皮下埋植杆
许多国家都运用皮下埋植杆避孕，商品名各异。按照产品品名不同，皮下埋植杆由一个或数个火柴状大小的杆棒所组成。它（们）在局麻下被包埋在上臂的皮下，持续释放与避孕药相似的激素，并借此防止可能的受孕。皮下埋植杆可以在皮下放置数年，这是该避孕方法的极大优点所在，对那些每天服用避孕药不方便的女性极为适用。另一方面，皮下埋植杆并不适用于每一个女性，而且某些成品已经显示有讨厌的副作用。简而言之，需要在医嘱和医生的监察下才能够使用该方法。
避孕效果：对体重轻于70千克(150磅)的妇女非常有效；对超过该体重的妇女效果略差。
避孕有效率：几乎100%。 |

Implants
Contraceptive implants are available in many countries and under different brand names. Depending on the product, they consist of one or several small, matchstick-size rods that are implanted in the upper arm under local anesthesia. They continuously release hormones similar to those used in contraceptive pills and thus prevent possible conceptions. They can stay in place for several years. This is their great advantage for women who have trouble taking their pills every day. On the other hand, implants are not for every woman, and some versions have had unpleasant side effects. In short, a doctor’s advice and supervision are essential for this method.
Effectiveness: Very effective for women weighing less than 70 kg (150 pounds), somewhat less for women weighing more.
Effectiveness: almost 100 percent. |
