescence; and the offspring of young people who use substances. We sourced consistent support for causal relations between substance use and outcomes and evidence of biological plausibility from different but complementary research designs. Many adverse health and social outcomes have been associated with different types of substance use. The major challenge lies in deciding which are causal. Furthermore, qualitatively different harms are associated with different substances, differences in life stage when these harms occur, and the quality of evidence for different substances and health outcomes varies substantially. The preponderance of evidence comes from a few high-income countries, thus whether the same social and health outcomes would occur in other countries and cultures is unclear. Nonetheless, the number of harms that are causally related to substance use in young people warrant high-quality research design interventions to prevent or ameliorate these harms.

Abstract
BACKGROUND Worrying trends regarding human reproductive endpoints (e.g. semen quality, reproductive cancers) have been reported and there is growing circumstantial evidence for a possible causal link between these trends and exposure to endocrine disrupting chemicals (EDCs). However, there is a striking lack of human data to fill the current knowledge gaps. To answer the crucial questions raised on human reproductive health, there is an urgent need for a reproductive surveillance system to be shared across countries. METHODS A multidisciplinary network named HUman Reproductive health and Global ENvironment Network (HURGENT) was created aiming at designing a European monitoring system for reproductive health indicators. Collaborative work allowed setting up the available knowledge to design such a system. Furthermore we conducted an overview of 23 potential indicators, based upon a weight of evidence (WoE) approach according to their potential relation with EDC exposure. RESULTS The framework and purposes of the surveillance system are settled as well as the approach to select suitable reproductive indicators. The indicators found with the highest scores according to the WoE approach are prostate and breast cancer incidence, sex ratio, endometriosis and uterine fibroid incidence, indicators related to the testicular dysgenesis syndrome, precocious puberty incidence and reproductive hormone levels. CONCLUSION Not only sentinel health endpoints, but also diseases with high burdens in public health are highlighted as prior indicators in the context of EDC exposure. Our work can serve as a basis to construct, as soon as possible, the first multi-country reproductive monitoring system.

Abstract
Cadmium (Cd) is a heavy metal with toxicant to reproductive functions. The aim of this study was to explore the effects of environmental exposure to Cd on human semen quality. A total of 587 men from the general population, aged from 20 to 59 years old, and without occupational exposure to Cd were recruited from three provinces in China to participate in the study. The median of serum Cd was 1.9 μg/L (P25-P75:1.1-2.9). In case Cd was less than or equal to 6.3 μg/L (P95) and the semen parameters were logarithmically transformed, the inverse associations between Cd and semen volume (-0.03 ± 0.007), progressive motility (-0.01 ± 0.004), and sperm morphology (-0.04 ± 0.004) were found across the whole group, after adjusting for age group, occupation, season of semen sample collection, abstinence intervals, smoking, alcohol drinking, and body mass index. Our findings indicate that higher Cd may reduce the semen volume, progressive motility, and morphology among men without occupational exposure to Cd.

Abstract
Decline of semen quality in past decades is suggested to be potentially associated with environmental and sociopsychobehavioral factors, but data from population-based cohort studies is limited. The male reproductive health in Chongqing College students (MARHCS) study was established in June 2013 as a perspective cohort study that recruited voluntary male healthy college students from 3 universities in Chongqing. The primary objectives of the MARHCS study are to investigate the associations of male reproductive health in young adults with sociopsychobehavioral factors, as well as changes of environmental exposure due to the relocation from rural campus (in University Town) to metro-campus (in central downtown). A 93-item questionnaire was used to collect sociopsychobehavioral information in manner of interviewer-interviewing, and blood, urine and semen samples were collected at the same time. The study was initiated with 796 healthy young men screened from 872 participants, with a median age of 20. About 81.8% of this population met the WHO 2010 criteria on semen quality given to the 6 routine parameters. Decreases of 12.7%, 19.8%, and 17.0%, and decreases of 7.7%, 17.6%, and 14.7% in total sperm count and sperm concentration, respectively, were found to be associated with the tertiles of accumulated smoking amount. Fried food consumption (1-2 times/wk or ≥3 times/wk vs nonconsumers) was found to be associated with decreased total sperm count (10.2% or 24.5%) and sperm concentration (13.7% or 17.2%), respectively. Coffee consumption was found to be associated with increased progressive and nonprogressive motility of 8.9% or 15.4% for subjects consuming 1-2 cups/wk or ≥3 cups/wk of coffee, respectively. Cola consumption appeared an association with decreased semen volume at 4.1% or 12.5% for 1-2 bottles/wk or ≥3 bottles/wk. A cohort to investigate the effects of environmental/sociopsychobehavioral factors act on semen quality was successfully set up. We found smoking, coffee/cola/fried foods consumption to be significantly associated with semen quality from the baseline investigation.

