What Is The Best Non-Hormonal Contraceptive?
Written by: Natasha Evans
Written on: January 15, 2025
Contraception is a deeply personal choice, but we’re now seeing non-hormonal contraceptives increasing in popularity for people who want a long-term solution to contraception that allows the body’s natural hormonal cycles to continue without interference.
There are a number of options out there, with varying degrees of efficacy. Registered Nutritionist and Health Coach, specialising in Fertility, Natasha Evans explores five non-hormonal methods
Copper Intrauterine Device (IUD)
The copper IUD is a popular non-hormonal contraceptive option. It is a small, T-shaped device made of plastic and copper that is inserted into the uterus by your doctor. The copper in the IUD creates a local inflammatory reaction that makes it difficult for sperm to fertilise an egg, and prevents implantation of a fertilised egg.
Some people may experience unpleasant side effects, including heavier periods, cramping, or spotting, especially during the first few months of use. If these don’t ease off and are affecting your quality of life, it’s worth discussing your symptoms with your doctor.
One consideration from a nutritional perspective is that copper can displace zinc in the body, so it’s important to make sure you’re obtaining plenty of zinc in the diet (oysters, shellfish, red meat, seeds) - or consider supplementation with the guidance of a nutritionist.
Barrier methods
Yes we're talking - Condoms, Diaphragms, and Cervical Caps
Barrier methods of contraception, such as condoms (for both men and women), diaphragms, and cervical caps, are designed to physically prevent sperm from reaching the egg. These methods work by creating a physical barrier between sperm and the cervix, preventing fertilisation.
Another benefit is that they offer protection against sexually transmitted infections (STIs), which is a key consideration for many individuals. While barrier methods are highly effective when used correctly, they do have a higher failure rate compared to the copper IUD and hormonal options.
Be wary of some of the chemicals found in conventional condoms and opt for more natural brands if you can. PFAS “forever chemicals” have been found in popular condom brands. Even nitrosamine, a known carcinogen, has been found in condoms. Benzocaine, a local anaesthetic, is added to some condoms to delay ejaculation. Unfortunately, it is a known endocrine disruptor. Spermicides may increase the risk of contracting STIs, whilst glycerin may allow yeast infections to flourish.
Fertility Awareness Methods (FAM)
Fertility Awareness Methods (FAM) involve tracking the body's natural cycles to determine fertile and non-fertile days. Many people are unaware that women are only fertile for about 6 days within each menstrual cycle.
FAM can be done through monitoring basal body temperature, cervical mucus, cervical position and tracking menstrual cycle patterns. FAM requires careful attention and consistency, and it’s most effective when combined with other methods like barrier contraception. Effectiveness really depends on the method used, how many metrics are tracked and adherence, but it’s estimated to be 76-88% effective. It may be less effective for women with irregular cycles and of course does not protect against STIs.
FAM can help a woman become more connected to her body, by learning how to tune into her cycle and her body’s natural rhythms. Some women find this method incredibly empowering - especially as they can take an active role in their fertility and reproductive health.
Does the pull-out method work?
The Pull-out method involves the male partner pulling out prior to ejaculation to prevent sperm from entering the vagina. This tends to be only 78% effective, as pre-ejaculatory fluid does contain sperm so it can be quite hard to get right. The efficacy of this method can be improved by combining it with FAM, so taking more care on fertile days.
Sterilisation
A more permanent form of contraception, involving either tubal ligation for women, or vasectomy for men. Both procedures are highly effective (>99%) at preventing pregnancy.
Sterilisation can be a viable option for individuals who are certain they do not want children in the future as they are difficult to reverse. Sterilisation also does not protect against STIs.
