Zusammenfassung:Serial blood samples were taken from eight lactating women while they were nursing their babies 1–4 months postpartum, and from four lactating controls while they were not nursing. The plasma was assayed for oxytocin by radioimmunoassay after extraction with activated Vycor glass powder. In the suckling mothers mean plasma oxytocin rose from 5.4 pg/ml before nursing to 13.0 pg/ml during nursing. Oxytocin levels changed rapidly from minute to minute, with individual peaks as high as 54 pg/ml. Oxytocin levels in the control mothers averaged 4.4 pg/ml.
