We present the results of immunoenzyme detection of inhibin B in blood serum of patients with adult-type granulosa cell tumors of the ovary. Blood concentration of inhibin B at the end of menstrual cycle in patients with tumor relapse was significantly higher than in patients during remission and in virtually healthy women. The increase in inhibin B concentration preceded clinical manifestation of the disease relapse by 2-13 months, which demonstrates high diagnostic sensitivity of this marker and suggests that it can be recommended for the use in diagnostics and monitoring of granulosa cell tumors of the ovaries.

Hormonal Control of the Ovarian Cycle
Before puberty, the hypothalamus releases GnRH in a low frequency, low amplitude pulsatile manner. This along with the immature hypothalamic-pituitary-gonadal axis activity, results in low estrogen levels and the absence of a fully functional ovarian cycle. At puberty, GnRH secretion increases in both frequency and...
