This paper evaluates the hormonal profile of infertile women with an ovulatory menstrual cycle. The hormones studied were pituitary derived FSH, LH, and PRL, measured by radioimmuassay. The measurements were conducted 8 times on specified days of the menstrual cycle. The examination involved a group of 98 women heretofore unable to conceive and a control group of 32 women who had conceived at least one child prior to treatment. Statistical analysis of the mean hormonal concentration values found that the FSH levels in women of both groups were similar during the whole menstrual cycle except on the day of ovulation when it was significantly higher in the group of infertile women. The mean value of LH concentrations in this group of women unable to conceive was significantly higher during the whole menstrual cycle. The prolactin level in both groups was statistically similar overall; prolactin levels were statistically lower in the group of infertile women on only two days of the menstrual cycle, one before and one after ovulation.
