The remaining 9 women were given daily a capsule which contained either colchicine 1.2 mg. or a placebo, according to a double-blind crossover study plan. The medication was given from the first day of a menstrual cycle until vaginal bleeding again began, and endometrial biopsies were performed during the last half of each cycle to determine if ovulation had occurred. Results are outlined in Fig. 1. Ovulation did not occttr in 1 woman who was taking colchicine.
