On the basis of the behaviour during menstrual cycle of the pituitary hormones plasma levels, the Authors have studied during the different periods of the cycle (follicular, ovulatory and luteal) the effects of OGTT and ITT's on the plasma levels of Glucose, insulin, HGH and Cortisol. Significantly lower levels of IRI, HGH and Cortisol were found in follicular phase compared to ovulatory period and luteal phase except for Cortisol in luteal phase. A slightly higher glucose tolerance was found in follicular phase as well as a reduced hypoglicemia under insulin load. Reduced HGH response to ITT was found in follicular phase as well as a reduced Cortisol response compared to the results observed in ovulatory and luteal phase. These data sustain the concept that hormonal variations occurring in an ovulatory cycle are also capable of modifying the woman's body response to various stimuli such as OGTT and ITT.