Abstract
BACKGROUND The use of cannabis, or marijuana, for medicinal purposes is deeply rooted though history, dating back to ancient times. It once held a prominent position in the history of medicine, recommended by many eminent physicians for numerous diseases, particularly headache and migraine. Through the decades, this plant has taken a fascinating journey from a legal and frequently prescribed status to illegal, driven by political and social factors rather than by science. However, with an abundance of growing support for its multitude of medicinal uses, the misguided stigma of cannabis is fading, and there has been a dramatic push for legalizing medicinal cannabis and research. Almost half of the United States has now legalized medicinal cannabis, several states have legalized recreational use, and others have legalized cannabidiol-only use, which is one of many therapeutic cannabinoids extracted from cannabis. Physicians need to be educated on the history, pharmacology, clinical indications, and proper clinical use of cannabis, as patients will inevitably inquire about it for many diseases, including chronic pain and headache disorders for which there is some intriguing supportive evidence. OBJECTIVE To review the history of medicinal cannabis use, discuss the pharmacology and physiology of the endocannabinoid system and cannabis-derived cannabinoids, perform a comprehensive literature review of the clinical uses of medicinal cannabis and cannabinoids with a focus on migraine and other headache disorders, and outline general clinical practice guidelines. CONCLUSION The literature suggests that the medicinal use of cannabis may have a therapeutic role for a multitude of diseases, particularly chronic pain disorders including headache. Supporting literature suggests a role for medicinal cannabis and cannabinoids in several types of headache disorders including migraine and cluster headache, although it is primarily limited to case based, anecdotal, or laboratory-based scientific research. Cannabis contains an extensive number of pharmacological and biochemical compounds, of which only a minority are understood, so many potential therapeutic uses likely remain undiscovered. Cannabinoids appear to modulate and interact at many pathways inherent to migraine, triptan mechanisms ofaction, and opiate pathways, suggesting potential synergistic or similar benefits. Modulation of the endocannabinoid system through agonism or antagonism of its receptors, targeting its metabolic pathways, or combining cannabinoids with other analgesics for synergistic effects, may provide the foundation for many new classes of medications. Despite the limited evidence and research suggesting a role for cannabis and cannabinoids in some headache disorders, randomized clinical trials are lacking and necessary for confirmation and further evaluation.

Abstract
BACKGROUND The relation between persistent environmental chemicals and semen quality is evolving, although limited data exist for men recruited from general populations. OBJECTIVES We examined the relation between perfluorinated chemicals (PFCs) and semen quality among 501 male partners of couples planning pregnancy. METHODS Using population-based sampling strategies, we recruited 501 couples discontinuing contraception from two U.S. geographic regions from 2005 through 2009. Baseline interviews and anthropometric assessments were conducted, followed by blood collection for the quantification of seven serum PFCs (perfluorosulfonates, perfluorocarboxylates, and perfluorosulfonamides) using tandem mass spectrometry. Men collected a baseline semen sample and another approximately 1 month later. Semen samples were shipped with freezer packs, and analyses were performed on the day after collection. We used linear regression to estimate the difference in each semen parameter associated with a one unit increase in the natural log-transformed PFC concentration after adjusting for confounders and modeling repeated semen samples. Sensitivity analyses included optimal Box-Cox transformation of semen quality end points. RESULTS Six PFCs [2-(N-methyl-perfluorooctane sulfonamido) acetate (Me-PFOSA-AcOH), perfluorodecanoate (PFDeA), perfluorononanoate (PFNA), perfluorooctane sulfonamide (PFOSA), perfluorooctane sulfonate (PFOS), and perfluorooctanoic acid (PFOA)] were associated with 17 semen quality end points before Box-Cox transformation. PFOSA was associated with smaller sperm head area and perimeter, a lower percentage of DNA stainability, and a higher percentage of bicephalic and immature sperm. PFDeA, PFNA, PFOA, and PFOS were associated with a lower percentage of sperm with coiled tails. CONCLUSIONS Select PFCs were associated with certain semen end points, with the most significant associations observed for PFOSA but with results in varying directions.

