Meta-Analysis
AIMS
Due to its high heterogenicity and unclear etiology, there is currently no specific treatment for polycystic ovary syndrome (PCOS). Metformin, as an insulin sensitizer, combined with spironolactone, an antiandrogen medication, may exert complementary effects on PCOS. We therefore performed a meta-analysis of trials in which metformin combined with spironolactone was applied to treat PCOS to evaluate the efficacy and safety of the combination therapy.
METHODS
We retrieved the PubMed, Embase, Scopus, Cochrane Library, CNKI, CBM, Wangfang, and VIP databases for literatures published from their inception to December 16, 2022 on the effects of metformin combined with spironolactone in the treatment of PCOS. Inclusion criteria according to P.I.C.O.S criteria were: PCOS patients, metformin combined with spironolactone interventions, metformin alone control group, and randomized controlled trials with the following outcome data: body mass index (BMI), hirsutism score, luteinizing hormone (LH), follicle-stimulating hormone (FSH), total testosterone (TT), fasting blood glucose (FBG), Homeostatic Model Assessment for Insulin Resistance (HOMA-IR), and side effects including nausea, vomiting, diarrhea and drug withdrawal.
RESULTS
Our results revealed that metformin combined with spironolactone significantly reduced BMI and TT, but that it exerted no significant effects on hirsutism score, or on FSH or LH concentrations. Combined treatment also resulted in a significant diminution in FBG and insulin resistance using the HOMA-IR when the interventional time was greater than 6 months. In addition, the combination did not have a higher occurrence of adverse reactions than metformin alone.
CONCLUSION
Compared with metformin alone, metformin combined with spironolactone therapy may be more effective in reducing BMI and serum androgen levels, but the combination showed no significant effect on the hirsutism score or gonadotropin hormone levels, and was not associated with an elevation in side-effects. Moreover, when the treatment course was greater than 6 months, combination therapy reduced FBG and improved insulin resistance more effectively than metformin alone. However, more research is needed to determine the most effective course of treatment.

Meta-Analysis
OBJECTIVE
Hypogonadotropic hypogonadism is characterized by inadequate secretion of pituitary gonadotropins, leading to absent, partial, or arrested puberty. In males, classical treatment with testosterone promotes virilization but not testicular growth or spermatogenesis. To quantify treatment practices and efficacy, we systematically reviewed all studies investigating gonadotropins for the achievement of pubertal outcomes in males with hypogonadotropic hypogonadism.
DESIGN
Systematic review and meta-analysis.
METHODS
A systematic review of Medline, Embase, Global Health, and PsycINFO databases in December 2022. Risk of Bias 2.0/Risk Of Bias In Non-randomized Studies of Interventions/National Heart, Lung, and Blood Institute tools for quality appraisal. Protocol registered on PROSPERO (CRD42022381713).
RESULTS
After screening 3925 abstracts, 103 studies were identified including 5328 patients from 21 countries. The average age of participants was <25 years in 45.6% (n = 47) of studies. Studies utilized human chorionic gonadotropin (hCG) (n = 93, 90.3% of studies), human menopausal gonadotropin (n = 42, 40.8%), follicle-stimulating hormone (FSH) (n = 37, 35.9%), and gonadotropin-releasing hormone (28.2% n = 29). The median reported duration of treatment/follow-up was 18 months (interquartile range 10.5-24 months). Gonadotropins induced significant increases in testicular volume, penile size, and testosterone in over 98% of analyses. Spermatogenesis rates were higher with hCG + FSH (86%, 95% confidence interval [CI] 82%-91%) as compared with hCG alone (40%, 95% CI 25%-56%). However, study heterogeneity and treatment variability were high.
CONCLUSIONS
This systematic review provides convincing evidence of the efficacy of gonadotropins for pubertal induction. However, there remains substantial heterogeneity in treatment choice, dose, duration, and outcomes assessed. Formal guidelines and randomized studies are needed.

