[Hyperprolactinemia and disorders of the menstrual cycle].

Introduction: The authors presented physiological conditions associated with increased prolactin values (sleep, stress, hypoglycemia, nipples stimulation, pregnancy and lactation) as well as the causes of pathological hyperprolactinemia.

Material And Methods: The results of radioimmunoassay study have been analyzed in concern to the values of follicle-stimulating hormone (FSH), luteinizing hormone (LH) and prolactin (PRL) obtained from the serum of 100 women with increased PRL levels. The "HOECHT" sets were used for the analysis, whereas the values up to 20.

[Prolactin and the menstrual cycle].

In order to estimate serum prolactin levels during particular menstrual cycle phases, the authors analyzed values of follicle-stimulating hormone, luteinizing hormone and prolactin in 50 women of reproductive age with normal menstrual cycles and established ovulation. Blood samples were taken 3-5 times during follicullar, ovulatory and lutheal phase of menstrual cycle. There were 582 radioimmunoassays performed (194 per each hormone), and the upper referent value for prolactin was 20.
