人们习惯于用各种数字来评价自己的生活。近日,美国《男性健康》杂志报道,男人一生的性健康也有一组“数字指标”。每次射出的精液量有1～2茶匙(5毫升)。每茶匙精液的热量达7卡路里,而一罐250毫升可乐的热量有150卡路里。美国泌尿外科学家海特罗那博士提供了一个简便的自我测量法:量出5毫升水,倒入一个干净的避孕套内,记住水的位置,这样就能估计自己的射精量了。如果达到5毫升,说明你的前列腺非常健康。 People are accustomed to using various numbers to evaluate their own lives. Recently, the United States, “Men’s Health” magazine reported that a man’s sexual health also has a set of “digital indicators.” Each injection of semen volume 1 to 2 teaspoons (5 ml). There are 7 calories per teaspoon of semen and 150 calories for a 250 ml coke. Dr. Heterodia, a U.S. urologist, offers a simple self-measurement: take 5 ml of water, pour it into a clean condom, and remember the location of the water so that you can estimate your own amount of ejaculation. If you reach 5 ml, that your prostate is very healthy.
