摘要The incidence of infertility has recently risen.Semen quality is an important male fertility indicator,and dietary factors can affect semen quality.We conducted this systematic review and meta-analysis to determine the effects of healthy dietary patterns on semen quality.A literature search was conducted in 3 databases(Embase,Web of Science and PubMed)on August 21,2021.The included cross-sectional studies examined the influence of the Mediterranean,Dietary Approaches to Stop Hypertension(DASH),and prudent diet patterns on semen quality parameters;six studies(1244 subjects)were included.By comparing high consumption with low consumption of healthy dietary patterns,the results of the meta-analysis showed significantly higher sperm concentrations(mean difference[MD]=6.88×106 ml-1,95％confidence interval[CI]:1.26×106 ml-1-12.49×106 ml-1;P＜0.05),a significant increase in total sperm count(MD=16.70×106,95％Cl:2.37×106-31.03×106;P＜0.05),and a significant increase in progressive sperm motility(MD=5.85％,95％Cl:2.59％-9.12％;P＜0.01).The sperm concentration,progressive sperm motility,and total sperm count were significantly higher in men with higher versus lower consumption of healthy dietary patterns.However,the results must be interpreted with caution.
