Interest in the connection between masculinities and mental health continues to grow. However, no previous systematic review has explored this association for adolescents. We present the systematic review of 29 articles that explore the connection between adherence to stereotypical male gender role norms (e.g., emotional restriction), attributes (e.g., "ambitious"), and identity (most commonly, gender "typicality") and internalizing behavior problems and social support. A total of 24,795 adolescent boys (6th-12th grade) were included in the reviewed studies from 1997-2017. In the quantitative articles (n = 20), associations varied by aspect of masculinity assessed. Specifically, we found that greater endorsement of "masculine" traits (e.g., ambitious, assertive) was generally associated with fewer internalizing behavior problems and greater social support. However, lower gender "typicality" and higher adherence to stereotypical gender role norms were generally associated with more internalizing behavior problems and lower social support. In the qualitative articles (n = 9), the most predominant theme was emotional restriction (i.e., a gender role norm) and consequences for mental health. While research in this area is newer for community psychologists, the connection between masculinities and mental health is directly relevant to the field. Given the focus on individual-level conceptions of masculinity and mental health found in our review, we describe key future directions for masculinities research in community psychology.

Androgens play a significant role in the development of male reproductive organs. The clinical use of synthetic testosterone derivatives, such as nandrolone, is focused on maximizing the anabolic effects and minimizing the androgenic ones. Class II anabolic androgenic steroids (AAS), including nandrolone, are rapidly becoming a widespread group of drugs used both clinically and illicitly. The illicit use of AAS is diffused among adolescent and bodybuilders because of their anabolic proprieties and their capacity to increase tolerance to exercise. This systematic review aims to focus on side effects related to illicit AAS abuse, evaluating the scientific literature in order to underline the most frequent side effects on AAS abusers' bodies. A systematic review of the scientific literature was performed using the PubMed database and the keywords "nandrolone decanoate". The inclusion criteria for articles or abstracts were English language and the presence of the following words: "abuse" or "adverse effects". After applying the exclusion and inclusion criteria, from a total of 766 articles, only 148 were considered eligible for the study. The most reported adverse effects (found in more than 5% of the studies) were endocrine effects (18 studies, 42%), such as virilization, gynecomastia, hormonal disorders, dyslipidemia, genital alterations, and infertility; cardiovascular dysfunctions (six studies, 14%) such as vascular damage, coagulation disorders, and arteriosus hypertension; skin disorders (five studies, 12%) such as pricking, acne, and skin spots; psychiatric and mood disorders (four studies, 9%) such as aggressiveness, sleep disorders and anxiety; musculoskeletal disorders (two studies, 5%), excretory disorders (two studies, 5%), and gastrointestinal disorders (two studies, 5%). Based on the result of our study, the most common adverse effects secondary to the abuse of nandrolone decanoate (ND) involve the endocrine, cardiovascular, skin, and psychiatric systems. These data could prove useful to healthcare professionals in both sports and clinical settings.

