1 BARRIER METHODS OF CONTRACEPTIVES Prepared by: Mr’s Raheegeh Awni 05/10 /2012

2 BARRIER METHODS OF CONTRACEPTIVES Barrier methods of contraception prevent the transport of sperm to the ovum, immobilize sperm, or are lethal against sperm.

3 Male and Female Condoms The male condom offers a viable means of contraception when used consistently and properly Acceptance has been increasing as a growing number of men are assuming responsibility for regulation of fertility.


5 Male condoms are usually made of latex rubber. They are cheap and are widely available for purchase or free from many clinics. They have been heavily promoted in the Safe Sex campaign to prevent the spread of sexually transmitted diseases (STDs), particularly human immunodeficiency virus (HN) and acquired immunodeficiency syndrome (AIDS).

6 Couples using condoms should be aware of the availability of emergency contraception Some men and women may be allergic to latex condoms or spermicide, and hypoallergenic latex condoms and plastic male condoms are available.

7 USE The condom is applied to the erect penis, rolled from the tip to the end of the shaft, before vulvar or vaginal contact. A small space must be left at the end of the condom to allow for collection of the ejaculate, so that the condom will not break at the time of ejaculation. If the condom is dry, a water-soluble lubricant such as K-Y jelly should be used to prevent irritation and possible condom breakage.

8 ADVANTAGES small, disposable, and inexpensive; it has no side effects, requires no medical examination effective. silicone rubber condoms are available for individuals allergic to latex( lamb’s intestines), offer protection against both pregnancy and sexually transmitted infections (STIs).

9 disadvantages. Breakage, displacement, perineal or vaginal irritation, dulled sensation are possible

10  Couples should be careful when removing the condom after intercourse.  For optimal effectiveness the man should hold the condom rim to prevent spillage. and to prevent the condom from slipping off.

11 Female barrier The diaphragm, or Dutch cap, is the female barrier used most commonly in the UK Other female barriers include cervical caps, vault caps and vimules. They should all be used in conjunction with a spermicidal cream or gel.


13 female condom The Reality female condom is a thin polyurethane sheath with a flexible ring at each end. The inner ring, at the closed end of the condom, serves as the means of insertion and fits over the cervix like a diaphragm.


15 Female condoms made of plastic are also available (Femidom). They offer particularly good protection against infection, as they cover the whole of the vagina and vulva and, being plastic, are less likely to burst. However, many couples find them unaesthetic and they have not achieved widespread popularity.

16 Data on its effectiveness against pregnancy are still limited, although the female condom is slightly less reliable than the diaphragm, male condom, vaginal sponge, and cervical cap

17 advantages It provides better protection than other methods against some pathogens.

18 disadvantages High cost, noisiness during intercourse, cumbersome feel of the device make acceptability a problem for some couples.

19 Diaphragm and Cervical Cap The diaphragm is used with spermicidal cream or jelly and offers a good level of protection from conception. The woman must be fitted with a diaphragm and instructed in its use by trained personnel. The diaphragm should be rechecked for correct size after each childbirth

20 This chemical barrier supplements the mechanical barrier of the diaphragm. The diaphragm is inserted through the vagina and covers the cervix. The last step in insertion is to push the edge of the diaphragm under the symphysis pubis,

21 Diaphragms are inserted immediately prior to intercourse and should be removed no earlier than 6 hours later. The effective use of a diaphragm requires careful teaching and fitting. Female barriers offer protection against ascending pelvic infection but can increase the risk of urinary tract infection and vaginal irritation.

22 It is necessary to leave the diaphragm in place for at least 6 hours after coitus. The diaphragm should then be removed, cleaned with mild soap and water, and allowed to air dry before it is stored in its case.

23 advantages Diaphragms are an excellent contraceptive method for women who are lactating, who cannot or do not wish to use the pill (oral contraceptives), smokers over age 35, avoid the increased risk of PID associated with intrauterine devices.

24 Disadvantages Interferes with the spontaneity of intercourse.. not recommended for women with a history of urinary tract infection, Women with a history of toxic shock syndrome should not use diaphragms

25 The cervical cap is a cup-shaped device, used with spermicidal cream or jelly, that fits snugly over the cervix and is held in place by suction. Effectiveness rates and method of insertion are similar to those for the diaphragm. may be left in place for up to 24 hours,


27 . Advantages, disadvantages, and contraindications are similar to those associated with the diaphragm. The cervical cap may be more difficult to fit because of limited size options. It also tends to be more difficult for women to insert and remove.

28 Lea’s shield is a reusable, silicone rubber device. It is similar to the cervical cap but contains a centrally located valve that permits the passage of cervical secretions and air. It can be used for up to 24 hours with a single application of spermicide.

29  The device is available over the counter in Germany, Austria, and Switzerland for over a decade because one size fits virtually all women.  In the United States, when the manufacturer elects to market it, the device will b available by prescription only

30 Vaginal Sponge The vaginal sponge is again available in the United States. It is a pillow-shaped, soft, absorbent synthetic sponge containing spermicide that is available over the counter. It is made with a concave or cupped area on one side that fits over the cervix. It has a loop for easy removal.

31 The sponge is moistened thoroughly with water before insertion to activate the spermicide and then inserted into the vagina with the cupped side against the cervix It should be left in place for 6 hours following intercourse and may be worn for up to 24 hours, then removed and discarded.

32 Advantages fitting is not required, it may be used for for upto 24 hours, one size fits all, and it acts as both a barrier and a spermicide.

33 Disadvantages cost (12-pack), problems associated with removing it, and irritation or allergic reactions. is less effective than the diaphragm at preventing pregnancy, women using the sponge are more likely than diaphragm users to stop using their method of contraception
