避孕
避免懷孕最顯而易見和最可靠的方法是禁絕性交。可是,有史以來人們已經尋求到了避孕的方法,也就是那種讓人們參與性交而不冒作父母風險的方法或裝置。數千年以來,就像人們所發現的那樣,這樣的方法仍然是不成熟的和效果極其有限的。最終,現代科學家發現了新的較為有效的方法(和對舊方法作了改進的方法),迄今為止,科學家對避孕方法有了非常多的選擇。今天,我們幾乎能夠完全防止非意願妊娠的發生。不過,更安全、更簡捷和更便宜的避孕藥具的研製仍將繼續著。
Contraception
The most obvious and most reliable way of avoiding pregnancy is complete abstinence from coitus. However, throughout history women and men have searched for means of contraception, i.e., for methods or devices that would allow them to engage in coitus without the risk of becoming parents. For thousands of years, such methods as were found remained crude and largely ineffective. Eventually, modern scientists discovered new and better methods (and improved the old ones), until they arrived at the present wide range of reasonable choices. Today, unwanted pregnancies can be prevented with almost complete certainty. Nevertheless, the search for even safer, simpler, and cheaper contraceptives goes on.
