RESUMEN
ETHNOPHARMACOLOGICAL RELEVANCE: Diminished ovarian reserve (DOR) results in reduced fertility. Kuntai capsule, a Chinese patent medicine, which can nourish the heart and kidneys, has shown promising efficacy in its treatment. However, there is no enough clinical evidence to confirm the efficacy and safety of Kuntai capsule. AIM OF THE STUDY: This review aims to evaluate Kuntai capsule's potential benefits and detriments for diminished ovarian reserve. MATERIALS AND METHODS: Databases namely China National Knowledge Infrastructure, WANFANG Database, Chinese Science and Technology Journal Database, Chinese Biomedical Literature Database, PubMed, Cochrane Library, and Embase were searched from their inception to July 2023. We included randomized controlled trials (RCTs) comparing Kuntai capsule to hormone therapy (HT) and Kuntai capsule in combination with HT to HT alone for DOR treatment. The risk of bias was evaluated using RoB 1.0. A Meta-analysis was performed using RevMan 5.4 software. The primary outcomes were antral follicle count (AFC) and serum anti-Müllerian hormone (AMH), secondary outcomes were follicle-stimulating hormone (FSH) and adverse reactions. RESULTS: A Meta-analysis of 12 randomized controlled trials (RCTs), encompassing a total of 905 DOR patients was conducted. The results indicated that the combination of Kuntai capsule with HT exhibited superior efficacy in enhancing AFC (MD = 1.34, 95% CI [0.96,1.72]) and AMH levels (MD = 1.09 (ng/mL) 95% CI[0.80,1.38]), Kuntai capsule demonstrated improvements in AFC (MD = 0.65, 95% CI [0.48,0.83]) in DOR patients compared to HT alone. CONCLUSIONS: Based on the available results, the combination of Kuntai capsule with HT appears to improve the AFC, AMH and FSH levels of DOR patients. Kuntai capsule alone appears to improve the AFC and FSH levels of DOR patients. However, included trials had methodological quality issues, further standardized research is required.
