Birth Control Methods

Birth Control Methods

Though the overwhelming majority of sexually active women and men in America do use birth control, there are no methods that are guaranteed to work 100% of the time. In a recent survey of new mothers in Forsyth County, over 40% said that they had been using some form of birth control when they became pregnant. Many couples who do use birth control may not be using it correctly or may not be using it each time they have sex.

The best way for a sexually active couple to prevent pregnancy is to plan ahead and be prepared!

Types of Birth Control

In choosing a method of contraception, dual protection from the simultaneous risk for HIV and other STDs always should be considered. Although hormonal contraceptives and Intrauterine Devices (IUDs) are highly effective at preventing pregnancy, they do not protect against STDs, including HIV. Consistent and correct use of the male latex condom reduces the risk for HIV infection and other STDs, including chlamydial infection, gonococcal infection, and trichomoniasis.

Non-hormonal Methods

Copper T intrauterine device (IUD) — This IUD is a small device that is shaped in the form of a "T." Your doctor places it inside the uterus to prevent pregnancy. It can stay in your uterus for up to 10 years. Typical use failure rate: 0.8%. Brand name of this device is called "Paraguard."

Hormonal Methods:

Implant — The implant is a single, thin rod that is inserted under the skin of a woman's upper arm by a medical professional. The thin rod contains a progestin that is released into the body over 3 years. Typical use failure rate: 0.01%, and is commonly known as "Nexplanon."

Injection or "shot" — Women get shots of the hormone progestin in the buttocks or arm every three months from their doctor. Typical use failure rate: 4%, and it is most commonly known as "Depo-Provera," or "Depo Shot."

Combined oral contraceptives — Also called "the pill," combined oral contraceptives contain the hormones estrogen and progestin. It is prescribed by a doctor. A pill is taken at the same time each day. If you are older than 35 years and smoke, have a history of blood clots or breast cancer, your doctor may advise you not to take the pill. Typical use failure rate: 7%.

Progestin only pill — Unlike the combined pill, the progestin-only pill (sometimes called the mini-pill) only has one hormone, progestin, instead of both estrogen and progestin. It is prescribed by a doctor. It is taken at the same time each day. It may be a good option for women who can’t take estrogen. Typical use failure rate: 7%.

Levonorgestrel intrauterine system (LNG IUD) — The LNG IUD is a small T-shaped device like the Copper T IUD. It is placed inside the uterus by a doctor. It releases a small amount of progestin each day to keep you from getting pregnant. The LNG IUD stays in your uterus for up to 5 years. Typical use failure rate: 0.1-0.4%. Brand names of these devices are "Mirena, Skyla, and some others."

Patch — This skin patch is worn on the lower abdomen, buttocks, or upper body (but not on the breasts). This method is prescribed by a doctor. It releases hormones progestin and estrogen into the bloodstream. You put on a new patch once a week for three weeks. During the fourth week, you do not wear a patch, so you can have a menstrual period. Typical use failure rate: 7%.

Hormonal vaginal contraceptive ring — The ring releases the hormones progestin and estrogen. You place the ring inside your vagina. You wear the ring for three weeks, take it out for the week you have your period, and then put in a new ring. Typical use failure rate: 7%.

Barrier Methods:

Diaphragm or cervical cap — Each of these barrier methods are placed inside the vagina to cover the cervix to block sperm. The diaphragm is shaped like a shallow cup. The cervical cap is a thimble-shaped cup. Before sexual intercourse, you insert them with spermicide to block or kill sperm. Visit your doctor for a proper fitting because diaphragms and cervical caps come in different sizes. Typical use failure rate for the diaphragm: 17%.

Sponge — The contraceptive sponge contains spermicide and is placed in the vagina where it fits over the cervix. The sponge works for up to 24 hours, and must be left in the vagina for at least 6 hours after the last act of intercourse, at which time it is removed and discarded. Typical use failure rate: 14% for women who have never had a baby and 27% for women who have had a baby.

Male condom — Worn by the man, a male condom keeps sperm from getting into a woman’s body. Latex condoms, the most common type, help prevent pregnancy, and HIV and other STDs, as do the newer synthetic condoms. "Natural" or "lambskin" condoms also help prevent pregnancy, but may not provide protection against STDs, including HIV. Typical use failure rate: 13%.

Condoms can only be used once. You can buy condoms, KY jelly, or water-based lubricants at a drug store. Do not use oil-based lubricants such as massage oils, baby oil, lotions, or petroleum jelly with latex condoms. They will weaken the condom, causing it to tear or break.

Female condom — Worn by the woman, the female condom helps keeps sperm from getting into her body. It is packaged with a lubricant and is available at drug stores. It can be inserted up to eight hours before sexual intercourse. Typical use failure rate: 21%, and also may help prevent STDs.

Spermicides — These products work by killing sperm and come in several forms—foam, gel, cream, film, suppository, or tablet. They are placed in the vagina no more than one hour before intercourse. You have to leave them in place at least six to eight hours after intercourse. You can use a spermicide in addition to a male condom, diaphragm, or cervical cap. They can be purchased at drug stores. Typical use failure rate: 21%.

Fertility Awareness Based Methods

Fertility awareness-based methods — Understanding your monthly fertility pattern can help you plan to get pregnant or avoid getting pregnant. Your fertility pattern is the number of days in the month when you are fertile (able to get pregnant), days when you are infertile, and days when fertility is unlikely, but possible.

• If you have a regular menstrual cycle, you have about nine or more fertile days each month. If you do not want to get pregnant, you do not have sex on the days you are fertile, or you use a barrier method of birth control on those days.
• Failure rates vary across these methods, range of typical use failure rates: 2-23%.
