[Ovulation induction by cyclofenil (author's transl)].

The ovulation-inducing action of cyclofenil was investigated in 135 sexually mature women aged 20--35 years. The patients were only included in the trial if no ovulation in 2 consecutive cycles with the following criteria: basal temperature, cervix score, ascorbic acid retention, basophil count, serum hormone levels, e. g. LH and progesterone and the estrogens in the 24-hour urine could be determined. Ovulation was only considered to have occurred when all the parameters named indicated it. The lack of ovulation was accompanied by amenorrhea in 21 of the 135 patients. The ovulation rate in the 241 cycles observed was 101, corresponding to 42%. In the 114 patients with anovulatory cycles, the ovulation rate in the 184 cycles observed was 95, corresponding to 50%. In the 21 amenorrheic patients, ovulation occurred 6 times in the 57 cycles observed. Nausea or vomiting occurred as side effects in only 2 cases.
