title: [Inhibition of ovulation with 17-alpha-ethinyl-18-methyl-11-methylene-4-estren-17-ol plus ethinylestradiol].
abstract: A combined oral application of 30 micrograms ethinylestradiol with 50 micrograms 17 alpha-ethinyl-18-methyl-11-methylene-4-estren-17-ol (a newly developed progestagen) -- for 21 days resulted in a distinct antigonadotrophic effect, shown by hormone analysis (LH, FSH, estradiol and progesterone) in serum samples of three healthy and fertile women. A final recommendation on the daily dosage, however, depends on the results of clinical experimental investigation still in progress.