Review
Despite recent advancements, treatment of cytopenia due to bone marrow failures (BMF) and myeloid neoplasms remains challenging. Androgens promote renewal and maturation of blood cells and may be beneficial in these forms. Here we report a systematic review of androgens use as single agent in hematologic conditions. Forty-six studies, mainly retrospective with various androgen types and doses, were included: 12 on acquired aplastic anemia (AA), 11 on inherited BMF, 17 on myelodysplastic syndromes (MDS), and 7 on myelofibrosis. Responses ranged from 50 to 70% in inherited BMF, 40-50% in acquired AA and MDS, while very limited evidence emerged for myelofibrosis. In acquired AA, response was associated with presence of non-severe disease; in MDS androgens were more effective on thrombocytopenia or mild to moderate anemia, whilst limited benefit was observed for transfusion dependent anemia. Toxicity profile mainly consisted of virilization and liver enzyme elevation, whilst the risk of leukemic evolution remains controversial.

Psycho-oncology Nov 2023To evaluate the evidence base for patient, oncological, and treatment prognostic factors associated with multiple mental wellbeing outcomes in prostate cancer patients. (Meta-Analysis)
Meta-Analysis Review
OBJECTIVES
To evaluate the evidence base for patient, oncological, and treatment prognostic factors associated with multiple mental wellbeing outcomes in prostate cancer patients.
METHODS
We performed a literature search of MEDLINE, EMBASE, and CINAHL databases including studies evaluating patient, oncological, or treatment factors against one of five mental wellbeing outcomes; depression, anxiety, fear of cancer recurrence, masculinity, and body image perception. Data synthesis included a random effects meta-analysis for the prognostic effect of individual factors if sufficient homogenous data was available, with a structured narrative synthesis where this was not possible.
RESULTS
A final 62 articles were included. Older age was associated with a reducing odds of depression (OR 0.97, p = 0.04), with little evidence of effect for other outcomes. Additionally, baseline mental health status was related to depression and increasing time since diagnosis was associated with reducing fear of recurrence, albeith with low certainty of evidence. However, few other patient or oncological factors demonstrated any coherent relationship with any wellbeing outcome. Androgen deprivation therapy was associated with increased depression (HR 1.65, 95% CI 1.41-1.92, p < 0.01) and anxiety, however, little difference was seen between other treatment options. Overall, whilst numerous factors were identified, most were evaluated by single studies with few evaluating masculinity and body image outcomes.
CONCLUSION
We highlight the existing evidence for prognostic factors in mental wellbeing outcomes in prostate cancer, allowing us to consider high-risk groups of patients for preventative and treatment measures. However, the current evidence is heterogenous with further work required exploring less conclusive factors and outcomes.

Frontiers in Endocrinology 2024To evaluate the effects of behavioral intervention for polycystic ovary syndrome (PCOS). (Meta-Analysis)
Meta-Analysis
The effects of behavioral intervention on anthropometric, clinical, and biochemical parameters in patients with polycystic ovary syndrome: a systematic review and meta-analysis.
OBJECTIVE
To evaluate the effects of behavioral intervention for polycystic ovary syndrome (PCOS).
METHODS
Electronic databases were searched, including Pubmed, Medline, EMBASE, and the Cochrane Central Register of Controlled Trials from inception to 1 April 2023. Inclusion criteria for this study required a diagnosis of PCOS. Interventions of interest included behavioral intervention and routine treatment compared with routine treatment. The studies included in the analysis were designed as randomized controlled trials (RCTs). We conducted meta-analyses following the recommended guidelines. The data was analyzed using either the random effects model or fixed effects model. The results of the studies were expressed as either mean differences (MD) or standardized mean differences (SMD) along with their corresponding 95% confidence intervals (CIs).
RESULTS
Eight RCTs were identified, including data from 744 patients (415 in the intervention group and 329 in the control group). The results indicate an improvement in the effectiveness of behavioral interventions for weight loss (MD: -1.07; 95% CI: -2.1 to 0.03; I = 0%; P=0.04), body mass index (BMI) (MD: -1.12; 95% CI: -1.92 to -0.33; I = 73%; P=0.006), waist circumference (MD: -3.97; 95% CI: -5.64 to -2.29; I = 0%; P<0.00001), quality of life about weight (MD: 0.58; 95% CI: 0.15 to 1.02; I = 0%; P=0.008), depression (SMD: -1.12; 95% CI: -2.35 to -0.07; I = 92%; P=0.04), and triglycerides (MD: -0.16; 95% CI: -0.27 to -0.05; I = 27%; P=0.004). However, there were no significant differences in menstrual cycles, hirsutism, emotions, and infertility. The study also found that behavioral interventions had no significant effect on systolic and diastolic blood pressure, high-density lipoprotein, low-density lipoprotein, homeostasis model assessment of insulin resistance, testosterone, total cholesterol, fasting glucose, fasting insulin, hemoglobin A1C, and sex hormone binding globulin.
CONCLUSION
Behavioral intervention supplementation contributes to weight loss, reduction in BMI and waist circumference, and improvement in depression among patients with PCOS. However, no significant improvement was observed in the biochemical index and quality of life. The long-term effects of behavioral intervention for PCOS remain unclear due to limitations in the quality of the studies involved and the short duration of treatment.

