The dynamics of prolactin level in blood women during the menstrual cycle

The particularities of Prolactin (PRL) level in the blood serum of women with maintaining menstrual cycle are investigated. It has the important signifity for diagnostics and threatment of transient hyperprolactinemia. The results of investigation have shown, that the PRL level in blood serum of women particularly fluctuated during menstrual cycle with growth in the second half of it. The optimal time of the blood sampling for PRL level measuring in the preserving menstrual cycle is the time of its maximal increase in the end of the hormonal cycle. The hormonal and menstrual cycle of women does not always correspond exactly by duration. The registration of rectal temperature may be used as the method of hormonal cycle control.
