The aim of this study was to explore the direct action of noradrenaline and dopamine on progesterone and estradiol secretion of human granulosa cells cultured in serum-free medium. Progesterone and estradiol production was measured in the presence and absence of noradrenaline, dopamine or propranolol using radioimmunoassays; statistical analysis was performed by analysis of variance and Newman-Keul's multiple range test. Twenty-six women aged 31±3 years undergoing in vitro fertilization and embryo transfer for infertility treatment at University Women's Hospital, University of Tübingen, Germany, took part in this study. Noradrenaline significantly inhibited progesterone production by human granulosa cells in a dose-related manner at a concentration of 10−4–10−6 mol/l. Dopamine significantly stimulated estradiol secretion by granulosa cells in an inverse dose-related manner. Both effects were blocked by propranolol. The results suggest that catecholaminergic actions switch over the steroid production of human granulosa cells cultured in serum-free medium from progesterone to estradiol.

Stimulation Of

Unkei-to is widely used in traditional Japanese herbal medicine for its ovulation-inducing effect. In the present study, we investigated the in vivo effects of Unkei-to and its compounds on the steroidogenesis and cytokine secretion in human granulosa cells. Unkei-to stimulated the secretions of 17β-estradiol and progesterone from highly luteinized granulosa cells obtained from in vitro fertilization patients; the stimulated effect on estradiol secretion occurred with 0.3 μg/ml, while a significant effect on progesterone secretion was obtained at 10 μg/ml. The Unkei-to stimulation of estradiol secretion could be accounted for by the effects of its ingredients, Shakuyaku (paeoniae radix, Paeonia lactiflora Pallas) and Keihi (cinnamomi cortex, Cinnamomum cassia Blume); while dose response curves for Unkei-to and Keihi to induce progesterone production were superimposable. Exposure of the cells to Unkei-to caused dose-dependent increases in the concentrations of interleukin (IL)-1β, IL-6 and IL-8 in the culture medium. Similar results were obtained when cells were incubated with the ingredient Ninjin (ginseng radix, Panax ginseng C.A. Meyer), but not Shakuyaku and Keihi. These results indicate that Unkei-to has direct stimulatory effects on human granulosa cells to stimulate the steroidogenesis and secretion of cytokines (IL-1β, IL-6 and IL-8). The various beneficial actions of Unkei-to on the ovary may result from a combination of different ingredient herbs with different stimulatory effects on both steroidogenesis and the ovulatory process within the ovary, as well as stimulatory effect on the hypothalamus-pituitary axis.
