Asexuality is a lack of sexual attraction to any gender. There is some evidence to suggest that many self-identified asexuals have a formal diagnosis of autism spectrum disorder which is characterized by deficits in social interaction and communication, as well as by restricted and repetitive interests and behaviors. Additionally, the literature shows that asexuality and lack of sexual attraction or low sexual interest is overrepresented in people with autism spectrum disorder compared with neurotypical samples. Nevertheless, no studies have been conducted to investigate the relationship between autism and asexuality in depth. We conducted a systematic review of the literature to examine whether asexuality and autism spectrum disorder are connected. We conclude that asexuality and autism share various aspects, such as a possible role of prenatal factors, reference to romantic dimensions of sexual attraction and sexual orientation, and non-partner-oriented sexual desire, but future research should explore and clarify this link.

Review
In the time of transition to parenthood, many physical, psychological and social changes may affect the multidimensional theme of sexuality. This area plays a significant role in the overall well-being of the individual, the couple and the family. The aim of this systematic review is to consider current and emerging trends in the study of sexual function during pregnancy and after childbirth, evaluating the available evidence in the literature reported in specific reviews, and pulling together the suggestions that various authors have brought forward as being useful for daily clinical practice. A total of 4 databases were searched on EBSCOhost: MEDLINE, Cochrane reviews, CINAHAL, and PsychInfo. A systematic search strategy was formulated using the key terms Sexuality, Sexual, Pregnancy, Postpartum, Puerperium, Perinatal, and Review. Eleven articles were included. The results revealed a gradual decline in the frequency of sexual behaviour throughout pregnancy, sharper in the third trimester. Sexual activity started to be resumed around 6-8 weeks after childbirth, to fully recover only after 6 months. A simultaneous change in sexual function was also found, such as less orgasm, sexual desire and satisfaction, more dyspareunia. Many aspects are related to these changes: physical, psychological and social factors, fears about negative consequences of sexual intercourse, inadequate or absent professional counselling about sexuality, method of delivery and breastfeeding. Healthcare professionals need to adequately inform couples about the common fluctuations in sexual activity, interest, desire, and responsiveness over the course of the pregnancy and following childbirth. Joint counselling, if possible, is preferred.

PURPOSE
With cannabis consumption on the rise and use prominent among males of reproductive age it is essential to understand the potential impact of cannabis on male fertility. We reviewed the literature regarding the effects of cannabis on male fertility.
MATERIALS AND METHODS
We performed a literature search using PubMed®/MEDLINE® to identify relevant studies of the effects of cannabis on male fertility. Relevant studies were identified and reviewed.
RESULTS
The strongest evidence of cannabis induced alterations in male fertility is in the category of semen parameters. Research supports a role for cannabis in reducing sperm count and concentration, inducing abnormalities in sperm morphology, reducing sperm motility and viability, and inhibiting capacitation and fertilizing capacity. Animal models demonstrate a role for cannabis in testicular atrophy, and reduced libido and sexual function but to our knowledge these results have not yet been replicated in human studies. Studies of hormonal changes suggest inconclusive effects on testosterone levels, lowered luteinizing hormone levels and unchanged follicle-stimulating hormone levels.
CONCLUSIONS
Current research suggests that cannabis may negatively impact male fertility. Further studies are needed to validate that robust findings in animal models will carry over into human experience. Clinicians should be aware of these potential effects when prescribing medical marijuana therapies to men of reproductive age, and they should consider the degree of cannabis use as a possible component of a complete male infertility workup.