Abstract
BACKGROUND Infertility patients are increasingly using complementary and alternative medicine (CAM) to supplement or replace conventional fertility treatments. The objective of this study was to determine the roles of CAM practitioners in the support and treatment of infertility. METHODS Ten semi-structured interviews were conducted in Ottawa, Canada in 2011 with CAM practitioners who specialized in naturopathy, acupuncture, traditional Chinese medicine, hypnotherapy and integrated medicine. RESULTS CAM practitioners played an active role in both treatment and support of infertility, using a holistic, interdisciplinary and individualized approach. CAM practitioners recognized biological but also environmental and psychosomatic determinants of infertility. Participants were receptive to working with physicians, however little collaboration was described. CONCLUSIONS Integrated infertility patient care through both collaboration with CAM practitioners and incorporation of CAM's holistic, individualized and interdisciplinary approaches would greatly benefit infertility patients.

Abstract
There is strong evidence indicating that disease in adult humans stems from a combination of genetic and environmental factors. A problem in identifying environmental factors is that subacute exposures during early life are often unnoticed, or exposures are variable among a diverse population. This leads to a confusing pattern in adulthood. An additional problem in following exposure effects in humans is the length of time needed to study outcomes spanning a human generation. We have recently developed a zebrafish model for studying the effects of sublethal juvenile exposure to 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD, dioxin). Although the initial exposure produces no effect at the time, we find skeletal and reproductive defects in adulthood and into subsequent generations. The short generation time of zebrafish along with the ability to maintain large cohorts of exposed individuals and their offspring allows us to overcome variation in exposure and genetic background. Here we describe progress in studying TCDD as an endocrine and developmental disruptor, and our results showing adult consequences of early exposure.

Shedding light on the controversy surrounding the temporal decline in human sperm counts: a systematic review. ScientificWorldJournal 2014; 2014:365691.

Abstract
We systematically examined the evidence of declining sperm counts and the hypothesis that an increased exposure to environmental pollutants is responsible for such decline. Search engines, including PUBMED, MEDLINE, EMBASE, BIOSIS, and Cochrane library, were used to identify epidemiologic studies published from 1985 to 2013. We concluded that there is no enough evidence to confirm a worldwide decline in sperm counts. Also, there seems to be no scientific truth of a causative role for endocrine disruptors in the temporal decline of sperm production. Such assumptions are based on few meta-analyses and retrospective studies, while other well-conducted researches could not confirm these findings. We acknowledge that difficult-to-control confounding factors in the highly variable nature of semen, selection criteria, and comparability of populations from different time periods in secular-trend studies, the quality of laboratory methods for counting sperm, and apparently geographic variations in semen quality are the main issues that complicate the interpretation of the available evidence. Owing to the importance of this subject and the uncertainties still prevailing, there is a need not only for continuing monitoring of semen quality, reproductive hormones, and xenobiotics, but also for a better definition of fecundity.

