Brief Summary
Evaluation of the effect of a single dose of CDB-2914, as compared to placebo, administered after the onset of the LH surge on the outcome of the leading ovary follicle:
- echographic follicle rupture
- inhibition of follicle rupture
- luteal phase progesterone levels
- anovulatory progesterone levels

Outcome Measures
Primary Outcomes (1)
Inhibition of follicular rupture
Inhibition is calculated as the number of subjects exhibiting no dominant follicle rupture, divided by the total number of subjects having received treatment
within 6 days after treatment intake
Secondary Outcomes (7)
Appearance or absence of a corpus luteum
during the 6 days following treatment intake
Growth pattern of leading follicle
Presence or absence of a surge of serum luteinizing hormone (LH) levels
Menstrual cycle length in comparison to the subject's reported baseline average cycle length and to her placebo-treated cycle length
Incidence of intermenstrual bleeding and treatment-emergent adverse events
- +2 more secondary outcomes
