Do fragrances affect hormones?

Fragrances can indeed affect hormones due to the presence of chemicals known as xenoestrogens. These chemicals, found in many personal care products like perfumes, can act like weak hormones and influence hormone receptors in the body over time. For example, a case study mentioned on the podcast involved a boy who developed significant gynecomastia (breast tissue development) which subsided after discontinuing certain personal care products that contained such chemicals 1. The hosts of the podcast emphasize that although isolated exposure to these chemicals may be deemed safe, the cumulative effect of multiple exposures can be of concern 2.
