Ovaries in postmenopausal women synthesize steroids, mostly androgens. Removal of the ovaries after menopause may be reflected by menopausal symptoms and arterial hypertension observed during postoperative period, along with a significantly increased risk of death due to cardiovascular complications. It is not understood if the clinical consequences of gonad removal at different time points after menopause are similar. The aim of this study was to evaluate ovarian steroidogenesis and consequently to define the role of the ovaries in postmenopausal women depending on the time after menopause. Concentrations of hormones were determined in ovarian homogenates and serum of postmenopausal women. This study included 207 postmenopausal women. They were divided into groups depending on the time after menopause. All participants had laparotomic removal of the ovaries. Concentrations of estradiol, testosterone and androstenedione were measured in ovarian homogenate and serum. The study revealed that ovarian homogenate and serum concentrations of estradiol, testosterone and androstenedione were the highest in women up to 5 years after menopause and since then significantly decreased. This study showed that testosterone, androstenedione and estradiol are synthesized in the postmenopausal ovaries. The peak synthesis of these hormones occurs up to 5 years after menopause and significantly decreases thereafter.
