Stimulatory and inhibitory influences of serum from pregnant women on aromatase activity of immature rat Sertoli cells

Effects of serum from pregnant women on basal and FSH (or cAMP) stimulated aromatase activity of immature rat Sertoli cells in primary culture were studied. These data suggest that human pregnancy serum contains factor(s) which may stimulate basal aromatase activity of Sertoli cells and may inhibit FSH-induced aromatase activity