Meta-Analysis
BACKGROUND
The benefits and risks of testosterone treatment for women with diminished sexual wellbeing remain controversial. We did a systematic review and meta-analysis to assess potential benefits and risks of testosterone for women.
METHODS
We searched MEDLINE, Embase, the Cochrane Central Register of Controlled Trials, and Web of Science for blinded, randomised controlled trials of testosterone treatment of at least 12 weeks' duration completed between Jan 1, 1990, and Dec 10, 2018. We also searched drug registration applications to the European Medicine Agency and the US Food and Drug Administration to identify any unpublished data. Primary outcomes were the effects of testosterone on sexual function, cardiometabolic variables, cognitive measures, and musculoskeletal health. This study is registered with the International Prospective Register of Systematic Reviews (PROSPERO), number CRD42018104073.
FINDINGS
Our search strategy retrieved 46 reports of 36 randomised controlled trials comprising 8480 participants. Our meta-analysis showed that, compared with placebo or a comparator (eg, oestrogen, with or without progestogen), testosterone significantly increased sexual function, including satisfactory sexual event frequency (mean difference 0·85, 95% CI 0·52 to 1·18), sexual desire (standardised mean difference 0·36, 95% CI 0·22 to 0·50), pleasure (mean difference 6·86, 95% CI 5·19 to 8·52), arousal (standardised mean difference 0·28, 95% CI 0·21 to 0·35), orgasm (standardised mean difference 0·25, 95% CI 0·18 to 0·32), responsiveness (standardised mean difference 0·28, 95% CI 0·21 to 0·35), and self-image (mean difference 5·64, 95% CI 4·03 to 7·26), and reduced sexual concerns (mean difference 8·99, 95% CI 6·90 to 11·08) and distress (standardised mean difference -0·27, 95% CI -0·36 to -0·17) in postmenopausal women. A significant rise in the amount of LDL-cholesterol, and reductions in the amounts of total cholesterol, HDL-cholesterol, and triglycerides, were seen with testosterone administered orally, but not when administered non-orally (eg, by transdermal patch or cream). An overall increase in weight was recorded with testosterone treatment. No effects of testosterone were reported for body composition, musculoskeletal variables, or cognitive measures, although the number of women who contributed data for these outcomes was small. Testosterone was associated with a significantly greater likelihood of reporting acne and hair growth, but no serious adverse events were recorded.
INTERPRETATION
Testosterone is effective for postmenopausal women with low sexual desire causing distress, with administration via non-oral routes (eg, transdermal application) preferred because of a neutral lipid profile. The effects of testosterone on individual wellbeing and musculoskeletal and cognitive health, as well as long-term safety, warrant further investigation.

Meta-Analysis
IMPORTANCE
In individuals with schizophrenia, antipsychotic-induced dysfunctions are frequent but often underexplored in clinical practice.
OBJECTIVE
To synthetize the data of observational studies exploring the prevalence of sexual dysfunction in individuals with schizophrenia-spectrum disorders as well as associated factors.
DATA SOURCES
A systematic literature search without language or time restrictions was conducted in Google, Google Scholar, PubMed/MEDLINE, Science Direct, and Université Sorbonne Paris Cité for studies published up to June 8, 2022.
STUDY SELECTION
All observational studies reporting a prevalence of sexual dysfunction in schizophrenia-spectrum disorder were included.
DATA EXTRACTION AND SYNTHESIS
The MOOSE guidelines with independent extraction by 2 observers and random-effects models were used.
MAIN OUTCOMES AND MEASURES
The prevalence of sexual dysfunction and each specific dysfunction.
RESULTS
A total of 72 of 1119 studies from 33 countries on 6 continents published from inception to June 2022 were included with a total of 21 076 participants with schizophrenia. The pooled global prevalence of sexual dysfunctions was 56.4% (95% CI, 50.5-62.2), with a prevalence of 55.7% (95% CI, 48.1-63.1) for men and 60.0% (95% CI, 48.0-70.8) for women. The most frequent sexual dysfunction was erectile dysfunction in men (44%; 95% CI, 33.5-55.2), followed by loss of libido in men (41%; 95% CI, 30.7-51.4), ejaculation dysfunction in men (39%; 95% CI, 26.8-51.8), orgasm dysfunction in women (28%; 95% CI, 18.4-40.2), and amenorrhea in women (25%; 95% CI, 17.3-35.0). Factors associated with heterogeneity were study design, time and location, sociodemographic data, alcohol use disorder, psychiatric diagnosis, illness severity, and the use of antidepressants and anxiolytics. Sexual dysfunctions were more frequent in schizophrenia vs schizoaffective disorders, and erectile disorders were less frequent in individuals with longer illness duration. Antidepressant and mood stabilizer prescriptions were associated with lower rates of erection disorders (β, -6.30; 95% CI, -10.82 to -1.78); P = .006 and -13.21; 95% CI, -17.59 to -8.83; P < .001, respectively) and ejaculation disorders (β, -6.10; 95% CI, -10.68 to -1.53; P = .009 and β, -11.57; 95% CI, -16.34 to -6.80; P < .001, respectively). No obvious improvements in the rates of sexual dysfunction at other times were found, and there were conflicting results regarding antipsychotic classes.
CONCLUSIONS AND RELEVANCE
This systematic review and meta-analysis found a high prevalence of sexual dysfunction among individuals with schizophrenia, with considerable heterogeneity in associated factors. The findings also suggest that some dysfunctions may be explained by schizophrenia. The association between lower rates of dysfunction and antidepressant use suggests that treating comorbid depression could be an effective strategy to improve sexual health. A lack of data on metabolic parameters and physical health in general was also noted, while these issues are frequent in the care of schizophrenia.

