Some facts Some facts about common about common

forms of forms of contraception.....contraception.....

Depo-Provera

Depo-Provera is a synthetic hormone that is injected into the buttock or arm every 12 weeks (3 Months). The hormone keeps the ovaries from releasing eggs. It also thickens the cervical mucus. This keeps sperm from joining with an egg.

Typical failurerate = 3%

The Intrauterine Device (IUD)

IUDs are small devices made of plastic that contain copper or a natural hormone. IUDs usually work by preventing fertilization of the egg. They also may work by affecting the way sperm or eggs move or by affecting the lining of the uterus in ways that prevent implantation.

Typical failurerate = 0.1-0.8%

The PillCombined pills keep the ovaries from

releasing eggs (ovulation). Mini-pills can also prevent ovulation. But they work mainly by thickening the cervical mucus. This prevents the sperm from joining with the egg. Mini-pills may also prevent fertilized eggs from implanting in the uterus.

Typical failurerate = 8%

Birth Control PatchBirth Control Patch

Typical failurerate = 1.3%

The contraceptive patch contains hormones similar to those in birth control pills. You must change your patch once a week for three consecutive weeks. You do not need to apply a patch during the fourth week.

The RingThe vaginal contraceptive ring consists of a

flexible, transparent, colorless vaginal ring about 2.1 inches in diameter containing the hormones etonogestrel and ethinyl estradiol, which are similar to the active ingredients in some oral contraceptives. After the ring is inserted, it releases a continuous low dose of the hormones. A new ring is used each month for continuous contraception A woman inserts the ring herself, and it should remain in the vagina for three weeks. She then removes the ring for one week during which she will have her menstrual period.

The Condom

A barrier method Has added protection if used with

spermicide use water-based lubricants only Latex May Break especially with

age.. Also provides protection against

STD’s

Typical failurerate = 15%

DiaphramDiaphragms and cervical caps are soft rubber barriers

that are intended to fit securely over the cervix. Both are used with a spermicide cream or jelly. Each blocks the entrance to the uterus, and the jelly or cream immobilizes sperm, preventing it from joining the egg.

Emergency Contraception Post-Coital ContraceptivesPost-Coital Contraceptives

– morning after pill (e.g., Preven & Plan B)- Emergency contraception (EC) consists of the same hormones

found in ordinary birth control pills.

– within 72 hours of unprotected intercourse– Side-effects: nausea, vomiting, and cramping– 20-25% become pregnant

Like regular contraceptive pills, Plan B generally acts by preventing ovulation or fertilization, according to the F.D.A. Plan B may in rare circumstances prevent a fertilized egg from becoming implanted, something abortion opponents decry. But regular oral contraceptives do that, too.

Emergency Contraception The U.S. Food and Drug Administration

(FDA) announced on August 24, 2006 the approval of Plan B as an over-the-counter (OTC) option for women aged 18 and older. Plan B will remain available as a prescription-only product for women age 17 and under.

As much as 43% of the decline in abortion between 1994 and 2000 can be attributed to the use of emergency contraception.

Surgical Sterilization For Males a Vasectomy cuts and ties the vas

deferens to prevent sperm from entering the reproductive pathway.

For Females, a Tubal Ligation, cuts and ties the fallopian tube to prevent the egg from reaching the uterus.

Both procedures may be reversed with limited success and is very costly! Even these procedures are not considered 100% effective since there have been pregnancies in extremely small number of cases
