To protect your hormonal balance and optimize your fertility, limit your exposure to scented products (cosmetics, candles) and prioritize labels marked "fragrance-free" rather than "unscented," as the latter often conceals chemical masking agents.

Andrew Huberman’s claim regarding the presence of hormone-disrupting ingredients in scented products is scientifically grounded. Phthalates and other synthetic compounds, often hidden under the generic term "fragrance" in cosmetics, are known to interfere with the endocrine system. A comprehensive review of the scientific literature published in MDPI (combining toxicological and observational studies) establishes a clear link between repeated exposure to these substances and disruptions in reproductive health, particularly concerning egg quality. Furthermore, in its official guidelines (expert advice), the U.S. Environmental Protection Agency (EPA) confirms that products labeled "unscented" frequently contain chemical masking agents to neutralize odors, unlike products that are truly "fragrance-free." Although the impact of a single product remains minimal, an observational study from Harvard University shows that the daily accumulation of these environmental micro-exposures can affect hormonal well-being and the chances of conception. Reducing these exposures therefore constitutes a rational precautionary strategy that is very simple to integrate into one’s daily routine.