Abstract
2,3,7,8 Tetrachlorodibenzo-p-dioxin (TCDD) has been associated with many disease states in humans. A rising concern is that exposure early in life can lead to adult toxicity and toxicity in subsequent generations. Juvenile zebrafish exposed to TCDD (50 pg/ml in water; 1 h exposure) at 3 and 7 weeks post fertilization showed toxicity only later in adulthood. We have maintained the offspring of these exposed F₀ fish to determine whether we could find adverse affects in the next two generations of F₁ and F₂ offspring. TCDD exposure produced a significantly higher female:male ratio in all three generations. Scoliosis-like axial skeleton abnormalities, not normally observed in controls, were present in the F₁ and F₂ generations descended from the treated F₀ founders. Egg release and fertilization success were reduced in the TCDD lineage F₁ and F₂ generations. This reduction in fertility in the TCDD lineage F₂ generation could be attributed to alterations in the F₂ males. Using zebrafish as a model allowed the simultaneous maintenance of different generations with relatively small space and costs. The zebrafish showed clear signs of transgenerational responses persisting into generations never directly exposed to TCDD.

Abstract
BACKGROUND Awareness of infertility risk factors is an essential first step to safeguard future fertility. Whereas several studies have examined university students' awareness of female fertility and related risk factors, the topic of male infertility has not been well examined. The objective of this study was to assess young men and women's awareness, knowledge and perceptions of infertility, male and female infertility risk factors and assisted reproductive technologies (ART). METHODS Semi-structured interviews were conducted in 2008 with a multi-ethnic sample of sixteen male and twenty-three female Ottawa university students, followed by qualitative data analysis to identify major themes. Interview topics included awareness of male and female infertility risk factors, infertility diagnosis/treatments and personal options in the event of future infertility. RESULTS Participants were generally familiar with infertility as a biomedical health problem, could identify sex-specific risk factors but overestimated fertility of women in their thirties and ART success rates. Reproductive health knowledge gaps and confusion of the physiological life-stage of menopause with infertility were apparent. Most participants would pursue in vitro fertilization or international adoption in the event of personal infertility. Some participants wished to use a 'natural' approach and were concerned with potential side effects of ART-related medications. CONCLUSIONS The general awareness of infertility in young adults is promising and supports the potential uptake for health promotion of fertility preservation. This study underscores the continued need for comprehensive sexual and reproductive health education and promotion for adolescents and young adults.

Abstract
BACKGROUND Because endometriosis is diagnosed predominantly in young women, exposures occurring during childhood or adolescence may have a major impact on the disease. However, potential risk factors during this time period have received little attention. Our objective was to investigate relationships between childhood and adolescent exposures and the risk of endometriosis. METHODS E3N is a prospective cohort of 98,995 French women aged 40-65 at enrollment in 1990. Follow-up questionnaires were sent every 2-3 years. Using a nested case-control design, we computed odds ratios (ORs) and 95% confidence intervals using unconditional logistic regression models. RESULTS A total of 2684 endometriosis cases were reported as surgically ascertained among the 75,918 included women. There were inverse relationships of endometriosis risk with menarcheal age (test for trend, P < 0.0001) and with menstrual cycle length before 17 years of age (test for trend, P = 0.06), whereas menstrual cycle regularity before 17 years of age was not associated with risk. There were modest associations of endometriosis risk with exposure to pet animals (OR = 1.12 [95% confidence interval =1.02-1.22]) or living in a farm for 3 or more consecutive months during childhood (1.12 [1.02-1.24]), although with no link to any specific type of farm animal. In addition, there were positive linear associations between endometriosis risk and level of indoor exposure to passive smoking during childhood (up to 1.34 [1.09-1.64] with several hours exposure a day), experiencing food deprivation during World War II (1.34 [0.94-1.91]), and walking activity at 8-15 years of age (1.17 [1.05-1.31] for 5+ hours a week). CONCLUSIONS This large study suggests that some exposures during childhood or adolescence may influence the risk of endometriosis. Further research is needed to confirm and better understand these relationships.

