goitrogen

noun

1. Any agent that causes goiter, such as thiouracil.

   “We have previously shown that treating rats with the reversible goitrogen 6-propyl-2-thiouracil (PTU) from birth to Day 25 increases testis size and sperm production in adulthood by up to 80% and 140%, respectively.”

   “These results suggest that excess iodine induces thyroid involution in goitrogen-treated rats at least partially by apoptosis.”
