What’s more, the female offspring born of mothers who are exposed to atrazine suffer from retarded mammary gland development [7, 8]. Female rat pups exposed prenatally (while in the womb) have significantly delayed and underdeveloped mammary glands (breast).
Even though they were only exposed in the womb, not after birth or as adults, these prenatally exposed animals do not recover as adults . When these rats reproduce they are unable to suckle (feed) their young properly. As a result, the second generation (grandchildren of the originally exposed mothers) show low grow rates as a result of decreased nutrition.