Abstract
BACKGROUND Saturated fat intake has been associated with both cardiovascular disease and cancer risk, and a newly published study found an association between saturated fat intake and a lower sperm concentration in infertile men. OBJECTIVE The objective was to examine the association between dietary fat intake and semen quality among 701 young Danish men from the general population. DESIGN In this cross-sectional study, men were recruited when they were examined to determine their fitness for military service from 2008 to 2010. They delivered a semen sample, underwent a physical examination, and answered a questionnaire comprising a quantitative food-frequency questionnaire to assess food and nutrient intakes. Multiple linear regression analyses were performed with semen variables as outcomes and dietary fat intakes as exposure variables, adjusted for confounders. RESULTS A lower sperm concentration and total sperm count in men with a high intake of saturated fat was found. A significant dose-response association was found, and men in the highest quartile of saturated fat intake had a 38% (95% CI: 0.1%, 61%) lower sperm concentration and a 41% (95% CI: 4%, 64%) lower total sperm count than did men in the lowest quartile. No association between semen quality and intake of other types of fat was found. CONCLUSIONS Our findings are of potentially great public interest, because changes in diet over the past decades may be part of the explanation for the recently reported high frequency of subnormal human sperm counts. A reduction in saturated fat intake may be beneficial for both general and reproductive health.

Abstract
BACKGROUND Canadian young adults may be at risk of future infertility due to the high incidence of sexually transmissible infections (STIs) in this population. Young adults' perceptions of environmental risks, including contaminants, STIs and lifestyle habits on infertility, have not been examined. We have therefore designed a qualitative study to explore risk perceptions, awareness and knowledge of common environmental risk factors for infertility in a multiethnic sample of young adults. METHODS Semistructured interviews were carried out with 40 university undergraduate students (16 men and 24 women) in Ottawa, Canada, followed by qualitative analysis of interview transcripts to identify major themes. RESULTS The following broad themes described participants' risk perceptions about infertility and (1) environmental contaminants: knowledge gaps, media reports and negative perception of chemicals; (2) STIs: superficial understanding of their role in infertility, general awareness, associations with sexual behaviours and knowledge gaps; and (3) lifestyle: protective benefits of healthy lifestyle, dose or exposure effects for smoking and alcohol, and knowledge gaps. Students demonstrated a superficial understanding of environmental risks, at times relying on media reports and anecdotal information to support their beliefs. CONCLUSIONS This next generation of potential infertility patients exhibits a general understanding of environmental risks to infertility; however, young adults are overly optimistic that healthy lifestyle behaviours will safeguard future fertility. STIs represent the most significant modifiable risk factors for this age group; a message that can be supported by sexual and reproductive health education and promotion with greater emphasis on the long-term outcomes of STIs, including infertility.

Abstract
Male infertility is a major cause of problems for many couples in conceiving a child. Recently, lifestyle pastimes such as alcohol, tobacco and marijuana have been shown to have further negative effects on male reproduction. The endocannabinoid system (ECS), mainly through the action of anandamide (AEA) and 2-arachidonoylglycerol (2-AG) at cannabinoid (CB1, CB2) and vanilloid (TRPV1) receptors, plays a crucial role in controlling functionality of sperm, with a clear impact on male reproductive potential. Here, sperm from fertile and infertile men were used to investigate content (through LC-ESI-MS), mRNA (through quantitative RT-PCR), protein (through Western Blotting and ELISA) expression, and functionality (through activity and binding assays) of the main metabolic enzymes of AEA and 2-AG (NAPE-PLD and FAAH, for AEA; DAGL and MAGL for 2-AG), as well as of their binding receptors CB1, CB2 and TRPV1. Our findings show a marked reduction of AEA and 2-AG content in infertile seminal plasma, paralleled by increased degradation: biosynthesis ratios of both substances in sperm from infertile versus fertile men. In addition, TRPV1 binding was detected in fertile sperm but was undetectable in infertile sperm, whereas that of CB1 and CB2 receptors was not statistically different in the two groups. In conclusion, this study identified unprecedented alterations of the ECS in infertile sperm, that might impact on capacitation and acrosome reaction, and hence fertilization outcomes. These alterations might also point to new biomarkers to determine male reproductive defects, and identify distinct ECS elements as novel targets for therapeutic exploitation of ECS-oriented drugs to treat male fertility problems.
