BACKGROUND
Semen quality significantly influences conception, and its preservation is crucial for couples seeking pregnancy. We investigated dietary and lifestyle risk factors impacting semen quality.
METHODS
A total of 466 males from the Guangzhou Women and Children's Medical Center's pre-pregnancy consultation clinic were recruited between January 2021 and March 2023 for inclusion. Semen analysis was performed, and diet and lifestyle data were gathered via questionnaire. Logistic regression was utilized to examine the link between diet, lifestyle variables, and semen quality.
RESULTS
Smoking worsened progressive sperm motility (38.0% vs. 36.0%, t = 2.262; P = 0.049). Alcohol consumption impaired progressive motility (40.5 ± 17.8% vs. 34.7 ± 16.1%, t = 3.396; P < 0.001) and total motility (56.0% vs. 64.0%; P = 0.001). Using plastic beverage bottles for oil or seasonings lowered sperm concentrations (40.4% vs. 59.0% vs. 65.5%; P = 0.032). A sweet diet correlated with higher total sperm motility (55.0% vs. 60.0%, 62.0% vs. 63.2%; P = 0.017). Higher milk product intake improved sperm concentration (41.610 vs. 63.710 vs. 66.1*10; P = 0.021) and motility (54.5% vs. 56.0% vs. 63.0%; P = 0.033). More frequent egg consumption increased semen volume (3.1 mL vs. 3.8 mL vs. 4.0 mL; P = 0.038). Roughage intake enhanced sperm concentration (160.810 vs. 224.610; P = 0.027), and adequate sleep improved progressive sperm motility rate (35.4% ± 18.2% vs. 40.2 ± 16.3%, F = 3.747; P = 0.024) and total motility (52.7% vs. 61.5%; P = 0.013). The regression model showed that using plastic containers for condiments was a protective factor for semen volume (OR: 0.12; CI 0.03-0.55; P = 0.006), sperm concentration (OR: 0.001, CI 0.00-0.30; P = 0.012), and count (OR: 0.12, CI 0.03-0.48; P = 0.003). Milk and egg consumption were also protective for semen volume (OR: 0.18, CI 0.06-0.51; P = 0.001 and OR: 0.11, CI 0.03-0.55; P = 0.006, respectively), while sufficient sleep benefitted total sperm motility (OR: 0.47, CI 0.24-0.95; P = 0.034).
CONCLUSIONS
Smoking and drinking, type of condiment container, diet preference, sleep duration, and milk, roughage, and egg consumption may reduce semen quality.
背景
精液质量对受孕有重要影响，因此保存精液质量至关重要。我们研究了影响精液质量的饮食和生活方式相关风险因素。
方法
2021 年 1 月至 2023 年 3 月期间，我们招募了广州妇女儿童医疗中心孕前咨询诊所的 466 名男性。进行精液分析，并通过问卷收集饮食和生活方式数据。使用逻辑回归分析饮食、生活方式变量与精液质量之间的关系。
结果
吸烟使精子前向运动能力变差（38.0%比 36.0%，t=2.262；P=0.049）。饮酒损害精子前向运动能力（40.5±17.8%比 34.7±16.1%，t=3.396；P<0.001）和总运动能力（56.0%比 64.0%；P=0.001）。使用塑料饮料瓶盛装油或调味料会降低精子浓度（40.4%比 59.0%比 65.5%；P=0.032）。甜食与总精子运动能力较高相关（55.0%比 60.0%，62.0%比 63.2%；P=0.017）。增加乳制品的摄入可提高精子浓度（41.610比 63.710比 66.1*10；P=0.021）和运动能力（54.5%比 56.0%比 63.0%；P=0.033）。增加鸡蛋摄入可增加精液量（3.1ml比 3.8ml比 4.0ml；P=0.038）。增加膳食纤维摄入可提高精子浓度（160.810比 224.610；P=0.027），充足的睡眠可提高精子前向运动能力（35.4%±18.2%比 40.2%±16.3%，F=3.747；P=0.024）和总运动能力（52.7%比 61.5%；P=0.013）。回归模型显示，使用塑料容器盛装调味料是精液量（OR：0.12；CI 0.03-0.55；P=0.006）、精子浓度（OR：0.001，CI 0.00-0.30；P=0.012）和精子计数（OR：0.12，CI 0.03-0.48；P=0.003）的保护因素。牛奶和鸡蛋的摄入也对精液量（OR：0.18，CI 0.06-0.51；P=0.001 和 OR：0.11，CI 0.03-0.55；P=0.006）有保护作用，而充足的睡眠有益于总精子运动能力（OR：0.47，CI 0.24-0.95；P=0.034）。
结论
吸烟和饮酒、调味料容器类型、饮食偏好、睡眠时长以及牛奶、膳食纤维和鸡蛋的摄入可能会降低精液质量。
