  • Title: [Naloxone-induced gonadotropin changes in females with amenorrhea].
    Author: Huber J, Knogler W, Schurz E, Spona J.
    Journal: Zentralbl Gynakol; 1987; 109(18):1143-8. PubMed ID: 3120439.
    Abstract:
    Along with 51 amenorrheic patients the pituitary reactional situation was checked by means of an Gn-RH-stimulation test. Simultaneously to all these women the opiate antagonist Naloxone was infused in a further test series. In 7 from 51 women a significant increase of the LH was demonstrated in comparison to the basic values. Comparing the kinetics of the pituitary gland it was evident, that in all cases the gonadotropin emanation was detective respectively missing after the second Gn-RH-bolus, which followed immediately after the first one. The findings seem to proof the thesis that the endorphins mainly influence the gonadotropin reserve capacity. In cases, where it was possible to objectify the influence--the second pool was missing as well.
