《英国医学杂志》一篇研究报告指出,1970年男子精子数比1959年减少了1/4;在过去40年中,男子精子以平均每年2.1%的速度减少;丹麦学者在21个国家调查了1.5万名男性精液中精子数目,发现只有50年前的1/2。按生理要求,在1毫升精液中要含有4000万到1.2亿个精子才算正常,如果每毫升少于2000万个精子,就难以生育;更何况精子的质量也在减退,畸形、质量低劣的精子比例增多,精子活力、穿透力、致孕率在下降,以致男性不育的比例正在逐步增加。纽约市身体研究基金会卡塔来医师说:1960年因不育症前来咨询的男性为8%,如今已达到40%以上。无论是谁,听到这样惊人的数字后都会感到吃惊:为什么精子会面临这种局面?怎样调整才能使精子的数量和质量保持正常?
A study in the British Medical Journal noted that the number of sperm in men was reduced by a factor of 1/4 in 1970 compared to 1959; in the past 40 years, men’s sperm decreased at an average rate of 2.1% per year; Danish scholars investigated in 21 countries The number of sperm in 15,000 men’s semen was found to be only 1/2 of 50 years ago. According to physiological requirements, in 1 ml of semen to contain 40 million to 120 million sperm to be considered normal, if less than 20 million sperm per milliliter, it is difficult to bear children; not to mention the quality of sperm is also diminished, deformity, poor quality Sperm increased, sperm motility, penetration, pregnancy rate is declining, so that the proportion of male infertility is gradually increased. Kathleen, MD, of the New York City Body Research Foundation, said that in 1980, 8% of men were counseled for infertility and now have more than 40%. No matter who, will be surprised to hear such a staggering number: Why sperm will face this situation? How to adjust the number and quality of sperm to maintain normal?
