Fertility Awareness 101

You may have heard of Fertility Awareness at some point (sometimes referred to as Natural Family Planning), and wondered – what is Fertility Awareness? how exactly does it work? which method should I use? Is it trustworthy? Our mission is to help you understand it, so that you can make an informed decision about whether it is right for you.

You may have heard of Fertility Awareness at some point (sometimes referred to as Natural Family Planning), and wondered – what is Fertility Awareness? how exactly does it work? which method should I use? Is it trustworthy? Our mission is to help you understand it, so that you can make an informed decision about whether it is right for you.

Fertility Awareness can be summarised as:

‘Being aware of your own signs of fertility, so that you know when your fertility starts and ends each cycle’

Being aware of your own signs of fertility throughout your life can tell you:

  • The start and end of your fertility each cycle
  • Whether you are ovulating or not, and when
  • When to expect your next period
  • Whether your fertility is returning after stopping hormonal birth control, or breastfeeding
  • If you are pregnant (without the need for multiple pregnancy tests)
  • If your menstrual cycle is changing due to peri-menopause
  • What hormones may be impacting on your fertility and health

Fertility Awareness is a body awareness skill that can support you from puberty, right up until menopause. Natural Fertility NZ (NFNZ) trains Educators to teach Fertility Awareness to individuals and couples.

Practicing Fertility Awareness involves learning to recognise and record your signs of fertility on a chart, and then interpreting that information to work out where you are in your cycle. Your motivation, and goals will change throughout your reproductive life, whether you are wanting to conceive, avoid conception, or just track your fertility – therefore you need a trustworthy method of Fertility Awareness that can meet you where you are at, and be modified for your different life stages.

NFNZ teaches the Sympto-thermal Method (STM) for both avoiding conception, and to those trying to conceive. The method incorporates cervical mucus, vaginal sensation, and basal body temperature. We also teach you how to check your cervix (especially helpful if you are not noticing much cervical mucus) – but this is entirely optional. The Sympto-thermal Method as taught by NFNZ also uses some key indicators to ‘double check’ – this provides an extra layer of assurance when using the method to avoid pregnancy.

We also teach the Lactational Amennorhoa Method and Breastfeeding Charting to those who have just given birth, and are breastfeeding.

The Sympto-thermal Method is supported by international research and proven to be at least 98% effective by the World Health Organisation, as long as it is taught by an Accredited Fertility Educator, and practised consistently and correctly. The latest research from Germany shows an improved efficacy of 99.4% (Petra Frank-Hermann 2007).

In 2020, the Ministry of Health (now Health NZ), published their New Zealand Aotearoa’s guidance on contraception, which was an in-depth review on the current contraceptive options available and in use in New Zealand, along with recommendations. The main takeaways for the Sympto-thermal Method (STM) were:

The STM is much more effective at preventing a pregnancy than other forms of Fertility Awareness. With correct and consistent use, there is less than 1 pregnancy for every 100 individuals using the method over the course of a year. Combining fertility signs (like cervical mucus, sensation, and basal body temperature) is much more effective than relying on only one sign of fertility. It is important to learn how to use the STM from a trained Fertility Educator for the best effectiveness rate

There are many reasons why Fertility Awareness may be the right choice for you, some of them are:

  • You want to use a method that aligns with your beliefs or faith
  • You can not use hormonal contraception due to health reasons
  • You have stopped using hormonal contraception, and you want to track your return to fertility in preparation for getting pregnant
  • You are wanting to get pregnant – Fertility Awareness can shorten the time to conception
  • You want to understand your body better

“There are many misconceptions about Fertility Awareness based methods, so it is an exciting opportunity to separate fact from fiction, and provide information that individuals and couples can trust when it comes to making decisions about contraception”, says Lena Wells, NFNZ’s President.

NFNZ Fertility Educators teach the Sympto-thermal Method for avoiding conception, which is over 98% effective when taught by an Accredited Educator. Endorsed by Health NZ and the World Health Organisation, this method provides a viable alternative to those who either can’t or do not want to use hormonal contraception.

The knowledge gained through learning the Sympto-thermal Method can also be used to help identify any hormonal imbalances, and shorten the time to conception for those trying to conceive. There are also options for those who are breastfeeding, but as mentioned above, it is vital that these are practiced alongside the support of an Accredited Educator to avoid any unplanned pregnancies. 

“Everyone’s fertility is unique, which means there is no ‘one size fits all’ solution. NFNZ Educators are well equipped to work out whether one of our evidence based methods will work for someone, so all enquiries are welcome. Learning about Fertility Awareness is an empowering process, and we look forward to supporting you on your fertility journey”