Meta-Analysis
BACKGROUND
Metformin has been proposed as possibly a safer and more effective long-term treatment than the oral contraceptive pill (OCP) in women with polycystic ovary syndrome (PCOS). It is important to directly compare the efficacy and safety of metformin versus OCP in the long-term treatment of women with PCOS. This is an update of a Cochrane Review comparing insulin sensitising agents with the OCP and only includes studies on metformin.
OBJECTIVES
To assess the effectiveness and safety of metformin versus the OCP (alone or in combination) in improving clinical, hormonal, and metabolic features of PCOS.
SEARCH METHODS
In August 2019 we searched the Cochrane Gynaecology and Fertility Group Trials Register, Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, Embase and CINAHL, the trial registers, handsearched references of the identified articles, and contacted experts in the field to identify additional studies.
SELECTION CRITERIA
We included randomised controlled trials (RCTs) of the use of metformin versus the OCP (alone or in combination) for women with PCOS.
DATA COLLECTION AND ANALYSIS
We used standard methods recommended by Cochrane. The primary review outcomes were the clinical parameters of hirsutism and adverse events, both severe (requiring stopping of medication), and minor. In the presence of substantial heterogeneity (I statistic > 50), which could be explained by pre-specified subgroup analyses on the basis of BMI, we reported the subgroups separately.
MAIN RESULTS
This is a substantive update. We identified 38 additional studies. We included 44 RCTs (2253 women), which comprised 39 RCTs on adult women (2047 women) and five RCTs on adolescent women (206 women). Evidence quality ranged from very low to low. The main limitations were risk of bias, imprecision and inconsistency. Metformin versus the OCP In adult women, we are uncertain of the effect of metformin compared to the OCP on hirsutism in subgroup body mass index (BMI) < 25 kg/m (mean difference (MD) 0.38, 95% confidence interval (CI) -0.44 to 1.19, 3 RCTs, n = 134, I = 50%, very low-quality evidence) and subgroup BMI > 30 kg/m (MD -0.38, 95% CI -1.93 to 1.17; 2 RCTs, n = 85, I = 34%, low-quality evidence). Metformin may be less effective in improving hirsutism compared to the OCP in the subgroup BMI 25 kg/m to 30 kg/m (MD 1.92, 95% CI 1.21 to 2.64, 5 RCTs, n = 254, I = 0%, low-quality evidence). Metformin may increase severe gastro-intestinal adverse events rate compared to the OCP (Peto odds ratio (OR) 6.42, 95% CI 2.98 to 13.84, 11 RCTs, n = 602, I = 0%, low-quality evidence). Metformin may decrease the incidence of severe other adverse events compared to the OCP (Peto OR 0.20, 95% CI 0.09 to 0.44, 8 RCTs, n = 363, I = 0%, low-quality evidence). There were no trials reporting on minor adverse events. In adolescents, we are uncertain whether there is a difference between Metformin and the OCP, on hirsutism and adverse events. Metformin versus metformin combined with the OCP In adult women, metformin may be less effective in improving hirsutism compared to Metformin combined with the OCP (MD 1.36, 95% CI 0.62 to 2.11, 3 RCTs, n = 135, I= 9%, low-quality evidence). We are uncertain if there was a difference between metformin and metformin combined with the OCP for severe gastro-intestinal adverse events (OR 0.74, 95% CI 0.21 to 2.53, 3 RCTs, n = 171, I = 0%, low-quality evidence), or for severe other adverse events (OR 0.56, 95% CI 0.11 to 2.82, 2 RCTs, n = 109, I = 44%, low-quality evidence). There were no trials reporting on minor adverse events. In adolescents, there were no trials for this comparison. The OCP versus metformin combined with the OCP In adult women, the OCP may be less effective in improving hirsutism compared to metformin combined with the OCP (MD 0.54, 95% CI 0.20 to 0.89, 6 RCTs, n = 389, I= 1%, low-quality evidence). The OCP may decrease the incidence of severe gastro-intestinal adverse events compared to metformin combined with the OCP (OR 0.20, 95% CI 0.06 to 0.72, 5 RCTs, n = 228, I = 0%, low-quality evidence). We are uncertain if there is a difference between the OCP and metformin combined with the OCP for severe other adverse events (OR 1.61, 95% CI 0.49 to 5.37, 4 RCTs, n = 159, I = 12%, low-quality evidence). The OCP may decrease the incidence of minor (gastro-intestinal) adverse events compared to metformin combined with the OCP (OR 0.06, 95% CI 0.01 to 0.44, 2 RCTs, n = 98, I = 0%, low-quality evidence). In adolescents, we are uncertain whether there is a difference between the OCP, compared to metformin combined with the OCP, on hirsutism or adverse events.
AUTHORS' CONCLUSIONS
In adult women with PCOS, metformin may be less effective in improving hirsutism compared to the OCP in the subgroup BMI 25 kg/m to 30 kg/m but we are uncertain if there was a difference between metformin and the OCP in subgroups BMI < 25 kg/m and BMI > 30kg/m. Compared to the OCP, metformin may increase the incidence of severe gastro-intestinal adverse events and decrease the incidence of severe other adverse events with no trials reporting on minor adverse events. Either metformin alone or the OCP alone may be less effective in improving hirsutism compared to metformin combined with the OCP. We are uncertain whether there is a difference between the OCP alone and metformin alone compared to metformin combined with the OCP for severe or minor adverse events except for the OCP versus metformin combined with the OCP where the OCP may decrease the incidence of severe and minor gastro-intestinal adverse events. In adolescent women with PCOS, we are uncertain whether there is a difference between any of the comparisons for hirsutism and adverse events due to either no evidence or very low-quality evidence. Further large well-designed RCTs that stratify for BMI are needed to evaluate metformin versus the OCP and combinations in women with PCOS, in particular adolescent women.

