If you’ve watched a zombie movie with your friends, you’ve probably talked about what kinds of weapons you’d be packing in case of a zombie apocalypse. The Centers for Disease Control and Prevention even has a list of supplies you’ll need for a zombie preparedness kit, which includes smart choices like water, duct tape, and bleach. (I would add toilet paper to that list. How you’ll miss it when you’re on the run!) But how many of you have discussed birth control?

You’ve probably picked out which weapons to use during the zombie apocalypse. But have you chosen a birth control method?

Even if your greatest dream is to have a baby, you must admit that the zombie apocalypse is the worst time to be pregnant, give birth, and raise a child. Fleeing and hand-to-hand combat can be a drag while pregnant, and childbirth can kill you, especially without access to trained personnel or hygienic supplies. And if you do manage to birth a baby into this cruel new world, diapers can distract from more pressing duties, and the infant’s cries can attract undead attention.

When you’re in hardcore fight-or-flight mode, taking a pill at the same time every day might be difficult, and besides, a supply of pills can take up valuable backpack real estate. Plus, even if you find an abandoned pharmacy to raid, birth control pills and condoms come with expiration dates and can be affected by high temperatures. The same goes for contraceptive patches and rings. For these reasons, you need a contraceptive method that’s well suited to the zombie apocalypse. Besides abstinence, what are your options?

Let’s Talk Contraception: Is Spermicide Effective?

Posted on by

According to the Guttmacher Institute, 0.5 percent of all contraceptive users surveyed in 2010 relied on spermicides as their contraceptive. Although not used often, they are a part of the contraceptive choices sexually active people have to prevent pregnancy. How effective are they, however?

The only available spermicide in the United States is nonoxynol-9. It is available in many products, such as a foam, cream, gel, suppository, or dissolvable film. Nonoxynol-9 is also the main ingredient in the Today contraceptive sponge.

Some spermicides increase risk of HIV transmission.

As a contraceptive by itself, it is not very effective at preventing pregnancy. Throughout the course of one year, and with proper use at every sexual act, 18 women out of 100 will become pregnant using spermicides alone. If used less than perfectly, that number rises to 29 out of every 100 women becoming pregnant. When used with a condom, however, the effectiveness is greatly increased. And spermicides are regularly used in combination with diaphragms and cervical caps. Continue reading →

Over 90 Percent of What Planned Parenthood Does, Part 15: Fertility Awareness Education

Posted on by

Welcome to the latest installment of “Over 90 Percent of What Planned Parenthood Does,” a series on Planned Parenthood Advocates of Arizona’s blog that highlights Planned Parenthood’s diverse array of services — the ones Jon Kyl never knew about.

Fertility awareness is not the same as the rhythm method.

Let’s start there.

It’s a common misconception that is, at best, a massive oversimplification that misconstrues the concept and may lead people to dismiss or deride fertility awareness out of hand. In reality, a lot of people could benefit from a more thorough understanding of fertility, as many sexually active couples spend a lot of their lives trying to control it — whether to avoid or achieve pregnancy. Planned Parenthood health centers provide education in fertility awareness-based methods (FAMs) for a variety of purposes.

If fertility awareness is not just the rhythm method, what is fertility awareness?

For someone having menstrual cycles, fertility awareness involves monitoring cycle signs and symptoms — predominantly cervical fluid and basal body temperature, though these are often supported or “cross referenced” by tracking other signs as well — in order to determine when a person is approaching ovulation and/or to confirm when ovulation has already taken place.

How does that even work?

Fertility awareness-based methods rely on a few underlying assumptions about fertility and the likelihood of conception:

  1. For pregnancy to happen, there must be both sperm and an ovum (egg) present.
  2. Ovulation — the release of an egg from the ovary into the fallopian tube — occurs once per menstrual cycle.
  3. Sperm can survive inside someone with a uterus for approximately five to six days. (Note: The actual number a given person or couple will want to use for this assumption can vary a bit depending on whether their main goal is to achieve or avoid pregnancy.)
  4. The ovum itself is viable in the fallopian tube for approximately one to two days. After that, it begins to disintegrate, and fertilization is not possible during that cycle. (Again, different couples may use different assumptions depending on their goals.) Continue reading →
