ABSTRACT
OBJECTIVE: During recent years, evidence-based practice as a way to support higher standards of care was emphasized by health care policymakers. Sexual dysfunction (SD) is a common problem that affects the quality of life in individuals. Today, the use of Ginkgo biloba extract (GBE) for treating SD has been considered, so this study was performed to evaluate the current evidence for the efficacy and safety of ginkgo in treating SD. MATERIALS AND METHODS: In this review study, electronic databases of PubMed, Scopus, Cochrane, Google Scholar, Web of science and Persian databases such as SID and Magiran were searched up to March 2020, to identify all the studies reporting the effect of GBE for effectiveness on sexual function and its safety. The search was performed using the keywords of Ginkgo, Ginkgo biloba, Complementary and alternative medicine, women sexual dysfunction, and male sexual dysfunction. The quality of included studies was assessed using the Oxford Center for Evidence Based Medicine checklist. RESULTS: Among 156 articles found in the initial search, 5 randomized controlled trials (475 participants) were selected for this study. After a meticulous review, we found that G. biloba can have positive effects on the sexual function of postmenopausal women, while evidence shows that it has no effect on the sexual function of antidepressants users. Headaches and gastrointestinal disturbance were among the adverse events mentioned in several trials. CONCLUSION: We concluded that G. biloba has limited positive effects on sexual function and more studies are needed to confirm these findings.
ABSTRACT
OBJECTIVES: The aim of the present systematic review and meta-analysis is the exploration of the potential evidence of the effectiveness of aromatherapy products on the sexual function of menopausal women. METHODS: From inception to December 2017, the search process was performed using the MEDLINE and Scopus databases and the Cochrane Library regarding the trials on the effectiveness of herbal-medicine aromatherapy on the sexual function of menopausal women. RESULTS: Three of the trials comprise suitable data for inclusion in the meta-analysis. According to the meta-analysis, it is possible to improve the standardized mean difference (SMD) of the sexual desire up to 0.56 in the aromatherapy group compared with the control group (SMD = 0.56; P < 0.001; heterogeneity; I2 = 42%; P = 0.141). According to one of the trials, the serum-estrogen level of two different doses did not change in the neroli oil inhalation group compared with the almond-oil group. CONCLUSIONS: Both aromatherapy with neroli oil or lavender (monopreparation) and combined-oil aromatherapy with lavender, fennel, geranium, and rose significantly improved human sexual function; however, a significant change of the serum-estrogen level was not detected. The findings of the present review should be presented cautiously because of the corresponding limitations such as the lack of a standardized tool, the lack of intention-to-treat reporting, the low study amount, and the short-term follow-up.
ABSTRACT
PURPOSE: To evaluate the effect of folate and folate plus zinc supplementation on endocrine parameters and sperm characteristics in sub fertile men. MATERIALS AND METHODS: We conducted a systematic review and meta-analysis. Electronic databases of Medline, Scopus , Google scholar and Persian databases (SID, Iran medex, Magiran, Medlib, Iran doc) were searched from 1966 to December 2016 using a set of relevant keywords including "folate or folic acid AND (infertility, infertile, sterility)".All available randomized controlled trials (RCTs), conducted on a sample of sub fertile men with semen analyses, who took oral folic acid or folate plus zinc, were included. Data collected included endocrine parameters and sperm characteristics. Statistical analyses were done by Comprehensive Meta-analysis Version 2. RESULTS: In total, seven studies were included. Six studies had sufficient data for meta-analysis. "Sperm concentration was statistically higher in men supplemented with folate than with placebo (P < .001)". However, folate supplementation alone did not seem to be more effective than the placebo on the morphology (P = .056) and motility of the sperms (P = .652). Folate plus zinc supplementation did not show any statistically different effect on serum testosterone (P = .86), inhibin B (P = .84), FSH (P = .054), and sperm motility (P = .169) as compared to the placebo. Yet, folate plus zinc showed statistically higher effect on the sperm concentration (P < .001), morphology (P < .001), and serum folate level (P < .001) as compared to placebo. CONCLUSION: Folate plus zinc supplementation has a positive effect on sperm characteristics in sub fertile men. However, these results should be interpreted with caution due to the important heterogeneity of the studies included in this meta-analysis. Further trials are still needed to confirm the current findings.
