What is Natural Fertility Awareness?
Natural Fertility Awareness (NFA) is the understanding of the natural signs of a woman’s fertility throughout her menstrual cycle. Every woman’s body communicates changes that reveal the different phases of her cycle, including her naturally fertile and infertile times.
By observing and recording these natural signs—such as changes in cervical mucus, body temperature patterns, and hormonal changes—women can develop a deeper understanding of their fertility, reproductive health, and the unique rhythms of the female body.
Natural Fertility Awareness forms the foundation of Natural Family Planning (NFP). Couples who understand and apply this knowledge within marriage can use it to make informed decisions about family planning in a way that respects the natural rhythms of the body.
Natural Fertility Awareness is based on scientific observation and can be used throughout the different stages of a woman’s life, including adolescence, marriage, after the birth of a child, breastfeeding, and perimenopause.
For many women, learning to track their cycle provides valuable insight into their overall health by helping them recognise patterns and changes in their body. This knowledge can support conversations with healthcare professionals and help women care for their reproductive wellbeing.
Natural Fertility Awareness in Marriage
Within marriage, the knowledge gained through Natural Fertility Awareness can be used in Natural Family Planning (NFP). NFP is an approach to family planning that works with the natural rhythms of fertility rather than suppressing or altering them. It enables couples to make decisions together while respecting the dignity of the marital act.
Â
Natural Family Planning can support couples throughout the different stages of married life, including:
when seeking to conceive
after the birth of a child
during breastfeeding
when discerning whether to space pregnancies
Like all important decisions in marriage, the use of NFP involves prayer, communication, and discernment. When used to postpone pregnancy, the Catholic Church teaches that this should be for serious and just reasons. NFP respects fertility as a gift and remains open to the dignity of every human life.
The Catholic Church recognises fertility as a gift and teaches that marriage is both unitive and life-giving. This understanding is beautifully expressed through the Theology of the Body, developed by St John Paul II, which teaches that the human body reveals God’s plan for love and relationships. Fertility is not simply a biological function but an integral part of the person and a gift to be understood and respected. Through this lens, husband and wife are called to receive one another fully and remain open to the gift of life.
“(Natural Fertility Awareness) methods respect the bodies of the spouses, encourage tenderness between them, and favour the education of an authentic freedom.”
— Catechism of the Catholic Church, 2370

Provides detailed cycle information that can support reproductive and gynaecological health.
Often used alongside restorative reproductive medicine.
Marquette Method
Combines fertility observations with hormone monitoring using a fertility monitor.
Incorporates objective hormonal data to help identify fertile and infertile phases.
Uses a technology-assisted approach, particularly during breastfeeding and the postpartum period.
Sympto-thermal Method
Combines fertility observations with hormone monitoring using a fertility monitor.
Incorporates objective hormonal data to help identify fertile and infertile phases.
Uses a technology-assisted approach, particularly during breastfeeding and the postpartum period.
Reproductive Health Support
Natural Fertility Awareness can provide valuable insights into reproductive and hormonal health. Information gathered through fertility charting may assist healthcare professionals in identifying and addressing underlying reproductive health concerns. The following approaches integrate fertility awareness with medical care to support women’s health and fertility.
NaPro Life Centre
NaPro Life Centre provides care for couples experiencing infertility, as well as a wide range of women’s and men’s health conditions.
They have a holistic and thorough approach based on NaProTechnology (Natural Procreative Technology), a branch of Restorative Reproductive Medicine that focuses on identifying and treating the underlying causes of reproductive and hormonal health issues. This includes conditions such as PCOS, endometriosis, recurrent miscarriage, low sperm counts, low testosterone, PMS, and irregular cycles.
Treatment is supported by the Creighton Model FertilityCare System, a standardised fertility awareness method that tracks key fertility biomarkers. This detailed cycle information helps doctors identify underlying health issues and develop personalised treatment plans for each patient or couple.
Rather than suppressing or bypassing fertility, NaProTechnology seeks to restore normal reproductive function, improve overall cycle health, and support couples in achieving pregnancy naturally.
Fertility Education & Medical Management (FEMM)
FEMM is a women’s health programme that combines fertility awareness education with reproductive healthcare. It teaches women to observe and chart hormonal biomarkers throughout their menstrual cycle, helping them better understand their fertility, hormonal health, and overall wellbeing.
Â
Using information gathered through fertility charting, FEMM-trained healthcare professionals can assess reproductive and hormonal health and investigate potential underlying concerns. FEMM is often used to support women experiencing irregular cycles, hormonal imbalances, polycystic ovarian syndrome (PCOS), reproductive health concerns, and other conditions that may affect fertility and wellbeing. Through education, charting, and medical support, FEMM seeks to empower women with knowledge about their bodies and promote lifelong reproductive health.

Frequently Asked Questions
1. Understanding Natural Fertility Awareness
What is Natural Fertility Awareness?