Gender-transformative health interventions that involve men and boys are gaining global reach, adaptability to specific geographical, population and epidemiological contexts, public endorsement, and conceptual sophistication. However, the ways in which masculinities are conceptualised and operationalised in theory and practice across these interventions remains unclear. The purpose of this scoping review is to map intervention studies that conceptually grapple with masculinities and analyse: a) how the concept of masculinities is adapted and operationalised in gender-transformative interventions, with respect to intervention population and context, b) what the relationship between the concept of masculinities and its wider theoretical embedding is, and c) on which levels transformation can be observed when working with 'masculinities'.We conducted a search in APA Psych Articles, APA PsycINFO, and CINAHL via EBSCO, MedLine, PubMed, and Web of Sciences (December 2021) looking for peer-reviewed studies on gender-transformative health interventions which engaged with masculinities conceptually. There were no restrictions regarding language, publication date, or geography. Forty-two articles were included in this review. Our abductive analysis finds that 'hegemonic masculinities' is a central concept in almost all included studies. This shows how the concept is adaptable to a range of different intervention contexts. The review further identifies five theoretical approaches, that help operationalise masculinities on an analytical level: feminist framework, affect theory, critical pedagogy, theories of social change, and ecological approaches. Lastly, this review draws out six levels on which transformation can be observed in the intervention outcomes: relational level, symbolic level, material level, affective level, cognitive-behavioural level, and community-structural level. The discussion underlines that processes and practices of (gender) transformation also require engagement with theories of transformation more widely and advocates for theoretical pluralism. Lastly, implications for practice, including preventative, ecological and community-based care models, are drawn out.

Review
Sexual disorders such as erectile dysfunction (ED), sterility, and sexual inappetence represent some of the complex reproductive challenges that require addressing the underlying causes. The aim of this paper was to systematically synthesize literature on the ethnobotany, phytochemistry, bioactivities, and safety of plants used as remedies for managing sexual dysfunction and infertility, and improving fertility and virility in the EAC. Through an extensive review conducted in multidisciplinary electronic databases, 171 plant species were identified to have been reported for the management of sexual inappetence (i.e., used as aphrodisiacs, 39.4%), ED (35.9%), infertility (18.7%), and increasing fertility (6.0%). The most used plants are , , , , , , and while roots (44.9%), leaves (21.8%), stem and root barks (16.7%) of shrubs (35%), trees (31%), herbs (26%), and climbers (8%) are the preferred organs for making decoctions (69%). The research strides to date indicate that , , , , , , and have been assessed for their bioactivity. The majority (71.4%) of the plants either increased testosterone levels and mounting frequency or elicited prosexual stimulatory effects in male rats. More studies investigating the relevant pharmacological activities (aphrodisiac, fertility, and phosphodiesterase-5 inhibitory activities), safety aspects, responsible compounds, and clinical studies are warranted to establish the pharmacological potential of the unstudied species and elucidate the mechanism of action of the bioactive compounds.

