[The participation of the milk prolactin of lactating rats in the formation of the monoaminergic mechanism regulating the reproductive functions of their progeny].

Puberty was found to be delayed in female rats who had not obtained necessary amount of prolactin with the mother's milk. These rats developed hyperprolactinemia in reproductive age associated with a decrease in the hypothalamus' dopaminergic tonus as well as a decrease of the sexual steroids level. These rats develop most often disorders of estrous cycle and reproductive function.
