Abstract:
This article presents circadian variation in salivary oxytocin levels in a sample of 91 female participants, including 47 healthy controls and 44 patients with borderline personality disorder (BPD). A significant increase in salivary oxytocin levels was observed between awakening and early afternoon. There were no significant group differences and no Group × Time interaction. These findings have implications for research conducted in the field and suggest the need to control for time of assessment, as done in studies assessing cortisol.

The time of drug administration is an important factor to consider, as it can influence the toxic dose of a drug. For example, a study conducted by Prins et al. in 1997 examined the effects of the timing of...
Hormonal Regulation of the Menstrual Cycle
At puberty, GnRH begins a pulsatile release pattern, which triggers the anterior pituitary gland to secrete follicle-stimulating hormone (FSH) and luteinizing hormone (LH). The frequency and amplitude of GnRH pulses vary across the menstrual cycle, with faster pulses favoring LH release and slower pulses favoring FSH...
