Abstract:
OBJECTIVE:To investigate the serum pattern of free leptin, bound leptin, and soluble leptin receptor throughout the physiological menstrual cycle. DESIGN:Prospective observational study. SETTING:Tertiary care center for gynecological endocrinology and reproductive medicine and a university research laboratory. PATIENT(S):Thirty regularly cycling volunteers (age, 29 +/- 4.2 years). INTERVENTION(S):Blood sampling was performed at different phases (early and mid follicular phase, preovulatory phase, and early and late luteal phase) of three consecutive menstrual cycles; each phase of the menstrual cycle was investigated twice. MAIN OUTCOME MEASURE(S):Free leptin, bound leptin, soluble leptin receptor, LH, E(2), P, vaginal ultrasound. RESULT(S):A peak of serum free leptin levels was found in the late luteal phase followed by a significant drop in the early follicular phase and again by a continuous increase up to the next luteal peak. There were no significant alterations in serum bound leptin and soluble leptin receptor levels. CONCLUSION(S):The present study shows that there are significant circacyclic fluctuations of free leptin levels with the highest concentrations in the late luteal phase and the lowest levels in the early follicular phase, which suggests that circulating free leptin is up-regulated by the C(21)-steroid (P). Circulating bound leptin and soluble leptin receptor are not altered by the cyclic hormone status. The significant rise of the leptin bioequivalent, free leptin, in the late luteal phase might be of importance for the luteal-follicular and the luteal-preimplantatory functional shift.
