J. Taleb et al., 24 HOURS HORMONE-SECRETION PROFILES OF CORTISOL AND ESTRADIOL IN PRETERM LABOR, Hormone and Metabolic Research, 25(8), 1993, pp. 442-443
We investigated the 24 hour hormone secretion profiles in women with p
reterm labour. Although estradiol secretion seems to be unaffected, we
found an variable estradiol-cortisol-shift due to a cortisol increase
. Cortisol circadian secretion persists in preterm labour, but maximum
secretion is moved to midday. Further investigations are necessary to
study the basic mechanisms underlying this process.