Natural Fertility Awareness is the practice of observing and understanding the natural signs of fertility throughout a woman’s menstrual cycle. By recognising these signs, women and couples can better understand their fertility, reproductive health, and the natural rhythms of the body.
Is Natural Fertility Awareness the same as Natural Family Planning?
Natural Fertility Awareness is the foundation of Natural Family Planning. Natural Fertility Awareness refers to learning and observing the signs of fertility, while Natural Family Planning is the use of this knowledge within marriage to make decisions about achieving or spacing pregnancies.
Is Natural Fertility Awareness only for married couples?
No. Natural Fertility Awareness can benefit women throughout different stages of life, including learning about their cycle, understanding their health, and recognising changes in their body. Within marriage, couples can use this knowledge together to understand fertility and make decisions about family life.
2. How Natural Fertility Awareness is Used
Can Natural Fertility Awareness be used to achieve pregnancy?
Yes. Understanding the signs of fertility can help couples identify the times when conception is more likely and support them when trying to conceive.
Can Natural Fertility Awareness be used to space pregnancies?
Yes. Married couples may use Natural Fertility Awareness and Natural Family Planning to space pregnancies when there are serious and just reasons, through prayerful discernment, communication, and consideration of their family circumstances.Â
Does Natural Fertility Awareness work if a woman has irregular cycles?
Yes. Natural Fertility Awareness methods can be used during different stages of life and can be adapted for situations such as irregular cycles, breastfeeding, postpartum, and perimenopause. Working with a trained educator can help women understand their unique cycle patterns.Â
3. Methods and Learning
Are all Natural Fertility Awareness methods the same?
No. Different methods observe different signs of fertility and use different approaches, such as cervical mucus, temperature, hormonal monitoring, or a combination of indicators. Couples can explore the method that best suits their circumstances.Â
What are the different Natural Fertility Awareness methods?
There are several Natural Fertility Awareness methods, each of which observes different signs of fertility. You can learn more about the Billings Ovulation Method, Creighton Model FertilityCare System, Marquette Method, and Sympto-thermal Method in the Natural Fertility Awareness Methods section of this website.
How do I learn a Natural Fertility Awareness method?
Each method has trained educators who teach couples how to observe, record, and interpret fertility signs. Learning with a qualified educator helps couples use the method confidently and correctly. You can find a list of recommended educators and practitioners on this website.
Can Natural Fertility Awareness help with reproductive health concerns?
Yes. Fertility charting can provide valuable information about a woman’s cycle and may assist healthcare professionals in identifying underlying reproductive or hormonal health concerns.
4. Catholic Teaching on Fertility & Family Life
What does the Catholic Church teach about fertility and contraception?
The Catholic Church teaches that fertility is a gift and an important part of marriage. Marriage is both a loving union between husband and wife and is naturally open to the gift of life. The Church encourages couples to approach family planning with prayer, wisdom, and openness to God’s plan.
Why does the Catholic Church encourage Natural Family Planning?
The Church encourages Natural Family Planning because it respects the dignity of the human person, the beauty of marital love, and the natural gift of fertility. Natural Family Planning allows couples to understand their fertility and make decisions about family life together while respecting the meaning of the marital act.
Why does the Catholic Church not support contraception?
The Catholic Church teaches that contraception separates the unitive and life-giving meanings of the marital act by intentionally preventing its natural openness to life. Instead, the Church encourages couples to respect the natural cycles of fertility through methods such as Natural Family Planning, which work with the body rather than against it.Â
Does using Natural Family Planning mean couples must always try to have as many children as possible?
No. The Church recognises that couples may prayerfully discern when to welcome a child and when there may be serious and just reasons to space pregnancies. This discernment involves love, responsibility, communication, and consideration of the wellbeing of the family.
How can Natural Family Planning strengthen a marriage?
Natural Family Planning invites couples to communicate, make decisions together, and grow in understanding of one another. It can encourage mutual respect, patience, generosity, and a deeper appreciation of the gift of fertility within marriage.
What does the Catholic Church teach about In Vitro Fertilisation (IVF)?
The Catholic Church recognises the deep desire of couples to have children and compassionately supports those experiencing infertility. It teaches that new life is a gift and should come about within the loving union of husband and wife. Because IVF creates life outside of the marital act and may involve the freezing, selection, or loss of embryos, the Church does not see it as consistent with the dignity of marriage and human life. Instead, it encourages approaches that seek to understand and treat the underlying causes of infertility while respecting the natural processes of the body.
What alternatives to In Vitro Fertilisation are consistent with the Catholic Church's teaching?
The Catholic Church encourages approaches that seek to understand and treat the underlying causes of infertility while respecting the dignity of marriage and human life. Restorative Reproductive Medicine, including NaProTechnology and Fertility Education and Medical Management (FEMM), works alongside Natural Fertility Awareness to investigate and treat reproductive health conditions that may affect fertility.
You can learn more about these approaches in the Reproductive Health Support section of this website, including information about NaPro Life Centre, Fertility Education and Medical Management (FEMM), and trained healthcare professionals who provide fertility-focused medical care.
