男性科博士生导师徐福松教授最近指出,人类的精子密度已由1940年的每毫升1.13亿个下降到1990年的0.66亿个;每次射精量由3.4毫升下降至2.75毫升。徐教授说:“照这样下去,100年后的男子汉将难以生育。” 另有报道,医学调查证实,男子患不育症的日益增多,而且城市高于农村。在我国,农村男子患不育症的占4％—5％,城镇男子约7％;在工业发达、人口稠密的城市,男子不育患者约10％。 医学家最近的研究结果表明,不正确的生活方式是影响男性生育能力的主要原因。
Professor Xu Fusong, a male doctoral tutor, recently pointed out that human sperm density has dropped from 113 million per milliliter in 1940 to 66 million in 1990; the number of ejaculations has dropped from 3.4 milliliters to 2.75 milliliters per ejaculation. Professor Xu said: “In the light of this, 100 years later men will have difficulty in giving birth.” In a separate report, medical investigations confirmed that men were suffering from an increasing number of infertility and that cities were higher than in rural areas. In China, rural men suffer from infertility accounts for 4% -5%, urban men about 7%; in the industrially developed and densely populated cities, about 10% of male infertility patients. Recent findings of medical scientists show that incorrect lifestyle is the main reason that affects male fertility.
