避孕

避孕方法:不用医学协助的方法

勿需医生处方,我们有四种避孕方法可用:禁绝性交(Abstinence from coitus阴茎退离或体外排精避孕法withdrawal coitus abruptus)、避孕套(condom)和杀精子剂(spermicides。在有一些国家,当打算勿需处方即可使用,则可以增加到第五种方法,那就是性交后避孕药post-coital contraception),也叫紧急避孕药事后避孕药
有一些专家一度说使用任何的避孕方法比根本不使用要好。可是,某些避孕方法是如此地达不到预期效果以至于在实践中无甚用处。其中有一种叫karezza,也叫保留性交(coitus reservatus),是一种在性交中有意设法不射精的的方式。尽管这种尝试可能有着情感甚至精神交流的价值,但是并不必定会防止怀孕。另有一种可疑的方法,将蘸有杀精子粉末或剂的小片海绵插入阴道。这种做法不仅无效,而且也可能干扰性交和导致不适。还有一种方法,叫性交后阴道灌洗,既为抱着祛除精子的希望,用某种液体清洗阴道。这种清洗过程不能避孕,因为清洗不足以祛掉已经进入阴道的精子。进一步地,有某些女用卫生清洗产品,被广告暗示有避孕作用。然而它们并无所宣称的那些个作用,而且实际上对阴道组织还有害。一般而言,应该要避免阴道灌洗和喷雾,因为这是多此一举。阴道会以自身的分泌液来达到自洁。对阴道过多的干预只能破坏其微生态环境和导致感染或发炎。

Contraception

Methods of Contraception: Without Medical Assistance

There are four methods of contraception which can be used without any professional help: Abstinence from coitus, withdrawal (coitus abruptus), condom, and spermicides. In some countries a fifth method may soon be added, as there are plans to make "post-coital contraception", also called “emergency contraception” or "morning-after pills", available without prescription
Some experts have said in the past that any method of contraception is better than none at all. However, some methods are so ineffective as to be practically useless. Among these is karezza, or coitus reservatus, a form of coitus in which the man tries to avoid ejaculation. Although such an attempt may have certain emotional and even spiritual values, it does not necessarily prevent pregnancies. Another questionable method consists of inserting a small sponge together with some spermicidal powder or liquid into the vagina. This is not only ineffective, but may also interfere with coitus and cause discomfort. Still another method is vaginal douching after coitus or, in other words, the washing out of the vagina with some sort of solution in the hope of removing the sperm. This procedure is useless because it can never come soon enough to make any difference. There are further certain "feminine hygiene" products which are advertised with hints at contraceptive powers. Nevertheless, they are quite ineffective in that respect and may actually be harmful to the vaginal tissue. In general, vaginal douching and spraying should be avoided because it is unnecessary. The vagina cleanses itself with its own secretions. Too much interference can only upset the vaginal ecology and cause infection or irritation.
