    根据美国生殖医学协会的统计，在美国有六百万民众受不育症影响，其中男性不育症数量占不育问题的40%，15%的夫妇深受其害。

    研究表明许多营养成分可以提高精子数量及活力，如锌、硒、维生素B₁₂、肉碱和精氨酸。此外已证明许多具有抗氧化功能的营养成分对治疗男性不育有益，如谷胱甘肽、辅酶Q₁₀、维生素A和E。

    一项新的小型研究探讨了补充维生素C对男性不育影响，其结果发表在《药用食品杂志》上。该研究的参试者由13名年龄在25至35岁之间的男子职组成。受试者每日补充维生素C1000mg，分两次服用，持续2个月。

    维生素C可保护精子免受氧化破坏，且能增强吸烟者的精子质量。研究发现一天补充1克维生素C还能改善精子的凝集状态。研究者还注意到缺乏维生素C的男性很有可能因为精子的损伤而导致生育缺陷。目前有几个研究已表明，补充维生素C能显著提高精子质量。

    研究结果显示衡量精子质量的三个参数有了显著的提高：精子活动率几乎翻了两倍，从31%增加至60%；总精子量的增加为原来的两倍还多；而正常精子率则从43%增加至67%。

    研究者的结论是：试验表明维生素C的应用对不育男性患者有益。

    维生素C是一种水溶性维生素，具有强大的抗氧化作用，参与了肌肉和血管所需的胶原合成，对于创伤愈合非常重要，并且是一种天然的抗组胺剂。维生素C的有益作用可能归功于其抗氧化活性，此外进一步的双盲控制研究证实了这个初步的研究结果。

Vitamin C supplements help reverse male infertility

Roman Bystrianyk, "Vitamin C supplements help reverse male infertility", Health Sentinel, October 5, 2006,

According to the American Society for Reproductive Medicine, infertility affects over 6 million people in the United States. Male infertility accounts for 40% of infertility problems, which affects approximately 15% of couples.

A number of nutritional approaches have been shown to improve sperm counts and sperm motility, such as zinc, selenium, vitamin B12, carnitine, and arginine. Also, numerous antioxidant nutrients have also proven beneficial in treating male infertility, such as glutathione, coenzyme Q10, and vitamins A and E.

A new small study published in the Journal of Medicinal Food examined the effect of supplementing with vitamin C on men with infertility. The study consisted of 13 men aged 25 to 35 who supplemented with 1,000 mg of vitamin C twice daily for 2 months.

Vitamin C protects sperm from oxidative damage and has been shown to improve sperm quality in smokers. One gram of vitamin C daily has also been found to be effective in agglutination, a condition that causes sperm to clump together. The study authors notes 搈en who lack vitamin C are also more likely to pass on genetically damaged sperm that can cause birth defects.? Several studies have shown that supplementation with vitamin C shows a significant improvement in sperm quality.

At the end of the study the there was a significant improvement in three parameters for measuring sperm quality. The percentage of motile sperm almost doubled from 31% to 60%, the total sperm count more than doubled, and the percentage of normal sperm increased from 43% to 67%.

The authors conclude, this trial has demonstrated the beneficial use of vitamin C in infertile male patients. Vitamin C is a water-soluble vitamin and powerful antioxidant that is needed to make collagen for muscles and blood vessels. It is important for wound healing and acts as a natural antihistamine. The beneficial effects of vitamin C might be ascribed to its antioxidant activity. Further blinded controlled studies are warranted to substantiate the results of this preliminary pilot study.?
