The effect of oral contraceptive pills on levels of oxytocin in plasma and on cognitive functions

Mood and Oxytocin Blood Levels in Physically Active Women with and without Oral Contraceptive Use in Relation to Seasonal Daylight Variation

“…Although we used an assay with a low respectively high limit of detection, Oxytocin values were below the limit (with OC, samples n = 2 and without OC, samples n = 2) and over the limit (with OC, samples n = 9 and without OC, samples n = 2), but are unlikely to affect statistical analyses; however supports the results of higher Oxytocin values in women with oral contraceptives [17].…”

“…A study by Silber, et al [17] showed no differences in hormonal levels of Oxytocin in plasma taken before and after breakfast, which supports the finding that minimal influence occurred if no breakfast was eaten. We are aware that our Oxytocin levels are somewhat high, but ELISA methodology is known to show higher results compared to RIA.…”

“…Oxytocin concentration has been shown to increase with estradiol administration [14,15] and in pregnancy there is evidence that the magnitude of the changes in circulating concentration is related to the estradiol/progesterone ratio [16]. A significant increase in Oxytocin levels has also been shown when women used oral contraceptives [17,18].…”

Diminished Nap Effects on Memory Consolidation Are Seen Under Oral Contraceptive Use

“…In this study, we did not find an effect of OC phase (active OC intake or OC-free interval) on memory. While some studies do report an OC phase effect [17,56], other studies do not find such an effect [57,58,59]. It does not seem too surprising that there was no phase effect on memory if one considers the range of absolute hormone values.…”

Ηθική Ενίσχυση, Ελευθερία Και Το Μηχάνημα Του Θεού

“…ση των επίπεδων της βασικής οξυτοκίνης και θεωρείται ότι ενισχύουν την έκκρισή της (Stock et al 1994;Silber et al 1987). Παρομοίως, τα γλυκοκορτικοειδή, τα οποία χρησιμοποιούνται ευρέως για την θεραπεία του άσθματος και άλλων φλεγμονωδών διαταραχών, πιστεύεται πως ρυθμίζουν τόσο την έκκριση της οξυτοκίνης, όσο και την έκφραση των υποδοχέων σεροτονίνης σε κάποια τμήματα του εγκεφάλου (Link et al 1993;Liberzon et al 1997).…”
