Heavy metals: the invisible saboteurs of your fertility
Heavy metals and fertility: mercury, cadmium, lead, and aluminium disrupt ovulation, degrade egg quality, and can be passed on to the baby. An HTMA test allows you to assess your toxic load before conception in order to protect your natural fertility. Credit: Eurofins Biomnis
You can't see them, you can't feel them, but heavy metals (mercury, lead, aluminium, cadmium) accumulate insidiously in your body through food, water, air, and cosmetics.
The physiological impact: Heavy metals are major endocrine disruptors. They accumulate in your tissues and organs (ovaries, thyroid, adrenal glands) and interfere with normal hormonal function. Cadmium, for example, mimics oestrogens and creates an artificial oestrogen dominance. Mercury impairs egg quality and disrupts embryo implantation. These toxins also generate oxidative stress that damages the DNA of reproductive cells. A crucial point: these heavy metals can be passed on to the baby during pregnancy and breastfeeding. This is why it is essential to prepare the ground and assess your toxic load before conception, in order to protect your health and that of your future child.
What you can explore:
- An HTMA test (hair tissue mineral analysis) that reveals chronic exposure to heavy metals and mineral imbalances
- Limit large fish (tuna, swordfish) and favour small fish (sardines, mackerel)
- Support your natural detoxification pathways (liver, intestines, kidneys)

Chronic inflammation and oxidative stress: the invisible fire
You may have heard of acute inflammation (a sprain, an infection). But chronic inflammation is silent and insidious.
The physiological impact: Chronic low-grade inflammation creates a hostile environment for conception. Pro-inflammatory cytokines (IL-6, TNF-alpha) disrupt follicle maturation, degrade egg quality, and make the endometrium less receptive to implantation. Oxidative stress (excess free radicals) damages the DNA of eggs, reduces ovarian reserve, and can cause early miscarriages. This oxidative stress is amplified by smoking, alcohol, pollution, a lack of antioxidants, and blood sugar imbalances.
What you can explore:
- Is your diet rich in antioxidants (berries, colourful vegetables)?
- Reduce ultra-processed foods, refined sugar, and trans fats
- Supplementation with omega-3, vitamin E, CoQ10, glutathione (with professional guidance)
- Measure your hs-CRP; the target is a result below 1
Chronic stress: when your body is in survival mode
Stress is not "just in your head". It is a physiological reality that disrupts your hormonal balance from top to bottom. And bear in mind: physiological stress is not limited to anxiety or emotions. It can also be caused by chronic sleep deprivation, nutritional deficiencies, or persistent inflammation.
The physiological impact : Chronic stress permanently activates your hypothalamic-pituitary-adrenal (HPA) axis. The result: your adrenal glands produce cortisol continuously. Cortisol inhibits GnRH (the hormone that triggers the entire ovulation cascade), which blocks or delays ovulation. Furthermore, progesterone and cortisol share the same precursor (pregnenolone): when your body has to choose between managing stress and ovulating, it chooses survival (cortisol) at the expense of fertility (progesterone).
What you can explore:
- Quality of your sleep: do you wake up several times a night, and how do you feel in the morning after a night's sleep?
- Your nutritional intake: deficiencies in magnesium, B vitamins, iron?
- Nervous system regulation techniques: cardiac coherence, meditation, yoga
- Adaptogens (rhodiola, ashwagandha) to support the adrenal glands (with professional guidance)
