[Hormonal monitoring during the menstrual cycle among sterile women. II]

This paper attempts to assess the value of the dynamical examinations of the concentrations of the pituitary gonadotropin LH, FSH, PRL in the menstrual cycle. RIA were made on 22 sterile women with monophasic cycle and 119 sterile women with biphasic cycle in comparison with 17 women who delivered at least one child without previous treatment (control group). The dynamical RIA were made on all women between the 5th and the 26th day of the menstrual cycle. The results of these assays were compared in the 8th, 14th, 15th, 16th, 21st and 25th day of the menstrual cycle. It was confirmed that the lower levels of PRL are maintained through all the time of the menstrual cycle among sterile women with monophasic cycle. It is shown that higher level of LH is maintained through all the time of the menstrual cycle but it is particularly higher in the secretary phase of the cycle among sterile women with monophasic cycle. A lower level of FSH was observed at the beginning of the follicular phase of the cycle and a markedly higher concentration of FSH was found on the secretary phase of the cycle among sterile women with monophasic cycle.
