Objective: We aimed to investigate plasma oxytocin level in women with natural and surgical menopause and its relation with other metabolic parameters. Methods: This study included 89 postmenopausal women admitted to menopausal outpatient clinics and gave written consent to participate. Participants were allocated into natural (Group 1; n = 61) and surgical (Group 2; n = 28) menopause groups based on causative process for the onset of menopause. After the clinical evaluation and physical examination, blood samples are collected for biochemical profile and plasma oxytocin levels. The complete blood count, lipid profile, thyroid panel, blood glucose concentration, vitamin D and liver enzymes were measured by autoanalyzer, plasma oxytocin level was measured spectrophotometrically by ELISA method. Results: The groups were comparable for age, body mass index, menopause duration, gravity and blood parameters measured except significantly different plasma oxytocin levels between the two groups as 6.8 (3.2–20.6) ng/ml in natural menopause group and 4.2 (2.9–18.2) ng/ml in surgical menopause group (p < 0.001). Plasma oxytocin level was also negatively correlated with age (r = −0.245, p = 0.022) and menopausal duration (r = −0.275, p = 0.01). Conclusion: Our results point out that oxytocin might be a target hormone to manage menopause associated disorders and/or it should be considered for its role in the differences in the incidences of postmenopausal diseases and quality of life in the course of natural and surgical menopausal transition.
