Abstract

Background: In this paper, a meta-analytical approach was used to test the effect of exercise on the relevant indicators of fertility in young men, with a view to providing a scientifically sound exercise intervention program for male fertility.

Method: We systematically searched PubMed, MEDLINE, PsycINFO, SportDiscus, Web of Science, CNKI (China National Knowledge Infrastructure), and Wanfang Database for randomized controlled trials and quasi-experimental studies examining the relationship between exercise and male fertility, with the search conducted up to July 31, 2025. Primary outcomes were semen concentration and sperm motility; secondary outcomes included testosterone, pregnancy rate, and live birth rate. Review Manager 5.3 was used for risk of bias assessment, heterogeneity testing, subgroup/effect size analysis, and sensitivity analysis.

Results: (1) A total of 10 studies were included (n = 1511). (2) Exercise was effective in improving semen concentration (SMD=0.35, 95% CI (0.16, 0.54), P < 0.001), sperm motility (SMD = 0.79, 95% CI (0.31, 1.28), P < 0.01), testosterone (SMD = 1.21, 95% CI (0.84, 1.58), P < 0.001), pregnancy rate in young men (RR, 12.60; 95% CI (2.43, 65.35); P < 0.01), live birth rate (RR, 1.90; 95% CI (1.04, 3.46); P < 0.05), and other fertility-related indicators. (3) Three to four times/week (SMD = 0.51, 95% CI (0.12, 0.90), P < 0.05), 30-60 min per intervention (SMD=0.34, 95%(0.14, 0.54), P < 0.001), and duration of 2-8 weeks (SMD = 0.70, 95% CI (0.14, 1.26), P < 0.05), moderate-intensity (SMD = 0.36, 95% CI (0.06, 0.67), P < 0.05) exercise was more effective as an intervention for semen concentration in young men. (4) Three to four times/week (SMD = 1.01, 95% CI (0.60, 1.42), P < 0.001), with a duration of 30-60 min per intervention (SMD = 0.76, 95% CI (0.19, 1.33), P < 0.05), and lasting 9-16 weeks (SMD = 0.66, 95% CI (0.16, 1.15), P < 0.01), moderate-intensity (SMD = 0.82, 95% CI (0.16, 1.48), P < 0.05) exercise was optimal for sperm motility intervention in young men.

Conclusion: Moderate exercise can increase semen concentration, sperm motility, and testosterone levels in men, increasing pregnancy rates and the number of live births. The ideal exercise intervention program to improve men's reproductive health consists of moderate exercise for 3-4 sessions per week, lasting 30-60 min each, over a total of 2-8 weeks.

运动干预对年轻男性生育相关指标的影响：系统回顾和荟萃分析。

背景：本文采用荟萃分析方法检验运动对青年男性生育相关指标的影响，以期为男性生育提供科学合理的运动干预方案。方法：系统检索PubMed、MEDLINE、PsycINFO、SportDiscus、Web of Science、CNKI、万方数据库，检索截止到2025年7月31日的关于运动与男性生育能力关系的随机对照试验和准实验研究。主要结局是精液浓度和精子活力；次要结局包括睾酮、妊娠率和活产率。采用Review Manager 5.3进行偏倚风险评估、异质性检验、亚组/效应量分析和敏感性分析。结果：(1)共纳入10项研究（n = 1511）。(2)运动可有效提高精液浓度(SMD=0.35, 95% CI (0.16, 0.54)， P结论：适度运动可提高男性精液浓度、精子活力和睾酮水平，提高妊娠率和活产数。改善男性生殖健康的理想运动干预方案包括每周3-4次适度运动，每次持续30-60分钟，总共2-8周。

期刊介绍： The International Journal of Behavioral Medicine (IJBM) is the official scientific journal of the International Society for Behavioral Medicine (ISBM). IJBM seeks to present the best theoretically-driven, evidence-based work in the field of behavioral medicine from around the globe. IJBM embraces multiple theoretical perspectives, research methodologies, groups of interest, and levels of analysis. The journal is interested in research across the broad spectrum of behavioral medicine, including health-behavior relationships, the prevention of illness and the promotion of health, the effects of illness on the self and others, the effectiveness of novel interventions, identification of biobehavioral mechanisms, and the influence of social factors on health. We welcome experimental, non-experimental, quantitative, qualitative, and mixed-methods studies as well as implementation and dissemination research, integrative reviews, and meta-analyses.