Review
PURPOSE
The purpose of this study is to systematically review the current literature on the post-treatment survivorship experiences of African-American men with prostate cancer by exploring qualitative studies to gain a deep understanding of their survivorship experiences.
METHOD
We searched five databases for studies published from 2008 to 2018. We identified ten relevant qualitative studies, conducted a meta-synthesis using Noblit and Hare's meta-ethnography approach, and evaluated their quality appraisal using the validated Critical Appraisal Skills Program.
RESULTS
This review generated a total of four main themes and nine subthemes. The Four main themes included coping strategy, psychophysical impact, health system influence, and socioeconomic impact. Spirituality, healthy behaviors, supportive care of spouse/family/friends and non-communicating/reticent were subthemes identified in the coping strategy theme; physical well-being and sexuality and masculinity were subthemes in the psychophysical impact theme; healthcare provider interaction and treatment decision-making were subthemes identified in the health system influence theme, and health insurance status was the subtheme in the socioeconomic impact theme.
CONCLUSION
Our findings reveal that the experiences of African-American prostate cancer survivors are complex and multidimensional.
IMPLICATIONS FOR CANCER SURVIVORS
This review highlights the need for further studies with African-American prostate cancer survivors, precisely identify their needs and plan a culturally appropriate intervention to meet those needs.

Meta-Analysis
BACKGROUND
The final adult height of untreated girls aged up to 18 years with Turner syndrome (TS) is approximately 20 cm shorter compared with healthy females. Treatment with growth hormone (GH) increases the adult height of people with TS. The effects of adding the androgen, oxandrolone, in addition to GH are unclear. Therefore, we conducted this systematic review to investigate the benefits and harms of oxandrolone as an adjuvant therapy for people with TS treated with GH.
OBJECTIVES
To assess the effects of oxandrolone on growth hormone-treated girls aged up to 18 years with Turner syndrome.
SEARCH METHODS
We searched CENTRAL, MEDLINE, Embase, the ICTRP Search Portal and ClinicalTrials.gov. The date of the last search was October 2018. We applied no language restrictions.
SELECTION CRITERIA
We included randomised controlled clinical trials (RCTs) that enrolled girls aged up to 18 years with TS who were treated with GH and oxandrolone compared with GH only treatment.
DATA COLLECTION AND ANALYSIS
Three review authors independently screened titles and abstracts for relevance, selected trials, extracted data and assessed risk of bias. We resolved disagreements by consensus, or by consultation with a fourth review author. We assessed trials for overall certainty of the evidence using the GRADE instrument.
MAIN RESULTS
We included six trials with 498 participants with TS, 267 participants were randomised to oxandrolone plus GH treatment and 231 participants were randomised to GH only treatment. The individual trial sample size ranged between 22 and 133 participants. The included trials were conducted in 65 different paediatric endocrinology healthcare facilities including clinics, centres, hospitals and academia in the USA and Europe. The duration of interventions ranged between 3 and 7.6 years. The mean age of participants at start of therapy ranged from 9 to 12 years. Overall, we judged only one trial at low risk of bias in all domains and another trial at high risk of bias in most domains. We downgraded the level of evidence mainly because of imprecision (low number of trials, low number of participants or both). Comparing oxandrolone plus GH with GH only for final adult height showed a mean difference (MD) of 2.7 cm in favour of oxandrolone plus GH treatment (95% confidence interval (CI) 1.3 to 4.1; P < 0.001; 5 trials, 270 participants; moderate-quality evidence). The 95% prediction interval ranged between 0.3 cm and 5.1 cm. For adverse events, we based our main analysis on reliable date from two trials with overall low risk of bias. There was no evidence of a difference between oxandrolone plus GH and GH for adverse events (RR 1.81, 95% CI 0.83 to 3.96; P = 0.14; 2 trials, 170 participants; low-quality evidence). Six out of 86 (18.6%) participants receiving oxandrolone plus GH compared with 8/84 (9.5%) participants receiving GH only reported adverse events, mainly signs of virilisation (e.g. deepening of the voice). One trial each investigated the effects of treatments on speech (voice frequency; 88 participants), cognition (51 participants) and psychological status (106 participants). The overall results for these comparisons were inconclusive (very low-quality evidence). No trial reported on health-related quality of life or all-cause mortality.
AUTHORS' CONCLUSIONS
Addition of oxandrolone to the GH therapy led to a modest increase in the final adult height of girls aged up to 18 years with TS. Adverse effects identified included virilising effects such as deepening of the voice, but reporting was inadequate in some trials.

