Elevated serum progesterone concentrations during the early follicular phase of the menstrual cycle: Clinical significance and therapeutic implications

Abstract

This study describes the incidence and clinical significance of hyperprogesteronemia in the early follicular phase of the menstrual cycle and the effects of prednisolone treatment in patients with this condition. Progesterone, testosterone and dehydroepiandrosterone sulfate (DHEAS) serum concentrations were determined in 316 consecutive patients admitted for infertility treatment. Elevated concentrations of progesterone in the early follicular phase could be detected in 36 cases (11.4%). In these patients, elevated testosterone and DHEAS concentrations could be detected in eight and ten cases, respectively. Serum concentrations of 17α-hydroxyprogesterone and Cortisol were normal in all patients. Treatment with 2.5-7.5 mg prednisolone/day normalized progesterone serum concentrations within 4-8 weeks. Twenty-four patients achieved a pregnancy either by timed intercourse or by intrauterine insemination (IUI) over the following 12 months.
