“Detox” is a popular health buzzword these days, and for good reason. When it comes to pre-conception work, there is significant evidence to support its use in the months prior to planning to conceive.

A 2005 Environmental Working Group study found an average of 200 industrial chemicals and pollutants in umbilical cord blood. Lead, cadmium and mercury were measured in placental tissue, umbilical cord and maternal blood samples. Decreasing the toxin burden of both parents will not only improve egg and sperm quality, but also decrease the maternal toxin burden passed on to child in utero via the placenta and while breastfeeding.

In my clinical practice, I typically recommend a three-month preconception detox for both partners, to have the biggest impact on egg and sperm quality, and to release stored toxins prior to conception. This plan typically includes:

    • Decreasing the amount of toxins that are entering the body – particularly in the food supply, as well as water and air and home environment – using EWG’s dirty dozen list to guide organic produce purchasing decisions is a great place to start
    • Supporting the liver in the detoxification process, with both nutrients and herbal support, along with a whole-foods diet – Milk Thistle is a herbal medicine I often prescribe for liver support
    • Supporting the emunctories (our elimination organs, including the GI tract, lungs and skin) in ridding our bodies of toxins – I often start with probiotics and foods/fibre that will promote regular bowel movements

Fertility involves a complex series of factors that empower or disempower your body, and your partner’s body, to reproduce another human being. Any strategy you can use to support your bodies to be at their best is worth pursuing, and detox has the happy side effect of supporting your bodies in numerous other ways to be healthy parents during and after pregnancy as well!

I hope you have found this helpful, and do let me know if you have any questions!