Finasteride and minoxidil are medicaments commonly prescribed for treating benign prostatic hyperplasia (BPA), hypertension, and/or androgenetic alopecia (AGA). The mechanism of action of finasteride is based on the interference in androgenic pathways, which may lead to fertility-related disorders in men. Minoxidil, however, can act in multiple ways, and there is no consensus that its use can adversely affect male fertility. Since finasteride and minoxidil could be risk factors for male fertility, we aimed to compare their impact on the two reproductive organs testis and epididymis of adult murine models, besides testis/epididymis-related cells, and describe the mechanism of action involved. For such, we used the PRISMA guideline. We included 31 original studies from a structured search on PubMed/MEDLINE, Scopus, and Web of Science databases. For in vivo studies, the bias analysis and the quality of the studies were assessed as described by SYRCLE (Systematic Review Centre for Laboratory Animal Experimentation). We concluded that finasteride and minoxidil act as hormone disruptors, causing oxidative stress and morphological changes mainly in the testis. Our results also revealed that finasteride treatment could be more harmful to male reproductive health because it was more associated with reproductive injuries, including damage to the epididymis, erectile dysfunction, decreased libido, and reduced semen volume. Thus, this study contributes to the global understanding of the mechanisms by which medicaments used for alopecia might lead to male reproductive disorders. We hope that our critical analysis expedites clinical research and reduces methodological bias. The registration number on the Prospero platform is CRD42022313347.

BACKGROUND
Anabolic-androgenic steroids (AASs) are often used by men for bodybuilding and to improve sports performance. The use is not limited to professional competitive athletes, but many amateur men.
OBJECTIVE
The objective of this study was to assess and systematically review the effects of AAS on male fertility parameters, spermiogram, testosterone, follicle-stimulating hormone (FSH) and luteinising hormone (LH) and to review reversibility and other morbidity impacting fertility.
METHODS
Eligibility criteria - We included studies mentioning data about adult males using supraphysiologic doses of AAS for sports performance or appearance enhancement, with comparison data from general population or matched controls if available reporting fertility parameters and sexual performance. Information sources - A systematic literature search was performed using PubMed, MEDLINE, EMBASE, Google Scholar and World of Science. Controlled clinical trials randomised or nonrandomised (if available), case series with or without matched controls, case reports, cross-sectional surveys, reports on follow-up of subjects caught in doping test and their fertility parameters when reported. Risk of bias/quality assessment - The quality assessment of the included studies was performed using the Newcastle-Ottawa Scale.
RESULTS
Included studies - Thirty-two studies were included. There were 12 cohort studies, 5 case-control studies, 9 cross-sectional surveys and 6 case reports. The study population comprised 9371 individuals, of which 2671 were AAS users. Synthesis of results - AAS users had reduced levels of FSH and LH than the naïve population. These levels remained low for 3-6 months after stopping AAS. One year after stopping AAS, the users and naïve population had insignificant differences in FSH and LH values. The total testosterone (TT) levels were comparable in users and naïve populations at baseline, 3 months and 6 months after stopping, but at 1 year, TT values were lower in AAS users. Sperm concentration in AAS users and naïve population was similar, but sperm motility was lower in AAS users. The testicular size was lower in AAS users. The erectile function improved with AAS use, but on withdrawal, there was decreased libido and erectile dysfunction. Most AAS users need additional medications to mitigate detrimental effects on fertility. Description of the effect - AAS use negatively impacted the gonadotrophin levels and had lower sperm motility and testicular size. Strength - Comprehensive review of 32 publications, study population of 9371 individuals, of which 2671 were AAS users, meta-analysis of reproductive hormones, semen parameters and testis size.
LIMITATIONS
The limitations are small sample size of most of the studies, polypharmacy, lack of information on dosing and high heterogeneity.
INTERPRETATION
AAS use is detrimental for sperm motility and has a partially reversible negative impact on male fertility. Users must be cautioned about its negative impact on libido and erectile function. PROSPERO Registration No. CRD42023411294.

