Spermicides are regularly used in conjunction with obstacle methods. They are chemical barriers which can also be supplied on your own.
You are watching: Which of the following statements about barrier methods of contraception is false?
In this research session, you will certainly learn around the various barrier methods, their varieties and mechanism of actions, their efficiency of use, and also the advantages and disadvantages of each.
Learning Outcomes for study Session 8
When you have actually studied this session, you must be maybe to:
8.1 Define and use correctly every one of the key words printed in bold. (SAQs 8.1 and 8.6)
8.2 explain the species of obstacle contraceptives. (SAQs 8.2 and also 8.6)
8.3 describe the mechanism of action, use, effectiveness, advantages and defect of the masculine condom. (SAQs 8.2, 8.3, 8.4 and 8.6)
8.4 explain the use, advantages and flaw of the mrs condom. (SAQs 8.5 and 8.6)
8.5 talk about the use, advantages and disadvantages of making use of diaphragms. (SAQ 8.6)
8.6 describe the mechanism of action, efficiency and advantages of spermicides. (SAQ 8.6)
8.1 Types the barriers
Barrier contraceptives are broadly classified into two main types: mechanically barriers and also chemical barriers.
8.1.1 Mechanical barriers

The condom is the just contraceptive technique that helps avoid sexuallytransfer infections (STIs).
8.1.2 Chemical barriers
Chemical barriers or spermicides room sperm-killing substances, available as foams, creams, gels, movies or suppositories, which are frequently used in female contraception in conjunction through mechanical barriers and other devices. Spermicides space usually easily accessible without a prescription or clinical examination.
8.2 The masculine condom
The masculine condom is just one of the many widely used obstacle methods in the world. In Ethiopia, it has perhaps to be the only barrier technique ever known and used. Thus, in this study session, much more emphasis will certainly be given to the masculine condom 보다 to any other barrier technique and you will learn about it in detail.
