The podcast episodes discuss how endocrine-disrupting chemicals, particularly phthalates and bisphenols, are impacting reproductive health and development, leading to declining fertility rates and potential economic consequences.

The episodes highlight the 'under-masculinization' of males and the need for safer alternatives to protect reproductive health, as these chemicals can interfere with hormones like testosterone.

The episodes provide insights from the research of Dr. Shanna Swan, who has extensively studied the impact of these chemicals on fertility and gender development.
