Their role in health and disease is to influence different aspects of cell biology and to act as intermediaries between cells. Follicular fluid exosomes or extracellular vesicles (FF-EVs) secreted by ovarian granulosa cells are critical mediators of ovary growth and maturation. The movement and proteins of these exosomes are crucial in the regulation of cellular communication and the aging of cells, a process termed inflammaging. Menopause, a natural progression in the aging of females, is often accompanied by numerous negative symptoms and health issues.

The etiological and pathological mechanisms of diminished ovarian reserve (DOR) remain unclear, and no reliable treatment is currently available for DOR.

The concentrations of adipokines and cytokines in FF from individual follicles of women with DOR undergoing in vitro fertilization (IVF) were studied.

Randomized controlled trials (RCTs) comparing NPIs with other NPIs or placebo treatments in adult women with PCOS were included. Study selection was independently performed by three authors. Quality assessment followed PRISMA guidelines using the Cochrane RoB2 tool. The confidence of evidence was examined using Confidence in Network Meta-Analysis (CINeMA). Traditional meta-analysis of continuous variables was conducted using Stata 17.0 software with a random-effects model, reporting effect sizes as standardized mean differences (SMD) and weighted mean differences (WMD). Network meta-analysis (NMA) was used to synthesize data, with network diagrams illustrating comparisons between NPIs. We assessed the consistency of the results, performed sensitivity analyses, and examined publication bias to evaluate the influence of individual studies. Furthermore, subgroup analysis and network meta-regression analysis were conducted to explore potential sources of heterogeneity.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Results: &lt;/strong&gt;The review included 21 studies with 1,196 participants, with meta-analysis focusing on 17 studies involving 1,013 participants. NPIs significantly reduced serum testosterone (SMD = -0.57; 95% CI: -0.86 to -0.29, p &lt; 0.01), A4 (SMD = -1.37; 95% CI: -2.63 to -0.12, p = 0.03), and mFG score (WMD = -0.81; 95% CI: -1.26 to -0.37, p &lt; 0.01). Notably, the reduction in testosterone levels achieved with NPIs met the Minimum Clinically Important Difference (MCID) of 12.47 ng/dL (WMD = -12.57; 95% CI: -18.92 to -6.23; p &lt; 0.01), affirming the clinical relevance of these reductions. No significant effects were observed on Free Androgen Index (FAI), Sex Hormone-Binding Globulin (SHBG), Dehydroepiandrosterone (DHEA), DHEA Sulfate (DHEAS), Free Testosterone (FT), or Dihydrotestosterone (DHT) levels (all p &gt; 0.05). The NMA (18 studies, 1,067 participants) identified electroacupuncture combined with diet and exercise as the most effective intervention for reducing serum testosterone (WMD = -21.75; 95% CI: -49.58 to 6.07; SUCRA 72.3%).
