Contraception is the practice of stopping a pregnancy from starting when two people have sex — and, by extension, the whole set of methods people use for that. It is the idea and the habit, not one object.

Contraception Contraception（避孕） is the practice of stopping a pregnancy from starting when two people have sex是指在兩個人發生性行為時，阻止懷孕發生的做法—— and, by extension, the whole set of methods people use for that引申開來，也指大家用來達到這個目的的所有方法。 It is the idea and the habit這是一種概念和習慣， not one object不是指某一樣東西。

Methods include the pill, condoms, an IUD, an implant, and others; some work in the body, some are used at the time. People also talk about contraception in public health and in sex education: access to it, teaching about it, whose job it is.

Methods include the pill, condoms, an IUD, an implant, and others方法包括口服避孕藥、保險套、子宮內避孕器、植入式避孕器等等； some work in the body有些是在體內發揮作用， some are used at the time有些是當下使用的。 People also talk about contraception in public health and in sex education大家也會在公共衛生和性教育的話題裡談到contraception： access to it像是能不能取得， teaching about it該怎麼教， whose job it is這是誰的責任。

The word is neutral and adult; you hear it from doctors, teachers, and in news more than in very casual chat, where people often name the method instead (“Are you on the pill?”).

The word is neutral and adult這個字是中性、成熟的用詞； you hear it from doctors, teachers, and in news常從醫生、老師口中，或在新聞裡聽到 more than in very casual chat比較不會出現在很隨性的聊天裡， where people often name the method instead那種場合大家通常會直接講方法 ("Are you on the pill?")（像是「Are you on the pill?」你有在吃避孕藥嗎？）。

It does not mean abortion. Abortion ends a pregnancy that has already begun; contraception tries to stop one from beginning.

It does not mean abortion這不等於abortion（墮胎）。 Abortion ends a pregnancy that has already begunAbortion是終止已經開始的懷孕； contraception tries to stop one from beginningcontraception則是想辦法不讓懷孕開始。