BACKGROUND
Sexual dysfunction is thought to be highly prevalent in patients with psychiatric disorders. Factors such as the use of psychotropic substances (ie, psychopharmaceuticals and drugs), age, or somatic diseases may contribute to sexual problems, but the extent to which psychopathology itself affects sexual functioning is not well understood.
AIM
The study sought to provide an overview of the literature on the prevalence of sexual dysfunction in psychotropic-free and somatic disease-free psychiatric patients.
METHOD
A systematic review (PRISMA [Preferred Reporting Items for Systematic Reviews and Meta-Analyses]) was conducted by 2 authors (TH and AWMP) independently, with the review process being monitored by a third author. Relevant articles on the relationship between sexual dysfunctions and psychopathology were searched in PubMed, Web of Science, and PsycINFO from inception until June 16, 2022. The study methods were entered in the international register of systematic reviews PROSPERO (2021, CRD42021223410).
OUTCOMES
The main outcome measures were sexual dysfunction and sexual satisfaction.
RESULTS
Twenty-four studies were identified, including a total of 1199 patients. These studies focused on depressive disorders (n = 9 studies), anxiety disorders (n = 7), obsessive- compulsive disorder (OCD) (n = 5), schizophrenia (n = 4), and posttraumatic stress disorder (n = 2). No studies on bipolar disorder were found. Reported prevalence rates of sexual dysfunction in psychiatric disorders were 45% to 93% for depressive disorders, 33% to 75% for anxiety disorders, 25% to 81% for OCD, and 25% for schizophrenia. The most affected phase of the sexual response cycle was sexual desire, in both men and women with depressive disorders, posttraumatic stress disorder, and schizophrenia. Patients with OCD and anxiety disorders most frequently reported dysfunction in the orgasm phase, 24% to 44% and 7% to 48%, respectively.
CLINICAL IMPLICATIONS
The high prevalence of sexual dysfunction requires more clinical attention by means of psychoeducation, clinical guidance, sexual anamnesis, and additional sexological treatment.
STRENGTHS AND LIMITATIONS
This is the first systematic review on sexual dysfunction in psychotropic-free and somatic disease-free psychiatric patients. Limitations include the small number of studies, small sample sizes, the use of multiple questionnaires (some not validated), which may contribute to bias.
CONCLUSION
A limited number of studies identified a high prevalence of sexual dysfunction in patients with a psychiatric disorder, with substantial variation between patient groups in frequency and phase of reported sexual dysfunction.

Review
OBJECTIVES
Sexual dysfunction can adversely affect the quality of life and interpersonal relationships. nowadays, a lot of attention is paid to traditional Chinese medicine with better curative effects and less adverse events. Recent studies have implied the promising effect of acupuncture on sexual function. This systematic review evaluate the effectiveness and safety of acupuncture in treating female and male sexual dysfunction.
CONTENT
PubMed, Cochrane Central of Controlled Trials (CENTRAL), EMBASE, Web of Science, China National Knowledge Infrastructure (CNKI), Chinese Biomedical Literature Database (CBM), Scopus, and Google Scholar were searched up to 2021. No limitation to language and date. The methodological quality of the studies was assessed using the Mixed Methods Appraisal Tool (MMAT).
SUMMARY
Among 160 initially assessed papers, 13 articles were included. The findings showed that acupuncture improve sexual dysfunction in domains of desire, libido, erectile dysfunction and impotency. Most studies did not report any serious side effects from acupuncture, and only three studies reported minor adverse events.
OUTLOOK
The available evidence indicate that acupuncture has positive on improvement of sexual dysfunction with no serious side effects. Although acupuncture has gained increasing popularity for the management of sexual dysfunction, high methodological quality evidence regarding its efficacy is lacking.

(Review)
Review
Middle aged women in majority undergoing menopausal symptoms are unaware of the physiological changes happening in their body, necessary lifestyle changes and alternate therapies to overcome the symptoms. All major electronic sources of relevant information were systematically searched and collected data were pooled under specific subheadings. From the reviewed papers, the awareness on symptoms and related complications of menopause in the middle aged women were consolidated. Studies helped to identify alternative therapies replacing or in parallel with the Hormone Replacement Therapy to overcome the menopausal symptoms. Reduced oestrogen and progesterone level causes physiological, psychological, and genitourinary symptoms. Prolonged consequences cause libido, osteoporosis, and cardio vascular diseases. Hypo-estrogenic status is well managed with alternative therapies including dietary intervention, acupuncture, aromatherapy, exercise, and yoga. Dietary interventions involving foods like Fennel, Soy, Black Cohash, St. John Wort, Red Clover and Date Pollen were found to be managing vasomotor symptoms and sexual dysfunction. Non-Hormonal and Non-Pharmacological impact behind acupuncture treatment was well accepted. Various studies proved inhaling and massaging with Lavender, Neroli oil, Fennel, Rose, and Geranium essential oils balance cortisol hormone and reduce stress and anxiety. Impact of yoga therapy on neurohormonal pathways reduce both psychological and physiological symptoms. Reviews summarizes various symptoms and complications during menopausal transition and alternate ways of better management with dietary intervention, yoga, exercise, aromatherapy, and acupuncture to improve the quality of menopausal women's life.
