What factors affect the efficiency of spermicide?
The efficacy of spermicide is reduced by improper use, its use without another method of controlling contraception, time and douching. Another thing that can disrupt efficiency is the variety of application methods. It may also be difficult to remember this contraceptive, which must be used before sexual intercourse and has several minutes of waiting time that disrupts spontaneity. Because perfection is rarely possible, more accurate estimates are provided by a number of family planning agencies. According to these interpretations of the real world, about 26% of women become pregnant when they use this method independently. Approximately 42% of pregnancies, while women use this method is counted by errors. These can arise from the failure of the full -pipe OW, incorrect location, use too little or for many other reasons. Every type, such as vaginal film, suppositories, foam and jelly, can have completely different directions. People who learn how to use a condom can easily switch between brands, but change the type of spermicidal product may increaseIT chance of a human mistake.
When used as further safety measures with membranes, condoms or cervical caps, the spermicide is very useful and can reduce the chances of pregnancy. Most family planning experts recommend its use in conjunction with another method to ensure greater pregnancy. Since it is not intended for use separately, the absence of a second barrier, such as a condom, basically reduces the efficiency of spermicide. It is better used as one element in a two -piece system.
time plays an important role in the efficacy of spermicide in several ways. Women usually have to wait 10-15 minutes for this contraception to work. In addition, most spermicides lose their effectiveness after an hour. At this point, more must be used to maintain protection.
Inability in gel, cream or foam for six hours can also cause problems. Douching after sexual intercourse is fromVláště discouraged because it undoubtedly reduces the efficacy of spermicide. Spermicidal products also have validity expiration data and do not work if it has expired.
Forgotten to use spermicide over time will cancel its effect. Because it is a method that requires at least a few minutes of planning, there is a concern that it will not always be used in moments of impetiosity. 10-15 minutes of waiting plus time of application may seem too long, especially if one is tired or there is an enormous encounter. Some people are natural planners and assume that they will always have time to prepare, but others may prefer a more effective method that works continuously or is used with greater ease.
