Male and Female Condoms
What it does: Physically blocks contact between the vagina and the penis, essentially stopping sperm and disease-carrying liquids in their tracks. Along with IUDs, condoms are one of the oldest contraceptive devices known to man. Prior to the 20th century, they were often made from the intestines of sheep or lambs and could be washed and re-used. Today, most condoms are made from latex and need to be thrown out after a single use.
The female condom, on the other hand, is quite new and intimidating to some people. Instead of sliding over the man's penis, the female condom fits inside of you, almost like a pouch or a pocket. Made of polyurethane, it's stronger than latex condoms but also transfers heat better, meaning that both partners can often feel more sensation with the female condom than with the male. You can insert the female condom up to a couple of hours before sex as the two flexible rings, one in the closed end that is held against your cervix and one in the open end that covers part of your outer vaginal lips, keep it securely in place.
Both female condoms and male condoms made from latex or polyurethane protect against STDs, including the smallest viruses like hepatitis B that can sneak through some barriers. Male condoms made from natural lambskin, on the other hand, should only be used for preventing pregnancy. Their pores are too large to block out viruses.
What it doesn't do: It wonÂ’t work if you don't use it. Probably the most common reason for condom failure is couples opting to not use the barrier every time or waiting to put it on until after they've already come into contact with each other's fluids. With typical use, which includes occasional slip-ups like this, the failure rate for condoms alone is between 12 percent and 15 percent. If you follow the instructions to the letter and pair condoms with spermicide, however, that rate can be reduced to as little as 2 percent to 3 percent.
How to get it: Walk down to your local pharmacy, grocery, or big box store. It's that simple. Condoms are available over the counter, and in most places you can waltz right in and pick up a box from the shelf without needing a clerkÂ’s assistance.
Is it reversible? Very much so. The second you take a condom off, you can get pregnant again.
Side effects: None, unless you happen to have a latex allergy. In addition, some people say they don't like the condom because it decreases sensation. If it's not lubricated well enough, the female condom can also make a lot of distracting noise during sex.
Who might benefit most: Anyone who wants to prevent the transmission of STDs. Remember, other birth control methods won't do this. So if you're not absolutely sure about your health and that of your partner (and by this we mean, if you've not both been tested for the full gamut of STDs), using a condom—even if you're already using a different method of birth control—is only common sense.
Who should consider a different method: People with latex allergies used to have few options when it came to condom use. Today, though, polyurethane condoms are widely available. They're every bit as effective as latex, though they are a bit more expensive.
Fertility Awareness
What it does: Turns out, the name is pretty descriptive of what's going on. Women who practice fertility awareness use one (or more) methods of tracking their menstrual cycles, in order to figure out which days they are most likely to be fertile. There are several ways to do this. One of the most famous is the calendar rhythm method: A woman tracks the beginning and end of her period for at least eight months and then uses that information (and a little math) to get an estimate of which days she's most likely ovulating. Other methods may track basal body temperature, which changes minutely in the days before and after ovulation, and cervical mucus, which changes type and thickness with the onset of fertility. Women who combine several of these methods are more likely to be successful at remaining childless.
Once you know which days you're likely to be infertile, you simply save vaginal sex for those days, substituting abstinence, sex with a condom, or your preferred non-vaginal sex act during the rest of the month.
What it doesn't do: Protect you against sexually transmitted diseases. If you decide to use the fertility awareness method it is incredibly important that you and your partner be monogamous. Besides the lack of protection against disease, it seems that committed, monogamous couples are most likely to practice fertility awareness accurately and consistently.
It's also important to note that, unlike most other contraception methods, fertility awareness is quite cheap and can be practiced without buying any specialized tools or paying a monthly fee.
How to get it: Unlike most methods of contraception, fertility awareness requires some serious training if you're going to do it right. You can get the information from a book, but it's often helpful to have a trained counselor who you can contact if you have questions or if you're confused about something that's going on with your body.
Ask your medical professional where you can go to get training in fertility awareness locally. One good source for this is the Roman Catholic Church. Officially, fertility awareness is the church's only approved form of birth control, so Catholic family counselors tend to be pretty well-versed in the methods and potential problems that may arise. They're also likely to offer classes, which you usually can take no matter what religion (or lack thereof) you happen to practice.
Getting training is extremely important as it can mean the difference between a perfect-use failure rate of about 8 percent and a typical or imperfect-use failure rate of anywhere from 20 percent to 40 percent. Bottom line, if you want fertility awareness to work, you'll need to know what you're doing.
Is it reversible? Very much so. In fact, it might even help you get pregnant as, by the time you're ready for that step, you'll have pretty much figured out what your fertile days are and can simply flip your unprotected sex days to fit your new goal.
Side effects: None
Who might benefit most: Couples who have ruled out hormonal and barrier methods for religious, health, or other personal reasons.
Who should consider a different method: Couples who don't want to follow a regimen that requires organizational skills, careful planning, reliable documentation of menstrual patterns, and adherence to strict rules about when sex is OK and when it must be avoided.
Diaphragm & Cervical Cap
What it does: Both diaphragms and cervical caps function as physical barriers, which block sperm from entering the uterus. They also serve as a handy way to hold spermicidal cream or foam against the cervix, providing further protection against sperm. Prior to the 1960s, diaphragms were one of the most popular of all contraceptive devices. Over the years, they've been eclipsed by oral contraceptives and, to a lesser extent, IUDs.
Although it's pretty simple to understand how diaphragms and cervical caps work, using them can be a bit more difficult. Diaphragms are held in place by springs and cervical caps by suction. To get them into position, you need to carefully maneuver them onto your own vagina and set them against your cervix. That takes training. And it takes a diaphragm or cervical cap that has been fitted to your biological proportions. Once you know how to use it, the barriers can be inserted several hours before sex and must be left in for at least six hours afterwards--but should be left in for no longer than 24 hours total.
What it doesn't do: Protect you against all STDs. There is, however, some evidence that it may protect you against some minor STDs, including bacterial vaginosis.
How to get it: You'll definitely need a medical practitioner for this one. Your provider will be able to help you pick the type of diaphragm or cervical cap that is right for you, aid you in finding a size that fits your unique cervical proportions, and show you how to find your cervix with your fingers and put the barrier in place and remove it properly. This training is vital. With perfect use (and particularly in conjunction with condoms) diaphragms and cervical caps have a failure rate of less than 9 percent. Without perfect use, though, that number climbs. Typical use failure rates can range as high as 30 percent.
Is it reversible? Yes, simply have sex without it and fertility returns.
Side effects: Very few. The most concerning issue is a small risk of toxic shock syndrome if the barrier is left in place for longer than 24 hours.
Who might benefit most: Women who aren't comfortable with hormonal methods and who don't mind using a birth control method that requires them to plan ahead each time they intend to have sex.
Who should consider a different method: Women who aren't comfortable being intimately familiar with their insides and with spermicide; one of the complaints about these methods is that they are messy. Another problem is that many women consider the process involved in using a diaphragm or cervical cap to be a huge inconvenience. That tends to lead to non-perfect use and higher failure rates.
