Working with IVF

If your path to pregnancy includes fertility treatments such as intrauterine insemination (IUI) or in vitro fertilisation (IVF), you should know that these do not bypass the need for improving egg, sperm and uterine health with dietary and lifestyle changes or other natural healing modalities. “Natural” & “Fertility treatments” are not mutually exclusive and have the potential to support each other

The purpose of this article is to explain some of the emerging science around supporting fertility through nutrition and lifestyle changes. It is not to give a comprehensive education or individualised support. We recommend working closely with a functional medicine practitioner to give you bio-individual guidance (book a discovery call with us here).

Assisted reproductive technologies (ARTs) such as IVF have fundamentally contributed to reproductive health over the last few decades, and the science continues to evolve. IVF and IUI work by overcoming some of the more physical obstructions to conception such as

  • Low sperm motility

  • Excess endometrial tissue (from endometriosis)

  • Blockages in the uterus or uterine tubes

  • Lack of cervical mucous or inability of sperm to pass through the cervix

  • Antibody issues that may damage egg or sperm

However, “by and large, ARTs do not address the fundamental issue of reproductive aging in women: age-related decline in egg quality.” (1)

As we have explained in more detail in our article on the science of egg health, aging of the egg may include other factors besides the age of the woman. The role of mitochondria is an essential component of egg (and sperm) health that may be contributing to chromosomal abnormalities or fertility challenges.

A growing body of literature shows that both egg and sperm health can be improved through dietary changes, supplementation and avoiding exposure to toxins, as well as through other technologies such as mitochondrial transfer (2). It is interesting to note that these studies are largely funded and conducted not by natural practitioners but by conventional fertility clinics looking for ways to improve outcomes of IVF.

The 4 months leading up to ovulation are critical for egg maturation and health. Sperm maturation takes slightly shorter at approximately 72 days. Of course, while we recommend that dietary and lifestyle changes are more long term than this, these months do provide us a critical window of opportunity for improving chances of conception. Whatever treatments your path to pregnancy may include, maximising optimal nutrients and limiting exposure to harmful chemicals during this time has been shown to improve chances of conception and positive pregnancy outcomes.

In our practice we work with various nutritional and lifestyle indicators that may support your fertility journey. These include:

  • Exposure to BPA, Phthalates & other chemicals (3,4,5,6)

  • Vitamin D (7,8)

  • Folate versus folic acid, genetic variation (MTHFR) (9)

  • Vitamin B12 (10,11)

  • Antioxidants such as COQ10 (12,13)

  • Magnesium (14)

  • Myoinositol (15,16)

  • DHEA (17,18)

  • Other Antioxidants: vitaminE, vitamin C, selenium and zinc (19, 20)

BPA and phthalates compromise egg quality by interfering with meiosis and causing chromosomal abnormalities in eggs. They are also endocrine disrupters and as such interfere with the carefully orchestrated hormones which coordinate the reproductive system.

Folate and vitamin B12 (methylcobalamin) in their bioavailable forms, not only prevent birth defects but also contribute to restoring ovulation and improving egg quality. They play a significant role in creating new DNA, proteins and play a critical role in detoxification. Vitamin B12 has been shown to contribute to better embryo quality.

CoEnzyme Q10 (and other antioxidants), is an essential raw ingredient for energy production required for meiosis and ovulation. It preserves egg quality and has been shown to prevent decline in egg quality and even the potential to reverse the aging process.

Zinc and selenium are important for thyroid function and zinc deficiency interferes with completion of meiosis, a critical pre-ovulatory step.

Energy production, vital for the energy required for meiosis and ovulation, is a magnesium intensive process, and improves pre-implantation blastocyst development. Magnesium also improves motility of sperm.

Myo-inositol is effective in normalizing ovarian function, improving oocyte and embryo quality in PCOS

In our practice we work with high quality, practitioner grade nutritional supplements when appropriate. This means that ideally pathology testing has been done and measured against functional medicine optimal standards, and close attention has been paid to your symptomatology and medical history. Supplements are just that; they supplement a long term nutrient dense diet and a lifestyle that does not include over-exposure to endocrine disrupting chemicals, antibiotics and stress. We work with all of these factors; meeting you where you are at and taking small steps that will lead to big positive changes for you and your family’s long term health.
