The search terms included the following: “Klotho” AND “Sperm” OR “Testicle” OR “Oocyte” OR “Ovary” OR “Reproduction” OR “Fertility” OR “Infertility” OR “Gamete” OR “Gonad.” Following Cochrane methodology, the search covered MEDLINE, EMBASE, Cochrane Library, National Center for Biotechnology Information Gene, Tabula Sapiens, GTEx, Trip Database, Google Scholar, medRxiv, Open Grey, Central Register of Controlled Trials, and World Health Organization International Clinical Trials Registry, including all relevant studies up to March 2024 without language or publication status restrictions. The focus was on the role of alpha-Klotho in fertility, including studies involving animals and humans and basic experimental or observational designs. After removing duplicates, 2 investigators (N.S-.G., F.M.) independently screened titles and abstracts, with disagreements resolved by a third investigator (P.S.). The search identified a total of 258 articles, of which 18 were selected for the review. Final eligibility was determined by 4 investigators (N.S-.G., P.S., T.Q-.L., F.M.).</div></div><div><h3>Results</h3><div>The Klotho protein levels decrease with age. This decline influences male fertility by impacting spermatogenesis, sperm maturation, androgen production, and local homeostasis. In women, KL influences ovulatory function by inhibiting hypothalamic gonadotropin-releasing hormone secretion, regulating growth hormone secretion and oocyte quality, and controlling granulosa cells and follicular apoptosis. Overall, animal and human studies indicate that Klotho is an important factor in fertility, contributing to sperm quality and oocyte maturation and development. Additionally, the antioxidant properties of KL may help preserve the integrity of sperm cells and could serve as an effective antioxidant for the cryopreservation of ovarian tissue.</div></div><div><h3>Conclusion</h3><div>Further research is warranted to fully understand the mechanisms underlying the role of KL protein in human fertility, both as a potential biomarker and as a therapeutic target for infertility treatments and fertility preservation strategies. Advances in functional genetic variations studies will clarify the pathways linking genotype to phenotype in reproductive health.</div></div>","PeriodicalId":73011,"journal":{"name":"F&S reviews","volume":"6 1","pages":"Article 100084"},"PeriodicalIF":0.0,"publicationDate":"2024-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143134271","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, we conducted a systematic review and meta-analysis to investigate the overall prevalence of symptomatic individuals with ultrasound/magnetic resonance imaging–diagnosed adenomyosis in the 12–25 year-age group. This could inform management and treatment decisions.&lt;/div&gt;&lt;/div&gt;&lt;div&gt;&lt;h3&gt;Evidence Review&lt;/h3&gt;&lt;div&gt;The PubMed/Medline, Embase, and Scopus databases were searched for full-length, English-language reports published between 2015 and 2024. This systematic review with meta-analysis was conducted and reported following the Joanna Briggs Institute methodological guidance for systematic reviews of observational epidemiological studies reporting prevalence and cumulative incidence data. We included observational studies that assessed the number of patients with adenomyosis among adolescents and young women, the majority of whom presented with dysmenorrhea. The methodological quality of the included studies and their potential risk of bias were ascertained using the Joanna Briggs Institute Critical Appraisal Tool for Prevalence Studies. The main outcome was the prevalence of adenomyosis among symptomatic adolescents (midpoint of the study age range, &lt;20 years) and young women (midpoint of the study age range, ≥20 years). Three meta-analyses, categorized by age, were performed using Stata to pool adenomyosis prevalence data from selected studies. The risk of endometriosis in women with and without adenomyosis was ultimately assessed as an exploratory and confirmatory investigation by combining the odds ratio estimates from each study using the random-effects model.&lt;/div&gt;&lt;/div&gt;&lt;div&gt;&lt;h3&gt;Results&lt;/h3&gt;&lt;div&gt;Six studies comprising 1,300 individuals met the inclusion criteria. The prevalence of adenomyosis ranged from 5.9% to 46.0%, with an overall weighted mean of 20.7% (95% confidence interval [CI], 11.5–31.6) with high heterogeneity (&lt;em&gt;I&lt;/em&gt;&lt;sup&gt;&lt;em&gt;2&lt;/em&gt;&lt;/sup&gt; = 94.8%). The aggregate estimates were as 16.9% (95% CI, 8.8%–27.0%) in the adolescent subgroup and 29.7% (95% CI, 17.5%–43.5%) in the young woman subgroup. The risk of endometriosis in patients with adenomyosis was significantly higher than that in patients without adenomyosis, with a pooled odds ratio of 3.39 (95% CI, 2.11–5.45), without statistically significant heterogeneity across studies.&lt;/div&gt;&lt;/div&gt;&lt;div&gt;&lt;h3&gt;Conclusion&lt;/h3&gt;&lt;div&gt;The findings of the present review should assist clinicians in developing a high index of suspicion for adenomyosis when adolescents and young women present with chronic severe dysmenorrhea and menorrhagia.

Here, we review the scientific evidence showing how the menstrual cycle meets these criteria and should, therefore, be treated as a vital sign. Using key words and controlled vocabulary terms, we performed multiple literature searches, prioritizing the inclusion of systematic reviews, meta-analyses, and clinical practice guidelines. This review describes how the menstrual cycle is a health indicator, how it cyclically can impact health conditions, and its associations with long-term postmenopausal health outcomes. We review exposures influencing the menstrual cycle, evidence underlying its use to optimize wellness, and available tools for documenting cycles. Supplemental materials include patient handouts on menstrual cycle tracking and an index of related clinical practice guidelines and reviews by subject. The menstrual cycle is a vital sign from menarche through menopause, an underused but powerful tool for understanding gynecological and general health.</div></div>","PeriodicalId":73011,"journal":{"name":"F&S reviews","volume":"6 1","pages":"Article 100081"},"PeriodicalIF":0.0,"publicationDate":"2024-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143134272","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Of the numerous potential causes of male infertility, varicocele is the most common and correctable. Although there are several hypotheses for the mechanism by which varicocele may cause symptoms such as infertility, pain, or hypogonadism, many patients with varicocele remain asymptomatic, and it remains unclear why only a subset of men with varicocele develop symptomatic pathology. Biomarkers are measurable indicators of disease presence or progression and have been proposed for use in the diagnosis and management of men with various reproductive conditions, including varicocele. This study examines a range of markers, including proteins, ribonucleic acid, deoxyribonucleic acid, and metabolites. Proteins implicated in heat shock reactions, oxidative stress, and mitochondrial function, including heat shock protein family A member 2, apolipoprotein A2, and TOM22, have been investigated within the context of varicocele when compared with their expression in healthy men. Additionally, potential biomarkers associated with sperm motility and spermatogenesis, such as serpin family A member 5 and adenosine triphosphate synthase delta domain protein, have been identified with studies showing improvement in concentrations post varicocelectomy. The pursuit of noninvasive biomarkers has gained significance for predicting improvement in fertility and assessing responses to varicocelectomy, offering opportunities for early intervention, minimizing unnecessary surgeries, and optimizing patient outcomes.
