The Truth About Fertility Awareness and Withdrawal: Facts, Myths, and Real-Life Effectiveness

I see many women who are seeking gentle, body-aware approaches to contraception and fertility. Recently, a client came to me deeply concerned after being told that using Fertility Awareness Methods (FAM)—specifically Basal Body Temperature (BBT) charting combined with withdrawal—wasn’t effective, and that she might struggle to conceive in the future as she hasn't already conceived in the past few years using this method. This is not only discouraging, but also inaccurate based on both research and traditional wisdom.


Let’s look at the facts:


- **FAM (including BBT) is a well-established, evidence-based approach.** With perfect use, modern FAMs can be over 95% effective—meaning fewer than 5 out of 100 women per year will become pregnant. Typical use (which includes human error and life’s unpredictability) sees effectiveness around 76–88%, but this can be improved with education and support.

- **Withdrawal, when practiced correctly, is about 96% effective, but with typical use, the pregnancy rate is around 22 per 100 women per year.** When you combine FAM with withdrawal or condoms during fertile days, you are layering protection, which increases overall effectiveness.

- **There is no evidence that using FAM or withdrawal harms future fertility.** In fact, tracking your cycle can help you understand your body’s rhythms and may support conception when you’re ready.


Why is this method underreported?

Many women quietly use FAM and withdrawal or condoms, but don’t always disclose this to their healthcare providers—often because of dismissive comments or misinformation from friends or professionals. This leads to underreporting, even though these methods are widely practiced and deeply rooted in women’s health traditions.


Traditional roots: 

Fertility awareness is not new. Ancient cultures, including those referenced in the Talmud, recognized patterns of fertility. The first scientific record of FAM dates to the early 20th century, with the rhythm method described by Dr. Ogino and Dr. Knaus in the 1920s and 1930s. These early methods have evolved into the more accurate, symptom-based approaches we use today.


A naturopathic perspective:

As a naturopath, I value approaches that honour the body’s natural cycles and empower women with knowledge. FAM is not only about contraception—it’s about understanding your hormones, your energy, and your connection to nature. When we combine this wisdom with evidence-based practice, women can make informed, confident decisions about their reproductive health.

If you’re considering FAM, BBT, or withdrawal, seek out a trained educator and don’t let myths or negative comments undermine your confidence. These methods are valid, effective, and have stood the test of both tradition and science.

I have a YouTube video explaining the basics here:
