避孕套作为一种物理屏障,可以隔离男女性交时的体液接触。所以,当80年代艾滋病开始流行后,它就想当然地被推荐为预防艾滋病的措施。甚至有人出于商业目的,极端夸大地鼓吹它百分之百有效,然而事实并非如此。十多年来,不少严肃的学者通过研究和分析,发现避孕套预防性病和艾滋病的效果很不可靠。例如避孕套预防淋病的相对风险为25%～50%,女性则更糟,为66%～87%;其用于预防尖锐湿疣、生殖器疱疹、衣原体感染基本上是无效的。西方在大力提倡使用避孕套的情况下,淋病发病率确实有所下降,而尖锐湿疣、生殖器疱疹、衣原体感染却越来越多。欧美成年人70%以上患过性病,美国16～40岁的青壮年中,60%患有生殖器疱疹。生殖器疱疹是一种不能根治的性病,少则每年发作5～6次,多则发作10余次。一旦受感染,终身遭受痛苦,还可诱发恶性肿瘤。 As a physical barrier, condoms can isolate the body fluid contact between men and women during sexual intercourse. So when the AIDS epidemic began to take hold in the 1980s, it was taken for granted as a measure to prevent AIDS. It is even claimed for commercial purposes that it is extremely exaggerated to promote it 100% effective, but this is not the case. For more than a decade, many serious scholars, through research and analysis, have found that condoms have a very unreliable effect of preventing STDs and AIDS. For example, condoms prevent gonorrhea relative risk of 25% to 50%, women are even worse, 66% to 87%; its for the prevention of genital warts, genital herpes, chlamydial infection is essentially ineffective. Western strongly advocated the use of condoms in the case, the incidence of gonorrhea did decline, and genital warts, genital herpes, chlamydia infections are more and more. More than 70% of adults in Europe and the United States have sexually transmitted diseases. In the young adults aged 16 to 40 in the United States, 60% have genital herpes. Genital herpes is a stubborn venereal disease, ranging from attack 5 to 6 times a year, as many as more than 10 episodes. Once infected, life-long suffering, but also induce malignant tumors.
