Background:
Oral contraceptives (OCs) affect mood in some women and may have more subtle effects on emotional information processing in many more users. Female carriers of mineralocorticoid receptor (MR) haplotype 2 have been shown to be more optimistic and less vulnerable to depression.
Aim:
To investigate the effects of oral contraceptives on emotional information processing and a possible moderating effect of MR haplotype.
Methods:
Cross-sectional study in 85 healthy premenopausal women of West-European descent.
Results:
We found significant main effects of oral contraceptives on facial expression recognition, emotional memory and decision-making. Furthermore, carriers of MR haplotype 1 or 3 were sensitive to the impact of OCs on the recognition of sad and fearful faces and on emotional memory, whereas MR haplotype 2 carriers were not.
Limitations:
Different compounds of OCs were included. No hormonal measures were taken. Most naturally cycling participants were assessed in the luteal phase of their menstrual cycle.
Conclusions:
Carriers of MR haplotype 2 may be less sensitive to depressogenic side-effects of OCs.

01:22Hormonal 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...