INTRODUCTION
This systematic review examines the impacts of suicide bereavement on men's psychosocial outcomes relating to suicidality, mental health, substance use, grief, and social functioning. Given the high global incidence of suicide and the substantial number of individuals affected by each suicide, understanding the specific experiences and outcomes for men is crucial, particularly in the context of observed gender differences in suicide rates, grief coping styles and mental health outcomes.
METHODS
Adhering to PRISMA guidelines, this review included peer-reviewed, English-language studies that involved men bereaved by suicide using quantitative, qualitative and mixed-methods designs. Searches were conducted in MEDLINE, Embase, Emcare, PsycINFO, and Scopus. Analysis used narrative synthesis methods due to the heterogeneity of findings. These were categorised based on comparison groups: non-bereaved men, or women bereaved by suicide. Prospero registration: CRD42023437034.
RESULTS
The review included 35 studies (25 quantitative, 8 qualitative, 2 mixed-methods) published between 1995 and 2023. Compared to non-bereaved men, suicide-bereaved men are more likely to experience adverse psychosocial outcomes included increased suicide mortality, heightened susceptibility to mental health problems such as depression and posttraumatic stress disorder, and challenges in interpersonal relationships and social functioning. The review also identified gender differences in grief responses and coping strategies, with men often exhibiting more pronounced grief reactions and facing unique challenges due to societal expectations and norms regarding masculinity.
DISCUSSION
The findings of this review underscore the elevated risk of adverse suicide- and mental-health related outcomes for suicide-bereaved men and the need for tailored postvention supports for this cohort. Gender-specific factors, including cultural norms and coping strategies, significantly influence men's experiences of suicide bereavement. Further qualitative and longitudinal quantitative exploration is needed to enhance understanding and effective support for men bereaved by suicide.

Sexual and dating violence (SDV) by male youth (≤ 25 years)-including sexual harassment, emotional partner violence, and rape-is a worldwide problem. The goal of this preregistered (PROSPERO, ID: CRD42022281220) systematic review was to map existing SDV prevention programs aimed at male youth, including their characteristics (e.g., content, intensity), intended psychosexual outcomes, and empirically demonstrated effectiveness, guided by the principles of the theory of planned behavior (TPB). We conducted searches in six online databases for published, peer-reviewed quantitative effectiveness studies on multi-session, group focused, and interaction based SDV prevention programs for male youth ending March 2022. After screening of 21,156 hits using PRISMA guidelines, 15 studies on 13 different programs, from four continents were included. Narrative analysis showed, first, broad ranges in program intensity (2-48 h total), and few program curricula included explicit discussion of relevant aspects of the TPB. Second, programs' main intended psychosexual outcomes were to change SDV experiences, or related attitudes, or norms. Third, significant effects were found mostly on longer term behaviors and short-term attitudes. Other theoretical proxies of SDV experiences, such as social norms and perceived behavioral control, were sparsely investigated; thus, program effectiveness on these outcomes remains largely unknown. Assessed with the Cochrane Risk of Bias Tool, moderate to serious risk of bias arose in all studies. We present concrete suggestions for program content, such as explicit attention to victimization and masculinity and discuss best practices for evaluation research, including assessments of program integrity, and examining relevant theoretical proxies of SDV.

Review
The increase in practices related to enhancing penile size can be attributed to the belief that an improved genital appearance contributes to a man's virility, coupled with an altered self-perception of his body. It is crucial to tailor interventions to meet the genuine needs of patients by thoroughly assessing their history, psychological state, and potential surgical benefits, all while considering the associated risks of complications. This systematic review aims to summarize the available evidence on outcomes, complications, and quality of life after penile augmentation surgery, examining both minimally invasive and more radical techniques. A search of the PubMed and Scopus databases, focusing on English-language papers published in the last 15 years, was performed in December 2023. Papers discussing surgery in animal models and case reports were excluded from the present study unless further evaluated in a follow-up case series. The primary outcomes were changes in penile dimensions, specifically in terms of length and girth, as well as the incidence of surgical complications and the impact on quality of life. A total of 1670 articles were retrieved from the search and 46 were included for analysis. Procedures for penile length perceived enhancements include lipoplasty, skin reconstruction plasty, V-Y and Z plasty, flap reconstruction, scrotoplasty, ventral phalloplasty, and suspensory ligament release; techniques for increasing corporal penile length include penile disassembly, total phalloplasty, and sliding elongation. Finally, penile girth enhancement may be performed using soft tissue fillers, grafting procedures, biodegradable scaffolds, and Penuma. In conclusion, while penile augmentation surgeries offer potential solutions for individuals concerned about genital size, the risks and complexities need to be accounted for.
