Objective:
The menopause transition is a period of accelerated cardiovascular disease (CVD) development in women, and sex differences in CVD incidence are reduced after menopause. Higher plasma cyclic guanosine monophosphate (cGMP) levels are also associated with greater CVD risk. Thus, we examined the changes in cGMP levels associated with the menopause transition.
Methods:
We measured plasma cGMP levels in 511 women and 283 men in the Coronary Artery Risk Development in Young Adults (CARDIA) study.
Results:
Over a 20-year follow-up period, women who completed the menopause transition had smaller reductions in cGMP relative to women who remained premenopausal (P < 0.05) but had similar changes compared to men (P = 0.3) after adjusting for demographic variables.
Conclusions:
Plasma cGMP changes through the menopause transition may reflect the underlying mechanisms associated with greater cardiovascular disease risk.

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...
