Endocrine disrupting chemicals (EDCs) can interfere with the thyroid hormone (TH) system by e.g. inhibiting the enzyme thyroperoxidase (TPO) and thereby TH production. Low TH levels during development can have adverse effects on the brain, as well as affecting general growth. Hypothyroidism can also affect proliferation of testes cell populations, but in-depth studies on how TH disrupting chemicals can affect testis development are few. Here we show how the TPO inhibitors Amitrole (a pesticide) and methimazole (MMI, a drug) disrupt perinatal testis development in rats, with the most pronounced effect on the germ cell population.
