[Release of ovulation by application of gonadotrophin as well as by radio-immunological assay of oestradiol and progesterone in serum (author's transl)].

The use of gonadotrophins to release ovulation is indicated for women with urgent desire for children and no positive response to clomiphene therapy. (Hence, a negative selection is made.) --The authors checked 100 therapeutic gonadotrophin series, with 69 patients involved. Oestrogens and progesterones were followed up by radio-immunological hormone analysis. --Ovulation occurred in 54 cases. Twelve patients developed ovarian reaction with oestrogen rise, while no ovarian response at all was recordable from 34 patients. Six women became pregnant under gonadotrophin therapy and two following the treatment. The results are compared with literature data.
