[The plasma and urinary hormone profiles during treatment with human gonadotrophins (author's transl)]

This study presents 6 cases of sterility that had anovulation or disturbances of ovulation treated by HMG HCG. Induction of ovulation was monitored by daily urinary oestrogen assays. The parallel study of the plasma profiles of oestradiol 17 beta, of FSH, and of LH obtained during the induction of ovulation show that the cycles in induced ovulation are not physiological in character. On comparison of the plasma profiles with the urinary profiles a significance delay is shown in the urinary oestrogen profile as compared with the plasma one and explains to a certain extent the results that were obtained.
