陰道隔膜與殺精子凝膠劑
陰道隔膜是一種柔韌、碗狀和由橡膠製成的小裝置；它被放置於靠近子宮頸，起機械性阻塞精子作用，以防止其進入子宮。為了增加其避孕效果，陰道隔膜要與殺精子膏或凝膠劑一起使用，一般殺精子膏塗在陰道隔膜的輪緣。因為不同的婦女個頭各異，成品的陰道隔膜型號大小也各異，必須由醫生給使用者量度子宮頸尺寸，以確定使用的型號(使用者應該每兩年和每次懷孕後再檢測一次)。醫生也會傳授如何合適地將隔膜插入陰道。
性交之前6小時就得將陰道隔膜插入陰道，性交之後至少8小時就必須取出；如果在8小時之內還想性交，必須在陰道內塗入更多的殺精子膏或凝膠劑(當然，勿需取出陰道隔膜)。隔膜取出後，用肥皂和清水清洗，存放待用。
避孕效果：當與殺精子凝膠劑和乳膏合用時，非常有效。 |

Diaphragm and Jelly
The diaphragm is a small, flexible, bowl-shaped device made of rubber that fits closely over the cervix, where it mechanically blocks the sperm cells from entering the uterus. In order to increase its effectiveness, the diaphragm is used together with a spermicidal jelly or cream, which is put inside it and spread around its rim. Since different women are built differently, diaphragms come in different sizes and have to be fitted by a doctor. (A woman should be rechecked for size every two years and after each pregnancy.) The doctor will also teach the woman how to insert the diaphragm properly.
The diaphragm is inserted up to six hours before sexual intercourse and must be left in place for at least eight hours afterwards, if the couple wants to engage in coitus again before that time, more cream or jelly must be inserted into the vagina (without removing the diaphragm, of course). After the diaphragm has been removed, it is washed with soap and water and can be used again.
Effectiveness: very effective when used with spermicidal jelly or cream. |