Miscarriage is common, affecting one in five pregnancies, but the psychosocial effects often go unrecognized and unsupported. The effects on men may be subject to unintentional neglect by health care practitioners, who typically focus on biological symptoms, confined to women. Therefore, we set out to systematically review the evidence of lived experiences of male partners in high-income countries. Our search and thematic synthesis of the relevant literature identified 27 manuscripts reporting 22 studies with qualitative methods. The studies collected data from 231 male participants, and revealed the powerful effect of identities assumed and performed by men or constructed for them in the context of miscarriage. We identified perceptions of female precedence, uncertain transition to parenthood, gendered coping responses, and ambiguous relations with health care practitioners. Men were often cast into roles that seemed secondary to others, with limited opportunities to articulate and address any emotions and uncertainties engendered by loss.

OBJECTIVES
To understand help-seeking by male victims of domestic violence and abuse (DVA) and their experiences of support services by systematically identifying qualitative and mixed-method studies and thematically synthesising their findings.
DESIGN
Systematic review and qualitative evidence synthesis. Searches were conducted in 12 databases and the grey literature with no language or date restrictions. Quality appraisal of the studies was carried out using the Critical Appraisal Skills Programme tool. Reviewers extracted first and second order constructs related to help-seeking, identified themes and combined them by interpretative thematic synthesis.
SETTING
DVA experienced by male victims and defined as any incident or pattern of incidents of controlling coercive or threatening behaviour, violence or abuse among people aged 18 or over who are or have been intimate partners or family members, regardless of gender or sexuality.
PARTICIPANTS
Male victims of DVA.
INTERVENTIONS
Any intervention which provides practical and/or psychological support to male victims of DVA including but not limited to DVA-specific services, primary healthcare and sexual health clinics.
PRIMARY AND SECONDARY OUTCOME MEASURES
Qualitative data describing help-seeking experiences and interactions with support services of male victims of domestic violence RESULTS: We included twelve studies which were published between 2006 and 2017. We grouped nine themes described over two phases (a) : fear of disclosure, challenge to masculinity, commitment to relationship, diminished confidence/despondency and invisibility/perception of services; and (b) : initial contact, confidentiality, appropriate professional approaches and inappropriate professional approaches.
CONCLUSION
The recent publication of the primary studies suggests a new interest in the needs of male DVA victims. We have confirmed previously identified barriers to help-seeking by male victims of DVA and provide new insight into barriers and facilitators to service provision.

Compared to women, men are less likely to seek help for mental health difficulties. Despite considerable interest, a paucity in evidence-based solutions remains to solve this problem. The current review sought to synthesize the specific techniques within male-specific interventions that may contribute to an improvement in psychological help-seeking (attitudes, intentions, or behaviors). A systematic review identified 6,598 potential articles from three databases (MEDLINE, EMBASE, and PsycINFO). Nine studies were eligible. A meta-analysis was problematic due to disparate interventions, outcomes, and populations. The decision to use an innovative approach that adopted the Behavior Change Technique (BCT) taxonomy to synthesize each intervention's key features likely to be responsible for improving help-seeking was made. Of the nine studies, four were engagement strategies (i.e., brochures/documentaries), two randomized controlled trials (RCTs), two pilot RCTs, and one retrospective review. Regarding quality assessment, three were scored as "strong," five as "moderate," and one as "weak." Key processes that improved help-seeking attitudes, intentions, or behaviors for men included using role models to convey information, psychoeducational material to improve mental health knowledge, assistance with recognizing and managing symptoms, active problem-solving tasks, motivating behavior change, signposting services, and, finally, content that built on positive male traits (e.g., responsibility and strength). This is the first review to use this novel approach of using BCTs to summarize and identify specific techniques that may contribute to an improvement in male help-seeking interventions, whether engagement with treatment or the intervention itself. Overall, this review summarizes previous male help-seeking interventions, informing future research/clinical developments.

