皮下埋植杆
許多國家都運用皮下埋植杆避孕，商品名各異。按照產品品名不同，皮下埋植杆由一個或數個火柴狀大小的杆棒所組成。它（們）在局麻下被包埋在上臂的皮下，持續釋放與避孕藥相似的激素，並借此防止可能的受孕。皮下埋植杆可以在皮下放置數年，這是該避孕方法的極大優點所在，對那些每天服用避孕藥不方便的女性極為適用。另一方面，皮下埋植杆並不適用於每一個女性，而且某些成品已經顯示有討厭的副作用。簡而言之，需要在醫囑和醫生的監察下才能夠使用該方法。
避孕效果：對體重輕於70千克(150磅)的婦女非常有效；對超過該體重的婦女效果略差。
避孕有效率：幾乎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. |