Boys and young men have unique health-related needs that may be poorly met by existing programs and initiatives. The mismatch between the needs of boys and young men and current service offerings-driven largely by social determinants of health such as masculinity-may stymie health status. This is evidenced through high rates of self-stigma, accidental death or suicide, and low rates of help seeking and health literacy among populations of boys and young men. With growing interest in improving wellbeing and educational outcomes for all young people (including boys and young men), this systematic review aimed to evaluate community and school-based programs with specific focus on program features and outcomes directly relevant to young males aged 12-25 years. Five data-bases were searched; Medline, EMBASE, PsycInfo, ERIC, and ERAD. Articles were included if they evaluated an intervention or program with a general or at-risk sample of young men, and measured a psychological, psychosocial, masculinity, or educational outcome. The majority of the 40 included studies had high quality reporting (62.5%). Synthesised data included theoretical frameworks, intervention characteristics, outcomes, and key results. Of the included studies, 14 were male-focussed programs, with masculinity approaches directed towards program aims and content information. The emergent trend indicated that male-targeted interventions may be more beneficial for young men than gender-neutral programs, however, none of these studies incorporated masculine-specific theory as an overarching framework. Furthermore, only three studies measured masculine-specific variables. Studies were limited by a lack of replication and program refinement approaches. It is concluded that there is significant scope for further development of community and school-based health promotion programs that target young men through incorporation of frameworks that consider the impact of gendered social and environmental determinants of health. Evaluation of these programs will provide researchers and practitioners with the capacity for translating beneficial outcomes into best-practice policy.

Meta-Analysis
BACKGROUND
Polycystic ovary syndrome (PCOS) affects 8% to 13% of reproductive-aged women and is associated with reproductive and metabolic dysfunction. Obesity worsens the presentation of PCOS and weight management (weight loss, maintenance or prevention of excess weight gain) is proposed as an initial treatment strategy, best achieved through lifestyle changes incorporating diet, exercise and behavioural interventions.
OBJECTIVES
To assess the effectiveness of lifestyle treatment in improving reproductive, anthropometric (weight and body composition), metabolic and quality of life factors in PCOS.
SEARCH METHODS
We searched the Cochrane Gynaecology and Fertility Specialised Register, the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, Embase, PsycINFO, CINAHL and AMED (date of last search March 2018). We also searched controlled trials registries, conference abstracts, relevant journals, reference lists of relevant papers and reviews, and grey literature databases, with no language restrictions applied.
SELECTION CRITERIA
Randomised controlled trials (RCTs) comparing lifestyle treatment (diet, exercise, behavioural or combined treatments) to minimal or no treatment in women with PCOS.
DATA COLLECTION AND ANALYSIS
Two authors independently selected trials, assessed evidence quality and risk of bias, and extracted data. Our primary outcomes were live birth, miscarriage and pregnancy. We used inverse variance and fixed-effect models in the meta-analyses. We reported dichotomous outcomes as an odds ratio and continuous outcomes as a mean difference (MD) or standardised mean difference (SMD).
MAIN RESULTS
We included 15 studies with 498 participants. Ten studies compared physical activity to minimal dietary and behavioural intervention or no intervention. Five studies compared combined dietary, exercise and behavioural intervention to minimal intervention. One study compared behavioural intervention to minimal intervention. Risk of bias varied: eight studies had adequate sequence generation, seven had adequate clinician or outcome assessor blinding, seven had adequate allocation concealment, six had complete outcome data and six were free of selective reporting. No studies assessed the fertility primary outcomes of live birth or miscarriage. No studies reported the secondary reproductive outcome of menstrual regularity, as defined in this review.Lifestyle intervention may improve a secondary (endocrine) reproductive outcome, the free androgen index (FAI) (MD -1.11, 95% confidence interval (CI) -1.96 to -0.26, 6 RCTs, N = 204, I = 71%, low-quality evidence). Lifestyle intervention may reduce weight (kg) (MD -1.68 kg, 95% CI -2.66 to -0.70, 9 RCTs, N = 353, I = 47%, low-quality evidence). Lifestyle intervention may reduce body mass index (BMI) (kg/m) (-0.34 kg/m, 95% CI -0.68 to -0.01, 12 RCTs, N = 434, I= 0%, low-quality evidence). We are uncertain of the effect of lifestyle intervention on glucose tolerance (glucose outcomes in oral glucose tolerance test) (mmol/L/minute) (SMD -0.02, 95% CI -0.38 to 0.33, 3 RCTs, N = 121, I = 0%, low-quality evidence).
AUTHORS' CONCLUSIONS
Lifestyle intervention may improve the free androgen index (FAI), weight and BMI in women with PCOS. We are uncertain of the effect of lifestyle intervention on glucose tolerance. There were no studies that looked at the effect of lifestyle intervention on live birth, miscarriage or menstrual regularity. Most studies in this review were of low quality mainly due to high or unclear risk of bias across most domains and high heterogeneity for the FAI outcome.
